What is the midpoint of diagonal RB

Answers

Answer:

The midpoint is (1, 4.5)

Step-by-step explanation:

To find the midpoint, take the coordinates for the two endpoints and add the x's and divide by two. Then add the y's and divide by two. R has coordinates (-4,0) and B is (6,9). On this particular question when we just do half of the problem we can pick out the correct answer from the multiple choice list. -4 + 6 is 2. And divided by 2 is

2/2 is 1 there is only one choice that has an x that is 1. It doesn't hurt, nor take much time to confirm with the y's. 0+9 is 9. And 9/2 is 4.5.

So the midpoint is (1, 4.5)

A store owner sells soda in cases of cans and in bottles.

One case of soda contains 24 cans and costs $8.64.
Each can in the case contains 12 ounces of soda.
One bottle of soda costs $1.60 and contains 32 ounces.
What is the difference in cost between 1 ounce of soda in a bottle and 1 ounce of soda in a can?

Answers

Answer:

Step-by-step explanation:

so for the cans 24*12=288

288/8.64 = cost per ounce for canned

288/8.64=33.3333333 or 33 and 1/3 cents (1/3 of a dollar)

for the bottles we know 32 ounces cost 1.60

31/1.60 = cost per ounce for bottle

31/1.6=19.375 cents (3/8 of a dollar)

8/24 of a dollar for cans and 9/24 of a dollar for bottled

the difference is 1/24 of a dollar, aka 4.16 cents

Which equation represents a line that passes through (4,1/3) and has a slope of 3/4

Answers

Answer:

y = 3/4x - 8/3

Step-by-step explanation:

Slope m = 3/4 passes through (4,1/3)

y = mx + b

1/3 = 3/4(4) + b

b = 1/3 - 3 = 1/3 - 9/3 = -8/3

so y = 3/4x - 8/3

3x - 15 + 2x + 10 + 20 = 180 add like terms

5x + 15 = 180 subtract 15 from both sides

What is the equation in slope-intercept form for
the line that passes through the point (8,-3) and
has a y-intercept of -2?
A y=- 8x - 2
B. y = -x-2
c. y = –2x - 32
D. y = -2x - 8

Answers

Answer:

y = -1/8x - 2

Step-by-step explanation:

y-intercept of -2 means (0,-2)

Given (0,-2) and (8,-3)

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

m = (-3 - -2)/(8 - 0) = -1/8

Using (8,-3)

y = mx + b

-3 = -1/8(8) + b

-3 = -1 + b

b = -2

then y = -1/8x - 2

Angie runs 7 mph for the first half of a marathon, 13.1
miles, but twists her knee and must walk 2 mph for the
second half. What was her average speed? Round to 2
decimal places.

Answers

Answer:

Step-by-step explanation:

For the first half of the Marathon, we need to find the time.

t = d/r

r = 7 mph

d = 13.1

t = 13.1 / 7

t = 1.87 hours.

For the second half of the Marathon we need the time as well.

t = d/r

r = 2 mph

d = 13.1

t = 13.1 / 2

t = 6.55 hours.

Now to find the average speed, you will need the total time and the total distance

Total distance = 13.1 + 13.1 = 26.2 miles

Total time = t1 + t2

Total time = 1.87 hours + 6.55 hours.

Total time =  8.42

average speed = Total Distance / total time

average speed = 26.2 / 8.42 = 3.11 miles per hour

5x = y + 6
5x + 2y = 3 ​

Answers

Answer:

The solution is (1, -1)

Step-by-step explanation:

Rearrange the first equation so it is in standard form just like the second equation. To do this, subtract y from both sides.

5x = y + 6

-y     -y

rewrite the equations

5x - y = 6

5x + 2y = 3

You have two choices of which variable ( x or y) you can eliminate. Regardless of choice you have to multiply one of the equations by a number. What you really want to look for is a set of twins, meaning you have the same number and the same variable. Also one has to be negative and one has to be positive. Both equations have a 5x, so I need to make one negative by multiplying the entire equation by -1. I'll do that with the top equation. This just changes the signs of each term.

-1(5x - y = 6)

-5x + y = -6

5x + 2y = 3

Add the two equations and solve for y. The -5x and 5x will now be eliminated. Remember there is a 1 in front of the y.

3y = -3

3y/3 = -3/3

y = -1

Now solve for x. Pick either of the original equations to substitute in for y. I'm going to pick the first one.

5x = y + 6

5x = -1 + 6

5x = 5

5x/5 = 5/5

x = 1

The solution is (1, -1)
