Answer:
y= -7x-8
Step-by-step explanation:
The slope intercept form is y = mx + b.
First, find the slope. Use rise/run which gives you -7. <= negative bc its a negative slope.
Next, find the y intercept for b. It is -8.
Now, combine the numbers. y = -7x-8.
Answer:
old per: 1280
new per:2560
Step-by-step explanation:
first perimeter u get it by adding all the sides and since its a square then all the sides are equal so u can just do
320*4 which is equal to 1280
and by doubling the sides u can just double it in the old equation meaning
(320*2)*4
which is equal to 2560
Step-by-step explanation:
the difference is the previous term multiplied by 4 to get the next term
2,8,32,128,512,2048,8192

Answer:
f(x) = 4/7x + 20/7
Step-by-step explanation:
If we were to graph this function, we would see that the two points would be, (-5, 0), and (2, 4). First, we have to find the slope, which is equal to:
<u>(first y-coordinate - the second y coordinate)</u>
(first x-coordinate - second x coordinate)
= <u>(0 - 4)</u>
(-5 - 2)
= -4/-7 = 4/7. now, we multiple -5 by 4/7 and get -20/7. we have to add 20/7.
Thus, the answer is f(x) = 4/7x + 20/7
