What is the slope of the line through the points (-2, -1) and (4, 3)

1. 3/2
2. 2/5
3. 2/3
4. 5/2

Answers

First find the numerator by looking for the difference between -2 and it’s axis. That would be 2. Then we count how far it is to 4, so the top would be 6. For denominator would be the same process. The distance from -1 to 0 is 1, and from 0 there to 3 is 4. 6/4 simplifies to 3/2. If you have questions just comment, that might not have made a ton of sense and I can reiterate :)

The answer is 2/3

What two numbers have a difference of 5 and a product of 3.36?

Will mark brainliest if you show work.

Answers

Answer:

the two numbers are -0.6 and -5.6

Step-by-step explanation:

start with two equations then answer

x-y=5 and x*y=3.36

take the second equation and get only one variable at one end

which is x=3.36/y

then try to exchange x with 3.36/y in the other equation so it will be

(3.36/y)-y=5 so y=-5.6 then exchange y with -5.6 in any equation lets say the first one it will be

x-(-5.6)=5 so x=-0.5

how many solutions does this have 2x + 2 = 2(x + 1)

Answers

The statement is true for any value of x, because both sides are identical

Answer:

Infinitely Many Solutions

Step-by-step explanation:

You distribute 2 into x+1

2x+2=2x+2

Subtract 2x from both sides.

2=2

Since 2 does equal 2, there are infinitely many solutions.

What are Pythagorean triplets?

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

What is pythgorean theorem ?

Pythagorean theorem is defined as to find the unknown side of a right-angled triangle. eg, Two sides of a right-angled triangle are given as 6 cm and 9 cm, then the hypotenuse (the third side) can be calculated using the formula, h² = p2²+ b²; where 'h' is the hypotenuse and 'p' and 'b' are the perpendicular and base.

Here,
let the hypotenuse be h
now applying the Pythagorean theorem,

h² = 9² + 12²
h²= 81 + 144
h² = 225
h = √225
h = 15

Thus, the required length of the slanted area is 15 yards.
