What is the value of x in the equation −x = 6 − 4x + 18? (1 point) 24 8 −8 −24​

Answer:

-16

Step-by-step explanation:

(n+1) 2 n=-9

Step 1 Plug in -9 for n:    (-9+1)x 2

Step 2 Add -9 and 1:      -8x2

Step 3 Multiply -8 and 2:  -16

Calculate the area of the floor:

Area = 1.6 x 2.3 = 3.68 square meters

Using the given formula: Pressure = force/area

200 = force / 3.68

Solve for force by multiplying both sides by 3.68

Force = 200 x 3.68

Force = 736 N/m^2

Correct to the nearest 5N/m^2 = 735 N/m^2

First of all we need to calculate the area of the floor and then we will find the pressure using the formula for pressure...

Last month the amount of rain that fell each day varied about the same as the month before is the right statement about the rainfall, Option c is correct.

The average distance between each data point and the mean is the mean absolute deviation of a dataset. It offers us an indication of how variable a dataset is.

The  given data in the problem is;

Two months ago,

The mean daily rainfall in a local city was 9. 4 cm.

The mean absolute deviation was 3. 5 cm

Last month

The mean daily rainfall in that city was 11. 5 cm

The mean absolute deviation was 1. 6 cm.

We can see that there was less variation last month than the month before since the mean absolute deviation is a measure of variance.

Hence Last month the amount of rain that fell each day varied about the same as the month before is the right statement about the rainfall, Option c is correct.

Answer:  x = 5

Step-by-step explanation:

(3x + 22) and (3x + 128) are supplementary angles, which means that they add up to 180, so we can write our equation.

(3x + 22) + (3x + 128) = 180

   3x + 22 + 3x + 128 = 180

                   6x + 150 = 180

                             6x = 30

                                x = 5

Answer: A

Step-by-step explanation:

About 25% scored higher; about 75% scored lower.

Answer: C

Step-by-step explanation:

The slope-intercept form of a line is given by

y = mx + b

m - slope

b - y-intercept

Segment AB lies on the line 6x + 3y = 12

6x + 3y = 12

3y = -6x + 12

​​y = -6/3​x +  12/3​  

y = -2x + 4

Comparing with the slope-intercept form,

Slope = - 2

y-intercept = 4

Segment CD lies on the line 4x + 2y = 8

4x + 2y = 8

2y = -4x + 8

y = -4/2​x +  8/2

y = - 2x + 4

Comparing with the slope-intercept form,

Slope = - 2

y-intercept = 4

Both the line segments have the same slope and the same y-intercept, so the two line segments will lie exactly on top of one another.

Therefore, the correct option is (c)

Answer:

1.) 78

2.) 162

Step-by-step explanation:

you just multiply the number outside of the parentheses by the one inside them lol

Answer:

See below.

Step-by-step explanation:

1.

y = 100 + 65x

y = 40 + 80x

100 + 65x = 40 + 80x

-15x = -60

x = 4

y = 100 + 65x = 100 + 260 = 360

(4, 360)

2.

The lines intersect at the point (4, 360).

At the point of intersection, where x = 4, it shows that by doing 4 hours of labor, both shops cost the same.

3.

Mike's:

y = 100 + 65x = 100 + 65(3) = 100 + 195 = 295

Amy's:

y = 40 + 80x = 40 + 80(3) = 40 + 240 = 280

For 3 hours of labor, Amy's shop is cheaper at $280. Mike's costs $295.

Answer:

1.  (4, 360)

2.  total cost at both repair shops is the same

3.  Amy's Auto Repair:  $280

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y=100+65x\\y=40+80x\end{cases}[/tex]

Question 1

Solve by using the Substitution Method:

[tex]\implies 40+80x=100+65x[/tex]

[tex]\implies 40+80x-65x=100+65x-65x[/tex]

[tex]\implies 40+15x=100[/tex]

[tex]\implies 40+15x-40=100-40[/tex]

[tex]\implies 15x=60[/tex]

[tex]\implies 15x \div 15=60 \div 15[/tex]

[tex]\implies x=4[/tex]

Substitute the found value of x into one of the equations and solve for y:

[tex]\implies y=40+80(4)[/tex]

[tex]\implies y=40+320[/tex]

[tex]\implies y=360[/tex]

Therefore, the point of intersection is (4, 360)

Question 2

The two lines intersect at (4, 360).  This means that the total cost at both repair shops is the same when it takes 4 hours to repair the car.  The cost at this time is $360.

Question 2

To find the cost at both repair shops if it takes 3 hours to fix the car, substitute x = 3 into both equations and solve for y:

Mike's Repair shop:

[tex]\implies y=100+65(3)[/tex]

[tex]\implies y=100+195[/tex]

[tex]\implies y=295[/tex]

Amy's Auto Repair:

[tex]\implies y=40+80(3)[/tex]

[tex]\implies y=40+240[/tex]

[tex]\implies y=280[/tex]

Therefore, Amy's Auto Repair company is the cheapest at a cost of $280.

Answer:13/15

Step-by-step explanation:

Add 7/9 and 2/3 the answer is 13/9 then divide it by 5/3 in order for you to divide get the reciprocal of 5/3 which is 3/5 then multiply it and you well get 13/15

Answer:

13/15

Step-by-step explanation:

The answer is 13/15 because:

1) In order to figure out what 7/9 + 2/3 is, we need to find the common denominator. The common denominator is 9 because 3 contains the factor 9.

7/9 + 6/9 = 13/9

We need to multiply the denominator to get to 9: 3 x 3 = 9. We have to multiply the numerator as well: 2 x 3 = 6.

2) Next, we have to divide 13/9 and 5/3. In order to divide we have to find the reciprocal of the second number. Reciprocal means to flip the fraction. The reciprocal of 5/3 is 3/5.

3) Finally, we just have to multiply 13/9 and 3/5 which is 39/45. 39/45 in simplest form is 13/15.

[tex]y\leq \dfrac12x+3[/tex]

Step-by-step explanation:

Choose 2 points on the line:  (-6, 0) and (0, 3)

[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-3}{-6-0}=\dfrac12[/tex]

point-slope form of linear equation:  [tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-0=\dfrac12(x-(-6))[/tex]
