Answer:

C. y = -5x + 4

Step-by-step explanation:

segment with endpoints (–5, 3) and (5, 5)

Slope m = (y2-y1)/(x2-x1)

m = (5 - 3)/(5 - -5) = 2/10 = 1/5

Perpendicular lines have slopes that are negative reciprocals of one another. So slope of bisector is -5

Bisector intersects the segment at midpoints so

x = (Xa + Xb)/2 = (-5 + 5)/2 = 0/2 = 0

y = (Ya + Yb)/2 = (3 + 5)/2 = 8/2 = 4

so midpoint is (0,4)

using slope = -5

y = mx + b

4 = -5(0) + b

b = 4

then y = -5x + 4

Answer:

b = -4

Step-by-step explanation:

-(1/2)(b-6) = 5

(-1(b-6))/2 = 5

(-b+6)/2 = 5

-b+6 = 5(2)

-b+6 = 10

b-6 = -10

b = -10+6

b = -4

Answer:

-14x + 21

Step-by-step explanation:

Use the distributive property to solve. Multiply -7 by each number in parentheses. -7 times 2x is -14 x and -7 time -3 is 21 (a negative times a negative is a positive). You should get -14x + 21 as an answer. You are no longer able to simplify any farther from there.

or, z + 106° = 180° ( being straight angle )

or, z = 180°- 106°

•°• z = 74°

Now,

or, z + y = 180° ( being co-interior angle )

or, 74° + y = 180°

or, y = 180° - 74°

•°• y = 106°

~nightmare 5474~

The value of x is 74.

The value of y is 106.

The sum of angles on a straight line is 180. In order to determine the value of x, subtract 106 from 180.

x = 180 - 106 = 74

In order to determine the value of y, subtract 180 from 74

180 - 74 = 106.

Step-by-step explanation:

we have to simplify it as much a possible.

that means we divide top and bottom by the same whole number, until we cannot find any other number except for 1, where there is no remainder for these divisions.

so, usually if we don't see the solution right away, we go along the prime numbers starting with 2 :

can we divide 48 and 54 by 2 without remainder ?

yes, and the result is then

24/27

can we divide 24 and 27 by 2 without remainder ?

no. going to the next prime number : 3

can we divide 24 and 27 by 3 without remainder ?

yes, and the result is

8/9

can we divide 8 and 9 by 3 without remainder ?

no. and there is no other prime number I can divide both numbers with.

so, 8/9 is the lowest or simplest form.

Answer: Choice A

Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin

====================================================

Explanation:

The point A(4,3) means we start at the origin and move 4 units to the right and 3 units up. The x and y axis are separate number lines to mark a location

B(2,1) means we move 2 units to the right and 1 unit up

C(3,4) means we move 3 units to the right and 4 units up

Each time we plot a new point, we always start at the origin.

Answer:(4, 3)

Step-by-step explanation: A. A coordinate plane has an x-axis from 0 to 7 in increments of 1 and a y-axis from 0 to 7 in increments of 1. Point A is plotted 4 units to the right and 3 units above the origin. Point B is plotted 2 units to the right of and 1 unit above the origin. Point C is plotted 3 units to the right and 4 units above the origin.

The number of boxes that the truck can hold if it is already 65% full is; 49 boxes

We are given the truck dimensions as;

Formula for volume of truck is;

V = L × w × h

Thus;

V_truck = 10 × 10 × 14

V_truck = 1400 ft³

Volume of boxes is;

V_box = 2 × 2 × 2.5

V_box = 10 ft³

We are told that truck is 65% full.

Thus;

Volume left in truck = 35% × 1400

Volume left in truck = 490 ft³

Thus;

Number of boxes the truck can hold at the 65% capacity = 490/10 = 49 boxes

One quarter is equal to the 0.25 dollars and one nickel equal to the 0.05 dollars. The total number of quarter in the Sang-Jin's piggy bank is 41.

Given information-

Sang-Jin has only quarters and nickels in her piggy bank.

She has 66 coins in the bank with a value of $11.50.

One quarter is equal to the 0.25 dollars.

One nickel equal to the 0.05 dollars.

Let x be the quarter and y be the nickels.

As there is total 66 coins. thus,

[tex]x+y=66\\ y=66-x[/tex]

Suppose the above equation as the equation number 1.

As the total amount is $11.50. Thus,

[tex]0.25x+0.05y=11.50[/tex]

Put the value of y from the equations 1 in the above equation. Thus,

[tex]0.25x+0.05(66-x)=11.50\\ 0.25x+3.3-0.05x=11.50\\ 0.2x=11.5-3.3\\ x=\dfrac{8.2}{0.2}\\ x=41[/tex]

Thus the total number of quarter in the Sang-Jin's piggy bank is 41.

The inequality that describes the problem is x - 30 ≤ 15

Let x represent how much money Michael expects to spend on sports wear

If Michael just started middle school this year, and his grandmother will give him some money to buy new spirit wear and buys hoodie for $30, the balance remaining will be x - 30

If Michael figures he'll need at most $15 more to buy a T-shirt, hence the resulting inequality will be:

x - 30 ≤ 15

Add 30 to both sides

x - 30 + 30  ≤ 15 + 30

x  ≤ 45

Hence the inequality that describes the problem is x - 30 ≤ 15 and Michael expects to spend at most $45 on sports wear.

Answer:

a. $160

b. $894

Step-by-step explanation:

according the the info we have, each square is 1/4 of an inch. so 4 squares would equal one inch (1/4 x 4 = 1). and one inch is a scale of 16 feet. to find the length of one square:

1 inch = 4 squares

4 squares = 16 feet

1 square = 1/4 of an inch

1/4 of an inch = 1/4 of 4 squares

1 square = 1/4 of 16 feet    {1 square = 1/4 of an inch and 4 squares = 16 feet}

1 square = 4 square feet

a. count the number of squares: 8

now find the number of square feet 8 squares are using the conversion:

8 x 4 = 32

the bathroom is 32 square feet

one square foot of tile costs $5

now find the cost of 32 square feet:

$5 x 32 = $160

b. the square feet of the bathroom in 32 sqft

now do the same thing before for the living room:

28 square, so the living room is 112 (because 1 square = 4 square feet)

the find the cost of carpet per square foot, divide the cost per yard by 3 (1 yard = 3 feet)

18/3 = 6

so one square foot of carpet costs $6

now find the cost to carpet the bathroom and living room:

$6 x 32 = $192

$6 x 112 = $672

the total cost is

$672 + $192 = $894

the total cost to carpet the bathroom and living room is $894

p.s. who carpets their bathroom? lol
