answer is : -24

need an explanation?
- step one :
for the first equation
given that x=-10
f(x) =2x-4 if 3x exists in this domain
substituting x in the equation we have
f(-10)=2(-10)-4
f(-10)= -20-4
f(-10)=-24

step two :
for the second equation

A hybrid SUV can travel 400 miles on a 15-gallon tank of gas. How many miles can it travel on 6 gallons of gas?

Answers

Answer:

160miles

Step-by-step explanation:

400miles uses15g what about 6g.

Using cross multiplication. Multiply 6x400/15 = 160miles

Answer:

160 miles

Step-by-step explanation:

If it travels 400 miles on 15 gallons, then it will travel x miles on 6 gallons

400 miles -> 15 gallons

x miles -> 6 gallons

15 * x = 6 * 400

15x = 2400

x = 2400 / 15

x = 160 miles

Choose the correct algebraic equation to represent: the amount decreased by $9 is $42.
Giving brainlist please help!


9 - m

9 – m = 42

m - 9

m – 9 = 42

Answers

m - 9 = 42

42 is our final answer so that should be by itself.

If something is being decreased by 9, that means that we are taking away 9 from something so it should be m - 9.

Answer:

m-9=42

Step-by-step explanation:

I'm pretty sure that m-9=42 is the correct answer because m or the amount is being decreased by 9 as 9 is being subtracted from it.

Answers

Answer:

1:4

Step-by-step explanation:

Given

3: 12

To express in the form 1:n

Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3

3:12

= 3/3:12/3

= 1:4

Comparing with 1:n, it is safe to say that n = 4

PLEASE HELP ASAP!! Students take a test worth a total of 100 points. There are 24 questions on this test, some are worth 5 points and others are worth 3. Solve for how many 5 point questions and 3 point questions there are on the test

Answers

Answer:

There are 14 5-point questions and 10 3-point questions.

Step-by-step explanation:

Form 2 equations:

Let x= 5-point questions

Let y= 3-point questions

1.) x+y=24

2.) 5x+3y=100

Use substitution by reforming equation 1 in terms of x or y (I used y)

1.) y=24-x

Sooo, substitute this into the y in the 2nd equation:

5x+3(24-x)=100

5x+72-3x=100

2x=100-72

2x=28

x=14

Now that we have x, substitute this into the 1st equation to get y:

1.) y=24-x

y=24-14

y=10

In conclusion, there are 14 5-point questions and 10 3-point questions.

Answer:

There are 14 questions that are worth 5 points and there are 10 questions that are worth 3.

Step-by-step explanation:

14 x 5 = 70

10 x 3 = 30

70 + 30 = 100

14 + 10 = 24 questions total

x-4=-x+2

Add x on both sides

x-4+x=-x+2+x

2x-4=2

Add 4 on both sides

2x-4+4=2+4

2x=6

Divide 2 on both sides

2x/2=6/2

x=3

In the figure, BC is a support for the roof
of a garage. What is the length of BC?

Answers

Answer:

Bc = √63 ft

Step-by-step explanation:

Here, we want to get the length of BC

As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side

So we want to get the third leg which is BC

we can use the Pythagoras’ theorem here

And that states that the square of the hypotenuse equals the sum of the squares of the two other sides

let the missing length be x

12^2 = x^2 + 9^2

144 = x^2 + 81

x^2 = 144-81

x^2 = 63

x = √63 ft

13. L'Shonda purchased a container of juice that contains 200 calories. The label says that 40% of the calories are from carbohydrates. How many calories are from carbohydrates? ​

Answers

Answer:

80

Step-by-step explanation:

So I here's my thought process on this:

200 divided by 2 is 100

100 - 40% is 60, leaving 40 behind.

So double that and it would be:

200 - 40% is 120

200 - 120 = 80

80% is the answer.
