Answer:
x= 0
Step-by-step explanation:
Here in this question, we are given a linear equation of single variable x, and we have to solve the equation for x.
The given equation is 9x -7= -7 ....... (1)
Now, taking all the constant terms to the right side of the equation and all the x terms to the left side of the equation.
Hence, the equation becomes
9x = -7 +7
⇒ 9x =0 {Since, -7 and 7 cancels each other}
⇒ x= 0/9= 0 (Answer) {Since zero divided by any number is equal to zero}
Alex has $14, Barry has $12 and Carl has $9
Answer:
78.5
Step-by-step explanation:
The diameter (d) is equal to the radius x 2, so take half of d to get r. Use r (5) in the equation to get your answer.
A= 3.12 x 5^2
A= 78.5
Answer:
y = 1.5x + 4
Step-by-step explanation:
Slope = (y2-y2)/(x2-x1)
= (1-4)/(-2-0) = -3/-2 = 3/2
y = (3/2)x + c
When x=0, y=4 (y-intercept is 4)
y = (3/2)x + 4
y = 1.5x + 4
Answer:
An equation for the absolute value that represents the midpoint of 10 and 15 would be (10 + 15)/2 = 12.5
