Explain how solving $2x<-8$ is different from solving $-2x<8$ .

Mathematics
1 answer:
miv72 [106K]2 years ago
6 0

Answer:

When we divide by a negative value, the sign for the inequality changes.

Step-by-step explanation:

2x < -8, to solve we would divide by 2 and receive x < -4. However, in solving -2x < 8, we would divide by negative 2, which would result in x > -4. Clearly, these sequences provide opposite answers and that is a rule to inequalities, that when dividing by a negative number, we must flip the less than/greater than sign.

Lorna has 60$ and her sister has 120$ Lorna saves 7$ Per week and solution represent the number of weeks w it will take for girl
Dominik [7]
Let x be the amount of weeks.

60 + 7x = 120
60 - 60 + 7x = 120 - 60
7/7x = 60/7
x = 8.571428571

What is the remainder when the polynomial f(x)=3x^3-4x^2+2x+8 is divided by (x-5)
allsm [11]

Answer:

remainder = 290

Step-by-step explanation:

\frac{3x^3-4x^2+2x+8}{x-5}

= 3x² + 11x + 57 + \frac{290}{x-5}

quotient = 3x² + 11x + 57 and remainder = 290
