[tex]\huge\rm\underline{Answer}[/tex]

✧ Rational numbers are represented on the number line by dividing a unit into as many divisions as the denominator of the rational number

Here , Each unit is divided into 7 equal parts . It means denominator of the rational number is 7.

So , A represents -10/7

So , B represents -6/7

So , C represents 3/7

So , D represents 15/7

Answer:

A) 30x

Step-by-step explanation:

5(x - 2x + 6x + 10)

Distribute:

5(x) + 5(-2x) + 5(6x) + 5(10)

5x - 10x + 30x + 50

Therefore, 5(x - 2x + 6x + 10) is equivalent to 5x - 10x + 30x + 50

Hope this helps!

Answer:

A) 30x

Step-by-step explanation:

Given equation:

5(x – 2x + 6x + 10) = 5x – 10x + ? + 50

Let the "?" be represented as "a". Then,

⇒ 5(x – 2x + 6x + 10) = 5x – 10x + a + 50

[Right hand side] Put all the terms inside a parenthesis (except "a").

⇒ 5(x – 2x + 6x + 10) = 5x – 10x + a + 50

⇒ 5(x – 2x + 6x + 10) = (5x – 10x + 50) + a

Isolate the "a" on one side by subtracting the terms inside the parenthesis.

⇒ 5(x – 2x + 6x + 10) - (5x – 10x + 50) = (5x – 10x + 50) + a - (5x – 10x + 50)

⇒ 5(x – 2x + 6x + 10) - 5x + 10x - 50 = a

[Left hand side] Simplify the distributive property

⇒ 5(x – 2x + 6x + 10) - 5x + 10x - 50 = a

⇒ (5x – 10x + 30x + 50) - 5x + 10x - 50 = a

[Left hand side] Open the parentheses

⇒ (5x – 10x + 30x + 50) - 5x + 10x - 50 = a

⇒ 5x – 10x + 30x + 50 - 5x + 10x - 50 = a

[Left hand side] Combine like terms and simplify

⇒ 5x – 10x + 30x + 50 - 5x + 10x - 50 = a

⇒ x(5 – 10 + 30 - 5 + 10) + (50 - 50) = a

⇒ x(30) = a

[Left hand side] Open the parenthesis and simplify

⇒ x(30) = a

⇒ 30x = a = ?

Therefore, the correct option is A (30x).

Answer:

c. y=4x+24

Step-by-step explanation:

To identify the equation, the equation must satisfy the points (-5,3).

putting x as -5 should give us y=3

c. y = 4x + 23

y = 4 * (-5) + 23

y = -20 + 23

y = 3

[tex]\rule{300}{1}\\\dashrightarrow\large\textsf{\textbf{\underline{Given question:-}}}[/tex]

Identify an equation in slope-intercept form for the line parallel to y = 4x - 9

that passes through (-5,3).

[tex]\dashrightarrow\large\textsf{\textbf{\underline{\underline{Answer and how to solve:-}}}}[/tex]

If lines are parallel to each other, they have the same slope.

If a line is parallel to [tex]\bold{y=4x-9}[/tex], and the slope of this line is 4, then the slope of the line that's parallel to [tex]\bold{y=4x-9}[/tex] also has a slope of 4.

All right, we know the slope, but that's part of the slope-intercept equation,

We also need to identify the y-intercept; one way to find it (the one I always use) is the point-slope form.

Point-slope form looks like so:-

[tex]\longmapsto\sf{y-y_1=m(x-x_1)}[/tex]

Replace y1 with 3, m with 4, and x1 with -5:-

[tex]\longmapsto\sf{y-3=4(x-(-5)}[/tex]

On simplification,

[tex]\longmapsto\sf{y-3=4(x+5)}[/tex]

On further simplification,

[tex]\longmapsto\sf{y-3=4x+20}[/tex]

On further simplification,

[tex]\longmapsto\sf{y=4x+20+3}[/tex]

Final equation:-

[tex]\longmapsto\sf{y=4x+23}[/tex]

Answer:

Step-by-step explanation:

Using the normal distribution, it is found that he needs a score of 605 in exam b in order to do equivalently well as he did on exam a.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

For the z-score for exam a, we have that the parameters are given as follows:

[tex]X = 22, \mu = 40, \sigma = 10[/tex]

Hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{22 - 40}{10}[/tex]

Z = -1.8.

Then, for the equivalent grade X in exam B, we have that:

[tex]Z = -1.8, \mu = 650, \sigma = 25[/tex]

Then:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]-1.8 = \frac{X - 650}{25}[/tex]

X - 650 = -1.8 x 25

X = 605.

Answer:

y = (-2/3)x + 4 or

3y = -2x + 12

Step-by-step explanation:

Slope of line passing through (x₁, y₁) and (x₂, y₂) is given by
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

In this particular case where the points are (6,0) and (0,4) we get the slope as (4-0)/(0-6) = -2/3

Equation of a line with slope m and y intercept c is given by

y = mx + c

substituting for m we get the equation y = (-2/3)x + c

Substituting the first point (6,0) we get

0 = (-2/3)(6) + c or -4 + c = 0 or c =4

Therefore y = (-2/3)x + 4 or multiplying both sides by 3 we get

3y = -2x + 12

Remark

You have an isosceles triangle. That means that the angles opposite the marked sides are equal. So mark the angle on the lower left of the triangle as 50 degrees.

The solution to problem depends on the fact that the sum of the two inside angles of the triangle (each of which is marked as 50 degrees) not supplementary to the exterior angle, are still equal to the exterior angle.

Givens

<1 = 50 degrees

<2 = 50 degrees

Exterior angle = 15x + 25   Substitute the givens into the equation

Equation

<1 + <2 = 15x + 25

Solution

50 + 50  = 15x + 25                       Combine the left side

100 = 15x + 25                               Subtract 25 from both sides

100 - 25 = 15x + 25 - 25                Combine

75 = 15x                                          Divide both sides by 15

75/15 = 15x/15                      

5 = x

Answer

<1 = 50 degrees

<2 = 50 degrees

15x + 25 = 75 + 25 = 100

The linear equations for the system: y = x + 70 and y = 4x + 10

She'll attend 20 classes/month

The graph for the solution (20, 95) is in the image attached below

A linear equation can expressed in slope-intercept form, as, y = mx + b.

Linear equation for the first membership plan:

b = 70

m = 1

x = number of classes

y = total amount

Equation for the first membership plan: y = x + 70

Linear equation for the second membership plan:

b = 10

m = 4

x = number of classes

y = total amount

Equation for the second membership plan: y = 4x + 10

The system of equations are:

y = x + 70

y = 4x + 10

The solution is the point at which the line for both equations intersect on the graph as shown in the image attached below, which is: (20, 95).

This means Mary must attend 20 classes for each membership plan, she must attend 20 classes to pay the same total amount of $95 per month.
