A linear system is classified as inconsistent. Choose True or False for the statement about the graph of the system.The slopes of the lines are the same.

Answers

Answer: true

Step-by-step explanation:

A system of linear equations can be written as:

y = a*x + c

y = d*x + f

Now, the idea of this is find the point (x, y) where both linear equations meet.

Particularlly, if the slope in both equations is the same, we will have two options:

1) The lines are parallel, so they never met, and the system has no solution.

2) The lines are the same lines (this happens when c = f) and this means that we have infinite solutions.

So it is true, if the slopes are the same, the linear system is not consisten.

Find the interest on $4,500 at 5.2% for 2 and a half years. Which of the following equations would be used to solve this problem?
Please help!

A: 4500 = P(0.052)(2.5)

B: I = (4500)(5.2)(2.5)

C: I = (4500)(0.052)(2.5)

D: I = (4500)(0.52)(2.5)

Answers

The answer is C: 1=(4500)(0.052

The equations used to solve this problem is I = (4500)(0.052)(2.5).

The correct option is (C).

What is Interest?

Simple interest is a loan interest payment that borrowers pay to lenders. It is based solely on the principal and does not account for compounding interest. Straightforward interest is not limited to certain loans. It is also the form of interest that banks pay on savings accounts.

Given:

P = $4500

R= 5.2%

Time= 2 and half year

Using the formula of Simple Interest

= P x R x T / 100

= (4500 x 5.2 x 2.5)/ 100

= (4500 x 0.052 x 2.5)

= $585

So, the equation is: : I = (4500)(0.052)(2.5)

Whats the area of a square that is 9m and 9m?

Answers

Answer:

81 m².

Step-by-step explanation:

To find the area of a square, you will simply need to do the side-length squared, or [tex]A= l^{2}[/tex].

If the side-length is 9, we can do:

A = 9²

A = 81 m²

Step-by-step explanation:

Step 1:  Find the area

An area of a square has a formula of → [tex]A= s^2[/tex]

[tex]A = 9 * 9[/tex]

[tex]A = 81[/tex]

Answer:  [tex]Area=81m^2[/tex]

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains

pure antifreeze. The company wants to obtain
320

gallons of a mixture that contains
55
%

pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?

Answers

Answer:

let w = amt of water required

:

An equation based on the the percent water, an 80% solution is 20% water.

 

.20(320-w) + w = .50(320)

64 - .2w + w = 160

.8w = 160 - 64

w = 96%2F.8

w = 120 gal of water to produce 320 gal of 50% antifreeze

:

320 - 120 = 200 gal of 80% solution

Water: _120___ gallons

Premium Antifreeze: __200___ gallons

A movie theature offers two containers. One container is a traiangular prism with a base area of 12cm and 19 cm of height, for $6.75. The other is a rectangular prism with a base area of 8cm and a height of 15cm, for $6.25. Which container is the better value? Use 3.14 as an approximation for pie

Answers

Answer:

rectangular container

Step-by-step explanation:

Triangular prism area: A = 1/3 * base area * height

                                        = 1/3 * 12 * 19

                                        = 76 cm²

Rectangular prism: A = base area * height

                                   = 8 * 15

                                   = 120 cm²

The rectangular container has a better value because it has a bigger area and is cheaper.

Maya can run 18 miles in 3 hours, and she can bike 18 miles in 2 hours.
c
Maya biked for 3 hours and then ran for 1 hour and 30 minutes. What distance did she cover?

Answers

Answer:

36

Step-by-step explanation:

if it is two hours then half of it is 9

so 18 + 9 = 27 which is how many miles she biked

6 is the number of miles she ran

so u times it by 1.5

27 + 9 = 36

Answer:

36 miles

Step-by-step explanation:

Her running speed is 6 mph and her biking speed is 9 mph (from part a and b)

she biked for 3 hours so multiply that by 9 (biking speed) to get 27

she also ran for an 1.5 hours so multiply that with 6 (running speed) to get 9

27+9=36

Answers

Answer:

k = 5,

y = 5x

Step-by-step explanation:

If y is proportional to x,

y ∝ x

Then the equation will be

y = kx

Her k = proportionality constant.

Now we choose a point from the given table.

Let the point is (2, 10).

By putting the values of x and y in the equation,

10 = 2×k

k = [tex]\frac{10}{2}[/tex]

k = 5

This will be true for any point we choose from the table.

And the equation will be y = 5x
