Answer:

See below.

Step-by-step explanation:

x-7≤3x+1

 +7     +7

x≤3x+8

-3x -3x

-2x≤8

/-2   /-2

x≥-4

The inequality symbol reverses when divided/multiplied by a negative term.

Answer:

x ≥ -4

Step-by-step explanation:

we can solve inequalities in the same way as equations except when multiplying or dividing by a negative; in which case you must reverse the inequality symbol

x - 7 ≤ 3x + 1

we can begin by adding 7 to each side to get:

x ≤ 3x + 8

now subtract 3x from each side to get:

-2x ≤ 8

we have to divide each side by -2 so we must reverse the symbol:

x ≥ -4

(a) Write 14 as a decimal.​
Yuliya22 [10]

Answer:

0.14

Step-by-step explanation:

14% describes 14 out of 100. It is written as 14 in the numerator and 100 in the denominator of a fraction. A percent is always written as the number over 100 as a fraction. “Out of 100” refers to the decimal place “hundredths.” 14% is 14 hundredths.

Write a slope intercept equation for a line that passes through (-2,5) and (2,-7)
wlad13 [49]

Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

First, find slope using the given coordinates. Formula for slope: y₁ - y₂ / x₁ - x₂.

Our coordinates are (-2, 5) and (2, -7). Plug them in and simplify.

5 - (-7) / -2 - 2

5 + 7 / -4

12/-4

-3

The slope is -3. The equation becomes y = -3x + b.

To find b, plug an (x, y) coordinate on the line in for x and y in the equation and solve. I'll use (-2, 5)

y = -3x + b

5 = -3(-2) + b

5 = 6 + b

-1 = b

The y-intercept is (0, -1). The equation can now be completed!

<h3>Answer:</h3>

y = -3x - 1
