Answer:

Slope 1: [tex]m=0[/tex]

Slope 2: [tex]m=5[/tex]

Slope 2 is bigger than slope 1.

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Step-by-step explanation:

Step 1: Define

Slope 1

Point (-2, 3)

Point (1, 3)

Slope 2

Point (4, 21)

Point (9, 46)

Step 2: Find slope m

Slope 1

Substitute:                    [tex]m=\frac{3-3}{1+2}[/tex]Subtract/Add:               [tex]m=\frac{0}{3}[/tex]Divide:                          [tex]m=0[/tex]

Slope 2

Substitute:                   [tex]m=\frac{46-21}{9-4}[/tex]Subtract:                      [tex]m=\frac{25}{5}[/tex]Divide:                         [tex]m=5[/tex]

We know that 5 is greater than 0. ∴ Slope 2 is bigger than slope 1.

The first slope is: m = 0/3 OR m = 0
The second slope is: m = 5

How many solutions does this linear system have? y = 2x – 5 –8x – 4y = –20 one solution: (–2.5, 0) one solution: (2.5, 0) no solution infinite number of solutions

Answers

Answer: b. one solution: (2.5, 0).

Step-by-step explanation:

y = 2x - 5

-8x - 4y = -20

-8x - 4y = -20

-8x - 4 * (2x - 5) = -20

-8x - 8x + 20 = -20

20 + 20 = 16x

16x = 40

x = 40/16

x = 2.5   y = 2x - 5 = 2 * 2.5 - 5 = 5 - 5 = 0

(x, y) = (2.5, 0)

The system of equations will have a unique solution (2.5, 0)

What is system of equations?

A system of equations is a set or collection of two or more equations with the same variables. The common solutions are the intersecting points of the equations.

Given is a system of linear equations y = 2x-5 and -8x-4y = -20

y = 2x-5......(i)

-8x-4y = -20

Rearranging the equation,

8x+4y = 5

2x+y = 20

y = 20-2x.......(ii)

Solving the equation,

20-2x = 2x+5

15 = 4x

x = 2.5

Put x = 2.5 in eq(i)

y = 2(2.5)-5

y = 0

Now, determining how many solutions do this system has,

Ratios of the coefficient,

1/1, 1/4, -1

Since, 1/1 ≠ -1

Therefore, the system of the equation has only one solution.

Hence, the system of equations will have a unique solution (2.5, 0)

Answer:

210 is the number of midsized cars

Step-by-step explanation:

Assume x is the number of midsized cars

So you can create the equation 70/100=x/300

4+(2x−7)3=−5 ?

Answers

Answer: x = 2.

Step-by-step explanation: Step 1: Simplify both sides of the equation.

4+(2x−7)(3)=−5

4+(2x)(3)+(−7)(3)=−5(Distribute)

4+6x+−21=−5

(6x)+(4+−21)=−5(Combine Like Terms)

6x+−17=−5

6x−17=−5

Step 2: Add 17 to both sides.

6x−17+17=−5+17

6x=12

Step 3: Divide both sides by 6.

6x /6  =  12 /6

x = 2.

it would be -3x+2x if you were talking about the whole question like 4+(2x-7)3=-5 it would be x=2
