Answer:

y=-4, x=8

Step-by-step explanation:

1)3x+5y=4

2)2x+3y=4

Make 1 and 2 have the same co-efficient of x or y (i chose x as it is easier to get to 6 then 15)

Label the 2 new equations as 3 and 4

3)6x+10y=8

4)6x+9y=12

Now we can take away to give

y=-4

Now we substitute this into 1 or 2

I chose 2:

2x+3(-4)=4

2x=4+12

2x=16

x=8

Answer:

x = 8

y = -4

Step-by-step explanation:

Multiply the first equation by 2:

⇒ 3x + 5y = 4  ⇒  6x + 10y = 8

(we will call this equation 3)

Multiply the second equation by 3:

⇒ 2x + 3y = 4  ⇒  6x + 9y = 12

(we will call this equation 4)

Subtract equation 3 from equation 4 to eliminate the x variable:

     6x + 9y = 12

-    6x + 10y = 8

              -y = 4

Therefore, y = -4

Substitute y = -4 into one of the equations and solve for x:

3x + (5 x -4) = 4

⇒ 3x - 20 = 4

⇒ 3x = 24

⇒ x = 8

Answer:

Bill's bar has 57.3 grams of cocoa.

Step-by-step explanation:

The math part that your question is asking is: What is 69% of 83?

In order to use the percent 69% in a calculation, you need to change it to a decimal.

69% is 0.69

You move the decimal to the left, two places.

69% is 69.% If you don't see a decimal to start with and it is a whole number, then the decimal is starting on the right.

Move it two places to the left, you get

.69

Now MULTIPLY.

.69 × 83

= 57.27

ROUND your answer to the nearest tenth. That means only one digit to the right of the decimal.

57.27 rounds to 57.3

Answer:

6.25

Step-by-step explanation:

Using the rules of exponents

[tex](\frac{a}{b}) ^{-\frac{m}{n} }[/tex] = [tex](\frac{b}{a}) ^{\frac{m}{n} }[/tex]

[tex]a^{\frac{m}{n} }[/tex] = [tex](\sqrt[n]{a} )^m[/tex]

Given

[tex](\frac{8}{125}) ^{-\frac{2}{3} }[/tex]

= [tex](\frac{125}{8}) ^{\frac{2}{3} }[/tex]

= [tex](\sqrt[3]{125} )^2[/tex] × [tex]\frac{1}{(\sqrt[3]{8})^2 }[/tex]

= 5² × [tex]\frac{1}{2^2}[/tex]

= 25 × [tex]\frac{1}{4}[/tex]

= [tex]\frac{25}{4}[/tex]

= 6.25

Step-by-step explanation:

Divide 12/14 by 2:

[tex]\frac{12 \div 2}{14 \div 2} =\frac{6}{7}[/tex]

Answer:

D

Step-by-step explanation:

40 is in the same place for B and C, 83 is in the same place for A and C, and 57 is in the same place for A and B.

Triangle D is not similar to the other  three triangle.

Similar triangle may have different sizes but the shape. In similar triangles, corresponding sides are always in the same ratio. The corresponding angles are congruent.

Therefore, triangle A, B and C are similar triangle because the corresponding angles are equal. The angles are 40°, 83° and 57°.

The  last triangle D has a different angles sizes which are 40°, 67° and 73°.

Therefore, triangle D is not similar to the other  three triangle.

Answer:

  (c)  r units right

Step-by-step explanation:

The translation transformations are ...

  g(x) = f(x -h) +k . . . . . . . shifts h units right and k units up

Your transformation has h=r and k=0, so the graph is shifted r units right and no units vertically.

_____

Additional comment

This in not terribly mysterious. Suppose you have f(1) = 6. This means the point (1, 6) is on the graph.

Now, suppose you transform this to ...

  g(x) = f(x -2)

When the value of x is 3, the value of g(x) is f(3-2) = f(1) = 6. That means the point (3, 6) is on the graph of g(x).

It is the same as the point (1, 6) on the graph of f(x), but shifted 2 units to the right.

__

You can shift a function r units right by replacing x with (x-r), as we just discussed. You can shift a function u units up by replacing y with (y-u). When we write equations in "functional form", the "u" gets "moved."

  y-u = f(x) . . . . . graph of f(x) shifted u units up

  y = f(x) +u . . . . graph of f(x) shifted u units up. (u added to both sides of the above equation)

Answer:

Step-by-step explanation:

Dilated by a factor of three means that the two dimensions needed for the are are multiplied by 3.

width = 6*3 = 18

Length = 10 * 3 = 30

Area of dilated rectangle = 18*30 = 540 inches ^2

Answer: 2

Step-by-step explanation:

took the quiz

The length of the sculpture is 2 feet.

Given information about the sculpture:

Width of the sculpture = x feet

Depth of the sculpture = x + 6 feet

Length of the sculpture = 2x - 12 feet

The volume of a rectangular prism is given by the formula:

Volume = length × width × depth

According to the given information, the volume of the sculpture is 26 times its width in linear feet. Therefore, write the equation as:

Volume = 26 × Width

Volume = 26x

Write the expression for the volume of the sculpture using the dimensions:

Volume = (2x - 12) × x × (x + 6)

Set up the equation:

26x = (2x - 12) × x × (x + 6)

26x = (2x² - 12x) × (x + 6)

26x = 2x³ + 12x² - 12x² - 72x

26x = 2x³ - 72x

Now, rearrange the equation to set it equal to zero:

2x³ - 72x - 26x = 0

2x³ - 98x = 0

2x(x² - 49) = 0

2x = 0

x = 0

And, the value of x is calculated as:

x² - 49 = 0

x² = 49

x = ±√49

x = ±7

Since dealing with dimensions, have a negative value for x.

Therefore, x = 7.

The value of x is 7, find the length of the sculpture:

Length = 2x - 12

Length = 2 × 7 - 12

Length = 14 - 12

Length = 2 feet

So, the length of the sculpture is 2 feet.

The probability of rolling a 6 and spinning a vowel is 1/15.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

We have,

A six-sided number cube is rolled, and then a spinner with 5 equal sections labeled A through E is spun.

Outcome for cube rolled = {1, 2, 3, 4, 5, 6}

Outcome spinner spun = {A, B, C, D, E}

So, the probability of rolling a 6 and spinning a vowel
