Question

For each equation below find y if x = 2

Answer 1

a. 7-2=5

b. 4-1=3

c. $\sqrt{2+14}= \sqrt{16}$=4

Answer 2

Hey! Hope I can help!

a. y = 7 - |$x$|, which if we fill in $x$, then we get this equation: y = 7-2, and 7-2 = 5. y = 5.

b. y = $x^{2}$ - 1, which if we fill in $x$ and multiply 2 to the power of 2, we get this equation: y = 4 - 1. 4 - 1 is 3. y = 3.

c. y = $\sqrt{x + 14}$, which if we fill in $x$ and square root 2+14 (16), we get this equation: y = 4.
