New York City is a popular field trip destination. This year the senior class at High School A and

the senior class at High School B both planned trips there. The senior class at High School A

rented and filled 11 vans and 9 buses with 622 students. High School B rented and filled 11 vans

and 4 buses with 362 students. Each van and each bus carried the same number of students. How many students can a van carry? How many students can a bus carry?​

Step-by-step explanation:

f(x) = √x + 3

y = √x + 3

√x = y - 3

x = (y - 3)²

Hence inverse of f(x) = (x - 3)² and its domain is x >= 3.

The required domain of the inverse function F(x)= (x-3)^2 is given by ≥3

f(x)= √x+3

The inverse function can be defined as the transverse of function.

F(x) = y
y = √x + 3
x= (y - 3)^2

or
for inverse function
F(x) = (x-3)^2
The domain of function is given by greater and equal to 3

The required inverse function is F(x) = (x-3)^2 and its domain is greater and equal to 3.

1. slope = 0

2. slope = -5

3. slope = 5

4. slope = 0

5. slope=  -1

6. slope = -1/2

7. slope = 3

8. slope = -1/10

9. slope = 1/2

10. slope = -1/2

Explanation :

I won't explain every question because that'll take forever but I can explain one step by step.

An example is number 5

You have the points, ( -4 , 5 ) ( 1 , 0 )

You need to use the SLOPE FORMULA

So first put an x1 and y1 below the points -4 and 5.

then put x2 and y2 below the points 1 and 0

the slope formula is   m = y2-y1/x2-x1

plug in the numbers which will look like

0-5/1+4

It's plus 4 instead of -4 because a negative and negatives gives you a postivie

Simplify and you get m = -1

x = -6

Step-by-step explanation:

Answer:

x=-6

Step-by-step explanation:

14=-(x-8)

14=−x+8(Distribute)

flip equation:

−x+8=14

Subtract 8 from both sides

−x+8−8=14−8

−x=6

divide by -1 both sides

x=-6

Answer:

D. [tex] \frac{1}{4} [/tex]

Step-by-step explanation:

Rectangle VWXY after dilation, became compressed to rectangle V'W'X'Y'.

This makes both rectangles similar. It follows that the corresponding side lengths or segments of both figure would be proportional. Thus, the scale factor of the dilation would be:

[tex] \frac{W'X'}{WX} [/tex]

W'X' = 5

WX = 20

Plug in the values

[tex] \frac{5}{20} [/tex]

Simplify

[tex] scale factor = \frac{1}{4} [/tex]

Answer:

x is 4

GR is 10

GB is 49

Step-by-step explanation:

If U is between G and B, then GU + UB = GB .... 1

If R is between G and U, GR + RU = GU ....2

Given

GR is 3x-2

RU is 5x+7

UB is 12

GB is 15x-11

Substitute2 into 1;

Frim 1;

GU + UB = GB

(GR+RU) + UB = GB

3x-2+5x+7+12 = 15x-11

8x+17 = 15x-11

8x-15x = -11-17

-7x = -28

x = 28/7

x = 4

Get GR:

GR = 3x-2

GR = 3(4)-2

GR = 12-2

GR = 10

Get GB:

GB = 15x-11

GB = 15(4)-11

GB = 60-11

GB = 49

x-intercept(s): (3,0)

y-intercept(s): (0,−2)

Step-by-step explanation:

Answer:

x=3 and y=-2

Step-by-step explanation:

2x - 3y = 6

cancel out the y

2x - 3(0) = 6

2x = 6

divide both sides by 2

x = 3

2x - 3y = 6

cancel out the x

2(0) - 3y = 6

-3y = 6

divide both sides by -3

y = -2

Hope this helps!!

Step-by-step explanation:

y = 2x

y = x + 1

y-1 = x

y = 2x

y = 2 (y - 1)

y = 2y - 1

y = -1

Answer:

  ∠x = 30°

Step-by-step explanation:

The measure of an inscribed angle is half the measure of the arc it subtends. Angle BAC is half the measure of arc BC.

Arc ABC is a semicircle, so measures 180°. Of that, arc AB is 120°, so the remainder, 180° -120° = 60° is the measure of arc AB.

Angle x is half that, or 60°/2 = 30°.

The measure of angle x is 30°.

Answer:

x=1

Step-by-step explanation:

Answer:

Begin by subtracting the amount that they already have made from the total needed, making: 12,500−1,0250=11,250.

So, the amount needed to raise more is $11,250, and we have 50 students. To make the amount needed for the trip, divide the amount needed by each student, for the amount needed to raise by each student. 1125050=225

Each student must make $225 for the trip to happen.

Answer:

The answer is

y = 6x + 43

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

To find the equation of the parallel line we must first find the slope of the original line

The original line is y = 6x + 1

Comparing with the general equation above

Slope = 6

Since the lines are parallel their slope are also the same

Slope of parallel line = 6

The equation of the line using point (-7,1) and slope 6 is

We have the final answer as

y = 6x + 43

➤ How to solve ?

⠀⠀⠀⠀

That's quite easy but you need to recall the BODMAS rule .

⠀⠀⠀⠀

BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction

⠀⠀⠀⠀

In this equation we will solve the bracket then we will apply further BODMAS rule

SolutiOn :

➠ 7x + 31 = 8x - 1 ( 27x + 3 ) -3

➠ 7x + 31 = 8x - 27x - 3 - 3

Now, we will bring the variable on left hand side and constants on right hand side

➠ 7x - 8x + 27x = - 31 - 3 - 3

➠ 26x = -37

➠ x = -37/ 26

➠ x = - 1.42

∴ The value of x is -1.42 .
