Answer 1

Answer:

(I attached an image of the graphed lines)

Step-by-step explanation:

First, we need to graph the original function:

The given equation is written in y=mx+b form, in which m is the slope and b is the y-intercept, or where the line crosses through the y axis. This means the slope is [tex]\frac{2}{1}[/tex] and the y-intercept is -4.

Next, we need to find the inverse of the function and graph that as well:

First, change f(x) in the given equation to y. These mean the same thing, it just makes it easier to work with.Swap the places of x and y. Then, the rest of the steps are essentially just isolating the variable y.Add 4 to both sides of the equation to cancel out the -4 (You will end up with -2y = x + 4)Divide both sides of the equation by -2 to isolate y (You will end up with y = (x/2) + 2)

What is Scale Factor ?

Scale Factor is defined as the ratio of size of new image formed to the size of old image.

We have,

A parallelogram with side lengths [tex]18[/tex] centimeters and [tex]45[/tex] centimeters.

And,

A second parallelogram with side lengths [tex]A[/tex] and [tex]5[/tex] centimeters.

Now,

Scale Factor [tex]=\frac{size\ of\ new\ image}{size\ of\ old\ image}[/tex]

So,

Now, Comparing sides ,

We get,

Scale Factor [tex]=\frac{45}{5}=9[/tex]

i.e. the second parallelogram have Scale Factor of [tex]9[/tex].

So,

Other sides of both parallelograms will be of same Scale Factor.

i.e.

[tex]=\frac{18}{A} =9[/tex]

⇒

[tex]A=2[/tex] cm

Hence, we can say that the length of side A in the new parallelogram will be [tex]2[/tex] cm.

Add these together, and solve for b:

b = 13

Find the weight of Train A by plugging in 13 as b into one of the equations, and solving for a

a + b = 510

a + 13 = 510

a = 497

So, Train A is 497 tons and Train B is 13 tons

HELP IM SO CONFUSED about this

Answers

Answer:

180

straight

Step-by-step explanation:

Hello There

So we are given that angle a is equal to 11x + 37

we are also given that x = 13

because we are given the value of x we can simply find the measure of angle A by plugging in 13 to x into the expression

so basically angle A = 11 ( 13 ) + 37

11 * 13 = 143

143 + 37 = 180

now we want to classify the angle

here are the angle types and what they measure

(let x be measure of angle)

acute 0 < x < 90

so an acute angle has a measure of less than 90 degrees

the measure of angle A is 180 degrees so we can clarify that it is not an acute angle

right angle x = 90

a right angle has a measure of 90 degrees

angle a has a measure of 180 degrees therefore it is not a right angle

obtuse angle 90 < x < 180

the measure of an obtuse angle must be less than 180

because angle a = 180 it is not classified as an obtuse angle

straight angle x = 180

Paul wants to visit his aunt who lives 300 miles away from his house. He drives his car at about 50 miles an hour. If X represents the time spent driving and why represents the distance from his aunts house which scatterplot could represent the situation

Answers

Answer:

It would take 6 hours.

An equation for that could be: 50x = 300 (X is how long it would take)

So 50 mph• X (time spent) = 300 miles

3 5 of the first group are right-handed. 80% of the second group are right-handed. What fraction of the class is right-handed?

Answers

4/5 is right handed in the second group

Answer:

7/10

Step-by-step explanation:

To make things simple, let's turn 80% into a fraction, 8/10. To get a common denominator let's turn 8/10 into 4/5. Since they are both of equal size, the first group would have 2/5 left-handed people and the second 1/5 left-handed people. Let's imagine that each group has 5 people in it. There would be 10 people in total. There is 1 person for each fifth so we can add now. 4 + 3 = 7 right handed people. To check, 2 + 1 = 3 and 3 + 7 = 10. so 7/10 of the class is right-handed.

6/12+8/12+9/12=23/12=1 11/12

Answer:

D. 1 11/12

Step-by-step explanation:

Let's set up our common denominator first. To do this we need to find a number divisible by 2, 3, and 4.

Multiply 3 by 4 and you'll come out with 12. 12 is divisible by 2.

Now, multiply your fractions by the numbers they need to get the denominator to 12.

1/2 x 6/6 = 6/12

2/3 x 4/4 = 8/12

3/4 x 3/3 = 9/12

Add your numerators.

6 + 8 + 9 = 23.

Your fraction should look like 23/12.

Subtract 12 from 23 and you should get 11. Because 12 equals a whole, we can go ahead and put one.
