Find the slope of the line that goes through the points (-8,6) and (7,-3).
-3/5
-5/3
-1/3
1/3
Answer:
-3/5
Step-by-step explanation:
[tex]slope = \frac{ - 3 - 6}{7 - ( - 8)} \\ \\ = \frac{ - 9}{7 + 8} \\ \\ = \frac{ - 9}{15} \\ \\ = - \frac{3}{5} \\ [/tex]
The slope of the line that goes through the points (–8, 6) and (7, –3) is –3 / 5
Slope of a lineSlope = Chang in y-coordinate / change in x-coordinate

An airplane travels 500 miles an hour.
How long will it take to travel 4.000 miles?
An airplane travels 500 miles an hour then it will take 8 hours to travel 4.000 miles.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
An airplane travels 500 miles an hour. We need to find how long it will take to travel 4.000 miles.
We know that
Let t be the time taken by an airplane to travel 4000 miles.
An airplane traveled 500 miles = 1 hour
An airplane traveled in 1 mile = 1/ 500
An airplane traveled in 4000 miles = 4000/500
= 8 hour
Thus, It will take the airplane 8 hours to travel 4,000 miles.

Step-by-step explanation:
 Please create a graph to reflect the following situation:
Max is going to school. For the first 20 minutes he walks at a constant speed of 10 miles per hour. Then he gets to the bus stop and waits for the bus for another 5 minutes. Then he rides the bus for 10 minutes. The speed of the bus is 40 miles per hour.
Show graphically the distance Max has traveled to school over time since he has left his house.
Make sure you include the name of the graph, the labels and the scale on x- and y-axes; Please use graphing paper, pencil and a ruler. Please help me it’s due today I would love the help.
You show the time on the x-axes (from 0 to 35) and the distance on the y-axes (from 0 to 10).
You start at origin of coordinates. Then the graph rises linear until it reaches the point (20|3.3333...), then it is parallel to the x-axes (as he does not move) until it reaches (25|3.3333...). Then it increases again until it reaches (35|10).
Basically, it's linear all the time, while the slope of the graph varies in three different intervals. (Actually it wouldn't be linear as he doesn't move with the same speed all the time but we can't go more into detail based on the information we have, so we use average values.)
You can use the rule of three to find out how far he moves.

Veronica bought 20 bags of candy for a school dance. The first 5 bags cost $1.79 each. The rest of the bags cost $1.19 each.
How much did Veronica spend on candy?
A. 8.95
B. 17.90
C. 26.80
D. 35.80
Answer:
Your answer is C. 26.8
Step-by-step explanation:
5 × 1.79 = 8.95
15 × 1.19 = 17.85
8.95 + 17.85 = 26.8
Answer: C ($26.80)
Step-by-step explanation:
This is a multiplication problem.
The first 5 bags of candy cost $1.79 each, so we multiply the cost by the amount of bags that we bought for that price:
5 * 1.79 = $8.95
The rest of the bags cost $1.19 each, so we need to multiply this number by some value. To find this value, we need to know how many bags we have left. We already bought 5, and we bought a total of 20, so we need to buy:
20 - 5 = 15 bags
Multiplying the cost for the rest of the bags (1.19) by the amount of bags we need to buy still (15), we get:
15 * 1.19 = $17.85
Now we know what the cost of the first 5 bags (8.95), and we know the cost of the 15 other bags (17.85). To find the total amount of money Veronica spent, we can just add these two values together.
8.95 + 17.85 = $26.80
This total cost is shown in answer C, so that is the answer.

Step-by-step explanation:
Kim saved $250 to buy new clothes for her summer vacation. She found several items she would like to buy, but is trying to decide if she has enough money to buy all the items she likes. She found a bathing suit for $35, two pairs of shoes for $15 each and five shirts with an average cost of $17 per shirt. She will have to pay 6% sales tax. If she buys all of the items, how much sales tax will she have to pay?
Answer:
She will have to pay $9 as sales tax
Step-by-step explanation:
Total amount with Kim = $250
Bathing suit = $35
Two pairs of shoes = 2 × $15
= $30
Five shirts = 5 × $17
= $85
Cost of items = Bathing suit + Two pairs of shoes + Five shirts
= $35 + $30 + $85
= $150
Sales tax = 6%
Amount of sales tax paid = 6% of $150
= 6/100 × 150
= 0.06 × 150
= $9
Kim will have to pay $9 as sales tax
Total cost of the items = cost of items + sales tax
= $150 + $9
= $159
Kim has enough money to buy all the items she likes
