Answer

2/3, 7/10, 11/15

Step-by-step explanation:

Given:

The line parallel to y = −x that passes through (7, 2.5).

To find:

The slope intercept form of the given line.

Solution:

Slope intercept form of the line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

On comparing y = −x with slope intercept form, we get

[tex]m=-1[/tex]

So, slope of y=-x is -1.

Slope of parallel lines are same. Thus, slope of required line is -1.

Required line passes through (7,2.5) with slope -1. So, the equation of line is

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-2.5=-1(x-7)[/tex]

[tex]y-2.5=-x+7[/tex]

Add 2.5 on both sides.

[tex]y-2.5+2.5=-x+7+2.5[/tex]

[tex]y=-x+9.5[/tex]

Therefore, the equation of the line that passes through (7, 2.5) is [tex]y=-x+9.5[/tex].

Answer:

y - 5 = - [tex]\frac{3}{5}[/tex](x + 5)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Given

5x = 3y , that is

3y = 5x ( divide both sides by 3 )

y = [tex]\frac{5}{3}[/tex] x ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{3} }[/tex] = - [tex]\frac{3}{5}[/tex] and (a, b) = (- 5, 5), then

y - 5 = - [tex]\frac{3}{5}[/tex] (x - (- 5) ), that is

y - 5 = - [tex]\frac{3}{5}[/tex] (x + 5) ← equation of perpendicular line

Answer:

x=4

Step-by-step explanation:

3(x+2) = 2(x+5)

Distribute

3x+6 = 2x+10

Subtract 2x from each side

3x-2x+6 = 2x-2x+10

x +6 = 10

Subtract 6 from each side

x+6-6 = 10-6

x = 4

Answer:

x = 4

Step-by-step explanation:

Original Equation:

3(x + 2) = 2(x + 5)

Use distributive property

3 · x = 3x

3 · 2 = 6

Your equation should look like this now:

3x + 6 = 2(x + 5)

Use distributive property for the other side

2 · x = 2x

2 · 5 = 10

Your equation:

3x + 6 = 2x + 10

Subtract 6 from both sides

3x = 2x + 4

Subtract 2x from both sides

1x = 4

Divide both sides by 1

x = 4

Answer:

A, B, & D

Step-by-step explanation:

A: Linear functions are often written in point-slope form, y=mx+b.

B: The rate of change in linear functions is always a constant slope, the m value.

C: The initial value of a linear function could be zero. It depends on the line.

D: It makes sense that the graph of a linear function is a line.

E: A vertical line is not a function. You can do the vertical line test: if a vertical line were to hit more than one point at a single x-value, the line is not a function.

Answer:

-2137

Step-by-step explanation:

     you have to subtract the two numbers then you get your answer

The number of boxes of clips that Mr. Collins has is 437 boxes.

In order to determine the number of boxes of clips that Mr. Collins has, we have to determine the number of  boxes of clips in the 54 cartons.

The  boxes of clips in the carton can be determined by multiplying 54 by 8

The  boxes of clips in the carton = 54 x 8 = 432

The second step is to add 432 to 5.

432 + 5 = 437 boxes

Answer:

[tex]x^{4}[/tex] + x² + 1

Step-by-step explanation:

One way is to divide using Synthetic division

1 |  1    - 1    1    - 1    1    - 1

     ↓      1    0     1    0     1

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

     1      0     1     0    1    0 ← remainder

Since remainder is 0 then (x - 1) is a factor of the polynomial

The quotient is of degree 1 less than the dividend, that is

quotient = [tex]x^{4}[/tex] + x² + 1

Answer:

[tex]\boxed{x^4 + x^2 + x}[/tex]
