Answer:
4x-3y+20
Step-by-step explanation:
x=6.875
y=2.5
2x+y=30
x=12.5
y=-5
He has 288 pictures, with 38% of them containing his family. Using 288 times 0.38, this is 109.44. Assuming that pictures usually aren't a fraction of a whole picture, we must drop the decimal, which would now be 109. So, 109 of his photos are of his family
Answer:
a) it takes 4 seconds for the ball to hit the ground
b) 480 ft
c) 64 ft
Step-by-step explanation:
The parametric equation is
x(t) = 120t and y = 64t - 16t²
a) To find when the ball hits the ground, we use the y equation. The ball hits the ground at y = 0. Therefore:
t = 4 seconds,
Therefore, it takes 4 seconds for the ball to hit the ground
b) Since it takes 4 seconds for the ball to hit the ground, to find how far the ball would travel, we substitute t = 4 into x = 120t. Therefore:
x = 120(4) = 480
x = 480 ft
a) The maximum height of the ball is the vertex of the y equation.
The vertex occurs at t =
Substituting t = 2 in the y equation:
y = 64(2) - 16(2)² = 128 - 64 = 64 ft
y = 64 ft
Y= 2x + 2 , the y intercept is 2, the graph was provide this point for u already . E Then , I just found the slope by using the formula that I had learned from textbook , which is M= y2 - Y1 divided by X2-X1 .
