write an equation in slope-intercept form for the line. slope=4,y-intercept=3

Answers

Answer:

y = 4x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4 and c = 3, then

y = 4x + 3 ← equation of line

The value of y is directly proportional to the value of x. If y = 24 when x = 6, what is the value of y when x = 48?

Answers

Answer:

192

Step-by-step explanation:

We know that x is 1/4 of y, since 6 is 1/4 of 24. Therefore, we can multiply 48 by 4 to get 192!

A. y = -x - 7
B. y = -x - 1 C. y = 7x + 1
D. y = x + 7

Answers

The answer is D

We have m=a= (y2-y1)/(x2-x1)=(6-3)/(-1+4)=1
Y=x+ b
For the b, we have : (-1,6) : 6= -1 + b
b=7

Kate's math homework had a set of equations and a one-word problem. She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total, how many equations did she solve

Answers

Answer:

15 equations

Step-by-step explanation:

Let

Number of equations in the homework = x

There is only a one-word problem

y = amount of time used to solve the word problem

She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,

Total = 3x + y

52 = 3x + 7

Subtract 7 from both sides

52 - 7 = 3x + 7 - 7

45 = 3x

Divide both sides by 3

x = 45 / 3

= 15

x = 15 equations

Therefore, she solved 15 equations

5x + 1 = 6x - x
I need help on this problem may you help

Answers

Answer:

Step 1: Simplify both sides of the equation.

5x+1=6x−x

5x+1=6x+−x

5x+1=(6x+−x)(Combine Like Terms)

5x+1=5x

5x+1=5x

Step 2: Subtract 5x from both sides.

5x+1−5x=5x−5x

1=0

Step 3: Subtract 1 from both sides.

1−1=0−1

0=−1

Answer:

There are no solutions.

 

Step-by-step explanation:

Answer:

no solution

Step-by-step explanation:

Given

5x + 1 = 6x - x , that is

5x + 1 = 5x ( subtract 1 from both sides )

5x = 5x - 1 ( subtract 5x from both sides )

0 = - 1 ← not possible

This indicates the equation has no solution

Hello!

[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]

[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]

Find the inverse by swapping the x and y variables:

[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]

Begin simplifying. Multiply both sides by 4y - 5:

[tex]x(4y - 5) = 2y + 2[/tex]

Start isolating for y by subtracting 2 from both sides:

[tex]x(4y - 5) -2 = 2y[/tex]

Distribute x:

[tex]4yx - 5x - 2 = 2y[/tex]

Move the term involving y (4yx) over to the other side:

[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]

Factor out y and divide:

[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]

Use this equation to evaluate [tex]f^{-1}(3)[/tex]

[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]
