1. Which equation represents a line that passes through the point (-2,6) and is parallel to the line whose equation is 8x – 4y = 6?

Answer:

3. 45, 4. 24

Step-by-step explanation:

use formula: hypotenuse²= side² + other side ²

3.

x²= 27²+36² calculate the squares then add

x²=2025 square root both sides

x= √2025= 45

4.

25²= x²+7² isolate the vaiable by subtracting 7² from both sides

25²-7² = x² square then subtract

576 =x² square root both sides

24=x

Answer:

180 students brought their lunch to school on Thursday

Step-by-step explanation:

We are told that out of 900, 5% of the students brought their lunch to school everyday

So the number that brought their lunch on Thursday will be;

5% of 900

= 5/100 * 900 = 180

Answer:15

Step-by-step explanation:

Answer:

w=35, L = 17

Step-by-step explanation:

the perimeter is all sides added together to total 104. so,

2L + 2W= 104

the width is one more than twice it's length, so W = 2L + 1

plug that into first equation.

2L + 2(2L+1)=104

distribute:. 2L + 4L + 2= 104 and continue to solve for L

6L + 2= 104 subtract 2 from both sides.

6L = 102, divide both sides by 6

L = 17. so the length is 17 ft. now use that number to put it in our equation for width, W= 2L + 1

W= 2(17)+1

W = 35

Answer:

A (-5)

Step-by-step explanation:

The formula for slope is (y2-y1)/(x2-x1). Therefore, to find the slope for this problem, plug the numbers into the formula: (2-(-3))/(-2-(-1)) or (2+3)/(-2+1).

Answer:

B. (2,8), because both equations intersect at this point

Answer:

B. (2,8), because both equations intersect at this point

Step-by-step explanation:

Why is it answer B? Because of Enlarging the graph, we find that the intersection of the two lines drawn is at point (2,8). Hence, the solution of the equation is (2,8) because the graphs of the two lines intersect at this point.

Answer:

Step-by-step explanation:

The standard equation of a line in point-slope form is expressed as;

y-y0 = m(x-x0) where:

m is the slope

b is the y-intercept.

Given the following

Slope = 1/4

(x0, y0) = (-2, -2)

The equation becomes;

y-(-2) = 1/2(x-(-2))

y+2 = 1/2(x+2)

2(y+2) = x+2

2y+4 = x+ 2

2y-x = 2-4

2y-x = -2

For the line through the point (2, 0) with a slope of 1/4

y - 0 = 1/4(x-2)

y = 1/4(x-2)

4y = x- 2

4y - x = -2

Answer:

This is an Equilateral Acute triangle.

The initial amount this student is paid is 0 and this can be determined by using the two-point slope form of the line.

Given :

The given table represents the number of hours a student worked and the amount of money the student earned.

The following steps can be used in order to determine the initial amount this student is paid:

Step 1 - The two-point form of the line can be used in order to determine the initial amount this student is paid.

Step 2 - So, the linear equation that represents the given situation is:

[tex]\rm \dfrac{d-50}{h-8}=\dfrac{93.75-50}{15-8}[/tex]

Step 3 - Simplify the above expression.

[tex]\rm \dfrac{d-50}{h-8}=6.25[/tex]

d - 50 = 6.25h - 50

d = 6.25h

Step 4 - Now, substitute the value of (h = 0) in the above expression.

d = 0

Therefore, the correct option is D) There is no base pay.

Answer:

  A, B, C, D, F . . . as written

Step-by-step explanation:

Any mixed number, fraction, or finite or repeating decimal is rational. The only one in your list that is irrational is E, which appears to be a non-repeating, non-terminating decimal.

__

Your B selection appears to be 11² = 121, an integer and a rational number.

If your B selection is supposed to be √11, then that number is irrational, as it is not the root of a perfect square.

E is irrational; B is rational as written, but irrational if it should be √11. All the others are rational.

Answer:

y = 50x + 26.50

Answer:

Y = $50x + $26.50

Step-by-step explanation:

$26.50 is the independent cost unaffected by hours put in.

Rate is $50 per hour.

X then is the hour count.

Thus,

Y = $50x + $26.50

Answer:

127 per day

Step-by-step explanation:

Total pushups in 4 weeks = 3,556

4-week period( 7 days a week) = 4 × 7

= 28 days

How many push-ups did Joey do each day?

Push ups per day = Total push ups / Total number of days

= 3,556 / 28

= 127

Push ups per day = 127

Joey did 127 push-ups each day for a 4-week period( 7 days a week)

Answer:

the correct answer

x = 6

Step-by-step explanation:

5x+4x-68=34-8x, combine like terms

9x-68=34-8x, add 68 to both sides

9x=102-8x, add 8x to both sides

17x=102, divide both sides by 17

x=6

your friend's answer is the same work, but instead of adding 68 to both sides, it was subtracted from 34 giving a -34 instead of 102.

9x=-34-8x

17x= -34

x = -2
