What is the solution to the inequality -4x < 8? x < -24 x > -24 x < -2 x > -2

liberstina [14]

Answer:

x > -2

Step-by-step explanation:

Solve the inequality -4x < 8 using inverse operations. If you divide or multiply by a negative, flip the inequality sign.

$-4x < 8\\\\\frac{-4x}{-4} < \frac{8}{-4}$

x > -2

Solve for x:<br><br> mx + nx = p

algol13

Thanks for the question!

mx + nx = p
Group them with x as the GCF
x(m +n) = p
Divide both sides by m+n
x = p/m+n

Hope this helps!

the value of y is directly proportional to the value of x. if y=35 when x=140,what is the value of y when x=70

Goryan [66]

Y = kx, where k is the constant of proportionality.

We need to find k as our first step.

35 = k140

35/140 = k

1/4 = k

We can now find y when x = 70.

y = kx

y = (1/4)(70)

y = 70/4

This fraction can be simplified or reduced more.

The number 2 is the GCF of 70 and 4.

70 ÷ 2 = 35

4 ÷ 2 = 2

Answer:

y = 35/2
