Hi,
2.
5(3+2x) = 10x - 4
15 + 10x = 10x - 4
10x - 10x = - 4 - 15
0 = -19
In other word there is no solution here, code G
3.
x+5 = (3x+13) / 2
x+5 = (3/2)x + 13/2
x - (3/2)x = 13/2 - 5
x(1-3/2) = 13/2 - 10/2
x(2/2 - 3/2) = 3/2
(-1/2)x = 3/2
x = (3/2) / (-1/2)
x = (3/2) * (-2)
x = (-6/2)
x= -3
code : D
Good Luck :)
Answer:
22
Step-by-step explanation:
diameter = radius x 2
11 x 2 = 22
(2,60)(4,120)
slope = (120 - 60) / (4 - 2) = 60/2 = 30 <===
Answer:
The answer to your question is 2 or (2, 0)
Step-by-step explanation:
Data
slope = m = 4
y-intercept = -8
Process
1.- Write the equation of the line in the slope y-intercept
y = mx + b
In this equation:
m = slope
b = y-intercept
-Substitution
y = 4x - 8
2.- To find the x-intercept, consider that y = 0 and solve for x.
0 = 4x - 8
4x = 8
x = 8/4
x = 2 or (2, 0)
