Answer:
Discriminant = -92
the equation has no distinct real numbers
Step-by-step explanation:
Given the function f(x) = 4x^2 + 2x + 6 where;
a = 4, b = 2 and c= 6
The discriminant is expessed as D = b^2 - 4ac
Substitute;
D = 2^2 - 4(4)(6)
D = 4 - 96
D = -92
Hence the discriminant is -92.
Since the discriminant is less than zero i.e D< 0, this shows that the zeros of the equation are not real but complex numbers. Hence, the equation has no distinct real numbers
Answer:
-92 is the discriminant
0 real value 0's

Answer:
a. Line A and line C
b. Line B
c. Line A and line C
Step-by-step explanation:
a. Negative slopes slant downwards from your left to the right. Thus, line A and line C are negative slopes.
b. The line with the steepest slope is the line that appears to slant the more, whether downwards to the right or upwards to the right.
Line B appears to slant the more. Therefore line B has the steepest slope
c. The slope value of line A, that is rise/run = 4.
The slope value of line C = 4 also.
Parallel lines have the same slope value. Therefore, line A and C are parallel.
shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function. which statement is true?
Answer:
The given equation will have two roots as +5i and -5i
Step-by-step explanation:
Shasta claimed that the equation x^2+25=0 can be solved by using its factored form of (x+5i)^2=0, and that -5i is the only zero for this function
The given equation is [tex]x^2+25 =0[/tex]
This clearly shows it will have complex roots, and since it is a quadratic equation it will have 2 complex roots
[tex]x^2 = -25 \\x = \sqrt{-25} \\x= \sqrt{-1}* \sqrt{25}\\[/tex]
[tex]x = i\sqrt{25}[/tex]
x = ± 5i
It will be false to say that -5i will be the only complex root to this equation.
The given equation will have +5i and -5i as its roots.
Lets verify
x = +5i
[tex](5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25\\-25 + 25 = 0[/tex]
x = -5i
[tex](-5i)^2 + 25 \\25i^2 + 25 \\25(-1) + 25 \\-25 + 25 \\ = 0[/tex]

20 balloons have to be devided between a group A and Group B in the ratio 2:3. How many balloons will each group receive?
Answer:
There are 8 and 12 balloons for groups A and B, respectively.
Step-by-step explanation:
The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:
Group A
[tex]n_{A} = \frac{2}{2+3}\cdot (20)[/tex]
[tex]n_{A} = 8[/tex]
Group B
[tex]n_{B} = \frac{3}{2+3}\cdot (20)[/tex]
[tex]n_{B} = 12[/tex]
There are 8 and 12 balloons for groups A and B, respectively.

x = 7
Step-by-step explanation:
We assume the hash marks are intended to indicate both triangles are isosceles. Then the right-end angle of the upper triangle is ...
180° -2(75°) = 30°
Its complement is the supplement of the "missing variable" angle.
90° -30° = 180° -(18x -6)°
18x = 126 . . . . . rearranging (add 18x -60)

Good Morning :^)
Question:
Yesterday, Bethany sent 60 text messages. She said that 15% of those
messages were to her best friend. How many text messages did Bethany
send to her best friend yesterday?
Well, let's figure this out!
Y is 15% of 60
Equation: Y = P% × X
First Step: Solve our equation for Y
Y = P% × X
Y = 15% × 60
Second Step: Convert percent to decimal:
p = 15%/100 = 0.15
Y = 0.15 * 60
Y = 9

To find:
The system of equations for the given problem.
Solution:
Let x be the number of correct answers and y be the number of wrong answers.
Total question answered by Steve = 30
[tex]x+y=30[/tex] ...(i)
Steve gets 4 points for every correct answer and loses 1 point for every wrong answer.
Score for 1 correct answer = 4
Score for x correct answer = 4x
Score for 1 wrong answer = -1
Score for y correct answer = -y
Total score = 20 points

Step-by-step explanation:
Number 1:
Remember: Diagonals are congruent (in this case scenario).
Remember: Consecutive angles are supplementary.
☆You are going to subtract 60 from 18p. (You are subtracting it from 180 specifically because the angles are on a straight angle, and a straight angle equals 180 degrees.)
[tex]180 - 60 = 120[/tex]
^Hence your answer^
Number 2:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 154 from 180.
[tex]180 - 154 = 26[/tex]
Number 3:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 35 from 180.
[tex]180 - 35 = 145[/tex]
Number 4:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 85 from 180.
[tex]180 - 85 = 95[/tex]
Number 5:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 51 from 180.
[tex]180 - 51 = 129[/tex]
Number 6:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 82 from 180.
[tex]180 - 82 = 98[/tex]
Every day, the Clinton Pet Store uses 3 bags of dog food to feed the dogs. How many days will 3/4 of a bag of dog food last?
3/4 of a bag of dog food will last for 2.25 days.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
If 3 bags of dog food are used every day, then in one day, 1 bag of dog food will last:
1 day = 1/3 bag of dog food
To find how many days 3/4 of a bag of dog food will last, we can divide 3/4 by 1/3:
(3/4) ÷ (1/3)
= (3/4) × (3/1)
= 9/4
= 2.25
Therefore,
3/4 of a bag of dog food will last for 2.25 days.

Answer:
I would say it's B. false
Answer:
False
Step-by-step explanation:

Madelyn has a total of 15 dimes and quartets in her piggy bank. The total amount of money in her piggie bank is $2.85. Write and solve a system of equations to determine the number of dimes and the number of quarters in madelyn’s piggie bank.
The system of equations is x + y = 15 and 0.10x + 0.25y = 2.85. Then the number of dimes and quarters will be 6 and 9, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Madelyn has a total of 15 dimes and quartets in her piggy bank. The total amount of money in her piggy bank is $2.85.
Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equations are given as,
0.10x + 0.25y = 2.85 ....1
x + y = 15 ....2
From equations 1 and 2, then we have
0.10(15 - y) + 0.25y = 2.85
1.5 - 0.10y + 0.25y = 2.85
0.15y = 1.35
y = 9
Then the value of the variable 'x' is given as,
x + 9 = 15
x = 6
The system of equations is x + y = 15 and 0.10x + 0.25y = 2.85. Then the number of dimes and quarters will be 6 and 9, respectively.

Joshua is making spaghetti and meatballs for dinner for his friends. Joshua makes 30 meatballs. If Joshua wants 5 meatballs on each plate of spaghetti, how many plates can Joshua make? Write an equation to represent the scenario, and solve.
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
Given
Let y represent the number of meatballs in total and x represents the number of plates.
[tex]y = 30[/tex]
[tex]Rate = 5[/tex] per plate
Required
Determine the value of x
To solve for x, we make use of the following expression.
[tex]y = Rate * x[/tex]
Substitute values for y and Rate
[tex]30 = 5 * x[/tex]
[tex]30 = 5 x[/tex]
Divide through by 5
[tex]30/5 = 5 x/5[/tex]
[tex]6 = x[/tex]
[tex]x = 6[/tex]
Hence, number of plates is 6

Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.
He has 72 pencils and 24 calculators and he must use all of the pencils and calculators.
If Zayed creates the greatest number of identical packages possible, how many pencils will be in each package?
Answer: 3 Pencils
Step-by-step explanation:
In order to know how many packages Zayed can make, we need a number that is a factor of 72 and 24, so that the 72 pencils and the 24 calculators can be divided evenly.
So, if there wre 2 packages, there would be 72 / 2 = 36 pencils 24/ 2= 12 calculators in each package. This creates packages, but isn't the gratest number of packages!
To find the greatest number of identical packeges, we want to found the greatest common factor of 72 and 24
To do so, lets find the factors of 72 and 24
72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
24: 1, 2, 3, 4, 6, 8, 12, 24
the gratest common number factor of 72 and 24 is 24. in math notation this looks like:
gcf (72, 24)=24
the gratest number of identical packages can make is 24
To find the umber of pencils in each pacage, we need to dovide the total number of pencils by the number of pakages:
72 / 24 = 3.
there will be 3 pencils each package
