Equations and inequalities

Inequalities and equations use similar steps to solve, but inequalities give a range of numbers that can represent the variable while an equation will give a direct answer.

Example:

4+5x=24

First you would subtract 4 or add the opposite of 4 from 24.

4+5x=24
+(-4) +(-4)
—————
5x=20

Then divide each side by 5 or multiply each side by the reciprocal of 5 to isolate the variable.

1/5*5x=20*1/5 (reciprocal)
X= 4

You would use the same steps in an inequality but end up with a different sign.

Answer with explanation
Savatey [412]

Answer: a and d

Step-by-step explanation:

(to find all points of discontinuity, set denominator equal to zero and solve)

x^2-7x+10=0\\\\

(to factor, find two numbers when added together equal -7 and when multiplied together equal 10)

-2 + -5 = -7

-2(-5) = 10

-2 and -5 are the two numbers

(x-2)(x-5)=0\\\\x-2=0\\x=2\\\\x-5=0\\x=5\\\\x=2,5

WARRIOR [948]

Answer:

- \frac{7}{4}

Step-by-step explanation:

Given

- \frac{7}{10} ÷ \frac{2}{5}

Leave the first fraction

Change division to multiplication

Turn the second fraction upside down

= - \frac{7}{10} × \frac{5}{2} ← cancel 5 and 10 by 5

= - \frac{7}{2} × \frac{1}{2}

= - \frac{7(1)}{2(2)}
