pychu [463]

Answer:

14x-10y=-96

Step-by-step explanation:

we know that

The equation of the line in standard form is equal to

Ax+By=C

where

A is a positive integer

B and C are integers

we have

y=1.4x+9.6

Multiply by 10 both sides

10y=14x+96

isolate the variable x and y (Remember that A must be positive)

14x-10y=-96 -----> standard form

Art [367]

Answer:

$17 \le t \le 28$

Step-by-step explanation:

Given

$t = 22\frac{1}{2}$ --- average time

$\triangle t = 5\frac{1}{2}$ --- the variation

Required

The inequality to represent the scenario

To do this, we simply add and subtract the variation from the average time.

i.e.

$t \± \triangle t$

So, the inequality is:

$22\frac{1}{2} - 5\frac{1}{2} \le t \le 22\frac{1}{2} + 5\frac{1}{2}$

Solve:

$17 \le t \le 28$
