Marcus wants to save $378 in order to buy a new electronic
melomori [17]

Marcus would need to save for 24 weeks in order to purchase a new electronic keyboard.

<h3>Define the meaning of the equation?</h3>

A mathematical assertion in which you use mathematical symbols to demonstrate that two sums are equal.

As per specified data-

  • Marcus wishes to save $378 so that he can purchase a new electronic keyboard.
  • Every week, he saves $15.75 from his paycheck.

Let 'x' be the number of weeks required to complete the amount.

The equation becomes.

378 = 15.75x

For the number of week required.

x = 378/15.75

x = 24

Thus, Marcus would need to save for 24 weeks in order to purchase a new electronic keyboard.

Find the x and y intercept for f(x)=x^2-3x-40
Dahasolnce [82]

To find the y-intercept, simply set the value of x equal to 0, and solve for y, or f(x).

f(x) = 0^2 - 3(0) - 40

f(x) = -40

<h3>The y-intercept is -40.</h3>

Because this is a 2nd degree polynomial, we cannot find the x-intercepts in one step, and must instead use one of a few different methods.

In this case, we're going to use the quadratic formula:

\frac{-b +/- \sqrt{b^2 - 4ac} }{2a}

Plug in the values.

3 +/- √(-3^2 + 160) / 2

3 +/- √169 / 2

3 +/- 13 / 2

(3 + 13) / 2 = 16 / 2 = 8

(3 - 13) = -10 / 2 = -5

<h3>The x intercepts are 8, and -5.</h3>
