Jocab will take 4 more weeks to buy that MP3 player.

<u>Step-by-step explanation:</u>

Given:

Cost of MP3 player = $ 195

Earning per week = $ 225

Expenses per week = $ 180

To Find:

Weeks still required to save money for buying MP3 player.

Formula to be used:

Savings per week = Earning - Expenses

Solution:

Savings per week = Earning - Expenses

                              = $ 225 - $ 180     = $ 45

Already saved = $ 55

Need to save = $ 195 - $ 55 = $ 140

So for 4 weeks savings = $ 45 × 4 = $ 180

Thus Jocab will take 4 more weeks to buy that MP3 player.

what is the y-intercept of the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3)?​
Deffense [45]

Answer:

1

Step-by-step explanation:

For this question, your friend is the point-slope form.

Point-slope form = y-y_1 = m(x-x_1)

The only variables you replace are m = slope, y1 = y of a given point, and x1 = x of a given point.

First, we need to find the slope that is perpendicular to the equation y=-\frac{3}{4}x+5

An equation that is perpendicular to another equation have to be negative reciprocals (negative inverse) of each other.

If the slope is 3, then the negative reciprocal of 3 is -\frac{1}{3}.

So, since the given slope is -3/4, the negative reciprocal is \frac{4}{3}.

We will use the negative reciprocal as m since we are trying to find the equation of line that includes (-3, -3) and is perpendicular to the other equation.

We will use point slope form using the (-3, -3) points and negative reciprocal as m.

y-y_1 = m(x-x_1)\\y-(-3) = \frac{4}{3} (x-(-3))\\y+3=\frac{4}{3}(x+3)

Now, we need to convert this into slope-intercept form. The reason why we need to do this is because y = mx + b, where b is the y-intercept. To do this, solve for y - or in other words, isolate y..

y+3=\frac{4}{3}(x+3)\\y+3=\frac{4x}{3}+4\\y+3-3=\frac{4x}{3}+4-3\\y=\frac{4}{3}x+1

The y-intercept of the line is 1.

What is the polynomial -9+1/8x-7x^4+x^2-x^5 in standard form
Oduvanchick [21]

Answer:

-x^5 - 7x^4 + x^2 + (1/8)x - 9

Step-by-step explanation:

Rewrite the given -9+1/8x-7x^4+x^2-x^5 in descending order of the variable x:

-9+1/8x

-x^5 - 7x^4 + x^2 + (1/8)x - 9

HELP PLEASE! Chords NO and PQ are congruent. Arc NO measures 4x + 10 and Arc PQ measures 2x + 20. What is each of their measures
Elodia [21]
4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
