Answer:

Correct option is:

A. $125.91

Step-by-step explanation:

Cost of each CD= $13.99

Cost of 9 CDs= $13.99×9

                      = $ 13.99(10-1)

                      = $ (13.99×10-13.99×1)   (using distributive property)

                       = $ (139.9-13.99)

                       = $125.91

Hence, Correct option is:

A. $125.91

If the discriminant, b^2-4ac is ___, a quadratic will have two real roots, two points of intersection with the x-axis.
den301095 [7]

If the discriminant, b² - 4ac is<u> positive</u>

<h3>How to complete the statement?</h3>

From the question, we have the following equation of discriminant

The discriminant (d) is calculated as

d = b² - 4ac

The solutions of a quadratic equation are dependent on the following conditions

  • If d = 0, the quadratic equation has 1 real solution
  • If d < 0, the quadratic equation has imaginary solutions
  • If d > 0, the quadratic equation has 2 different real solutions

This means that "d > 0, the quadratic equation has 2 different real solutions" implies that the discriminant is positive

Hence, the complete statement is (b) positive

Find the x-intercept of the function f(x) = a^x + 1 - 1.
babymother [125]

I am not certain of what you wrote for the function but will assume that is likely exponential function or quadratic function.

First, (quadratic function) To solve this, you must know the quadratic formula. The x-intercept is value(s) that has the output value(y) of 0.

If the vertex of the quadratic function of (0,0), there is only one x-intercept. The number and value of the x-intercept depends on the slope and vertical displacement.

Second, (exponential function) note that there is no x-intercept. For instance, if a is 2, is there such value y that 2^y is 0? The smallest exponential value that is an integer is 1. Even broadening the limit to rational numbers, no such exponential value can have the result of 0. Therefore, in the basic form of exponential function, there is no x-intercept.

HELP PLEASE PLEASE HELP<br> Solve for t.<br> -10t − -17t − 10t + -13 = 11
Marta_Voda [28]

-10t - (-17t) - 10t + (-13) = 11   (two negative signs makes a positive)

-10t + 17t - 10t - 13 = 11  Combine like terms

-3t - 13 = 11    Add 13 on both sides

-3t = 24     Divide -3 on both sides

t = -8
