Answer:
-6.3
Step-by-step explanation:
4.2x, if x = 0, then y = -6.3
Answer:
17
Step-by-step explanation:
2x - 7 = 27
2x = 34
x = 17
Answer:
C = n + 2
Step-by-step explanation:
Well looking at the line on the graph we can see that the y intercept is 2 because the y intercept is the point in the line that touches the y axis.
And the slope is how fat away each points are from each other on a line so we can find the slope by using two points on the line, we can use (1,3) and (2,4).
So we set up the formula like this
.
And now we gotta plug in the numbers and solve so the answer is 4-3 = 1 and 2-1 = 1 so the slope is 1.
And we can’t write that as just n.
So the answer is C = n + 2.
For proof look at the image below.
Letter A is the answer because
4y = 15 - 3x
so y = 15/4 -3x/4
7-12 is like a negative number so it will be -5. And 13-18 would be -5 also.
