3x-7>8 and -3x ≥-36 solve the inequality
tamaranim1 [39]

Good evening,

Answer:

x > 5

x ≤ 12

Step-by-step explanation:

Visualize as if the inequality symbols are equal signs and then solve it as you would for a normal equation, note if you divide by two negative numbers at all you then switch the sign.

On a number line, an inequality sign without the “equal to” is plotted with an open circe.

An inequality sign, with the “equal to” is plotted with a closed circle.

3x - 7> 8

Add seven on both sides, we do this because we want to eliminate the 7 from one side.

3x > 15

Divide both sides by 3, we do this because you want to get rid of the 3 from x.

x > 5

As for the second inequality.

Divide both sides by -3, as I mentioned earlier switch the side since we are dividing by two negative numbers.

x ≤ 12

For the greater than inequality x > 5, plot a open circle on 5 and draw the line going to the right.

For the less than or equal to inequality x ≤ 12, plot a closed cirlce on 12 and draw the line going to the left.

A unique trick is to graph the line based on the direction (right or left) the inequality symbol is pointing to.

Find the product of (x² - 5)² using identities​
timama [110]

Answer:

Step-by-step explanation:

by idetity : (a - b)²= a² +b² -2ab

for : (x² - 5)² you have  a = x²  and b = 5

(x² - 5)²= (x²)²+5² - 2(5)(x²)

(x² - 5)²= x^4+25 -10x²
