Answers

Answer:

Yes

Step-by-step explanation:

An integer, also called a "round number" or “whole number,” is any positive or negative number that does not include decimal parts or fractions. For example, 3, -10, and 1,025 are all integers, but 2.76 (decimal), 1.5 (decimal), and 3 ½ (fraction) are not an integer.

Write the equation of a line that is parallel to the graph of y = − 7x − 9, and passing through the point (1, 10). SHOW ALL WORK!

Answers

Answer:

y = - 7x + 17

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 7x - 9 ← is in slope- intercept form

with slope m = - 7

Parallel lines have equal slopes, thus

y = - 7x + c ← is the partial equation

To find c substitute (1, 10) into the partial equation

10 = - 7 + c ⇒ c = 10 + 7 = 17

y = - 7x + 17 ← equation of parallel line

Answer:

y = -4/5x +3/5

Step-by-step explanation:

The 2-point form of the equation for a line can be useful.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (3 -(-1))/(-3 -2)(x -2) -1

y = 4/(-5)(x -2) -1

y = -4/5x +8/5 -1

y = -4/5x +3/5

Answers

Answer: m=3/4

Step-by-step explanation:

Looking at the table given, we can assume two of the points are (9,-24) and (13,-21). To find the slope with given points, we use the formula [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. We can plug the two points in and solve.

[tex]m=\frac{-21-(-24)}{13-9} =\frac{3}{4}[/tex]

Now, we know that the slope is 3/4.

I hope I helped but I honestly have no idea if I did. Anyway sorry if I didn't. Good luck.

The equation for supplier A and supplier B will be y = 2.59x + 85 and y = 4.29x + 50, respectively. Supplier A has the lowest average cost per ball.

What is a linear equation?

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

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

Footballs are sold at varying prices by two rival sports equipment vendors. Supplier A costs $85 for shipping and $2.59 for each football. Supplier B costs $50 for shipping and $4.29 per football. A school wants to purchase 40 balls.

Let x be the number of the football and y be the total cost.

The equation for supplier A will be given as,

y = 2.59x + 85

At x = 40, the value of 'y' is given as,

y = 2.59 × 40 + 85

y = $188.6

The equation for supplier B will be given as,

y = 4.29x + 50

At x = 40, the value of 'y' is given as,

y = 4.29 × 40 + 50

y = $221.6

Supplier A has the lowest average cost per ball.

PLSS HELP with 1 3 and 4

Answers

Answer:

1.) slope is 6

2.) slope is -4

4.)slope is undefined

Step-by-step explanation:

1.) For one we can use the equation y2-y1/ x2-x1

First, pick any 2 points that you want to use to plug into the equation

(0, -3) and (1, 3)

Next, plug in and solve!

3-(-3)/ 1-0= 6

The slope is 6

2.) We can use this same equation for the problem and plug in!

(-1, 5) (2,-7)

-7- 5/ 2-(-1)= -4

The slope is -4!

4.) Use the same equation and find the slope!

Joshua rented a movie for $4.49 from Cinema Rentals. If the movie is not returned on the due date, Cinema Rentals charges an
additional $2.25 a day until the movie is returned. If Joshua returns the movie x days after its due date, which of the following
functions represents the total cost, R(x), he paid for the movie rental?

Answers

Answer:

R(x) = 2.25x + 4.49

Step-by-step explanation:

Equation form: R(x) = mx + b

m: represents the additional amount Joshua is charged for every day until he returns the movie, which in this case is $2.25. So, the value of m is 2.25.

b: represents the initial cost of renting the movie. Joshua rented the movie for $4.49, so b is 4.49.

Since we know the value of m and b, we can write the equation:

R(x) = 2.25x + 4.49

Okay for every triangle, the degrees have to add up to 180 degrees. For example, the triangle that has c,h and 92 degrees, have to add up to 180, which means you can subtract 92 from and 180 and you’ll get 88, and since you need to find out both C and H you can divide 88 by 2 and you’ll get 44, which therefore C and H equal 44!

The ratio of the perimeter of a square to the length of a rectangle is 5:6.
The ratio of the length to the width of the rectangle is 3:2.
The perimeter of a rectangle is 60cm.
Find the area of the square.

Answers

Answer:

=225/16cm^2

Step-by-step explanation:

Given

The ratio of the length to the width of the rectangle =3:2.

The perimeter of a rectangle = 60cm.

Solution

Let length=3x

width=2x

Perimeter of rectangle=2(length + width)

2(3x+2x)=60

5x*2=60

10X=60

X=60/10

X=6

SO LENGTH =3×6=18cm

WIDTH=2×6

=12cm

Let perimeter of the square=5x

Length of rectangle=6x

6x = 18

X=18/6

X=3

SO PERIMETER OF SQUARE=5×3

4SIDE=15

Side=15/4

Area of square=15/4×15/4

=225/16cm^2
