The cost of a service call to fix a washing machine can be expressed by the linear function y = 45 x + 35, where y represents th

e total cost and x represents the number of hours it takes to fix the machine. What does the y-intercept represent? the cost for each hour it takes to repair the machine the service fee for coming to look at the machine the total cost for fixing the washing machine the amount of time that it takes to arrive at the home to make the repairs

The y-intercept is where the line starts on a graph. The y-intercept is 35.

This number doesn't change ever in the linear expression.

"45x" represents the slope of the line and "the number of hours it takes to fix the machine." y represents the total cost.

35 is the only value that doesn't get altered in the expression because its by it self.

The first option doesn't make much sense because it represents "45x" not the y-intercept.

The second option makes sense because the cost for looking at the machine doesn't change which represents the starting amount.

The third option doesn't make much sense because the total cost to fix the machine is represented by "y" in the original expression. It even says so in the question, "where y represents the total cost."

The fourth option doesn't make much sense because it has nothing to do with the actual problem it self.

Therefore, the only logical answer is "the service fee for coming to look at the machine."

Best of Luck!

Answer:

B. The service fee for coming to look at the machine

Step-by-step explanation:

Whenever we have a linear equation like this in real-world problems, the y-intercept always represents a fixed cost of some sort.

Here, 35 is the y-intercept. It cannot represent "the cost for each hour it takes to repair the machine" because that's what 45 means.

It cannot represent "the total cost for fixing the washing machine" because that's what y means.

And it cannot represent "the amount of time that it takes to arrive at the home to make the repairs" because that's what x means.

Thus, 35 must be the service fee. This is the upfront fee that is fixed and doesn't change depending on time.

Hope this helps!

If I bought shoes for 32.30 with 15% off 7%sales tax a 25dollar gift card but had a coupon that was forgotten for 5%off the orig
Otrada [13]

Answer:

 $4.37 cash outlay

 $29.37 total amount paid, partly with gift card

Step-by-step explanation:

The discount was ...

  0.15 × $32.30 = $4.845 ≈ $4.85

So the price to which tax is added is ...

  $32.30 -4.85 = $27.45

The amount of tax is 7% of this value, or ...

  tax = $27.45 × 0.07 = $1.9215 ≈ $1.92

So, payment is made on the amount ...

  $27.45 + 1.92 = $29.37

$29.37 is the total amount paid.

If $25 is paid using a gift card, then the cash outlay is $4.37.

_____

Usually only a single coupon can be applied to a given purchase. Since the 15% store discount exceeds the amount of the 5% coupon left at home, it makes more sense to claim the 15% store discount and save the 5% coupon for another time.

__

<em>Alternate interpretation</em>

If, by some magic, both discounts could be applied, then the amount to be paid is $27.65, of which $2.65 exceeds the gift card amount. The calculation proceeds the same way, except that 20% is used instead of 15%.

pav-90 [236]

Answer:

When there is no width, the area is 0m²

Step-by-step explanation:

Expressing the area of a rectangle as a function of its width:

Area of a rectangle = Length * width

Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0

When x :

Area = Length * width

Area = Length * 0

Area = 0

Area = Length * 0

Aea = 0
