Find (fog)(x) (gof)(x), if f(x) = 1 - 5x; g (x) = |2x + 3| x

Answers

Step-by-step explanation:

f (x) = 1 - 5x

g (x) = 2x + 3

find (fog) (x)

it's a composite function so basically we substitute x = 2x + 3 where we see x in f (x) = 1 - 5x

so doing that we'll get

1 - 5(2x + 3)

next expand your brackets

1 - 10x + 15

equate to 0 to make things easier

1 - 10x + 15 = 0

make x the subject

1 + 15 = 10x (this is the same as 10x = 1 + 15)

x = 16/10 (you can leave it as a fraction)

fog(x) = 16/10

find gof (x)

we'll do the same thing again

2(1-5x) + 3

2 -10x + 3 = 0

2 + 3 = 10x

10x = 5

x = 5/10 (reduce)

x = 1/2

gof (x) = 1/2

A builder is buying boxes of nails. She has $187 to spend and each box of nails costs $4.

Answers

She can buy 46 boxes

Answer:

46 boxes of nails

Step-by-step explanation:

She has $187 to spend, the maximum.

187/4 = 46.75

Since she cannot buy 0.75 of a box of nails, she can only buy 46. So she is left with an extra $3 and buys 46 boxes of nails.

A scale drawing of triangle ABC has side lengths of 2 centimeters (cm), 4.8 cm, and 5.2 cm. The scale drawing was drawn using the scale of 1 cm=4 inches.
Raquel creates a different scale drawing of the original triangle ABC with the scale factor 116.
What are the side lengths in Raquel's scale drawing?
-1 in., 2.4 in., and 2.6 in.
-0.5 in., 1.2 in., and 1.3 in.
-8 in., 19.2 in., and 20.8 in.
-128 in., 307.2 in., and 332.8 in.

Answers

Step-by-step explanation:

I am not sure this is typed all correctly.

what I understand here :

there is an original triangle ABC in inches.

then, using the scale 1 cm = 4 inches a smaller triangle A'B'C' was created.

the side lengths of A'B'C' are 2cm, 4.8cm, 5.2cm.

due to the scale of 1 cm = 4 inches that means ABC has the side lengths 8 inches, 19.2 inches, 20.8 inches.

and now, another scaled triangle A"B"C" is drawn in inches based on ABC with a scan factor of 1/16 (is that correct ?).

that means that all side lengths are divided by 16 for the resulting triangle.

8 inches /16 = 0.5 inches

19.2 inches / 16 = 1.2 inches

20.8 inches / 16 = 1.3 inches

so, the second answer option is correct.

a family of four goes to a movie theatre and spends $26.50. they buy 2 tickets for adults, and 3 boxes of popcorn at $2.50 per box. what is the cost of one adult ticket

Answers

Answer:

$9.5

Step-by-step explanation:

3x2.50= 7.50

26.50-7.5 =19

19/2 = 9.5

9.5 for one adult ticket

Hi!

First, let's add (or multiply) the boxes of popcorn.

2.50 + 2.50 + 2.50 (or 2.50 x 3) is 7.50. so the popcorn all together is $7.50.

Next, we subtract the popcorn cost from the cost altogether.

26.50 - 7.50 = $19

Next, we divide the $19 by two.

19 ÷ 2 = 9.50

To make sure this is true, what we do is multiply 2 x 9.50.

2 x 9.50 = 19.

So 9.50 is your answer.

(NOTICE: your problem says a family of 4. you didn't give me the total for the other 2 people who were going to the movie, so this is just my estimate for just those 2 adults. If it's not correct, that is the reason why, otherwise, it is the answer.)

Hope this helps!

Sandra and Peter together weigh 275 pounds. Sandra and
Martin together weigh 245 pounds. All three together
weigh 410 pounds. What is Sandra's weight alone?

Answers

Answer:

110 pounds

Step-by-step explanation:

Let the weight of Sandra, Peter and Martin be S, P and M pounds respectively.

S +P= 275 -----(1)

S +M= 245 -----(2)

S +P +M= 410 -----(3)

(3) -(1):

S +P +M -(S +P)= 410 -275

S +P +M -S -P= 135

M= 135

Substitute M= 135 into (2):

S +135= 245

S= 245 -135

S= 110

Thus, Sarah weighs 110 pounds.

Answer:

7x +40x = 204x +30 = 110°3x +10 = 70°

Step-by-step explanation:

The marked angles are supplementary, so you have ...

(4x +30) +(3x +10) = 180

7x +40 = 180

Subtracting 40 gives ...

7x = 140

x = 140/7 . . . . . divide by the coefficient of x

x = 20

Then the angle measures are ...

4x +30 = 4·20 +30 = 110°

3x +10 = 3·20 +10 = 70°

A flywheel, rotating about its axis at a rate of 4 rev/s is acted upon by a torque of 25 Nm for 10 sec. If the wheel has moment of inertia of 1.2 kgm^2, what would be the speed of the wheel at the end in rev/s? Pleasantville police officers Fred and Barney were dispatched to investigate a robbery alarm call at the Hop-In liquor store. Central dispatch advised the responding units that they had attempted to call the store by phone, but there had been no answer. Upon arrival at the Hop-In, responding officers found the front door standing wide open and a male store clerk lying on the floor inside, deceased from an apparent gunshot wound to the chest. The cash register was empty and the store had been ransacked.Officers quickly reviewed the stores security videotape for evidence. The video depicted two male suspects, one wearing a red hooded sweatshirt and the other wearing a green T-shirt and blue baseball cap. Officers broadcast the suspects descriptions to other Pleasantville officers, and within an hour, two suspects were under arrest for the robbery and murder of the store clerk. The suspects were identified as Larry and Moe. Larry and Moe were booked into the Pleasantville jail and placed in separate cells pending follow-up by Pleasantville detectives.The following morning Detective Smith interviewed the suspects separately about the robbery and murder. Detective Smith advised each of the suspects of his rights under Miranda. Both Larry and Moe refused to make any statement (invoking their Fifth Amendment protections) and demanded that they be placed back in their respective cells. Detective Smith called for jail guards to take the suspects back to their cells. As the guards were doing so, they noticed graffiti on the jail cell walls. In Moes cell, the wall read, Sorry God for what I have done, no one was meant to die. In Larrys cell, the wall read, I am innocent of murder, I may be guilty of robbery, but I didnt kill anyone, it was Moe!Larry and Moe are charged criminally for the robbery and murder of the store clerk. During the trial the prosecutor attempts to enter the writings on the jail cell walls as evidence against both defendants. The prosecutor calls the jail guards as witnesses to testify that the graffiti writings were not on the wall prior to Larry and Moe being placed in their individual cells. The attorneys for Larry and Moe object to the writings being admitted as evidence. They base their objection on the fact that each defendant had clearly invoked his Fifth Amendment rights.The judge advises the courtroom that she will need a few minutes to review the defendants objection and orders the court into a thirty-minute recess. Now it is your turn to be the judge. While reviewing defense counsels objection, you must decide the following:1.Should the writings be allowed into the trial as evidence?2.Can Moe's writing be used against him? Why or why not?3.Can Larry's writing be used against him? Why or why not?4.Can Larrys writings be used against Moe? Why or why not?
