Y= f(x)= ax+b
when x= -1, y= -1
-1= -a+b | * ( -1)
when x= -3, y=2
2= -3a+b
-3a+b= 2
a - b= 1
--------------
2a=3
a=3/2 is the slope
Answer:
G and H

Answer:
A=4.
Step-by-step explanation:
Note: In the expression of area the first term should be
.
It is given that area of a rectangular floor of your house is
and the length is
units.
We know that, area of a rectangle is
Since length of the rectangle is
, therefore
is a factor of
and the value of
is 0 at x=-2.
Divide both sides by 4.
Therefore, the value of A is 4.
The car's average rate is 43.7 mph. The bicycle's average rate is 12.3 mph.
To get this solution, let the bicycle's average rate be (x) and the car's average rate be (x + 31.4) mph.
Distance= Speed x Time
364 = (x + x + 31.4) 6.5
364 = (2x + 31.4) 6.5
364/6.5 = 2x + 31.4
56 = 2x + 31.4
56 - 31.4 = 2x
24.6 = 2x
24.6/2 = x
12.3 = x
x = 12.3 mph
x+31.4 = 43.7 mph
