You can sum like terms. Two terms can be summed if they are both constants (i.e. pure numbers) or if they involve the same powers of the same variable.

In this case, 3x and 13x can be summed because they both involve 'x' alone. The sum is

$3x+13x = (3+13)x = 16x$

As for the other two terms, you simply have to sum two numbers, as usual:

$-9-6 = -15$

So, the final answer is

$16x-15$

Lynna [10]

First we need to find how many meters she did on Saturday a hour to add 200 meters per hour faster on Sunday. 2400/1.5 = 1600
1600 meters per hour + 200 meters per hours = 1800 meters per hours on sunday

B. 1800 meters per hours

Solve 2x+8<10 or 2x+8>20

galben [10]

Answer:

1 Add 88 to both sides.

2x=10+8

2 Simplify 10+810+8 to 1818.

2x=18

3 Divide both sides by 22.

x=\frac{18}{2}

4 Simplify \frac{18}{2}

to 99.

x=9

Step-by-step explanation:

2x−8=10

1 Let x=9x=9.

2\times 9-8=10

2×9−8=10

2 Simplify 2\times 92×9 to 1818.

18-8=10

18−8=10

3 Simplify 18-818−8 to 1010.

10=10

Write an algebraic expression to represent the new x-coordinate after a reflection across the x-axis given any initial x-coordin

denpristay [2]

Answer:

$x' = x$

Step-by-step explanation:

Given

$Initial\ Coordinate = x$

Required

Find the new coordinate of x when reflected over x axis

Represent the new x value as x'

When a function is reflected over the x axis, the x value remains unchanged;

So, we have:

$x' = Initial\ Coordinate$

$x' = x$
