Answer 1

Answer: the first one we see that the intersection is 3 units to the right and 6 uniits down or x=3 and y=-6 (down=-) so the point is (3,-6)

the solutions (1,2)
we subsitute and find that the answer is the first equation

we add them together and get
we negative the first and add
-2x+2x+y+y=5+5
2y=10
y=10
sutaitute
2x-y=-5
2x-10=-5
we can see that there is 1 solution

Your bank gives you a special loan of $112,000. At the end of 30 years, you will pay the bank $176,400 in simple interest. What is the annual interest rate on your loan?

Answers

In the given problem there are several information's worth taking note of. Based on these information's the rate on the loan can be calculated.It is already given that the Principal amount is $112000. Time is given as 30 years and the final amount as $176400.
Now we have to find the amount of interest first
Interest amount = (176400 - 112000) dollars
   = 64400 dollars
As per the formula of simple interest we know that
Interest = Principal * Rate of interest * Time
Rate of Interest = (Principal * Time)/Interest amount
      = (112000 * 30)/64400
      = 3360000/64400
      = 52.17
So the rate of interest on the loan for the period of 30 years was 52.17%

Factor quadratic equation 6x.squared +41x + 63 = 0

Answers

Answer:

x1= -9/2 ; x2= -7/3

Step-by-step explanation:

Rewrite to 6x^2 + 27x +14x +63 = 0

Factor and get 3x(2x + 9) + 7(2x + 9) = 0

Factor again and get (2x + 9)(3x + 7) = 0

Separate into possible cases -> 2x + 9 = 0; 3x + 7 = 0

The equation has two solutions: x1 = -9/2 and x2 = -7/3

Hope this helped!!

How to find area of square

Answers

To find the area of a square, remember that a square is a type of rectangle so we can use the following formula to find its area.

Area = length × width

However, since the length and width of a square are always equal, we use a special version of this formula to find the area of a square.

Instead of area = length × width, we say that the area of a square is equal to side × side or s².

I'll show an example.

Image provided.

Since each side of a square is the same, it can simply be the length of one side squared. So multiply the sides by one another say your square had a length of 10 and to find the area multiply the other side length since all squares mostly have the same side length multiply it by ten again and you get 100.

Please help me!!!!!!!!!!!!!!!!!!!!!Arusha draws a rectangular prism that is made up of two connected cubes, each with side length e. The surface area of a certain rectangular prism with
edge length is represented by the formula SA= 10e ^{2} , and the volume of the prism is represented by the formula V= 2e ^{3} .

Part A- What is the surface area of the prism if its edge length is 5 cm? Show work

Part B- Arusha plans to build the prism and partially fill it with 150 cubic centimeters of sand. What fraction of the prism's volume will be filled by the sand? Show Work.

Answers

The SA would be 10e² because there are 10 squares.
The V would be 2e³ because there are 2 cubes.

Part A
If e = 5 cm, simply plug it into the SA formula we have already.
SA = 10e² = 10*5² = 10*25 = 250 cm².

Part B
If e = 5cm, simply plug it into the V formula we have already.
V = 2e³ = 2*5³ = 2*125 = 250 cm³.

Now we need to find what percent of 250 is 150?

250p = 150
p = 150/250 = 3/5 = 0.6 = 60%
