f(x) = -4x^2 – 7x + 4
Find f(-7)
Answer:
-143
Step-by-step explanation:
you plug -7 in the x variables
-4(-7)^2-7(-7)+4 = -143
-(7-9)z-6z=8(-6+2) solve for z
can I see the process I know the answer is 8 I just don't understand the process
Answer:
(-(7-9))(z)-6z= 8(-6+2)
Simplify
-(-2)(z) -6z =8(-6+2)
Multiply 8*-6 and 8*2
2z -6z= -48+16
Combine like terms
2z+-6z =-32
-4z=-32
Divide both sides by -4
z=8

Solve for x and then find the measure of B
Answer:
x=6
b= 126
Step-by-step explanation:
8x+78 = 2x+114
8x-2x = 114-78
6x=36
x=6
--------
b=2x6+114
b= 126

60% of 15 is what answer
Answer:9
Step-by-step explanation:
Think of it this way:
If 15=100%
then x= 60%
So what you do is you multply 60 times 15 and divide it by 100 to give you the answer of 9. To me this is the simplest way to do it, I believe it’s called butterfly multiplying. You cross multiply and then you divide.
Someone buys 6 cakes for 8$ each he sells them for ten each then he got 8 more and selled them for 10$ how much money does he have left???
Answer: $28
Step-by-step explanation:
The person bought 6 cakes for $8 which reduces his money by:
= 6 * 8
= -$48
He then sells them for $10 each so the money made was:
= 10 * 6
= $60
He then buys 8 more for the same price which will reduce his money by:
= 8 * 8
= -$64
He sells these 8 for $10 so the money made was:
= 8 * 10
= $80
Total money left is therefore:
= 60 + 80 - 48 - 64
= $28

Answer:
y = (2/3)x + 7
Step-by-step explanation:
Slope intercept form is y = mx +b
1) We start off with y =
2) m = slope. Since we know that the slope is 2/3 we can plug it in. y = 2/3x
3) b is y-intercept which = 7.
Put it all together: y = 2/3 x + 7
3. Use the equation to answer the following question. 3x2 + 7x - 20 = 0 What are the solutions of the equation?
