Step-by-step explanation:

f(x) = -|x + 9|

compared to

f(x) = |x|

It has been moved 9 units left compared to the graph of f(x) = |x|.

It reflects over the x-axis.

Answer:

Let the truck is driven X miles per day

Charges of company A will be = 90+0.4X

Charges of company B will be =30+0.7X

Let us find out value of X when charges of both companies are same

which means that   90+0.4 X= 30+0.7X

                            90-30      = 0.7X-0.4X

                            60    = 0.3X

                             60/0.3 = X

                             X= 200

The charges of both companies will be same if truck is driven 200 miles per day

Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B)

Answer:

56 underwater breathing potions.

Step-by-step explanation:

Written algebraicly, f=m+10 and b=3m+2, with f being flying potions, b being breathing underwater, and m being mind reading potions. We know that f+b+m=102, so replace f and b with the equations. You get m+10 + 3m+2 + m +102. Combine like terms to get 5m+12+102. Subtract 12 from both sides to get 5m=90, and divide both sides by 5 to get m=18. Now take b=3m+2 and replace m with 18. Now you have b=3(18)+2. 3 times 18 is 54, plus 2 is 56. :)

I'm sorry if this is incorrect, but I think the answer is [tex]-2, \sqrt{5}, 4, 3^2[/tex]

Explanation: A negative number will always be the least. 3 squared is actually 3*3 and that would be 9. The square root of 5 is 2.2360679775 which is less than 4 so that would go in the second place. I hope this makes sense! :)

Answer:

525 students

Step-by-step explanation:

84/4 is 21. The ratio is 1 teacher to every 21 students. There are 25 teachers in the entire school. If you multiply that by 21, there are 525 students in the entire school.

Hey there!

[tex]5x-3x=6x-8[/tex]

Combine like terms.

[tex](5x+-3x)=6x-8\\2x=6x-8[/tex]

Subtract 6x from both sides of the equation.

[tex]2x-6x=6x-8-6x\\-4x=-8[/tex]

In the last step, we will divide both sides by -4.

Answer: x = 2

Step-by-step explanation: Aquí esta :

Simplificar 5x - 3x y eso se de 2x

1.) 2x = 6x-8

Sustraer 6x-2x

2.) 2x-6x= -8

Y entonces deberías haber obtenido 4x

3.) -4x=-8

Dividir ambos lados por -4

4.) x = -8/-4

Dos negativas hacen una positivo

5.) x = 8/4

Finalmente, la repuesta es :

6.) x = 2

Answer: 1,000

Step-by-step explanation:

1,750 divided by 1.75 =1,000

Answer:

1,000

Step-by-step explanation:

If the class wants to raise a total of $1,750 and make a profit of $1.75 from each candy bar that gets sold then you take the total and divide it by the amount of profit each bar makes. So you do 1,750 divided by 1.75 and that gives you 1,000. So the class must sell 1,000 candy bars to reach their goal.

Answer:

Step-by-step explanation:

(13 - 3)/(1 + 4) = 10/5= 2

y - 13 = 2(x - 1)

y - 13 = 2x - 2

y = 2x + 11

x = # of miles

$59.31 = $31 + $0.19x

Subtract $31 from both sides

$28.31 = $0.19x

Divide both sides by $0.19

Step-by-step explanation:

The equation which can be represented using the picture displayed on the number line is Three-fourths divided by one-eighth = 6

The number of steps or marked points can be obtained using the relation :

Length of line ÷ Distance between each marked points

3/4 ÷ 1/8 = 6

Therefore, the expression which represents the scenario on the number line is 3/4 ÷ 1/8 = 6

Answer:

answer is D

The equation of the line that is perpendicular to the given line and passes through the point (3,0) is 3y - 5x = -15.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have the points as (-3, 2) and (2, -1).

So, the slope of line

slope = (-1 -2)/ (2 -(-3))

slope = -3/5

So, the slope for the perpendicular line is

slope= 5/3

Now, using the slope intercept form

y= mx+ b

y= 5/3x + b

and, the line passes through (3, 0)

0= 5/3(3)+ b

b= -5

Then, the equation of line is

y= 5/3x -5

3y - 5x = -15

The midpoint of a line segment means a point that lies in the mid of the given line segment. The coordinates of point B are (7, -4).

Midpoint, as the word suggests, means the point which lies in the middle of something. The midpoint of a line segment means a point that lies in the mid of the given line segment. Suppose we've two endpoints of a line segment:

A(p,q), and B(m,n)

Then let the midpoint be M(x,y) on that line segment. Then, its coordinates are:

[tex]x = \dfrac{p+m}{2}[/tex]

and

[tex]y = \dfrac{q+n}{2}[/tex]

Given that the midpoint of AB is M whose coordinates can be written as,

The x-coordinate of point B,

[tex]x_m = \dfrac{(x_A + x_B)}{2}[/tex]

[tex]5 = \dfrac{(3 + x_B)}{2}[/tex]

10 = 3 + x

x = 10 - 3

x = 7

The y-coordinate of point B,

[tex]y_m = \dfrac{(y_A + y_B)}{2}[/tex]

[tex]1 = \dfrac{(6 + y_B)}{2}[/tex]

2 = 6 + y

y = 2 - 6

y = -4

Hence, the coordinates of point B are (7, -4).
