Explanation:
4x+8=32
Isolate for x. Start by subtracting 8 from both sides of the equation.
4x+8−8=32−8
4x=24
Divide both sides of the equation by 4.
4x4=244
x=6
Answer:
is equation of BC
Step-by-step explanation:
Given that AB and BC form a right angled triangle at point B.
i.e. BC is perpendicular to AB
Line AB contains two points (-3,-1) and (4,4)
Slope of AB =
Slope of BC would be -1/slope of AB since AB and BC are perpendicular
Slope of BC =\frac{-7}{5}
Also we got a point on BC as B.
Use point slope formula
We first notice that the sequence of numbers:
12, 21, 30, 39, 48 increases by 9 ($ per day).
We see that these values, related to the days 0, 1, 2, 3, 4 can be written as follows:
12=0*9+12
21=1*9+12
30=2*9+12
39=3*9+12
48=4*9+12
Thus, the price to pay for renting a lawn mower x days is y=9x+12.
Answer: y=9x+12
X = -6.4
First, you would subtract 8 on both sides:
-2.5x + 8 - 8 = 24 - 8
The 8 cancels out on the left side of the equation, and 24 - 8 = 16
Next, divide both sides by -2.5, to get rid of the number that is multiplying by x.
-2.5x/-2.5 = 16/-2.5
= x = -6.4
*Remeber, when dividing a negative by a positive, the answer is negative. In this case, 6.4 is negative.
