[tex](x - y) ^{2}[/tex] + ([tex]x^{2}[/tex] + 2xy + [tex]y^{2}[/tex])

(x - y) (x - y) + ([tex]x^{2}[/tex] + 2xy + [tex]y^{2}[/tex])

[tex]x^{2}[/tex] + [tex]y^{2}[/tex] - xy -xy + ([tex]x^{2}[/tex] + 2xy + [tex]y^{2}[/tex])

[tex]x^{2}[/tex] + [tex]y^{2}[/tex] -2xy + ([tex]x^{2}[/tex] + 2xy + [tex]y^{2}[/tex])

[tex]x^{2}[/tex] + [tex]y^{2}[/tex] -2xy + [tex]x^{2}[/tex] + 2xy + [tex]y^{2}[/tex]

[tex]x^{2}[/tex] + [tex]y^{2}[/tex]  + [tex]x^{2}[/tex]  + [tex]y^{2}[/tex]

Answer:

x = 2

Step-by-step explanation:

f(x) = x + 8

f(x) = 10

10 = x + 8

minus 8 from the both sides

10 - 8 = x

2 = x

Answer: $109.99

Step-by-step explanation:

The total amount saved, $96.16, should be divided by the number of tires, 4. The answer is $24.04. Add $24.04 to the price of a single tire, $85.95, and the answer is $109.99, the original price of one tire.

Answer:

55% are women

Step-by-step explanation:

27÷60= 0.45

0.45x100=45

100-45=55

45% men

55% women

There are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

A manufacturing plant has 60 supervisors. If 27 of the supervisors are men.

The number of women = 60 – 27 = 33

The percent of women = (33/60)×100

= 0.55×100

= 55%

Thus, there are 55% are women if the manufacturing plant has 60 supervisors. If 27 of the supervisors are men, option third is correct.

Answer:

F. [tex] \frac{3}{4} [/tex]

Step-by-step explanation:

Constant of proportionality, k, = [tex] \frac{y}{x} [/tex]

The ratio of each given of values on the table will give you the same value, which represents k.

Thus, using the pair, (2, 1.5), k can be calculated as follows:

[tex] k = \frac{y}{x} = \frac{1.5}{2} [/tex]

Multiply the numerator band denominator by 10 to eliminate the decimal point.

[tex] = \frac{1.5*10}{2*10} = \frac{15}{20} [/tex]

Simplify

[tex] k = \frac{3}{4} [/tex]

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

The slope of the line that passes through the points (-2, 12) and (4, -15) is -27/6

The y-intercept of the line that passes through the points (-2, 12) and (4, -15) is 3

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The equation of a line is y = mx + c.

The slope can be calculated.

Slope = (d - b) / )(c - a)

Where (a, b) and (c, d) are the two points on the line.

The line passes through (-2, 12) and (4, -15)
This means,

Slope = (-15 - 12) / (4 + 2) = -27 / 6

m = -27/6

The line passes through the point (-2, 12).

12 = -27/6 x -2 + c

12 = 9 + c

c = 12 - 9

c = 3

Thus,

The slope of the line that passes through the points (-2, 12) and (4, -15) is -27/6

The y-intercept of the line that passes through the points (-2, 12) and (4, -15) is 3

Answer:

h = 5.42

r = 5.42

Step-by-step explanation:

Find h with respect to r:

V = πr²h = 500

h = 500/πr²

Plug this into the surface area equation:

SA = πr² + 2πrh

= πr² + 2πr(500/πr²)

= πr² + 1000/r

Differentiate and set to 0, solve for r:

dSA/dr = 2πr - 1000/r² = 0

2πr = 1000/r²

r³ = 500/π

r = (500/π)^1/3

≈ 5.42 cm

find h:

h = 500/πr²

= 500/[π(5.42)²]

= 5.42cm

Alonso brings $21 to the market to buy eggs and avocados. He gets eggs that cost $2.50. Then he notices that the store only sells avocados in bags of 3 for $5. He wants to buy as many avocados as he can with his remaining money. What is the largest number of avocados that Alonso can afford?

9 avocados

$21.00 - $2.50 = $18.50

3 × $5.00 = $15.00

$18.50 - $15.00 = $3.50

$15 = 3 bags of avocados  =  3 bags × 3 avocados = 9 avocados

Answer:

d Geometric sequence; common ratio is −2

Step-by-step explanation:

Identifying Sequences

There are two possible types of sequences to choose from, Arithmetic and Geometric.

The arithmetic sequences are identified because each term is obtained by adding or subtracting a fixed number to the previous term. This number is called the common difference.

In the geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

The given sequence is:

48, -96, 192, -384, 768,....

To identify the type of sequence, we could try subtracting the second term from the first, the third from the second, etc. If those differences were constant, it would be an arithmetic sequence.

In this case, it's not necessary because the sign of the terms is alternating. It can only be possible with geometric sequences with a negative common ratio.

Dividing the second by the first term:

r = -96 / 48 = -2

Dividing the third by the second term:

r = 192 / -96 = -2

The rest of the divisions of successive terms lead to the same common ratio, thus, the answer is:
