Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
m(x) = 2(x + 4)² - 8 ← is in vertex form
with vertex = (- 4, - 8 ) → A
Answer:
width of a river = 45m
Step-by-step explanation:
ration and proportion
let x = width of a river
x 20.9 m
------ = --------
56 m 26 m
x = (20.9 * 56) / 26
x = 45 m
therefore the width of a river is 45 m
Answer: 108 cubic inches
Step-by-step explanation:
Hi, to answer this question we have to apple the next formula:
Volume of a rectangular prism (V): base area x height (deep of the soil)
Replacing with the values given:
V = 36 x 3 =108 cubic inches
Ian should put 108 cubic inches of soil in the flower pot.
The volume of the soil is 108 cubic inches.
Feel free to ask for more if needed or if you did not understand something.
I’m not very good at explaining but if we explain from the beginning the equation is y=m(x)+b and m means the slope while b means y- intercept so all you have to do is substitute these variables with the numbers in the problem basically it would be y=10x+10 also the picture attached is how you graph it. Hope this helped:)
