Answer:

E. the product of seven and the difference of b minus two

Step-by-step explanation:

7(b-2)

seven is being multiplied by the difference of b minus 2

So this can be written as the product of seven and the difference of b minus two.

Reasons its not the other answer choices

A. two subtracted from the quotient of seven divided by b would be (7/b) - 2

B. seven added to difference of b minus two would be 7 + (b-2)

C. the quotient of seven divided by b minus two would be 7/(b-2)

D. two subtracted from seven times b would be 7b - 2

Key Vocabulary:

Difference = Subtraction

Product = Multiplication

Quotient = Division

The product of seven and the difference of b minus 2

First of all the difference of 2 numbers indicates that we subtract these numbers .

For instance , here we subtract :

b - 2

so we have the difference of b minus 2

then the product means we multiply .

For instance , here we multiply 7 times the difference of b and 2 .

A number / variable before the parentheses indicates that we multiply that number times the parentheses .

Answer:

[tex]\displaystyle 3^{12}[/tex]

Step-by-step explanation:

   Using the properties of exponents, when multiplying two exponents of the same base together you can add the powers.

[tex]\displaystyle 3^{4} *3^{8} =3^{4+8} =3^{12}[/tex]

     The expression simplifies too:

             [tex]\displaystyle 3^{12}[/tex]

Answer:

Below!

Step-by-step explanation:

Let us consider that 16 + 4 and 2(2w+8) are equal. Then;

This equation can be solved in two ways. Listed below!

Method 1:

Let's simplify the left-hand-side of the equation.

Then, divide "2" both sides of the equation to open the parentheses.

Subtract 8 to both sides of the equation to isolate the variable (w) and it's coefficient.

Finally, divide 2 to both sides of the equation to isolate the variable (w).

Therefore, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.

Method 2:

Let's simplify the left-hand-side of the equation.

Then, simplify the distributive property to open the parentheses.

Subtract 16 to both sides of the equation to isolate the variable and it's coefficient.

Finally, divide 4 to both sides of the equation to isolate the variable (w).

As said in method 1, 16 + 4 and 2(2w + 8) can be equal if the value of "w" is 1.

Answer:

F. 122º

Step-by-step explanation:

By definition, the sum of 2 supplementary angles is 180º

Hence 58º + x = 180º

x = 180º - 58º - 122º

Answer:

y = -x/5 - 3

Step-by-step explanation:

Slope intercept form: y = mx + b

x + 5y = -15

5y = -15 - x

y = -15/5 -x/5

y = -x/5 - 3

The y intercept is the starting depth of the snow. In this case, it would be 18 inches (aka 1 ft + 6 inches aka 1.5 feet)

The y intercept is the starting value and it occurs when t = 0

S = -2t+18

S = -2(0)+18

S = 0+18

S = 18

At time t = 0, the depth of the snow is S = 18 inches. As t increases, the value of S will decrease.

Answer:

  C.  The equation has two valid solutions

Step-by-step explanation:

A rational equation like this is often solved by "cross-multiplying" to eliminate the fractions. When we do that, we get ...

  4(2x+10) = x(3x+1) . . . . . . . multiply both sides by (3x+1)(2x+10)

  3x² -7x -40 = 0 . . . . . . . . . . rearrange to standard form

  3x² -15x +8x -40 = 0 . . . . . . separate -7 into factors of 3(-40)

  3x(x -5) +8(x -5) = 0 . . . . . factor pairs of terms

  (3x +8)(x -5) = 0 . . . . . . . finish factoring

The zeros of these factors are not zeros of the original denominators, so neither of the solutions these give is extraneous.

  3x +8 = 0   ⇒   x = -8/3

  x -5 = 0   ⇒   x = 5

Step-by-step explanation:

A. f(x) = -16x² +24x + 16

0 = -8(2x² - 3x - 2) ⇒ -8(2x + 1)(x - 2) = 0 ⇒ x = -1/2, 2

B. f'(x) = -32x + 24 ⇒ 0 = -8(4x - 3) ⇒ x = 3/4

f''(x) = -32 ⇒ f''(3/4) = -32 ⇒ concave down ⇒ maximum

f(3/4) = -16(9/16) + 24(3/4) + 16 = -9 + 18 + 16 = 25

By the second derivative test, the point (3/4, 25) is a maximum.

C. 1. Plot the intercepts. 2. Plug in points. 3. Draw the curve.

Answer:

Option B, [tex]x =[/tex] ± [tex]9.49[/tex]

Step-by-step explanation:

Step 1:  Add 90 to both sides

[tex]x^2 - 90 = 0[/tex]

[tex]x^2 - 90 + 90 = 0 + 90[/tex]

[tex]x^2 = 90[/tex]

Step 2:  Square root both sides

[tex]\sqrt{x^2} = \sqrt{90}[/tex]
