Identify a pair of alternate exterior angles.
a. 6 and 8
b. 2 and 7
c. 3 and 6
d. 3 and 2

Answer:

11a + 5b

Step-by-step explanation:

3(2a + 5b) + 5(a-2b)

First, distribute 3 to 2a and 5b, and distribute 5 to a and -2b

6a + 15b + 5a - 10b

Combine like terms

11a + 5b

Answer:

n=5

Step-by-step explanation:

3/9 = 1/3

so

1/3=n/15

by cross multiplication

15×1 =n×3

15=3n

so

n=15÷3

n=5

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

When you combine like terms you see the ones that are similar then you add or subtract, depends on what the signs are. For this one -7x is similar to x so in this case you would add x to the -7x which will give you -6x.

Answer: It crosses the x-axis at 2

Step-by-step explanation:

Hope this helped!

Answer:

easy, x=2 or (2,0)

Step-by-step explanation:

Since you are solving for x, you need to make y 0. So 2x+y(0)=4, 2x+0=4, 2x=4,x=2. So there you have it. x=2 or (2,0)

x = 2

Answer:

-15/6

Step-by-step explanation:

If you look at the first number in each point, the x coordinate, you see the 2nd point is 6 forward from the 1st point. Now the 2nd number is the y coordinate, and you can see it goes down 15 from the 1st coordinate. So y/x is the slope.

Answer: -2 1/2

Step-by-step explanation:

Slope= Yb-Ya/Xb-Xa

In this case= (-8-7)/(4- -2)

This equals -15/6

Simply to -2 1/2

Answer:

2

Step-by-step explanation:

ok so let's start

were starting off with -3/4 and were adding 2 3/4 to that and it's equal to 2 3/4 subtract 3/4

-3/4 + 2 3/4 = 2 3/4 - 3/4

2 3/4 - 3/4 = 2

-3/4 + 2 3/4 = 2

it's 2 my dude or girl i don't know

Answer:

slope of perpendicular line is -1/4

Step-by-step explanation:

slope of standard equation of line that is ax+ by = c is

slope m = -a/b

given equation is

12x – 3y = 81

comparing it with ax+ by = c

a = 12

b = -3

thus

slope of given line = -12/-3 = 4

we also know product of slope of two perpendicular line is -1

let the slope of other line be m

thus,

product of given line line and perpendicular line is -1

4*m = -1

m = -1/4

Thus,

slope of perpendicular line is -1/4

Answer:

you additive inverse

Step-by-step explanation:

Answer:

Step-by-step explanation:

First you have to figure out n. Let's say it's 1, then you would multiply it by 4. That would be 4. Then subtract 32. In this case, then the answer would be - 28.

For this one, first you have to figure out w. Let's make w = 2. Then multiply is by 3 so it would be 6. Then add 66. In this case, it would be 72.

Answer:

y = 2½ = 2.5

Step-by-step explanation:

From the question given above, the following data were obtained:

Perimeter = 129

Slant Side (a) = 10y – 9

Base (b) = 17y + 6

y =.?

The perimeter of a parallelogram can be obtained by using the following formula:

Perimeter = 2(a + b)

Thus, with the above formula, we can obtain the value of y as shown below:

Perimeter = 129

Slant Side (a) = 10y – 9

Base (b) = 17y + 6

y =.?

Perimeter = 2(a + b)

Perimeter = 2a + 2b

129 = 2(10y – 9) + 2(17y + 6)

Clear bracket

129 = 20y – 18 + 34y + 12

Collect like terms

129 + 18 – 12 = 20y + 34y

135 = 54y

Divide both side by the coefficient of y i.e 54

y = 135/54

y = 2½ = 2.5

Thus, the value of y is 2½ or 2.5

Answer:

m = -36

Step-by-step explanation:

Solve for m:

m/4 - 3 = m/2 + 6

Hint: | Put the fractions in m/4 - 3 over a common denominator.

Put each term in m/4 - 3 over the common denominator 4: m/4 - 3 = m/4 - 12/4:

m/4 - 12/4 = m/2 + 6

Hint: | Combine m/4 - 12/4 into a single fraction.

m/4 - 12/4 = (m - 12)/4:

(m - 12)/4 = m/2 + 6

Hint: | Put the fractions in m/2 + 6 over a common denominator.

Put each term in m/2 + 6 over the common denominator 2: m/2 + 6 = m/2 + 12/2:

(m - 12)/4 = m/2 + 12/2

Hint: | Combine m/2 + 12/2 into a single fraction.

m/2 + 12/2 = (m + 12)/2:

(m - 12)/4 = (m + 12)/2

Hint: | Make (m - 12)/4 = (m + 12)/2 simpler by multiplying both sides by a constant.

Multiply both sides by 4:

(4 (m - 12))/4 = (4 (m + 12))/2

Hint: | Cancel common terms in the numerator and denominator of (4 (m - 12))/4.

(4 (m - 12))/4 = 4/4×(m - 12) = m - 12:

m - 12 = (4 (m + 12))/2

Hint: | In (4 (m + 12))/2, divide 4 in the numerator by 2 in the denominator.

4/2 = (2×2)/2 = 2:

m - 12 = 2 (m + 12)

Hint: | Write the linear polynomial on the left hand side in standard form.

Expand out terms of the right hand side:

m - 12 = 2 m + 24

Hint: | Move terms with m to the left hand side.

Subtract 2 m from both sides:

(m - 2 m) - 12 = (2 m - 2 m) + 24

Hint: | Combine like terms in m - 2 m.

m - 2 m = -m:

-m - 12 = (2 m - 2 m) + 24

Hint: | Look for the difference of two identical terms.

2 m - 2 m = 0:

-m - 12 = 24

Hint: | Isolate terms with m to the left hand side.

Add 12 to both sides:

(12 - 12) - m = 12 + 24

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

-m = 24 + 12

Hint: | Evaluate 24 + 12.

24 + 12 = 36:

-m = 36

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of -m = 36 by -1:

(-m)/(-1) = -36

Hint: | Any nonzero number divided by itself is one.

(-1)/(-1) = 1:

Answer: m = -36
