Answer:

A = -4

B = 12

Step-by-step explanation:

A is -4 because 8 - 4 is 2. B is 12 because both of the denominators are 12 so the answer's denominator should also be 12.

Hope it helps!

Answer:

r = 1 , 0

Step-by-step explanation:

-7[tex]r^{2}[/tex] + 7r + 2 = 2

-7r(r-1)=2-2

-7r(r-1)=0

r-1=0

r=1

Answer:

  C.  Reflecting over the y-axis and then translating to the right 8 units

Step-by-step explanation:

Reflection over the line x=4 gives you the transformation ...

  (x, y) ⇒ (2·4 -x, y) = (-x +8, y)

This is precisely the same transformation you get by reflection over the y-axis:

  (x, y) ⇒ (-x, y)

followed by translation to the right 8 units:

  (-x, y) ⇒ (-x +8, y)

__

Reflection over x=4 is the same as reflection over y and translation right 8.

Answer:

The 4 in the hundreds place has a value 10 times as great as the 4 in the tens place.

Step-by-step explanation:

440 = 400 + 40 + 0

the hundreds place is worth 400 here

it is worth 10x the tens place (40 here)

Answer:

5x - 4

Step-by-step explanation:

In this question, you have to simplify the expression.

Solve:

2(x + 4) + 3(x - 4)

Use the distributive property.

2x + 8 + 3(x - 4)

2x + 8 + 3x - 12

Combine like terms.

5x + 8 - 12

5x - 4

Since there is no more similar terms, we are left with our final answer.

Your answer would be 5x - 4

Answer:

Angle ABC and angle DEF are supplementary if and only if they add up to 180 degrees

Answer:

half flyfkycoyfkgflycj hrxhrhddzg

∠1 + ∠3 + 90° = 180°

∠1 + ∠3 = 90°

∠3 = ∠4 (vertically opposite angles)

∠1 + ∠4 = 90°

Therefore, the answer is ∠1 + ∠4

Answer:

Step-by-step explanation:

Answer:

$15 dollars

Step-by-step explanation:

We know that Jen sells flowers. We also know that she charges $2 dollar per flower plus a $3 dollar delivery fee.

The question is asking how much will Jen make if she sells 6 flowers. Since every flower costs 2 dollars, we can multiply the cost and amount.

6 * 2

12.

Jen makes 12 dollars just by the flower, and now the delivery fee which is an extra 3 dollars.

12 + 3

$15

Answer:

D

Step-by-step explanation:

The amount of oil and natural gas a given region produces is not always proportionate to the size of its proven reserves. For example, the Middle East contains approximately 50 percent of the world’s proven reserves but accounts for only about 30 percent of global oil production (though this figure is still higher than in any other region). The United States, by contrast, lays claim to less than 2 percent of the world’s proven reserves but produces roughly 16 percent of the world’s oil.

Answer:

[tex]x = 3.5[/tex]

Step-by-step explanation:

Given

Attached Triangle

Required

Find x

To solve for x, we make use of the following equivalent ratios:

[tex]CB : BA = ED : DA[/tex]

Where:

[tex]CB = 2[/tex]

[tex]BA = 4[/tex]

[tex]ED = x[/tex]

[tex]DA = 3 + 4 = 7[/tex]

So, the expression becomes:

[tex]CB : BA = ED : DA[/tex]

[tex]2 : 4 = x : 7[/tex]

Express as fraction

[tex]\frac{2 }{ 4} = \frac{x }{ 7}[/tex]

Multiply both sides by 7

[tex]7*\frac{2 }{ 4} = \frac{x }{ 7}*7[/tex]

[tex]7*\frac{2 }{ 4} = x[/tex]

[tex]\frac{7*2 }{ 4} = x[/tex]

[tex]\frac{14}{4} = x[/tex]

[tex]3.5 = x[/tex]

[tex]x = 3.5[/tex]
