hope it helps :)

Answer:

50

Step-by-step explanation:

60-x*100=20

6000-100x=20x

6000=20x+100x

6000= 120x

Answer:

The slope of the line that passes through the points M(-3, 5) and N(1, 8) in decimal form is 0.75

Step-by-step explanation:

The given points are M(-3, 5) and N(1, 8)

The formula for finding the slope, m, given the coordinates of two points on the line is given as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where, (x₁, y₁) = (-3, 5), and (x₂, y₂) = (1, 8), we have;

[tex]Slope, \, m =\dfrac{8-5}{1-(-3)} = \dfrac{3}{4} = 0.75[/tex]

The slope, m = 0.75

The slope of the line that passes through the points M(-3, 5) and N(1, 8) in decimal form = 0.75.

The x- intercept is -4 because it is where the line crosses the x-axis.

Answer:

x ≈ 38.7°

Step-by-step explanation:

Using the tangent ratio in the right triangle.

tanx = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{8}{10}[/tex] , thus

x = [tex]tan^{-1}[/tex] ([tex]\frac{8}{10}[/tex] ) ≈ 38.7° ( to the nearest tenth )

Answer:

Paayal sold 180 cookies and Parvathy sold 20 cookies.

Step-by-step explanation:

From the information given, you can write the following equations:

x+y=200 (1)

0.05x+0.10y=11 (2), where:

x is the amount of cookies that Paayal sold and y is the amount of cookies that Parvathy sold.

First, you can solve for x in (1):

x=200-y (3)

Now, you can replace (3) in (2):

0.05(200-y)+0.10y=11

10-0.05y+0.10y=11

0.05y=1

y=1/0.05

y=20

Finally, you can replace the value of y in (3) to find x:

x=200-y

x=200-20

x=180

According to this, the answer is that Paayal sold 180 cookies and Parvathy sold 20 cookies.

Answer:

[tex]y=2x-1[/tex]

Step-by-step explanation:

The equation of the line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

The question provides both the slope m=2 and the y-intercept b=-1.

Thus, substituting:

Step-by-step explanation:

The positive value of p from the equation is; p = 3

This is about absolute values.

10 = 43 - |7p + 12|

10 - 43 = - |7p + 12|

-33 = - |7p + 12|

divide both sides by -1 to get;

33 = |7p + 12|

Answer:

This is a function

Step-by-step explanation:

This is a function because x is not repeated in any of the pairs. As long as x doesn't repeat, it is a function. y can repeat, but not x.

Step-by-step explanation:

i took all the test and got a hundred

if we graph his distance with respect to time as a line then slope of line is 45.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Arturo after 3 hours of driving is 135 miles from home. After 5 hours of driving, he is 225 miles

from home

Let the two points are (3, 135) and (5,225)

m=225-135/5-3

=90/2

=45

Hence, if we graph his distance with respect to time as a line then slope of line is 45.

Answer:

x=-4

x=14

Step-by-step explanation:

Absolute Value Equation entered :

     3|5-x|+2=29

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     3|-x+5|+2 = 29

Another term is moved / added to the right hand side.

     3|-x+5| = 27

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is 3|-x+5|

For the Negative case we'll use -3(-x+5)

For the Positive case we'll use 3(-x+5)

STEP

3

:

Solve the Negative Case

     -3(-x+5) = 27

    Multiply

     3x-15 = 27

    Rearrange and Add up

     3x = 42

    Divide both sides by 3

     x = 14

STEP

4

:

Solve the Positive Case

     3(-x+5) = 27

    Multiply

     -3x+15 = 27

    Rearrange and Add up

     -3x = 12

    Divide both sides by 3

     -x = 4

    Multiply both sides by (-1)

     x = -4

    Which is the solution for the Positive Case
