Use the table to write a linear function that relates y to x.
blsea [12.9K]

Answer:

y = - \frac{2}{3} x

Step-by-step explanation:

the equation of a linear function in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

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

with (x₁, y₁ ) = (- 8, 2) and (x₂, y₂ ) = (1, - 4) ← 2 ordered pairs from the table

m = \frac{-4-2}{1-(-8)} = \frac{-6}{1+8} = \frac{-6}{9} = - \frac{2}{3}

the ordered pair (0, 0 ) indicates the line crosses through the origin, then

c = 0

y = - \frac{2}{3} x + 0 , that is

y = - \frac{2}{3} x ← equation of linear function

A tree is 117 inches tall. How tall is it in feet and inches?<br> ?
xz_007 [3.2K]

Answer:

9 ft and 9 inches

Step-by-step explanation:

there are 12 inches in a foot

1ft = 12in

2ft = 24 in

3ft = 36 in

4ft = 48

and so on

9 ft = 108 inches which is the closes to 117.

So we have 9 ft

subtract 117 from 108, which is 9 inches left over

An inequality can be formed by simply translating the problem statement to numerical expressions.

From the problem we know that 3w added with 52 hours should be equal or greater than 90 (helpful insight from the keyword "at least"). Therefore, it's inequality would look like:

3w+52>=90 (>= is used instead of ≥ for constraints in formatting)

The inequality above best models the situation.
