42 is increased to 63 what is the percent increase? super easy and urgent!

50%

Step-by-step explanation:

Percent change = [(63 - 42) / |42|] x 100 = [(21) / 42] x 100 = 50 % (increase)

Where: 42 is the old value and 63 is the new value. In this case we have a positive change (increase) of 50 percent because the new value is greater than the old value.

PLEASE GIVE BRAINLIEST

Step-by-step explanation:

63 - 42 = 21

to find percent increase divide 21 by 42

21 / 42 = .5 or 50% increase

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.

mark brainliest!

i agree because i see the other persons thinking is clear
