Select all equations that have graphs with the same y-intercept.

Select all that apply:
A) y = 3x - 8
B) y = 3x - 9
C) y = 3x + 8
D) y = 5x - 8
E) y = 2x - 8
F) y = (1/3)x - 8

Answers

Answer: A, C, D, E, and F have the same y-intercepts.

Step-by-step explanation:

The Equation for graph A has a y-intercept of -8

The Equation  for graph B has a y=intercept of -9

The Equation for graph C has a y-intercept of -8  

The Equation for graph D has a y-intercept of -8  

The Equation for graph E has a y-intercept of -8

The Equation for graph F has a y-intercept of -8  

The only difference between the y-intercepts of the equations  is the equation for graph B, it has a y-intercept of -9 so it will not be the same as the other equations with the same y-intercepts. \

A, C, D, E, and F have the same y-intercepts.

In which equation would you multiply both sides by 4.5 to get the variable alone?
A. 6.1p = 4.5
B. p ÷ 6.1 = 4.5
C. p ÷ 4.5 = 6.1
D. 4.5p = 6.1

Answers

Answer:

c.

Step-by-step explanation:

p/4.5 = 6.1

to isolate the variable do the opposite action

p/4.5 = 6.1

as p is divided by 4.5, you must multiply both sides by 4.5

p/4.5 ×4.5 = 6.1 × 4.5

p = 27.45

Water is a very cohesive substance. This means that water particles

A.
are repelled by other types of particles.
B.
are repelled by other water particles.
C.
are attracted to other water particles.
D.
are attracted to other types of particles.

Answers

Answer:

C. The charges of the atoms that make up a water molecule makes them attracted to other water particles

The correct option is water particles are attracted to other water particles.

What is cohesive force?

The term "cohesive forces" is a generic term for the collective intermolecular forces responsible for the bulk property of liquids resisting separation.

Specifically, these attractive forces exist between molecules of the same substance.

Given that, the water is a very cohesive substance.

We know that, the cohesive substance attracts the molecules of same kinds,

Cohesion means the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces because of their ability to form hydrogen bonds with one another.

Therefore,

The charges of the atoms that make up a water molecule makes them attracted to other water particles.

Hence, the correct option is water particles are attracted to other water particles.

Answers

300=2×2×5×5×3

We observe that 2 and 5 are grouped in pairs and the 3 is left unpaired.

If we multiply 300 by the factor 3 then  

300×3=2×2×5×5×3×3

900=2×2×5×5×3×3 which is a perfect square.

A mover is loading an elevator with many identical 48-pound boxes.
The mover weighs 185 pounds. The elevator can carry at most 2000 pounds.
Write an inequality that says that the mover will not overload the elevator on a particular ride.

a. Solve your inequality and explain what the solution means.

b. Graph the solution to your inequality on a number line.

Answers

Answer:

b

Step-by-step explanation:

a) After solving inequality , we get x ≤ 37.81 which meant number of boxes must be less than or equal to 38 approximately.

b) The graph is attached below.

What are inequalities ?

When two values are compared , an inequality represents whether one is greater than, less than, or not equal to the other.

It is given that the elevator can carry at most 2000 pounds of load. The weight of mover is 185 pounds. Also a mover is loading an elevator with many identical 48-pound boxes.

a)

Let's assume that the number of boxes is x.

Then the inequality can be written as :

48 × x + 185 ≤ 2000

Solving the inequality to get the value of x :

48x ≤ 2000 - 185

48x ≤ 1815

x ≤ 38 (approximate)

It meant

b) The graph for inequality which is 48 × x + 185 ≤ 2000 or say x ≤ 38 is shown below.

Therefore , the answers are :

a) After solving inequality we get x ≤ 37.81 which meant number of boxes must be less than or equal to 38 approximately.

b) The graph is attached below.

Step-by-step explanation:

Algebra question I don’t get it because you usually have to multiple A by C but there is no C in the problem.

Answers

Ok so basically, when you say multiply A by C, that is simplifying.

And in this case, you are factorising in this question. You turn back into brackets basically.

We have:
72x^2 - 32

x^2 = x squared

factorising means finding the factor of.

(Forget the x squared for the moment to make life easier)

Factors of 72:
1 and 72
2 and 36
3 and 24
4 and 18
6 and 12
8 and 9
(9 and 8 = it repeats so we stop there)

And then factors of 32:
1 and 32
2 and 16
4 and 8
(8 and 4 = repeats so we stop there)

Notice how we see 8 twice in both factors of 72 and 32, this means that we use 8 as the main number we are going to multiply each of the 2 numbers in the brackets by. This is because it is the biggest common factor - this is what we have!

This is what we would have:
8(9-4)

BUT, that is not the answer!
Keep in mind we have the x squared too

But, 32 doesn’t have it?!!

It would be:
8(9x^2 - 4)

Do you get it??

Try to simplify it! Does it equal to 72x^2 - 32?

(And I am so very sorry for the long explanation, once you get the hang of it, it makes sense. Hope my explanation helped) :)

The answer is 18.6. The double negative (minus a negative) equals a positive. So you add 14.3 + 4.3 = 18.6
14.3 - (-4.3). the negative will turn into a plus sign since a minus a negative will be positive. so, 14.3 + 4.3 = 18.6!
