Lubov Fominskaja [6]3 years ago

Answer:

a) -6

b) 3

c) Y = -6x + 3

Step-by-step explanation:

Pick two points and find rise/run = slope

rise y1 - y2 = 9 - 3 = 6

run x1 - x2 = -1 - 0 = -1

slope = 6 / -1 = -6

The y intercept is where x = 0 which is given in the table (0,3) so

y intercept = 3

Point slope form is y = mx + b , so

y = -6x + 3

1. Choose the graph that represents the equation y = -x] - 1.
AVprozaik [17]

Answer:

x=−y−1

Step-by-step explanation:

y=−x−1

Step 1: Flip the equation.

−x−1=y

Step 2: Add 1 to both sides.

−x−1+1=y+1

−x=y+1

Step 3: Divide both sides by -1.

−x

−1

=

y+1

−1

x=−y−1

7x - 3x = 24
Debora [2.8K]
7x - 3x = 24
The 7x and the 3x are both like terms, so they can be combined. 7 - 3 is 4, so the equation turns into
4x = 24
Now, you want to get the x alone, so you divide both sides by 4 because it is the opposite of multiplication. 24 divided by 4 is 6, so
x = 6

Answer:

  8. yes

  9. no

  10. yes

Step-by-step explanation:

8. A horizontal line (y=3) is perpendicular to a vertical line (x=0).

__

9. A horizontal line (y=2) is parallel to a horizontal line (y=-1/2). The lines are not perpendicular.

__

10. A parallelogram is a rectangle if the sides are perpendicular. The slopes of the short sides are rise/run = -1, and the slopes of the long sides are rise/run = +1. These values have a product of -1, so the sides are perpendicular. The figure is a rectangle.

Two rules for creating a pattern are given below. Each rule begins with a number called the input and
lana66690 [7]

Answer:

A

Step-by-step explanation:

Table A

input is 5 and output is 9

Using the 2 given rules

Increase the input by 4 to get output , then

5 + 4 = 9 ← correct output

Multiply input by 2 and subtract 1 to get output , then

2 × 5 - 1 = 10 - 1 = 9 ← correct output

Table A works for both rules

George wants to rent a car for a road trip with his friends. He checked the rentals with two companies. Company A charges a non-
andre [41]

Answer:

Company A has a greater daily rate

Step-by-step explanation:

Given

Company A

Base\ Charges=\$50

Daily\ Rate = \$150

Company B

f(x) = 50(2x +1)

Required

Determine the company with greater rate

Simplify the expression of company B

f(x) = 50(2x +1)

f(x) = 50 * 2x + 50 * 1

f(x) = 100x + 50

In a linear function:

f(x) = mx + b

m represents the rates.

This implies that the rate of company B is:

Rate =100

and the rate of company A is

Daily\ Rate = \$150

By comparison:

Company A has a greater daily rate
