Answer:
it's 16
Step-by-step explanation:
82=5x+2
Minus 2 from both sides
80=5x
Divide by 5 on both sides
16=x
Answer:
n = 3
Step-by-step explanation:
2n+5-6 = 5 ( add 6 on both sides)
2n+5=11 (then subtract 5 on both sides)
2n=6 (Then divide by 2 on both sides)
<em>n = 3</em>
Answer:
C. Graph the first equation, which has slope = −2 and y-intercept = 3, graph the second equation, which has slope = −4 and y-intercept = −1, and find the point of intersection of the two lines.
Step-by-step explanation:
The two equations are in slope intercept form which is y = mx + b where m is the slope and b is the y-intercept.
In the first equation (y = -2x + 3), -2 is the slope since it is the coefficient. "b" is 3 since it is the constant of the equation.
In the second equation (y = -4x -1), -4 is the slope is the coefficient, and the y-intercept is -1 since it is the constant.
To solve the equations graphically, graph them and find the point where they intersect.
