Answer 1

Answer: Take two points to find the slope
Let;s take (1, -3) and (-3, -1)

Point slope formula is

m = $(y2-y1)/(x2-x1)$
or
y₂-y₁ = m×(x₂-x₁) Which is the same thing

m = $(-1-(-3))/(-3-1)$
= $(2)/(-4)$
It can be simplified:
= $-(1)/(2)$
Now we found the slope

Same formula:
y₂-y₁ = m × (x₂-x₁)
Substitute the point only (1, -3)
y₂-(-3) = $-(1)/(2)$ × (x₂-1)
y₂ + 3 = $-(1)/(2)$ × (x₂ - 1) (minus minus = plus)

The last option is the answer

Answers

First use distribution properties and times everything in the brackets by the number before it
So
7x-14= 3x+ 12
Then subtract the x value from one side and move it to the other
Example
7x-14=3x+12
-3x. -3x
Therefore you’d have
4x-14=12
then move your negative 14
4x-14=12
+14 +14
4x=26
Divide both sides by 4
X=6.5

Answer:

x=6.5

Step-by-step explanation:

7(x-2)=3(x+4)

Step 1. Distribute

7x-14=3x+12

Step 2. Combine like terms and calculate

4x=12+14

Step 3. Divide 4 on both sides

4x=26

Solution:

x=6.5

The perimeter of a parallelogram is 46in. If the length of one side is 14in., what is the length of a side adjacent to it?

Answers

Adjacent means connected to so you are looking for the width.

Perimeter = 2(length) + 2(width)
P = 2l + 2w

46 = 2l + 2w
l = 14

46 = 2(14) + 2w
46 = 28 + 2w
18 = 2w
9 = w

Width: 9 inches

What two numbers multiply to __ and add up to __?1. Multiply -15 add -2
2. Multiply -32 add -4
3.multiply -14 add -5
4. Multiply -24 add 5

Answers

Arrange the factors of the product so that when added you get the sum:
1. The factors of 15 are 3 and 5 or 1 and 15. You are looking for the pair that is two apart, which are 3 and 5. Because they add up to be negative 2, 5 must be negative, so the two numbers you get are 3 and -5. The rest can be solved similarly:
2. (Out of 1 and 32, 2 and 16, and 4 and 8, only 4 and 8 works) -8+4=-4, -8*4=-32
3. (Out of 1 and 14, and 2 and 7, only 2 and 7 works) -7+2=-5, -7*2=-14
4. (Out of 1 and 24, 2 and 12, 3 and 8, and 4 and 6, only 3 and 8 works) -3+8=5, -3*8=-24.

Answer:

-3 + 8 = 5, -3 · 8 = -24
