Help! What’s the y intercept of the linear equation 7+y=4.3x

Rasek [7]

Answer:

(0,-7)

Step-by-step explanation:

the y-intercept is found when the x-value is equal to 0. In this case, we are finding a coordinate pair. First, plug in 0 for x.

7+y=4.3(0)

simplify

7+y=0

subtract 7 from both sides

y=-7

Make it an ordered pair,

(0,-7)

PLZZZZ HELPPPPPP THIS IS TIMEDDDD!!!! *look at picture*

Kazeer [188]

Answer:

Height of the building = 50.8 ft

Step-by-step explanation:

A person and a building are casting the shadows at the same time of the day.

Triangles formed by the person and his shadow and the building and its shadow will be similar.

Therefore, corresponding sides of the similar triangles will be proportional.

$\frac{x}{28}=\frac{5.8}{3.2}$

x = $\frac{5.8\times 28}{3.2}$

x = 50.75

x ≈ 50.8 ft

Step-by-step explanation:

5 1/4 per 20 min (1/3 of an hour)

5.25 (5 1/4) * 3 = 15.75 pounds per hour

$0.75 earned per pound

So, 15.75 * $0.75 = $11.81
