8 because 4^2 is equal to 16 and the half of 16 is 8
Answer:
y=-4x-8
Step-by-step explanation:
use points (0,-8) and (-2,0) and plug into slope formula.
slope formula=(y2-y1)/(x2-x1)
(0-(-8))/(-2-0)=-4
you get y=4x+b
use point (-2,0) to find b
you get y=-4x-8
Answer:
The value of x + y is -16.
Step-by-step explanation:
If each term is calculated by multiplying the previous one times 5 and then subtracting 20 from that result, then we can use that information to relate the first term (x) and the second one (0).
Following the info above, the following equation applies:
0 = 5 x - 20
then we solve for x:
5x = 20
x = 20/5
x = 4
Now we do the same study relating the second term (0) and the third one (y):
y = 5 (0) - 20
y = -20
Now that we have the value for both unknowns, we can estimate what they ask you: The value of x + y:
x + y = 4 + (-20) = 4 - 20 = -16
Answer:
The value of v is 3/4.
Step-by-step explanation:
First, you have to convert mixed number into improper fraction :

In order to find the value of v, you have to substract 3/4 to both sides :
