Answers

When you square each side of an equation then the resulting equation is not equivalent to the original

Yes, that is true.

If x = y, x² = y².
If x = y, substitute x into where y is;

x² = y²
x² = (x)²
Thus, yes they will be.

Jordan uses a linear equation to model the data in a table. Which reasoning might Jordan have used in the decision to model the data with a linear equation?The products of corresponding x- and y-values are equal.
The ratios of consecutive y-values are equal for evenly spaced x-values.
The change in y-values is not constant, but the change is constant for evenly spaced x-values.
The change in y-values is constant for evenly spaced x-values.

The change in x values and y values are proportional to each other for the given case. The correct option is (D).

What is the slope of straight line?

The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.

The negative slope indicates the rate of decrease while the positive shows the rate of increase.

In order to form a linear equation from a table,

The slope has to be found first.

For this, the ratio of the difference in the values of x and y are taken.

Which implies that the change in x values are directly proportional to the change in the values of y.

And the proportionality constant is known as the slope.

=> (y₂ - y₁) ∝ (x₂ - x₁)

=> (y₂ - y₁)/(x₂ - x₁) = m

Hence, the change in y values are constant for change in x values.

Expanding Brackets when cubed eg(x - 5)3 Answer given is xcubed -15xsquared + 75x -125 How do I work this? I can do two brackets but having trouble with the three brackets. Thanks

Answers

Solve like this - (x-5)^3
= (x-5)(x-5)^2
= (x-5) ( x^2 -10x + 25)
= x^3 -15x^2 + 75 - 125

Hope this helped

Not really sure how to find xy :(

Answers

that's an equilateral triangle which means that all sides and angles are equal to each other. So now if you set everything equal to each other you get 2(2x+1)=6x+7y. Now it's just algebra after that, you have to distribute then left side then isolate the variable y and you get a y value. next step is pretty simple just substitute the answer that you got for y into the original equation that included y so you can get an x value. if everything is right it should tell you that the final answer is 14.
