Answer:

See attached image

Step-by-step explanation:

Use the FOIL method

First - multiply the first numbers inside the parentheses (y^2 and -2y)

Outer- multiply the first and last numbers inside the parentheses (y^2 and 7)

Inner - multiply the two numbers next to the closing and opening parentheses (6 and -2y)

Last- multiply the last two numbers in the parentheses. (6 and 7)

Then simplify to put it in standard form.

how do you find the y-intercept?​

Answers

Answer:

The equation of any straight line, called a linear equation, can be written as:   y = mx + b, where m is the slope of the line and b is the y-intercept.               The y-intercept of this line is the value of y at the point where the line crosses the y axis.

so to find that you can use y=mx+b, or you can use point slope form and that would be y-y1+m(x-x1)

remember m= slope b= y- intercept

A company has two manufacturing plants with daily production levels of 7x + 19 items and 2x - 7 items, respectively. The first plant production how many more items daily than the second plant? The first plant produces __? More items daily than the second plant.

Answers

Answer:

The first plant produces 5x + 26 more items daily than the second plant

Step-by-step explanation:

First plant = 7x + 19

Second plant = 2x - 7

The first plant production how many more items daily than the second plant?

Subtract items produced by the second plant from items produced by the first plant

= 7x + 19 - (2x - 7)

= 7x + 19 - 2x + 7

= 5x + 26

The first plant produces 5x + 26 more items daily than the second plant.

Choose all answers that apply:

Step-by-step explanation:

translating the decimal -0.625 to fraction form, you get -5/8, which is equal to B. C is greater, being closer to 0 than -0.625, so that leaves you with A, which is -1.6, and less than -0.625.

what numbers must be added to complete the perfect square?​

Answers

Answer:

256

Step-by-step explanation:

Let the number be k

Thus, the equation can be written as:

x² – 32x + k

From the above,

a = 1

b = –32

c = k

The value of k can be obtained as follow:

b² = 4ac

(–32)² = 4 × 1 × k

1024 = 4k

Divide both side by 4

k = 1024 / 4

k = 256

Thus, 256 should be added to x² – 32x to make it a perfect square i.e

x² – 32x + 256

****Check****

x² – 32x + k

k = 256

x² – 32x + 256

x² – 16x – 16x + 256

Find the equation of the line that is perpendicular to y = -2x+ 6 and passes though the point (-4,2).

Answers

Answer:

y= 1/2x + 6

Step-by-step explanation:

when making a perpendicular equation, flip the slope.

Answer:

y = 1/2x + 4

Step-by-step explanation:

The slope of the perpendicular line will have the complete opposite slope.

The perpendicular slope is 1/2x.

To get the slope I just got the opposite sign and reciprocal of -2.

NOW plug in (-4,2) to find the y-intercept

2 = 1/2(-4) + b (b represents y-intercept)

2 = -2 + b (add 2 on both sides)

4 = b

y = 1/2x + 4 is the final equation

The length of a rectangle is twice its width, while the
perimeter of the rectangle is 36 units. . Which system of
equations can be used to find the length ( and the width w
of the rectangle?

Answers

Answer: Length = 12 units

Width = 6 units

Step-by-step explanation:

Let the width of the rectangle be represented by x.

Since the length of a rectangle is twice its width, thus means that the length will be: = 2x

Perimeter of a rectangle = 2(l + w)

where,

L = length

W = width

Therefore,

Perimeter = 2(l + b)

36 = 2(2x + x)

36 = 2(3x)

36 = 6x

x = 36/6

x = 6

Width = 6 units

Length = 2 × Width = 2 × 6 = 12 units

Marcus has a summer job where he makes $45 per day. Yesterday his boss told him he was getting a raise to $63 per day because he was such a hard worker. What is the percent increase in Marcus' salary? Write a number answer without a dollar sign.

Answers

Answer:

40% increase

Step-by-step explanation:

63/45 = 1.4 = 140%

63 is 140% of 45 meaning it is a 40% increase

The percent increase in Marcus' salary is 40% as per percentage calculation.

What is percentage calculation?

"Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. The formula used to calculate percentage is: (value/total value)×100%."

Given, Marcus has a current job that pays $45 per day.

From yesterday, he is getting $63 per day.

Therefore, the increase in daily salary = $(63-45) = $18.

Therefore, the percentage increase of his daily salary = (18/45) × 100 = 40%.
