B)

~ Substitute x = 2 into the equation and if the result is equal to the y- coordinate of the point then it is a solution.

~ y = 3(2) - 2 = 6 - 2 = 4 ≠ - 1

(2, - 1) is not a solution to the equation.

D)

~ The point (2, - 1) only lies on the line sloping downwards from left to right.

~ So it’s is a solution to that equation.

Answer:

see explanation

Step-by-step explanation:

B

To determine if (2, - 1) is a solution to y = 3x - 2

Substitute x = 2 into the equation and if the result is equal to the y- coordinate of the point then it is a solution.

y = 3(2) - 2 = 6 - 2 = 4 ≠ - 1

Thus (2, - 1) is not a solution to the equation.

D

The point (2, - 1) only lies on the line sloping downwards from left to right.

It is therefore a solution to that equation but not the other.

How can you quickly determine the number of roots a polynomial will have by looking at the equation?
Goryan [66]
First, you need to get delta which is b squared minus 4ac. If delta is higher than cero, the polynomial has two solutions, if it is less, the polynomial has no real solutions and if it is the same, it has one solution.
Although that is only for second grade ecuations

HELP URGENT!!!!!!!!!!!!!!!!!!!!!!!!
r-ruslan [8.4K]

Answer:

The equation has an Inifinite amount of solutions

Step-by-step explanation:

2 ( 3g + 2 ) = 1/2 ( 12g + 8 )

First use the distributive property of multiplication -

6g + 4 = 6g + 4

6g cancels out from both sides of the equation -

4 = 4

When both sides of an equation are the same there is an infinite amount of solutions.

Hope this helped! :)

The area of rectangle ABCD can be expressed in simplified form as: 8y^2 - 10y.

<h3>How to Calculate the Area of a Rectangle?</h3>

The area of a rectangle is calculated using:

Area = (length)(height).

We are given the following:

Length of rectangle ABCD = side DC = 4y - 5

Height of rectangle ABCD = side AD = 2y

The area of rectangle ABCD = (length)(height) = (4y - 5)(2y).

Expand the expression

The area of rectangle ABCD = 2y(4y) - 2y(5) [distributive property of multiplication]

The area of rectangle ABCD = 8y^2 - 10y

Thus, the area of rectangle ABCD can be expressed in simplified form as: 8y^2 - 10y.
