I need help please and thank you

a =5.3

Step-by-step explanation:

The Pythagorean theorem is

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

a^2 + 6^2 = 8^2

a^2 +36 = 64

Subtract 36 from each side

a^2 +36-36 = 64-36

a^2 =28

Take the square root of each side

sqrt(a^2) = sqrt(28)

a = 5.291502622

To the nearest tenth

a =5.3

We can solve for “a” using the Pythagorean theorem.

Pythagorean Theorem: a² + b² = c²

a² + 6² = 8²

a² + 36 = 64

a² + 36 – 36 = 64 – 36

a² = 28

√a² = √28

a = 5.29150

Round to the nearest tenth.

5.29150 -> 5.3

Hence, “a” equals approximately 5.3

Best of Luck!

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
