It would be that because the y intercept is 4 so that leaves us two options:
y=3x + 4 and y = -3x +4
Because the line is going down as you move across the x-axis, we know the slope is negative so y = -3x + 4 is your final answer

What is the area of a rectangle with vertices (-8, -2), (-3,-2).(-3,-8), and (-8, -B)?
Answers
Answer:
The area of the rectangle would be 20 square units.
Step-by-step explanation:
The distance between the points (-8, -2) and (-3,-2) is 5. This is the length of the rectangle. The distance between (-3,-6) and (-3,-2) is 4. This is the width of the rectangle. To find the area, multiply the length and the width to get the 20 square units as the area.
Answer:
Area = 20
As B = -4
Where -3-1 = -4
We look at x for first measure = -8 -3 = 5
We look at y first sequence change for second measure = -B
x/y = -3-8 /-8 + B
= -3-8 = -8(-8)+B
B = -3+B = -3+1
B= -3+1 = -4
Second measure = -8-4 = 4
Therefore, using both measures in bold : the Area = 4 x 5 = 20

Answers
Answer:
5.5
Step-by-step explanation:
Each can holds 2 liters of paint. There is 11 liters of paint. The question is asking you to figure out how many cans of paint you can fill with 11 liters of paint. We can divide 11 by 2 to get the answer. 11÷2=5.5. The reason this works is because we are dividing the total amount of paint by how much each can will hold. 5.5 can also be written as "five and a half". So, the 11 liters of paint will fill 5.5 cans.

4n^2 + 24n + 36
Answers
Answer:
(2n+6)^2
Step-by-step explanation:
To solve this, you can use the given formula: x^2 + 2xy + y^2
In this case, 4n^2 is x^2, 24n is 2xy, and 36 is y^2. The next step is:
(2n)^2 + 2(2n)(6) + (6)^2
Since this equation fits into this formula ( x^2 + 2xy + y^2), we can do:
(2n+6)(2n+6) =
(2n+6)^2
Hence, the answer is (2n+6)^2

Answer:
(2, 7, 2)
Step-by-step explanation:
z=2, so we have:
x=2y-6z (this becomes x=2y-12)
-5x-2y=-24 (since there are no z's in this equation, we can't do anything.)
x-2y=-12
-5x-2y=-24
We can use the method of elimination to solve this system of equations, but first, to do that, we must multiply the top equation by -1
-x+2y=12
-5x-2y=-24
Now, the 2y and -2y can cancel out!
-6x=-12
x=2
If x=2, we can substitute that into this equation: x-2y=-12.
And we get: 2-2y=-12
Subtract 2: -2y=-14
y=7
Finally, we have our answer: x=2, y=7, z=2.

Determine if triangle DEF with coordinates D(2,1), E(3,5), and F (6,2) is an equilateral triangle. Use evidence to support your claim
Answers
Answer:
No, it is isosceles.
Step-by-step explanation:
(In assumption that the points have been plotted on a graph)
After the points have been plotted we need to find the distance between each set of points. DE, DF, and, EF.
Finding DE and DF
To find DE and DF, we need to do some counting. From point D to point E, we travel 2 units right, and 8 units up forming an imaginary triangle with a right angle. From D to F, we again travel 8 units right and 2 units up, forming the same triangle, just oriented slightly differently.
Using the Pythagorean Theorem ([tex]a^2 + b^2 =c^2[/tex]) we can plug in some values to find C and two of our side lengths.
[tex]a^2+b^2=c^2[/tex]
[tex]2^2+8^2=c^2[/tex]
[tex]4 + 64 = c^2[/tex]
[tex]68=c^2[/tex]
[tex]\sqrt{68} =c[/tex]
[tex]8.25=c[/tex]
The lengths of DE and DF are both roughly 8.25
Finding EF
Finding EF is going to be the same process but just a little different.
If we start at E and travel to F, we move down 6 units and right 6 units, forming another right triangle. now we use the Pythagorean Theorem ([tex]a^2 + b^2 =c^2[/tex]) again, to find C and the length of EF.
[tex]a^2 + b^2 =c^2[/tex]
[tex]6^2+6^2=c^2[/tex]
[tex]36+36=c^2[/tex]
[tex]72=c^2[/tex]
[tex]\sqrt{72} =c[/tex]
[tex]8.49=c[/tex]
The length of EF is roughly 8.49 units.
Since not all of the sides of the triangle are the length, triangle DEF is not equilateral. Instead triangle DEF is isosceles.

No it is isosoles

1/2x = 15

Answers
Answer:
-1.3
Step-by-step explanation:
you can ignore this + in this question. In mathematics we write it as
4.6 + -5.9
It says + a negative number, which is almost like saying "I am going outside with without my jacket..." And that means I go outside without it. The same goes here...
In mathematics the rule is (+ * - ) = -
4.6 - 5.9 = -1.3
EXTRA:
Whenever you are dealing with negative numbers, you can think of the numbers as if it is about temperatures...
Suppose you have a temperature of 4.6 degrees and then it gets colder with an "amount" of 5.9 degrees. This of course accounts for a negative temperature of 1.3 degrees... ( because 4.6 + 1.3 = 5.9)
So - 1.3

What are the coordinates of the vertex of the function f(x)=x^2+10x−3? (–5, –28) (–5, 28) (5, –28) (5, 28)
Answers
Answer:
(-5,-28)
Step-by-step explanation:
Given
[tex]f(x)=x^2+10x - 3[/tex]
Required
Find the coordinates of the vertex
Given that the function is a quadratic function;
The general form of a quadratic function is
[tex]f(x)= ax^2+bx +c[/tex]
By comparison;
[tex]a = 1\ b = 10\ and\ c = -10[/tex]
To calculate the coordinates of the vertex;
we start by calculating the x-coordinate;
[tex]x = \frac{-b}{2a}[/tex]
Substitute 10 for b and 1 for a
[tex]x = \frac{-10}{2*1}[/tex]
[tex]x = \frac{-10}{2}[/tex]
[tex]x = -5[/tex]
Substitute [tex]x = -5[/tex] in the given function;
[tex]y=x^2+10x - 3[/tex]
[tex]y=(-5)^2+10*-5 - 3[/tex]
[tex]y=25-50 - 3[/tex]
[tex]y=-28[/tex]
Hence, the coordinates of the vertex is (-5,-28)

A coin bank contains $3.55 in quarters, dimes, and nickels. The number of
dimes is four less than the number of quarters and the number of nickels is
seven more than the number of quarters. Find the number of quarters.
Answers
Answer:
9 quarters
Step-by-step explanation:
Total cost of money in the coin bank = $3.55
Let the number of dimes be = d
Let the number of quarters be = q
Let the number of nickels be = n
Where:
1 quarter = $0.25
1 dime = $0.1
1 nickel = $0.05
Hence,
0.1(d) + 0.25(q) +0.05(n) = $3.55
In the question, we are told that:
The number of dimes is four less than the number of quarters, mathematically
d = q - 4
The number of nickels is seven more than the number of quarters, mathematically,
n = q + 7
From the question, we are ask to find q
0.1(d) + 0.25(q) +0.05(n) = $3.55
since d = q - 4
n = q + 7
We substitute
0.1(q - 4) +0.25( q )+ 0.05(q + 7) = $3.55
0.1(q - 4) +0.25( q )+ 0.05(q + 7) =$3.55
0.1q - 0.4 +0.25q + 0.05q + 0.35 = $3.55
Collect like terms
0.1q + 0.25q + 0.05q = 3.55 + 0.4 - 0.35
0.4q = 3.6
q = 3.6/0.4
q = 9
Therefore the number of quarters is 9.

Paula Pidcoe is doing her budget. She discovers that the average miscellaneous expense is $65.00 with a standard deviation of $18.00. What percent of her expenses in this category would she expect to fall between $54.20 and $86.60?
Answers
Answer:
61.06%
Step-by-step explanation:
First, we need to find the z-score for 54.2 and 86.6 using the following equation:
[tex]z=\frac{x-m}{s}[/tex]
Where m is the mean and s is the standard deviation. So, the z-scores are calculated as:
[tex]z=\frac{54.2-65}{18}=-0.6\\ z=\frac{86.6-65}{18} =1.2[/tex]
Finally, the percent of her expenses that she would expect to fall between $54.20 and $86.60 are calculated as:
P(54.2 < x < 86.6) = P(-0.6 < z < 1.2)
So, using the normal table, we get:
P(-0.6 < z < 1.2) = P(z < 1.2) - P(z < -0.6)
P(-0.6 < z < 1.2) = 0.8849 - 0.2743
P(-0.6 < z < 1.2) = 0.6106
The percent is 61.06%
Find the average rate of change of the function
f(x) = x² + 9x from x1 = 1 to x2 = 5.
Answers
Answer:
15
Step-by-step explanation:
The function is;
f(x) = x² + 9x
We are to find the average rate of change from point [tex]x_{1}[/tex] = 1 to point [tex]x_{2}[/tex] = 5
Average rate of change = [tex]\frac{f(x+h) - f(x)}{h}[/tex] where h is the change in x-axis
When x = 1 , f(x) = 1² + 9(1) = 10
When x = 5, f(x) = 5² + 9(5) = 70
f(x + h) - f(x) = 70 - 10 = 60
h = 5 - 1 = 4
So average rate of change = [tex]\frac{60}{4}[/tex] = 15
The average rate of change of the function f(x) = x² + 9x from x₁ = 1 to
x₂ = 5 will be 15.
What is Average rate?
The average rate change is defined by divide the change in y - values by the change in x - values.
Given that;
The function is defined as;
⇒ f(x) = x² + 9x ; from x₁ = 1 to x₂ = 5
Now,
The formula for the average rate change is given as;
Average change = f (x + h) - f (x) / h
Where, h is change in x - axis.
Since, The function is;
f(x) = x² + 9x
When, x₁ = 1
f(x) = x² + 9x
f(1) = 1² + 9
f (1) = 10
When, x₂ = 5
f(x) = x² + 9x
f(x) = 5² + 9 x 5
f (5) = 25 + 45
f (5) = 70
So, Average change = f (x + h) - f (x) / h
Average change = 70 - 10 / (5 - 1)
= 60 / 4
= 15
Thus, The average rate of change of the function f(x) = x² + 9x from x₁ = 1 to x₂ = 5 will be 15.
