Number = 42
50% of 42
= 50/100 × 42
= 21
Increased number = 42 + 21 = 63
the answer is you have to mutiply
Answer:
C
Step-by-step explanation:
In order to be a function, all of the graphs need to pass the vertical line test
Vertical line test- Only one point per vertical line, if there are more than one, it is not a function
C is the only one that has more than one point at a vertical line
Answer:
The equation of this line is y = 3x - 2
Step-by-step explanation:
In order to find this, start by finding two points on the line. We'll use (0,-2) and (1, 1). From there we start by finding the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (1 - -2)/(1 - 0)
m = (1 + 2)/(1)
m = 3/1
m = 3
Now using that, we can plug it, along with a point into point-slope form to get the answer.
y - y1 = m(x - x1)
y - 1 = 3(x - 1)
y - 1 = 3x - 3
y = 3x - 2
