Answer:
y = 3/4x+7
Step-by-step explanation:
The slope is 3/4 and a point is (-8,1)
We can use point slope to make an equation for the line
y-y1 = m(x-x1)
y-1 = 3/4(x--8)
y-1 = 3/4(x+8)
y-1 = 3/4x +6
Add 1 to each side
y-1+1 = 3/4 x+6+1
y = 3/4x+7
This is in slope intercept form (y=mx+b)
The 21 part repeats
it can be represented as 21/99
it's rational
Answer:
1.16ft tall.
Step-by-step explanation:
168/144= 1.16 ft tall
or rounded to the nearest number = 1.20 ft.
Looks like you did most of it.
The next step would be setting them equal to 105, like the problem suggests.



Then we can plug back in to find the numbers.




The three numbers are
.
Hope this helps.
頑張って!
f(x) = 20x² - 18x - 25
f(-1) = 20(-1)² - 18(-1) - 25
= 20 + 18 - 25
= 13
