Answer:
2/5
Step-by-step explanation:
Let x = numerator
3 + x = denominator
the numerator and denominator are increased by 1 , the fraction becomes
cross multiply
2(x + 1 ) = 4 + x
2x + 2 = 4 + x
combine like terms
2x - x = 4 - 2
x = 2 = numerator
denominator = 2 + 3 = 5
2/5 fraction
Shape A is congruent to Shape B because If you were to rotate one of the two and flip it the would like up and match.

Step-by-step explanation:
<u>Step 1: Define</u>
g(x) = 5x + 4
g(x) = 9
<u>Step 2: Solve for </u><u><em>x</em></u>
- Substitute in function value: 9 = 5x + 4
- [Subtraction Property of Equality] Subtract 4 on both sides: 5 = 5x
- [Division Property of Equality] Divide 5 on both sides: 1 = x
- Rewrite: x = 1
∴ when the function g(x) equals 9, the value of <em>x</em> that makes the function true would be <em>x</em> = 1.
