Answer:
y=0.75x+5
Step-by-step explanation:
It would be this equation because you start at 5, which is the y-intercept, then you add 0.75 for every pound of apples. So on a graph you would start at 5 on the y-line then go up by 0.75
Answer:
<em>The porch is 7.35 feet off the ground</em>
Step-by-step explanation:
<u>Trigonometric Ratios</u>
The ramp, the height of the porch, and the distance from the base of both form a right triangle where trigonometric ratios can be applied.
The angle of 20° has the height of the porch H as the opposite side, and the hypotenuse is the length of the ramp.
The sine is defined as:
For our problem:
Solving for H:
Find the sine of 20° by using a calculator:
H=7.35 feet
The porch is 7.35 feet off the ground
20 inches is how much it would grow in 5 1/2 months
Answer:
x = 20
y = 50
Step-by-step explanation:
10x + 2y = 300 | ×2 |
8x + 4y = 360 | ×1 |
20x + 4y = 600
8x + 4y = 360
_____________--
12x = 240
x = 240/12
x = 20
10x + 2y = 300
10(20) + 2y = 300
200 + 2y = 300
2y = 300 - 200
2y = 100
y = 100/2
y = 50
