Solve the system by substitution.
y = 5x
y = 9x + 4

Answers

Answer:

(-1, -5)

Step-by-step explanation:

[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]

1. We must calculate x, for that we must substitute y, so we have:

5x=9x+4

2. Now we solve the equation.

5x-9x=4

-4x=4

x=-1

3. Now we must calculate y

y=5x

y=5(-1)

y=-5

And the answer is (-1, -5)

Answers

Answer:

Step-by-step explanation:

1a. 2x - 4y = 2

   -x  + 4y = 3

x = 5

-5 + 4y = 3

4y = 8

y = 2

(5, 2)

1b. 2x + 3y=1

     -2x + 2y = -6

      5y = -5

       y = -1

     2x - 3 = 1

    2x = 4

    x = 2

   (2, -1)

2a.  x + 2y = 4

       2x - 5y = -1

     -2x - 4y = -8

      2x -  5y = -1

    -9y = -9

      y= 1

2x - 5 = -1

 2x = 4

  x = 2

(2, 1)

2b. 4x + 2y = 4

       x - 2y = -5

       5x = -1

        x= -1/5

    -1/5 - 2y = -5

    -2y = -4 4/5

      y= 12/5

(-1/5, 12/5)

3. 5x + 3y = 85

  11x + 5y = 163

25x + 15y = 425

-33x - 15y = -489

 -8x = -64

x = 8 regular

5(8) + 3y = 85

40 + 3y = 85

3y = 45

y = 15 mini bouquets    

(8 regular, 15 mini bouquets)

4a. 6x + 12y = -6

     18x - 12y = - 162

24x = -168

x = -7

3(-7) - 2y = -27

-21 - 2y = -27

-2y = -6

y= 3

(-7, 3)

4b. 3(6 -y) - 2y = 38

     18 - 3y - 2y = 38

     18 - 5y = 38

    -5y = 20

    y = -4

A company makes steel rods shaped like cylinders. Each rod has a diameter of 8 centimeters and a height of 20 centimeters. If the company used 28,134.4 cm3 of steel, how many rods did it make?

Answers

Answer:

1,172.3 cm³

Step-by-step explanation:

Find the volume of one rod, then divide the total volume of steel used by the volume of one rod.  The volume of one rod is

V = (πd²/4)h

d = 4 cm

h = 20 cm

Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V.  If the result is not an integer, then round down.

Add

20 + 4 = 24

Then

28,134.4 ÷ 24 = 1172.26

Rounded to the nearest 0.1 or  the Tenths Place = 1,172.3

Therefore, 1,172.3 rods will be made per hour.

16 ÷ 22 + (6 x 2) - 8

Answers

I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72
16 ÷ 22 + (6 x 2) - 8 = 4.72

Solve for x. −12x+13>35 Drag and drop a number or symbol into each box to correctly complete the solution.

Answers

Answer:

x < -11/6.

Step-by-step explanation:

−12x + 13 > 35

-12x > 35 - 13

-12x > 22

Divide both sides by -12 and invert the inequality sign:

x < -22/12

x < -11/6.

The ratio of the measure of the three angles of a triangle is 3:4:8. Find the mesure of the large angle

Answers

Answer:

96°

Step-by-step explanation:

Ratio of angles :

3 : 4 : 8

Sum of angles in a triangle = 180°

The value of the largest angle = angle with the largest ratio

This is the value of the angle with ratio 8

Sum of ratio : (3 + 4 + 8) = 15

Hence,

(8 / 15) * 180°

(8 * 180°) / 15

1440 / 15

= 96°
