I need help with these questions it's too hard to fit the problem and question together ​

Mathematics
1 answer:
Alona [7]3 years ago
6 0

Step-by-step explanation:

I can give you the formulas and how to do it.

The formula for finding the slope is

y²-y¹ all over(divided by) x²-x¹.

You take the order pairs and you label them.

For example, the first one.

(4,2) 4 can be x¹ and 2 can be y¹

(7,6.5) 7 can be x² and 6.5 can be y²

So then you plug it in.

(6.5-2) all over/divided by (7-4)

That ends up being 4.5 over 3. Fraction form.

That is your slope.

Then you plug the slope into the point-slope formula which is

y-y¹=M(x-x¹).

You plug your slope in for M.

You pick either of the given points and plug it in for y¹ and x¹.

Then you solve.

If done right, your formula will end up matching the slope-intercept formula

y=Mx+b.

M is your slope.

b is your y-intercept.

Dont freak out when you start doing it with fractions. Just because it looks wierd, doesnt mean it's wrong.

Use this process for all four.

Hope this helps.

The sum of two numbers is 21.
mafiozo [28]

Answer:

Pretend that x and y represents the 2 numbers that we need to find.

According to the information, we know that:

x + y = 21

6x = y

Replace y in the first equation with 6x (because they are equal to each other according to the second equation):

x + y = 21

x + 6x = 21

7x = 21

x = 21/7 = 3

Now have two ways to find y, both will give us the same result:

3 + y = 21 ⇔ y = 21 - 3 = 18

6 · 3 = y ⇔ y = 18

So the numbers that we need to find are 3 and 18.
