Describe the transformation that takes f(x)=x+1 to g(x) = -x+4. Will Mark Brainliest.​
lions [1.4K]

Answer:

Reflection across y axis

Translate up by 3 units

Step-by-step explanation:

Given

f(x) = x + 1

g(x) = -x + 4

Required

Describe the transformation from f(x) to g(x)

First, take a reflection of f(x) across the y axis.

So f(x) becomes f(-x)

f(x) = x + 1 when reflected

f(-x) = -x +1

Next, translate f(-x) up by 3 units to give g(x)

g(x) = f(-x) + k

Where

k = 3

f(-x) = -x +1

g(x) = -x + 1 + 3

g(x) = -x + 4

Hence, the transformation from f(x) to g(x) includes:

Reflection across y axis

Which equation could represent p? Please please help
Andre45 [30]

Answer:

<h2>P(x) = (x+3)(x-2)^2</h2>

Step-by-step explanation:

Looking at the brackets you can see where the curve will intersect the x-axis.

The graph shows the curve intersecting at (0,-3) and (0,2).

This means:

x = -3

AND

x = 2

Rearrange the equations, equating them to 0.

x + 3 = 0

x - 2 = 0

This will be the values in the brackets.

Because the curve only touches 0,2 and DOES NOT cross it, we know that x - 2 is a repeated root, hence (x-2) is squared.

Therefore your brackets are: (x+3)(x-2)(x-2)

Which can be simplified:

(x+3)(x-2)^2

Where ^2 means squared.

Triangle Z W X is shown. Angle Z W X is a right angle. An altitude is drawn from point W to point Y on side Z X to form a right
sashaice [31]

Answer:

b = 9.1units

Step-by-step explanation:

Find the diagram attached

Using the similarity theorem of triangle

WX/XZ = WY/WX

Substitute;

b/a+5 = 6/b

b² = 6(a+5) ... 1

Also according to pythagoras theorem on triangle WYX;

b² = 6²+a²...2  

Equate 1 and 2

6(a+5) = 6²+a²

6a+30 = 36 + a²

a²-6a+36-30 = 0

a²-6a+6 = 0

a = 6±√36+4(6)/2

a = 6±√60/2

a = 6±7.745/2

a = 13.745/2

a = 6.8725

Recall that

b² = 6²+a²

b² = 36+6.8725²

b² = 83.2313

b = 9.12units

b = 9.1units

PLEASE HELP WILL MARK BRAINLIEST!!!!
MaRussiya [10]

1.

(a) The variables are:

→ y is the total cost

→ x is the number of ride tickets

→ c is the price of the fair admission

(b) The linear equation that can be used to determine the cost for

anyone who only pays for ride tickets and fair admission is

y = 1.25 x + c

(c) Because the equation is linear which means the value of y depends on

the value of x and the value of c = 5 does not change so the equation

can be used to determine the cost for anyone who only pays for ride

tickets and fair admission

2.

(a) The slope of the line is \frac{3}{4}

(b) The equation of the line in point-slope form is:

y - 3 = \frac{3}{4} (x + 4)

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

y = \frac{3}{4} x + 6

3.

The inequality that model the problem is:

20x + 10y ≥ 2000

Step-by-step explanation:

1.

The given is:

1. The county fair charges $1.25 per ticket for the rides.

2. Jermaine bought 20 tickets for the rides and spent a total of $35.00

    at the fair

3. Jermaine spent his money only on ride tickets and fair admission

4. The price of the fair admission is the same for everyone

Use y to represent the total cost and x to represent the number of

ride tickets

∵ The price of a ticket = $1.25

∵ The number of tickets = x

∵ y represents the total cost

∵ The total cost = the cost of a ticket × the number of tickets + the price

   of the fair admission

∴ y = 1.25 x + c, where c is the fair admission

∵ Jermaine bought 20 tickets

∴ x = 20

∵ Jermaine spent a total of $35.00 at the fair

∴ y = 35

- Substitute these values in the equation in step b

∴ 35 = 1.25(20) + c

∴ 35 = 25 + c

- Subtract 25 from both sides

∴ c = 5

∵ c represents a constant term (y-intercept) in the linear equation

∴ The price of the fair admission for any one is $5

(a)

The variables are:

→ y is the total cost

→ x is the number of ride tickets

→ c is the price of the fair admission

(b)

The linear equation that can be used to determine the cost for

anyone who only pays for ride tickets and fair admission is

y = 1.25 x + 5

(c)

Because the equation is linear which means the value of y depends on

the value of x and the value of c = 5 does not change so the equation

can be used to determine the cost for anyone who only pays for ride

tickets and fair admission

2.

A line goes through the points (-4 , 3) and (4 , 9)

The rule of the slope of a line is m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

∵ x_{1} = -4 and x_{2} = 4

∵ y_{1} = 3 and y_{2} = 9

∴ m=\frac{9-3}{4--4}=\frac{6}{8}=\frac{3}{4}

(a)

The slope of the line is \frac{3}{4}

(b)

The point-slope form of the equation is y-y_{1}=m(x-x_{1})

∵ y_{1} = 3 and x_{1} = -4

∵ m = \frac{3}{4}

∴ y - 3 = \frac{3}{4} (x - -4)

∴ y - 3 = \frac{3}{4} (x + 4)

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

y - 3 = \frac{3}{4} (x + 4)

(c)

The slope-intercept form of the equation is y = mx + c, where c is the

y-intercept

∵ m = \frac{3}{4}

∴ y = \frac{3}{4} x + c

- To find c substitute x and y by the coordinates of one of the two

  given points

∵ x and y are the coordinates of point (4 , 9)

∴ 9 = \frac{3}{4} (4) + c

∴ 9 = 3 + c

- Subtract 3 from both sides

∴ c = 6

∴ y = \frac{3}{4} x + 6

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

y = \frac{3}{4} x + 6

Jacob and Sarah are saving money to go on a trip

The given is:

1. They need at least $2000 in order to go

2. Jacob mows lawns and Sarah walks dogs to raise money

3. Jacob charges $20 each time he mows a lawn and Sarah charges

   $10 each time she walks a dog

4. x representing the number of lawns mowed and y representing the

   number of dogs walked

∵ x representing the number of lawns mowed

∵ Jacob charges $20 each time he mows a lawn

∴ Jacob can earn $20x

∵ y representing the number of dogs walked

∵ Sarah charges $10 each time she walks a dog

∴ Sarah can earn 10y

∵ They need at least $2000 in order to go to the trip

∴ 20x + 10y ≥ 2000

The inequality that model the problem is:

20x + 10y ≥ 2000
