Answer:
Step-by-step explanation:
The answer is: H equals 3 plus 0.5 D
It's this because the plant grows at 0.5 each day so that would be: 0.5xD or 0.5D and the plant is already 3 so that would make it +3. In all the height would be H = 3 + 0.5D which is indicated in words above.
Answer:
Step-by-step explanation:
y = 0.2x + 17......the slope is 0.2 (or 1/5)....in y = mx + b form, the slope can be found in the m position
(x,18).....y = 18 (25,y).....x = 25
y = 0.2x + 17 y = 0.2x + 17
18 = 0.2x + 17 y = 0.2(25) + 17
18 - 17 = 0.2x y = 5 + 17
1 = 0.2x y = 22..........(25,22)
1 / 0.2 = x
5 = x.................(5,18)
Answer:
first change 1 gallon into quarts and that will be

so 2 quarts = ? cross multiply ans the answer u will get is 9.6076
Answer:
y= -1/4x+3/4
Step-by-step explanation:
You are given (-5,2) and x=4
This means that the slope is 4
When finding perpendicular, the slope is the reverse reciprocal of the original slope. The reverse of 4 is -4. The recirprocal is the opposite of -4/1, so it is -1/4.
Slope= -1/4
The slope-intercept form is y=mx+b where you are trying to find b.
Plug in the y value in (-5,2) for y
Plug in the slope for m
Plug in the x value in (-5,2) for x
y=2
m= -1/4
x= -5
y=mx+b
2= -1/4(-5)+b <u>Plug in everything</u>
2= 5/4+b <u>Multiply -1/4 and -5</u>
3/4=b <u>Subtract 5/4 from 2 and you get b</u>
<u />
Since we have b now we can make an equation using it.
y=mx+b <u>Use the form</u>
y= -1/4x+3/4 <u>Plug in m and b</u>
