svetoff [14.1K]

Answer:

your answer is 1!

The gcf of 7 and 9 is the largest positive integer that divides the numbers 7 and 9 without a remainder. Spelled out, it is the greatest common factor of 7 and 9. Here you can find the gcf of 7 and 9, along with a total of three methods for computing it. In addition, we have a calculator you should check out. Not only can it determine the gcf of 7 and 9, but also that of three or more integers including seven and nine for example. Keep reading to learn everything about the gcf (7,9) and the terms related to it.

What is the GCF of 7 and 9

If you just want to know what is the greatest common factor of 7 and 9, it is 1. Usually, this is written as

gcf(7,9) = 1

The factors of 9 are 9, 3, 1.

The factors of 7 are 7, 1.

The common factors of 9 and 7 are 1, intersecting the two sets above.

In the intersection factors of 9 ∩ factors of 7 the greatest element is 1.

Therefore, the greatest common factor of 9 and 7 is 1.

Solve for x: |2x+6| -4 = 20

Bingel [31]

|2x + 6| - 4 = 20

First, add 4 to both sides. / Your problem should look like: |2x + 6| = 20 + 4
Second, simplify 20 + 4 to 24. / Your problem should look like: |2x + 6| = 24
Third, break down the problem into these 2 equations. / 2x + 6 = 24 and -(2x + 6) = 24
Fourth, solve the 1st equation: 2x + 6 = 24
Subtract 6 from both sides. / Your problem should look like: 2x = 24 - 6
Simplify 24 - 6 to 18. / Your problem should look like: 2x = 18
Divide both sides by 2. / Your problem should look like: x = $\frac{18}{2}$
Simplify $\frac{18}{2}$ to 9 / Your problem should look like: x = 9
Fifth, solve the 2nd equation: -(2x + 6) = 24
Simplify brackets. / Your problem should look like: -2x - 6 = 24
Add 6 to both sides. / Your problem should look like: -2x = 24 + 6
Simplify 24 + 6 to 30. / Your problem should look like: -2x = 30
Divide both sides by -2. / Your problem should look like: x = $\frac{30}{-2}$
Simplify $\frac{30}{-2}$ to $- \frac{30}{2}$ / Your problem should look like: x = $-\frac{30}{2}$
Simplify $\frac{30}{2}$ to 15. / Your problem should look like: x = -15
Sixth, collect all of your solutions. / Your problem should look like: x = -15, 9

Answer: x = -15, 9 (C)

Slope=-7, through (-5,9)

Gre4nikov [31]

Answer:

y = - 7x - 26

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 7, thus

y = - 7x + c ← is the partial equation of the line

To find c substitute (- 5, 9) into the partial equation

9 = 35 + c ⇒ c = 9 - 35 = - 26

y = - 7x - 26 ← equation of line
