Answer:
The slope is 3/4
Please correct me if I am wrong please and thank you
Step-by-step explanation:
I use the slope formula
Plug in (2,1) and (-2,-2)
1-(-2)/2-2
= 3/4
PLZ HELP ill GIVE BRAINIESt!!!!

This problem can be modeled by the picture shown below. We notice that we are given to side lengths, specifically legs, of the triangle. Therefore, we can use the Pythagorean Theorem, which states that a^2+b^2=c^2, where a and b are legs and c is the hypotenuse. So we can do:
16^2+12^2=c^2
256+144=c^2
400=c^2
The square root of 400 is 20, which is our hypotenuse.
(You might wonder why we used 12, that is because the whole base length is 24, but we only need half of the base to use the Pythagorean Theorem. 24/2 is 12).

Answer:
see explanation
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
=
[ 2a₁ + (n - 1)d ]
where a₁ is the initial value and d the common difference
Given
=
[ 10 + (n - 1)3 ]
Then by comparison
2a₁ = 10 ( divide both sides by 2 )
a₁ = 4 ← initial value
and d = 3 ← common difference
Thus
=
[ 10 + (7 × 3) ]
= 4(10 + 21)
= 4 × 31
= 124
X + y = -54
xy = -16
x + y = -54
2.8 + y = -54
- 2.8 - 2.8
y = -56.8
(x, y) = (2.8, -56.8)
or
x + y = -54
-56.8 + y = -54
+ 56.8 + 56.8
y = 2.8
(x, y) = (-56.8, 2.8)
The two numbers that add up to -54 and multiply to -16 are -56.8 and 2.8.
