Answer:
c
Step-by-step explanation:
To solve the equation we just substitute x with 7
so
5(7+3)
5*10
50
so the answer is c

Answer:
m = -1 (answer (a))
Step-by-step explanation:
Recall that the slope of a straight line is m = rise / run.
As we go from the point (0, -2) to the point (2, -4), we see an increase of 2 in x and a decrease of 2 in y.
Thus, the slope of this line is m = rise / run = 2/(-2), or m = -1 (answer (a))
D— put 7 over 1 and then change division sign to multiplication & then flip 9/5 to 5/9
Answer:
C
Step-by-step explanation:
You need to isolate the y variable. The first thing you need to do is move the 2 and 3x to the other side of the equation.
3x + 1/5y - 2 = 0
1/5y = -3x +2
Then you need to get rid of the 1/5 so you multiply both sides equation by the reciprocal of 1/5 which is 5/1 or 5.
y = ( -3x +2) 5
then you distribute the 5 to get
y = -15x+10
One solution is the y intercept (0,1/2)
