Eliminate the parameter. x = t2 + 3, y = t2 - 2

abruzzese [7]

Answer: y = x - 5

Step-by-step explanation:

"Eliminate the parameter" means we want to eliminate the extra variable and rewrite it ias one equation that only contains x, y, and possibly a constant.

The extra variable in the equations is "t". Manipulate one of the equations to solve for t². Then substitute t² = _____ it into the other equation.

x = t² + 3 → x - 3 = t²

y = t² - 2

y = (x - 3) - 2

y = x - 5

State the common factor of the terms in the polynomial 5x^2 + 30x^2 - 10x. Then factor the polynomial

tatuchka [14]

Answer:

The common factor is 5x.

The factored polynomial is: $5x(7x - 2)$

Step-by-step explanation:

Factor of the numbers:

The common factor of the numbers 5, 30 and 10 is 5, as it is the greater common divisor of them, as found below:

5 - 30 - 10|5

1 - 6 - 2

Factor of the exponents:

Between $x^2, x^2$ and $x$ , the common factor is the x with the lowest exponent. So x

Common factor

Number multiplied by exponents, so 5x.

Factoring the polynomial:

$5x^2 + 30x^2 - 10x = 5x(\frac{5x^2}{5x} + \frac{30x^2}{5x} - \frac{10x}{5x}) = 5x(x + 6x - 2) = 5x(7x - 2)$

The factored polynomial is: $5x(7x - 2)$
