Use the elimination method to solve the system of equations. Choose the correct ordered pair.

-x + y = -2
2x - 3y = 4

A. (3, 1)
B. (4, 2)
C. (2, 0)
D. (5, 3)

Answers

Answer:

C. (2, 0)

Step-by-step explanation:

-x + y = -2

2x - 3y = 4

Multiply both sides of the first equation by 2.

Write the second equation below it and add them.

-2x + 2y = -4

(+) 2x - 3y = 4

----------------------------

-y = 0

y = 0

Start again with the original equations.

Multiply both sides of the first equation by 3. Write the second original equation below it and add them.

-3x + 3y = -6

(+) 2x - 3y = 4

-------------------------

-x = -2

x = 2

a. -5/4
b. -4
c. -1/4
d. -4/5

Answers

Answer:

d. -4/5

Step-by-step explanation:

When using the equation m = y2 - y1 / x2 - x1, we get m = 5-1 / -3-2.

Simplified: m = 4/-5.

The negative can be placed on the numerator or denominator, it doesn't make a difference.

What is the slope of a line perpendicular to the line whose equation is 12x-9y=135

Answers

Answer:

[tex]\frac{-9}{12}[/tex]

Step-by-step explanation:

First, we need to isolate y.

1. Subtract 12x from both sides.

-9y=-12x+135

2. Divide by -9 in order to isolate y.

[tex]y=\frac{12}{9} x-15[/tex]

3. Understand that perpendicular equations' slopes are opposite and reciprocal to the original equation. The slope of the original equation is [tex]\frac{12}{9}[/tex], so the reciprocal and opposite (flip and change the sign) slope would be [tex]\frac{-9}{12}[/tex].

What is a verbal expression in mathematics?

A mathematical expression when written using verbal statements is known as the verbal expression of that mathematical expression.

Given is the following mathematical expression -

f(n) = 1/2 (n-3)

The given expression is -

f(n) = 1/2 (n-3)

Now, Assume A = (n - 3) represents the the difference of n and 3.

1/2 (A) represents its one half.

Therefore, the correct verbal expression for the function f(n) = 1/2 (n-3) is → One-half the difference of n and 3.

Lauren bought 13.25 yards of yarn for $6.99. How much would it cost if she bought 24
yards of yarn?

Answers

As we know that 13.25 yards = 6.99

We can use our knowledge to figure out the price of one yard by dividing both sides by 13.25:

13.25yards = 6.99

1yard = 699/1325

Then multiply both sides by 24 to get the price for 24 yards:

24yards = 12.6611321

As we are dealing with money we will only take the first two decimal points and NOT round:

24 yards would cost $12.66

Simplify the expression: 4(x+3)+3(5−x)

x + 27

x +8

2x + 15

19x + 11

Answers

Answer:

A. x + 27

Step-by-step explanation:

4(x+3)+3(5−x)

4x + 12 + 15 - 3x

x + 27

4(x + 3) + 3(5 - x)

First multiply each of the brackets by the number on the outside:

4(x + 3) = 4x + 12

3(5 - x) = 15 - 3x

Then add these into the expression:

4x + 12 + 15 - 3x

Collect the like terms (the things that have the same letters):

4x - 3x = 1x (but remember we don’t write the 1, so it’d just be x)

12 + 15 = 27

Therefore:

x + 27

Your answer would be:

A) x + 27
