Find the value of x and round to the nearest tenth.

Answer:

[tex] {x}^{2} + 6x + 5[/tex]

Step-by-step explanation:

Required polynomial

[tex] {x}^{2} - ( \alpha + \beta )x + \alpha \beta \\ \\ = {x}^{2} - ( - 6)x + 5 \\ \\ = {x}^{2} + 6x + 5[/tex]

Answer:

the first one

Step-by-step explanation:

if you simplify 10/2 it is 5. there is already a 5 as an x value, so that means this isn't a function.

Answer:

[tex] - 14(3a - 4b - 6c - 3)[/tex]

Given:

The dimensions of the square photo are 12'' × 12''.

The frame is 2 inches wider than the photo in both length and width.

To find:

The perimeter of the frame.

Solution:

We have,

Length of the photo = 12 inches

Width of the photo = 12 inches

The frame is 2 inches wider than the photo in both length and width. So,

Length of the frame = 12+2 inches

                                 = 14 inches

Width of the frame  = 12 inches

                                = 14 inches

The perimeter of a square is:

[tex]P=4a[/tex]

Where, a is the side length.

Now, the perimeter of the square frame with side 14 inches is:

[tex]P=4(14)[/tex]

[tex]P=56[/tex]

Therefore, the perimeter of the square frame is 56 inches, Hence, option A is correct.

Answer: 74 degrees and 16 degrees

Step-by-step explanation:

A pair of complementary angles add up to 90 degrees.

If we know that one of the two angles is 58 degrees less than the other, we can solve the algebraic equation: x + (x-58) = 90, where (x) is the measure of the one angle, and (x-58) is the measure of the other angle.

x + x-58 = 90 is the same as 2x -58 = 90.

Adding 58 to both sides gives 2x = 148,

and dividing both sides by two gives x = 74.

We now know that one angle is 74 degrees, and the other angle is (74-58) degrees. This gives two angles of 74 and 16 degrees. They both add up to 90 degrees, so they are complementary angles.

Answer:

n = 4

Step-by-step explanation:

The expression must equal 6. Thus, we can make an equation:

3n - (2 + n) = 6

We distribute the negative and take away the parenthesis:

3n - 2 - n = 6

We combine like terms:

2n - 2 = 6

We add 2 to both sides to isolate n:

2n = 8

We divide each side by 2:

n = 4.

Answer:

0.1

Step-by-step explanation:

If A and B are independent, hence P(A and B) = P(A)P(B)

Given the following

P(A and B) = 0.034

P(A) = 0.34

Required

P(B)

Substitute into the given formula;

P(B) =P(A and B)/P(A)

P(B) = 0.034/0.34

P(B) = 0.1

Hence the value of P(B) is 0.1

Answer:

y = 5x - 1

Step-by-step explanation:

Given the following data;

Intercept = -1

Slope = 5

To find the equation of line;

Equation of straight line is y = mx + c

Where;

m is the slope.

x and y are the points

c is the intercept.

Substituting the values in order to find the intercept, we have;

y = mx + 1

y = 5x - 1

Answer:

C. No solutions exist Because the situation describes two lines that have the same slope and different y-intercepts

Step-by-step explanation:

it is important to keep the x-and y-coordinates in the same order in both the numerator and the denominator otherwise you will get the wrong slope so there is no solution.

Answer:

-5/12

Step-by-step explanation:

2 1/6 -(-1 3/4) =

-13/6 - (-7/4) =

-5/12

-5/12

Step-by-step explanation:

Step 1: Eliminating a negative and changing our operation

−2 1/6 + 1 3/4

Step 2: Rewriting our equation with parts separated

-2 − 1/6 + 1 + 3/4

Step 3: Solving the whole number parts

−2 + 1 = −1

Step 4: Solving the fraction parts

−1/6 + 3/4 = ?

Step 5: Find the LCD of 1/6 and 3/4 and rewrite to solve with the equivalent fractions.

LCD = 12

−2/12 + 9/12 = 7/12

Step 6: Combining the whole and fraction parts

−1 + 7/12 = −5/12
