f(x) = -2x + 7

Consider the function below. Find f(5)

Answers

Answer 1

Answer:

-3

Step-by-step explanation:

You replace the x in the equation for 5 so the problem to work it out would be f(x)=-2(5)+7

then you just solve the equation normally

Answer 2

Answer:

-3

Step-by-step explanation:

f(x)=-2x+7

f(5)=-2×5+7

=-10+7

Show me how to find x using the correct equation shown here (geometry)

Answers

Answer:

x = 13

Step-by-step explanation:

The 2 angles same- side interior angles and sum to 180°

Then the equation to use to find x is

12x - 29 + 4x + 1 = 180

16x - 28 = 180 ( add 28 to both sides )

16x = 208 ( divide both sides by 16 )

x = 13

Answer:

13

Step-by-step explanation:

Angles ( 12x - 29 ) and ( 4x + 1 ) are co - interior angles.

Sum of co - interior angles are supplementary.

12x - 29 + 4x + 1 = 180

12x + 4x - 29 + 1 = 180

16x - 28 = 180

16x = 180 + 28

16x = 208

x = 208 / 16

x = 13

Item

Cost (S)

6.00

6.00

popcom

candy

3.50

Answers

Answer:

6x + 25 ≤ 135

Step-by-step explanation:

Maximum amount to spend = $135

Boxes of popcorn = 2

Boxes of candy = 3

Cost per box of popcorn = $6

For 3 boxes = $6 * 3 = $18

Cost per box of candy = $3.50

For 2 boxes = $2 * 3.50 = $7

Item cost = Cost of candy and popcorn = $18 + $7 = $25

Ticket price = $6

Inequality to find number of friends ;

Let number of friends = x

Ticket cost = 6x

Hence ;

Ticket cost + item cost ≤ 135

6x + 25 ≤ 135

Consider circle O, where mBD =70° and mCA = 170°

m∠BPD: ____°.

mBC + mAD = ____°.

Answers

Answer:

m∠BPD: 120°

mBC + mAD =120°

Step-by-step explanation:

m∠BPD: 120°mBC + mAD =120°What is angle?

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

Given:

mBD =70°

mCA = 170°

So,

m∠BPD= 1/2( (m∠BD + m∠CA))

=1/2(170+70)

=1/2*240

=120

and,

mBC + mAD = 360 - ( 70 + 170 )

                    = 360 - 240

mBC + mAD = 120°

The factors of the quadratic function g(x) are (5x-1) and (x+4). What are the solutions to the equation g(x)=0?

due tmr pls help!

Answers

Given:

The factors of the quadratic function g(x) are (5x-1) and (x+4).

To find:

The solutions to the equation g(x)=0.

Solution:

If the factors of the quadratic function g(x) are (5x-1) and (x+4), then the function is defined as:

[tex]g(x)=(5x-1)(x+4)[/tex]

We need to find the solutions to the equation g(x)=0. So,

[tex]g(x)=0[/tex]

[tex](5x-1)(x+4)=0[/tex]

Using zero product property, we get

[tex]5x-1=0[/tex] and [tex]x+4=0[/tex]

[tex]x=\dfrac{1}{5}[/tex] and [tex]x=-4[/tex]

Therefore, the solutions to the equation g(x)=0 are [tex]x=\dfrac{1}{5}[/tex] and [tex]x=-4[/tex].
