Skylar is answering the following math problem: The value of an investment decreased by 10%. The original amount of the investme

Alona [7]

Answer:

The given parameters of the investment are;

The rate of decrease of the investment, r = -10%

The original amount of the investment, P = $75.00

Let 'A' represent the final answer (value of the investment) after the decrease in the investment, 'r', is applied, we have;

The algebraic equation that can be used to arrive at the final answer, 'A', is given as follows;

A = P + r·P

Therefore by substituting the given values, we have;

A = $75.00 + (-10/100) × $75.00 = $75.00 - 0.1 × $75.00 = $75.00 - $7.50

A = $75.00 - $7.50 = $67.50

The final amount or answer, A = $67.50

1. Which of the following will simplify to the<br> correct solutions of y = 2x2 + 5x - 7?

natka813 [3]

Answer:

Option B

Step-by-step explanation:

Given quadratic equation is,

y = 2x² + 5x - 7

By comparing this equation with y = ax² + bx + c

a = 2, b = 5 and c = -7

Solution of the polynomial (2x² + 5x - 7) can be determined by the quadratic formula,

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

Substitute the values of a, b and c.

$x=\frac{-5\pm \sqrt{5^2-4(2)(-7)}}{2(2)}$

$=\frac{-5\pm \sqrt{25+56} }{4}$

Therefore, Option B will be answer.
