Answer 1

Answer:

Flip the sign.

Step-by-step explanation:

For example if it was -2<3 youd flip the sign when you get your answer. So it would be -2>3 except itd be your answer. I just made this problem up but flip the sign!

Answers

Answer:

x = -6

Step-by-step explanation:

Distribute the 2 into the brackets:

2x + 10 = -2

leave the 2x alone on one side:

2x = -2 -10

2x = -12

Answers

Answer: y - 2 = 7(x + 6)

Explanation:

Point slope form:
y - y1 = m(x - x1)

Where y1 and x1 are the coordinate given And m is the slope.

Our coordinate is (-6,2) and slope = 7

y - 2 = 7(x -(-6))

Raul works at a movie theatre. The function f(x) represents the amount of money Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. Show all work to find f(g(x)), and explain what f(g(x)) represents.


f(x) = 2x2 + 16

g of x equals the square root of the quantity 5 x cubed

Answers

Answer:

Step-by-step explanation:

Given f(x) = 2x²+16

g(x) = √5x³

First is to get the composite function f(g(x))

f(g(x)) = f(√5x³)

To get f(√5x³), we will replace x in f(x) with √5x³ as shown:

f(√5x³) = 2(√5x³)²+16

f(√5x³) = 2(5x³)+16

f(√5x³) = 10x³+16

Hence f(g(x)) = 10x³+16

f(g(x)) will be the function of amount earned by Raul for the total number hour he works

A twons populations is 43,425. About 125 people move out of the town each month, 200 people on the average move into town. A nearby town has population of 45,000. it has no one moving in and an average of 150 people moving away every month. In about how many months will the population of the towns be equal? Write an equation that represents this situation and solve.

Answers

Answer:

After 7 months months the population of both the town will be equal.

Step-by-step explanation:

Let's assume, the population of both towns will be equal after x number of months.

Every month 125 people move out of the town and 200 people move into the town, where already 43,425 people are living. So, the population of the former town after x months is,

Every month 150 people move out of the town, where already 45,000 people are living. So, the population of the latter town after x months is,

when the population of both of the towns are same,then

Answers

Answer:

x=160°, y= 62°

Hope this helps

Answer:

∠X = 160°, ∠Y = 62°

Step-by-step explanation:

∠ABD = ∠FDC = 20° [ DF║AB ]

∠X = 180° - ∠FDC

∠X = 180° - 20° = 160°

∠FCD = ∠BCA = 98°        

∠Y = ∠CAB [ DF║AB]

∠BCA+∠CAB+∠ABC = 180°

98°+∠CAB+20° = 180°

∠CAB = 180° - 118° = 62° = ∠Y

HAVING A BAD DAY HELP
Christine bakes 20 cookies every half hour. Charlie sells 38 cookies per hour. How many cookies are left unsold if they work from 6:00 AM until noon?

Answers

Answer:

12

Step-by-step explanation:

The number of cookies that are left unsold if they work from 6:00 AM until noon is 12.

Cookies baked per hour by Christine = 20*2 =40

Cookies sold per hour by Charlie = 38

How many hours will be there between 6:00 AM and noon?

There will be 6 hours between 6:00 AM and noon.

So, Cookies baked by Christine in 6 hours = 40*6 =240

Cookies sold by Charlie in 6 hours = 38*6 =228

Number of unsold cookies =240-228 =12

Hence, the number of cookies that are left unsold if they work from 6:00 AM until noon is 12.

Given A(-1,4), B(2,-5), and C(3, 4), which coordinate pair will make AB perpendicular to CD ?

Answers

Answer:

The coordinate pair of the point D that will make AB perpendicular to CD is the D(6, 3)

Step-by-step explanation:

The slope of the given line AB can be presented as follows;

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

[tex]m =\dfrac{-5-4}{2-(-1)} = \dfrac{-9}{3} =-3[/tex]

The slope of a perpendicular line  to a given line is equal to the negative reciprocal of the slope of the given line

Therefore, the slope of the perpendicular to a line that has a slope of m is -1/m

The slope of the perpendicular to the line AB is therefore [tex]-\dfrac{1}{3}[/tex]

From which we get the equation of the perpendicular to the line AB given as follows;

y - 4 = -1/3 × (x - 3)

y - 4 = -x/3 + 1

y = -x/3 + 1 + 4

y = -x/3 + 5

When x = 6, y = -6/3 + 5 = 3

Therefore, the coordinate pair of the point D that will make AB perpendicular to CD is the D(6, 3).

Using the slope concept, it is found that the coordinate pair is:

[tex]D\left(x, \frac{x}{3}+9\right)[/tex]

The slope of a coordinate pair [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the change in y divided by the change in x, that is:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

If two segments are perpendicular, the multiplication of their slopes is -1.

For segment AB, the slope is:

[tex]m = \frac{-5 - 4}{2 - (-1)} = -\frac{9}{3} = -3[/tex]

At segment CD, we want that:

[tex]-3m = -1[/tex]

[tex]m = \frac{1}{3}[/tex]

Considering D(x,y), we have that:

[tex]\frac{y - 4}{x - 3} = \frac{1}{3}[/tex]

Writing y as a function of x:

[tex]x - 3 = 3(y - 4)[/tex]

[tex]3y - 12 = x - 3[/tex]

[tex]3y = x + 9[/tex]

[tex]y = \frac{x}{3} + 9[/tex]

Thus, the coordinate pair is:

[tex]D\left(x, \frac{x}{3}+9\right)[/tex]

Dan’s school is planning a field trip to an art museum. Bus company A charges a $60 rental fee plus $4 per student Bus company B charges $150 plus $2 per student. How many students would have to go for the cost to be the same?

Answers

Answer: 45 students

Step-by-step explanation:

Company A’s charge can be represented by: 4s+60

Company B’s charge can be represented by: 2s+150

s is the charge per student

To find the cost at which they are the same, I will set both equations equal to each other.

4s+60=2s+150

-2s -2s

2s+60=150

-60 -60

2s=90 Divide both sides by 2

s=45

So when 45 students are going, the cost for both companies are the same.
