question Step-by-step explanation:
what is the positive value of x in the following expression?
[tex]2x ^{2} - 7x - 4[/tex]
Answer:
x = 4
Step-by-step explanation:
Given
2x² - 7x - 4
To solve for x , equate the expression to zero
2x² - 7x - 4 = 0 ← in standard form
(x - 4)(2x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - [tex]\frac{1}{2}[/tex]
Thus the positive value of x is x = 4
Answer:
x=4

May someone please help me?
Answer:
x=8°
y=29°
Step-by-step explanation:
vertically opposite angles are equal
so 5x+9°=y+20°
therefore 5x-y=11°
Alternate angles are equal
so 4x+17°=y+20°
therefore 4x-y=3°
equation 1....... 5x-y=11°
equation 2......4x-y=3°
using elimination method x=8°
y=29°

Four banks have provided proposals for a savings account. Which scenario provides exponential growth that will best benefit the account holder?
A.The deposit increases by 3%, percent of its current value, compounded annually.
B.The deposit increases by 3%, percent of its current value, compounded monthly.
C. The deposit increases by 5%, percent of its initial value each year.
D. The deposit increases by 0.40% point, percent of its initial value each month.
Answer:
B. The deposit increases by 3% of its current value, compounded monthly.
Step-by-step explanation:
When compounded monthly that means the account is getting more money monthly rather than annually, or each year, so this answer choice would give the best benefit to the account holder. I did this problem on Khan Academy myself and this was the correct answer.

What’s the angles measure for QPM??
Answer:
∠ QPM = 68°
Step-by-step explanation:
The measure of the chord- chord angle QPM is half the sum of the arcs intercepted by the angle and its vertical angle, that is
∠ QPM = [tex]\frac{1}{2}[/tex] ( LM + LK )
= [tex]\frac{1}{2}[/tex] ( 76 + 60)°
= [tex]\frac{1}{2}[/tex] × 136°
= 68°

Amadahy wants to buy a card and two gifts for her friend. Cards cost 3.49 each and gifts cost $10.63 each. Amadahy has a 20$ bill. Does she have enough to buy these items? If so, how much change will she receive? Will she receive? If not, how much more money does she need
Answer:
Given that Amadahy has a $ 20 bill, and wants to buy a card and two gifts for her friend, and knowing that each card costs $ 3.49 and each gift costs $ 10.63, the total cost of the 3 items would be $ 24.75 (10.63 x 2 + 3.49 ).
Therefore, she will not be able to purchase the products she wants, since she will need $ 4.75 to reach the amount necessary for it (24.75 - 20).
Marcus solved a problem and found out that 190% of 20 is 380. Is he correct
Answer: He is Incorrect, It's 38
Work: For this question, I did the Cross-Product Method. The Cross Product Method is when you solve equation via to fractions. With the CPM, One one side of the fraction, I had x / 20 (Twenty being the whole number) and on the other side, I had 190/100 (190 being the percent) After setting this up, I made the equation. 190 times 20 is 3800, and the other multiplication is 100 times x which is 100x. So, the new equation is 3800 = 100x. I divided both sides by 100, and the answer is 38 = x
I hope this helps, and Happy Holidays! :)
Answer:
No, Marcus is not correct. He converted the percent to a decimal correctly and he multiplied correctly, but he put the decimal in the wrong place in the answer. There should be two decimal places in the answer, so the answer should be 38.

Use the pencil,plot the point (3 1/2, 2 3/4)
Answer:
The diagram of the plotting point [tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)[/tex] is attached below.
Step-by-step explanation:
Given the points
[tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)[/tex]
as
[tex]3\frac{1}{2}=\frac{7}{2}=3.5[/tex]
[tex]2\frac{3}{4}=\frac{11}{4}=2.75[/tex]
so the point can be visualized as:
[tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)[/tex]
Now, we can check the point x = 3.5, and determine the corresponding value y = 2.75 and plot the point at the location (x, y) = (3.5, 2.75)
The diagram of the plotting point [tex]\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)[/tex] is attached below.

I just took the quiz
sin^2a-sin^2b=cos^2b-cos^2a
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then sin²x = 1 - cos²x
Consider the left side
sin²a - sin²b
= (1 - cos²a) - (1 - cos²b)
= 1 - cos²a - 1 + cos²b
= cos²b - cos²a
= right side , thus verified

Answer:
[tex]\huge\boxed{\sf Star = 14}[/tex]
Step-by-step explanation:
Let snowman be x , star be y and shopping bag be z.
So, the given equations are:
1) x + y = 20 (Eq. 1)
2) z = x + x
z = 2x (Eq. 2)
3) z + x = 18 (Eq. 3)
Put Eq. (2) in Eq. (3)
2x + x = 18
3x = 18
Divide both sides by 3
x = 18 / 3
x = snowman = 6
Now, Put x in (Eq. 1)
6 + y = 20
Subtract 6 to both sides
y = 20 - 6
y = 14
So,
Star = 14

~AH1807Find the slope (if defined) of the line that passes through the given points. (-1, 6) and (5, 5)
The solution for your question is-1/6
Answer:
- 1/6
Step-by-step explanation:
Use the following equation to calculate slope between two points:
( Y2 - Y1 ) / ( X2 - X1 )
What's Y2? Y1? X2? X1?
( -1, 6 )
-1 = X1
6 = Y1
( 5, 5 )
5 = X2
5 = Y2
So when we plug in those numbers:
5 - 6 = - 1
5 - (-1) = 6
- 1/6
Solve the system by substitution
Answer:
(x,y) = (-36,6)
Step-by-step explanation:
-6y=x
x+y=-30
x=-6y,
so -6y+y=-30
-5y=-30
y=6
x=-36
Hope this helps pls hit the crown :D
