Answer:
Step-by-step explanation:
If you are confused as to how the answer is 9 then all we have to do is solve for c
c + 11 = 20
So in order to solve this you have to subtract 11 from 20 to get c alone on one side so...
c = (20-11)
c = 9
Answer:
Step-by-step explanation:
20.70/90= 0.23 per foot
30*.23= 6.90
It'll cost $6.90 for 30 more feet.
Answer:
y = 1/2x + 3
Step-by-step explanation:
The slope of a parallel line is the same as the original.
Find the new y-intercept.
y = 1/2x + b
2 = 1/2(-2) + b
2 = -1 + b
3 = b
y = 1/2x + 3
Best of Luck!
Answer:
y = -x + 17
Step-by-step explanation:
A(-10,-3)
B(7,14)
C(5,12)
Need line CD perpendicular to AB through C.
Solution:
slope of AB, m1 = (yb-ya) / (xb-xa) = (14- -3) / (7- -10) = 17/17 = 1
Slope of CD, m2 = -1/m1 = -1 / 1 = -1
Line CD through C, using the point slope form
y-yc = m2(x-xc)
y-12 = -1 (x-5)
rearrange
y = -x + 5 + 12
y = -x + 17
