We have two points:
(-3,5) and (2,-3)
I
An equation in oint-slope form has this shape:
y-y₀=m(x-x₀)
m=slope
1) we compute the slope (m) between two points:
Given two points (x₁,y₁) and (x₂,y₂) the slope between these pointw will be.
m=(y₂-y₁)/(x₂-x₁)
In this case, our slope would be:
m=(-3-5)/(2+3)=-8/5
2) we choose one of these points and replace it in the equation, the result will be the same:
(-3,5)
<span>y-y₀=m(x-x₀)
</span>y-5=-8/5(x+3)
Answer: y-5=-8/5(x+3)
The expression x²-14x+31=63 is a quadratic
equation. To solve it, you must order it:
x²-14x+31-63=0
x²-14x-32=0
Then, you must apply the quadratic formula, which is shown
below:
x=(-b±√(b^2-4ac))/2a
So you have the values of a,b and c:
:
a=1
b=-14
c=-32
When you substitute those values
in the quadratic formula, you obtain:
x=(-(-14)±√((-14)^2-4(1)(-32))/2(1)
x1=-2
x2=16
So, the correct option is the third one: x=-2 or x=16

Answer:
option: (a),(b),(c)
Step-by-step explanation:
- WaterSense Toilets use 1.28 gallons per flush or less while still providing equal or superior performance. This is 20 percent less water than the current federal standard of 1.6 gallons per flush.
Hence, option D is incorrect.
- it was developed with an aim of replacing an old, leaky toilet that is wasting money and water, installing a WaterSense labeled toilet is a high-performance, water-efficient option worth considering.
" The toilet float is a device that allows water to fill the tank without overflowing " .
Hence, option (a),(b) and (c) are true.
