B. (-7, 3), (1, 2), (5, 3), (-7, 2)

Since

x = − 7 produces y = 3 and y = 2

So the relation is not a function.

Barack walks 2 kilometers south and then x kilometers east. He ends 5 kilometers away from his starting position. Find x

amid [387]

Answer:

4.6 km

Step-by-step explanation:

-This is a Pythagorean Theorem problem where the distances walked are effectively the base and height of the imaginary right triangle thereof.

#Apply Pythagorean theorem to solve:

$b^2+h^2=H^2\\\\2^2+x^2=5^2\\\\x^2=5^2-2^2=21\\\\x=\sqrt{21}\\\\x=4.58\ km$

$\approx 4.6\ km$

Hence, the distance x is 4.6 km

View the lane below and calculate the slope<br> by using the slope formula

velikii [3]

Answer:

slope = 4

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 12) ← 2 points on the line

m = $\frac{12-0}{3-0}$ = $\frac{12}{3}$ = 4
