The expressions are simplified and factored in as below.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The expressions are simplified as,
1.
5x + 3x
= 8x
2.
2x + x
= 3x
3.
6x + 8x
= 14x
4.
9x + 3x
= 12x
5.
7x + 4x
= 11x
6.
10x + x
= 11x
7.
3x + 2 + 4x
= 7x + 2
8.
15x + 3 + x
= 16x + 3
9.
2x + 5 + 6x
= 8x + 5
10.
7x + 2x + 4
= 9x + 42
11.
18x + 3x + 9
= 21x + 9
12.
6x + x + 8
= 7x + 8
13.
21x + 15y
= 3(7x + 5y)
14.
2x + 14y
= 2(x + 7y)
15.
15x + 10y
= 5(3x + 2y)
16.
12x + 18y
= 6(2x + 3y)
17.
10x + 30y
= 10(x + 3y)

= 2(3x + 7y)
19.
8x + 16y
= 8(x + 2y)
20.
45x + 27y

4) Line L has equation y = 4x - 7, and line M is parallel to line L and passes through the point (2,15). Determine the equation of line M. A) y = 4x + 7 B) y = 2x + 7 ©). y = 4x + 15 D) y = 2x + 15
Answers
Answer:
the answer is A.y=4x+7
Step-by-step explanation:
Line M is parallel to the line L, so the equation for line M isy=4x+b
Plug in the coordinates of the point (2,15) , you get:
15=4*2+b
Solve that to get b=7
Therefore the equation of line M is y=4x+7

Please find the slope of (-2, 4) and (3, -5)
Answers
Answer:
The slope of the line = m = -9/5
Step-by-step explanation:
Given the points
(-2, 4)(3, -5)Determining the slope between (-2, 4) and (3, -5)
(x₁, y₁) = (-2, 4)
(x₂, y₂) = (3, -5)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-5 - 4] / [3 - (-2)]
= [-9] / [3 + 2]
= -9/5
Thus, the slope of the line = m = -9/5
Answer:
m = -9/5
Step-by-step explanation:
Taking (-2,4) as (x1,y1), and
Taking (3,-5) as (x2,y2)
Using the slope (m) formula:
[tex]m = \frac{y2-y1}{x2-x1}[/tex]
= (-5-4)/(3-(-2))
= -9/(3+2)
= -9/5
Hence, the slope is -9/5
