PLS HELP ME NOW!! 55 POINTS!

There are no answer choices, so I will just list a few. But first, we need to create the equation.

Plugging in (5,7) into the equation y=mx+b, we can solve for b since all of the other variables are known, with m=3 as the slope.

So, 7=3*5+b

7=15+b

b = -8

y=3x-8 is your equation.

So, you can plug in any value of x you get a certain value of y.

(1,-5), (2,-2), (3,1), (4,4), (5,7), (6,10), (7,13)

Answer:

(6, 10)

Step-by-step explanation:

slope = [tex]\frac{change in y}{change in x}[/tex] = [tex]\frac{3}{1}[/tex]

to find another point on the line add 3 to the y-coordinate and add 1 to the x-coordinate

(5, 7) → (5 + 1, 7 + 3) → (6, 10) ← other point on line

continue to do this for other points

(6, 10) → (6 + 1, 10 + 3) → (7, 13)

Answer:

y = 3x-3

Step-by-step explanation:

y = mx+b

m is your slope and b is your y-intercept

plug those numbers in

y = 3x-3

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

We have m = 3 and b = -3. Substitute:

Answer: False

A plane is a flat line that extends forever in all directions. Think of a flat piece of paper that does not bend or curve. If you intersect two planes, then they will form a straight line. This line will extend forever both directions. There are infinitely many points on this line of intersection. You can think of a book as a good example: the pages are the planes while the spine is the line of intersection.

Answer:

The image with 25, 144 and 169 represents proof of the Pythagorean Theorem.  

Step-by-step explanation:

The Pythagorean Theorem is used to find the missing side of a right triangle.  The formula is a^2 + b^2 = c^2, where 'a' and 'b' represent the legs of the triangle (the ones the form the 90 degree angle) and 'c' represents the hypotenuse (the diagonal across from the 90 degree angle).  In the case of the three squares, the area of each square is given.  The area of a square is simply the base multiplied by the height, which in the case of a square those dimensions are the same.  So, taking the square root of 25 = 5, the square root of 144 =12 and the square root of 169 = 13.  If we apply the Pythagorean Theorem formula, we get 5^2 + 12^2 = 13^2, or 25 + 144 = 169.  This image proves the Pythagorean Theorem holds true.

Answer: 90

Step-by-step explanation:because  if you times 10 to get 30 so you also times it by 9 so 9 x 10 = 90

The equation of the given straight line in slope-intercept form is y = 3x + 9. The y-intercept or the point at which the line crosses the y-axis (0,9), and the rate of change or slope of the line is 3.

The equation of a line in slope-intercept form is expressed as y = mx + b where m represents the slope of the line, and b represents the y-intercept.

Given the information from the figure, the slope m is 3 and the y-intercept b is 9. Therefore, the equation of the line in slope-intercept form can be written as y = 3x + 9.

The line intersects the y-axis at (0,9) which is the y-intercept in coordinate form. The rate of change, represented by the slope, is 3, which means for every increase of 1 unit on the x-axis, the y-value increases by 3 units.

Answer:

Russell:  40 pounds; Sarah:  100 pounds; and Terry:  160 pounds.

Step-by-step explanation:

The three different amounts of money are 2x, 5x and 8x, or 15x.

Terry gets 8x, whereas Russell gets 2x, and 8x - 2x = 120 pounds.

Solving for x, 6x = 120 pounds, and so x = 20 pounds.

Russell gets 2(20 pounds);  Sarah gets 5(20 pounds); and Terry gets 8(20 pounds), or 40 pounds, 100 pounds and 160 pounds.  Note that 40 pounds is 120 pounds less than 160 pounds, as required by the problem.

In this ratio problem, the total money is split into 15 portions. Each portion is worth 20 pounds. Russell gets 40 pounds, Sarah gets 100 pounds and Terry gets 160 pounds.

The subject of this question is ratios and its application to practical problems. In this problem, Russell, Sarah and Terry share money in the ratio 2:5:8, meaning the total money is shared in 15 portions (2+5+8). As we know that Russell gets 120 pound less than Terry, which would be 6 portions (8 portions for Terry - 2 portions for Russell).

Therefore, each portion of money is equal to 120 pound divided by 6, which is 20 pound. So, Russell receives 2 portions which equals 40 pound (2 x 20), Sarah receives 5 portions which equals 100 pound (5 x 20) and Terry receives 8 portions which equals 160 pound (8 x 20).

I hope this helps! Have a good night!

4 over 4 (4/4) is equal to 1.

The equation can be rewritten as X = 4/32

4/32 can be simplified to 1/8

So you have X = 1/8

Answer:

1/8

Step-by-step explanation:

to simplify 4/32, you just have to see how many times 4 goes into 32, in this case the answer is 8. A good rule of thumb is if the smaller number is on the top of the fraction, you will get a fraction for an answer, so the 4 turns into 1 and the 32 turns into 8.

Look at the picture.

ΔZYX and ΔDYC are similar. Therefore the lengths of sides are in proportion:

To solve the inequality 12x+7<−11 OR 5x−8>40, isolate x in each equation. The solutions are x < -1.5 and x > 9.6.

To solve for the inequality 12x+7<−11 OR 5x−8>40, we first need to simplify each equation separately i.e isolate x in each separate equation.

For the inequality 12x + 7 < -11: Subtract 7 from both sides, which gives 12x < -18. Then divide by 12 which will yield x < -1.5.

For the inequality 5x - 8 > 40: Add 8 to both sides, which gives 5x > 48. Then dividing both sides by 5, we get x > 9.6.

Our answer is therefore x < -1.5 OR x > 9.6. This means that any x value satisfying either of these conditions will satisfy the original inequality.

To solve the compound inequality 12x + 7 < -11 OR 5x - 8 > 40, solve each inequality separately to find x < -1.5 or x > 9.6. This means x can be any value less than -1.5 or greater than 9.6.

To solve for x in the given compound inequality, we need to handle each inequality separately.

Step-by-Step Solution:

Therefore, the solution to the compound inequality is x < -1.5 OR x > 9.6.

This means x can be any number less than -1.5 or greater than 9.6.

Step-by-step explanation:

First, plot all the points on a graph. Then draw Liza's path. Add them all up and multiply by 400.

28 · 400 = 11,200.

Liza walked 11,200 yards.

My graph is attached. The blue line is Liza's path and each coordinate point is labeled.

I hope this helps u!!

:)

Answer:

11,200 yards.

Step-by-step explanation:

Distance between two points is;

Distance = √(x²+y²)

Distance between Bank and post office = √(5²+0)

                                                                     = 5

Distance between post office and dry cleaner = √(0+9²)

                                                                              = 9

Distance between Dry cleaner and pizza shop = √(0+5²)

                                                                                = 5

Distance between Bank and pizza shop  = √(9²-0)

                                                                    = 9

Total distance = 5+9+5+9

                       = 28 units

1 unit ⇒ 400 yards

28 units ⇒ (28×400)

              ⇒ 11,200 Units

Answer:

315, 317, and 319

Step-by-step explanation:

So first we have to set the equation up. Since it is odd, we would write

[tex](x-2)+x+(x+2)=951[/tex]

where x is the middle integer. This gets you

[tex]3x=951[/tex]

Solving for x we get

[tex]x=317[/tex]

Since x was the middle, we subtract 2 and add 2 and put them together in ascending order, or 315, 317, and 319.

Answer:

27.27%

Step-by-step explanation:

Formula:

%= 100*(revenue-cost)/ revenue

%= 100* (121-88)/121

By 27.27%  the ticket price mark up.

The ratio of the increased value to the original value, multiplied by 100, is the percentage increase formula. It is outlined as a percentage. Anything's value will increase if it is valued more, so will its proportion.

Given:

Mark bought a concert ticket for $88.

Mark sold it for $121.

Change in amount= 121- 88 = $33.

So, the percent increase

= (121- 88) / 88 x 100

= 33/121 x 100

= 3/11 x 100

= 27.27%

Hence, the percent mark up is 27.27%.
