D you put in 5 in place of where the n is
First, move like terms on one side. Next, add them and divide. See the attachment for solution.
Answer:
a = 8.
Step-by-step explanation:
a/4 + 8 = 10 where x is the number to find.
a/ 4 = 10-8 = 2
a = 4*2
a = 8.
Answer:
Line is y = -3x + 3
Slope = -3
y-intercept = 3
Step-by-step explanation:
Slope is the movement up or down, and left or right. Y-intercept is the point in which the line crosses the y-axis. In slope-intercept form (y=mx+b), m represents the slope, while b represents the y-intercept.
So since the line crosses the y-axis at positive 3, that will be the y-intercept. Now if we go from that very same point, and do rise/run, we'd move downwards 3 units and to the right 1 unit, to get our slope of -3/1 (it's written as just -3 though).
So now we plug it in: y = -3x + 3
Hope this helps you :)
The answer can be found by replacing x with 1 in 1 - x. Therefore f(1) equals 0
Hope that helps you
