Answer:

Step-by-step explanation:

So x^2 means multiplyinng x by x.

x here is 5 so:

5 * 5= 25

Then 25 - 5 is 20.

Then x - 1

5 - 1 = 4

Thereafter 20 / 4 gives you 5.

5 is your final answer.

HOPE THIS HELPED

Rewrite the expression so that the GCF is factored completely: 2x^3y+18xy-10x^2y-90y

Agata [3.3K]

2x^3y+18xy-10x^2y-90y

= 2xy(x^2 + 9)- 10y(x^2 + 9)

= (x^2 + 9)(2xy - 10y)

= (x^2 + 9) 2y(x - 5)

= 2y (x^2 + 9) (x - 5)

What is the solution set of these system5x-2y=17 and 4x-7=13?

MatroZZZ [7]

Answer:

x=5

y=4

Step-by-step explanation:

Step 1:

Let us solve for x using the $4x-7=13$ equation by isolating terms containing the variable:

$4x-7=13\\4x=20\\\fbox{x=5}$

Great! x is 5... let's find y.

Step 2:

Since we know the value of x, we can use what we know to find y using the other equation:

$5x-2y=17\\$

Given that x=5, we can replace x with 5.

$5*5-2y=17\\25-2y=17\\2y=8\\\\\fbox{y=4}$

I hope this helps! Let me know if you have any questions :)

Solve the following inequalities 7 x minus 5 / 8 x + 3 >4

olchik [2.2K]

Answer:

$x> \frac{8}{51}$

Step-by-step explanation:

$7x - \frac{5}{8} x + 3>4$

Bring constants to one side, simplify:

$\frac{51}{8} x>4 - 3 \\ \frac{51}{8} x>1 \\ x>1 \div \frac{51}{8} \\ x>1 \times \frac{8}{51} \\ x> \frac{8}{51}$

*Note that the inequality sign only changes when you divide the whole inequality by a negative number.
