When jose took the test over, he increased his score by 15 percentage points. jose raised his score to an 83% on the test. which of the following equations represents the word problem if "x" represents jose’s score on the first test?
1. x-15=83
2. x+15=83
3. x=15+83

x + 15 = 83

Step-by-step explanation:

Since Jose raised his score b y15 percent it would be x + 15 not anything else.

x + 15 = 83

Step-by-step explanation:

x-15=83 shows that his first test score without the 15 points is 83, which isn't true because it says he raised it by 15 in the statement

x=15+83 shows that his first test score was 15 + 83, obviously not true because his test score was 83 - 15

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
