Find the slope between the two points: (3,-2) and (4,7)

1 answer:

5 0

To find slope given two points, there is a formula you can use: (y2-y1)/(x2-x1). Y2 stands for the second y coordinate and y1 stands for the first y coordinate. The same logic applies to the x's. Let's assume that (3, -2) is x1, y1 and (4,7) is x2, y2. Let's plug them into the formula.

(7-(-2))/(4-3).
7-(-2)=9 for total y value.

4-3=1 for the x value.

Now we divide them.
9/1=9. 9=m. M is the variable commonly used for slope. Hope this helped!

Brad buys a pack of 12 bottles of energy drink for £9.25 he then sells all bottles for £1 each. Work out brads percentage profit

docker41 [41]

Brad's profit was 30%

Further explanation:

Profit is the money someone earns on selling a product on more than its actual cost.

The formula for profit is:

$Profit= Selling\ price-Purchase\ price$

Given

Purchase price of energy drinks = £9.25

Selling price of one bottle=£1

Selling price of 12 bottles=1*12=£12

Profit= Selling Price - Purchse price

=12-9.25

=£2.75

Brad's profit was £2.75

Now,

Profit percentage= (Profit/Purchase Price)*100

=(2.75/9.25)*100

=0.30*100

=30%

Brad's profit was 30%

Shkiper50 [21]

Answer:

step 3: place the tip of the compass at point x and strike the arc at point y

Step-by-step explanation:

congruent triangles are triangles that have equal shape and size. They are the same in every way. this is the reason why they are called CONGRUENT

we have been asked to construct an angle MNT congruent to angle PQR. this means we are to construct angle that is the same as that at PQR.

with a ruler and a compass we can easily make a replica of the angle at PQR.

following the steps given in the question including step 3 that i have just added, the angle MNT will be the same as the angle PQR
