What is the point slope form of (-7,5) , (1,-1)​

Mathematics
1 answer:
qwelly [4]3 years ago

Answer:

y-5=-2/3(x-(-7))

Step-by-step explanation:

I just learned this recently as well so bare with me.

So the point slope form is y-y1=m(x-x1)

So first we have to find the slope. So we do 5-(-1)/-7-1=-6/8=-3/4

So now, we just have to plug in the numbers.

So y-5=-2/3(x-(-7)).

I know that looks a little funky but if you used the slope intercept form, you would get the same answer if you just simplified this version. Of course, you don't have to simplify this version because this version is completely acceptable.

I hope this helped.

Answer: Choice A) Factoring

Factoring is the best method since we can factor it to (x-3)(x-2) and then use the zero product property.

Answer:

The answer is 5th angle = \bold{42^\circ}

Step-by-step explanation:

Given that pizza is divided into six unequal slices.

Largest slice has an angle of 90^\circ.

He eats the pizza from largest to smallest.

Let the difference in angles in each slice = d^\circ

1st angle = 90^\circ

2nd angle = 90-d

3rd angle = 90-d-d = 90 - 2d

4th angle = 90-2d-d = 90 - 3d

5th angle = 90-3d-d = 90 - 4d

6th angle = 90-4d -d = 90 - 5d

We know that the sum of all the angles will be equal to 360^\circ (The sum of all the angles subtended at the center).

i.e.

90+90-d+90-2d+90-3d+90-4d+90-5d=360\\\Rightarrow 540 - 15d = 360\\\Rightarrow 15d = 540 -360\\\Rightarrow 15d = 180\\\Rightarrow d = 12^\circ

So, the angles will be:

1st angle = 90^\circ

2nd angle = 90- 12 = 78

3rd angle = 78-12 = 66

4th angle = 66-12 = 54

5th angle = 54-12 = 42

6th angle = 42 -12 = 30

So, the answer is 5th angle = \bold{42^\circ}
