Answer:

Yes

Step-by-step explanation:

To find if the point (3,4) a solution to the linear equation y=4x-8 you need to substitute (3,4) into y=4x-8

(x,y)

(3,4)

x=3 and y=4

Subistute:

4=4(3)-8

4=12-8

4=4 which is correct so the answer is yes (3,4) is a solution for y=4x-8

Answer:

x=5 and y=6

Step-by-step explanation:

Answer:

x=5, y=6

Step-by-step explanation:

-6x + 6y = 6

If we divide this by 6 (which we can do because it is an equation), we can simplify this by a lot.

-6x + 6y = 6

-x + y = 1 <-- NEW EQUATION #1

We can also simplify -6x + 3y = -12 by dividing everything by 3.

-6x + 3y = -12

-2x + y = -4 <-- NEW EQUATION #2

Substitution is fairly easy for this problem.

Isolate the variable

-x + y = 1

y = x + 1

Now substitute (x+1) for where you see y in the second equation.

-2x + (x + 1) = -4

-x + 1 = -4

x = 5

Now substitute 5 for x.

-(5) + y = 1

y = 6

Answer: 30

Step-by-step explanation:

Devon drove 30 miles in 1 hour because 120/4 is 30

Answer:

X=0

Step-by-step explanation:

[tex]8(1 \times 5x) + 5 = 13 + 5x \\ 8 + 40x + 5 = 13 + 5x \\ 40x + 13 = 13 + 5x \\ 40x - 5x = 13 - 13 \\ 35x = 0 \\ x = 35 \times 0 \\ x = 0[/tex]

The solution to the equation is x = 0.

Here, we have,

Let's solve the equation step by step:

Distribute the 8 to the terms inside the parentheses:

8 + 40x + 5 = 13 + 5x

Combine like terms on both sides of the equation:

40x + 13 = 5x + 13

Subtract 5x from both sides to isolate the variable terms on one side:

40x - 5x + 13 = 5x - 5x + 13

Simplifying:

35x + 13 = 13

Subtract 13 from both sides to isolate the variable term:

35x + 13 - 13 = 13 - 13

Simplifying:

35x = 0

Divide both sides of the equation by 35 to solve for x:

35x/35 = 0/35

Simplifying:

x = 0

Therefore, the solution to the equation is x = 0.

Answer:

y=3x. .................

Answer:

A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.

For example we have y=5x−8 and we can substitute this value of y in the other equation

4x+3y=33

4x+3(5x−8)=33 we can solve now for x

4x+15x−24=33

19x=33+24

19x=57

x=5719=3.

y can be obtained from the first equation

y=5x−8

y=5⋅3−8=15−8=7

Then x=3 and y=7.

Step-by-step explanation:

Answer:

x = 3

y = 7

Step-by-step explanation:

y = 5x - 8  ---------------(I)

4x + 3y = 33 ------------(II)

Substitute y = 5x - 8 in equation (II)

4x + 3 (5x - 8) = 33  

4x + 3*5x - 8*3 = 33

4x + 15x - 24 = 33           {Combine like terms}

      19x  - 24 = 33            {Add 24 to both sides}

            19x = 33 + 24

           19x = 57           {Divide both sides by 19}

             x = 57/19

x = 3

Substitute x = 3 in equation (I)

y = 5*3 - 8

y = 15 - 8

y = 7

Given

[tex]Expression = 40\% * 75[/tex]

[tex]Priya = \frac{2}{5} * 75[/tex]

Required

Is Priya correct?

We start by simplifying the expression.

[tex]Expression = 40\% * 75[/tex]

Express 40% as fraction

[tex]Expression = \frac{40}{100} * 75[/tex]

Simplify fraction: Divide numerator and denominator by 20

[tex]Expression = \frac{40/20}{100/20} * 75[/tex]

[tex]Expression = \frac{2}{5} * 75[/tex]

By comparing:

[tex]Expression = \frac{2}{5} * 75[/tex]

and

[tex]Priya = \frac{2}{5} * 75[/tex]

We can conclude that Priya is correct because:

[tex]40\% = \frac{2}{5}[/tex]
