I Need Help On A Math Assignment.

Answers

Answer 1

Answer:

(18 , - 10)

Step-by-step explanation:

5x + 4y = 50 .... (1)

x + 2y = - 2 ... (2)

Solve (2) for "x"

x = - 2y - 2 .... (3)

(3) ----> (1)

5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ y = - 10 .... (4)

(4) ----> (2)

x + 2(- 10) = - 2 ⇒ x = 18

(18, - 10)

Answer 2
the answer is (18, -7). Hope this helps :)

Answer:

Every five minutes, the shuttle loses 1.6km in altitude. This can be written in the equation y = [tex]\frac{1.4}{-5}[/tex]x + 100.It would have been 100.56 km above the earth. You can do this by plugging in -2 into the equation above. You have to use -2 because it is 2 minutes before tracking started.It will take around 357 minutes for it to reach the ground. Set the equation equal to 0 and solve for x which represents the time taken.

Step-by-step explanation:

1. change in y over change in x.

  [tex]\frac{100-98.6}{0-5}[/tex] = [tex]\frac{1.4}{-5}[/tex]

  This becomes your slope.

   the y-intercept is 100 because at x = 0, y= 100.

   So plug these values into y = mx + b and you get y = [tex]\frac{1.4}{-5}[/tex]x + 100.

2. If the line starts at x = 0, then if you want to get a value for 2 minutes prior           you have to use -2 because 0 - 2 = -2.

   y = [tex]\frac{1.4}{-5}[/tex](-2) + 100

   Set it equal to zero and solve algebraically. The answer should be   100.56.

3. If we want to see how many minutes it takes to get to an altitude of 0, we have to make y = 0  and solve for x. This is because we know that y will be 0 but we don't know how long it takes.

    0 = [tex]\frac{1.4}{-5}[/tex]x + 100

    Solve algebraically and you should get an answer around 357.

Answer:

8.8

Step-by-step explanation:

first set up the equation 2x+10=3x-13

then add 10 to -13 and add 2x to 5x so you get 5x=-3

then divide 5 from both side so you get x=-0.6

now that x=-0.6 you can solve 2x + 10 and that gets you  8.8.

8.8 is the measurement of angle 1 because it is directly opposite to 2x+10

What is 200 plus 200 plus 1,000 plus 6,000 equal to?
After you add those number subtract 1,200

But what 6,000 plus 200 equal??

Answers

Answer:

200+200+1,000+6,000 = 7,400 - 1,200 = 6,200

6,000+200=6,200

Step-by-step explanation:

so 200 plus 200 equal to 400 plus 1,000 equal to 1,400 plus 6,000 equal to 7,400 and then 7,400 subtract by 1,200 equal to 6,200.

and 6,000 plus 200 equal to 6,200.

Which quadrant will be completely shaded by the graph of the inequality y < 3x ?
A.Quadrant I
B. Quadrant II
С. Quadrant III
D. Quadrant IV

Answers

Answer:

D. Quadrant IV

Step-by-step explanation:

At first we need to graph the function [tex]y = 3\cdot x[/tex], whose representation is included in the figure attached below. The positive slope and the y-intercept equal to zero means that the inequality only takes any point below the line into account, that is, it covers Quadrants I and III partially and the Quadrant IV completely. Then, the correct answer is D.

Hyo-Jin makes bracelets and sells them on an online craft website. Last month, she sold 6 bracelets. After paying the website a commission of $1.25 for each bracelet sold, Hyo-Jin made a total of $16.50. How much does each bracelet sell for on the website? Explain the steps you followed to get your answer.

Answers

Answer:Sample response: I set up an equation to show that the number of bracelets multiplied by the cost of each bracelet minus the commission is equal to the total, 6(x – 1.25) = 16.50. I divided each side by 6, then added 1.25 to each side with a result of x = 4. Hyo-Jim sold each bracelet for $4.

Answer:

153

Step-by-step explanation:

Answer:

6,273 ÷ 41 =153

Step-by-step explanation:

simplify by prime factorization 15/27

Answers

[tex]⟹ \: \cancel \frac{15}{27} = (3 \times 3 \times 3 \times 3 \times 3 ) \: (9 \times 9 \times 9)[/tex]

[tex] ⟹ \cancel \frac{15}{27} = 5(3) \times 9(3)[/tex]

[tex]⟹ \cancel \frac{15}{27} = \frac{5}{9} [/tex]

Therefore, when 15/27 is factorise using the method of prime factorization we'll get 5/9.
