Answer:

The first question is -1.25

I don't know the answer to the second one, but i think it's +2.5

Step-by-step explanation:

y is the same as fx

the rate of change is also the slope, and as x increases by 4, y decreases by 5, slope is change in y / change in x, so -5/4 = -1.25, every hour the candle's length decreases by 1.25.

4 hours is $50, 40 hours is $500, 160 hours is $2000, 200 hours is $2500.

i’m pretty sure this is right because she makes $12.5 an hour.

Answer:

$ 500 ~40 horus

$ 2000 ~160hours

$ 2500 ~200hours

Step-by-step explanation:

Assume that the rate of earnings is constant, then one can manipulate the first ratio to get to the succeeding ratios. A ratio is a way of expressing one value compared to another when the two values have different units. In this case, the ratio is: (hours : earnings)

hours : earnings

4 : 50

First, one is asked to find how much is earned in (40) hours, since the rate is constant, all one has to do is multiply the hours by (10) to get to (40),

40 : 500

Next, one is asked to find how much is earned in (160) hours, now multiply the previous rate by (4), to get to 160,

160: 2000

Finally, one is asked to find out how much is earned in (200) hours, multiply the rate which gives one how much is earned in (40) hours by (5),

200 : 2500

The system of equations represented by lines p and q is shown on the graph below. Based on the graph, what is the solution of the system of equations?

Answers

Answer:

Step-by-step explanation:

the x is 2 and y is 1 which makes it (2,1)

The solution to the system of linear equations given in the graph is: C. (2, 1)

Recall:

The solution of a system of equations that are represented on a graph is the point of intersection of the two lines of each linear graph. The solution is the coordinate of the point where both lines intersect on the graph.

Thus, from the graph given, the coordinate of the point of intersection is, (2, 1).

Therefore, the solution to the system of linear equations given in the graph is: C. (2, 1)

Alexa is saving to buy a new bike that costs $265. So far she has saved $45. If she is able to save $11 each week, how many weeks will it take her to save enough to buy her coveted bike?
Kole wrote (265 - 45)/11 = w.
Bella wrote 11w + 45 = 265.
Who do you agree with? Justify your response.

Answers

Answer:

nose

Step-by-step explanation:

They are both correct to an extent; however, Kole is more correct in the fact that he simplified the equation. Where Bella has the right idea but did not simplify the equation.

I agree with Kole because 220/11 =20 weeks until she has saved enough for her bike.

Both equations get you the correct answer though:

Kole: 265-45=220/11=20 weeks

Bella: 11w + 45 = 265 ... subtract 45 from both sides ... 11w = 220 ... divide both sides by 11 and you get 20 weeks

Answer:

7 degrees (above zero)

Step-by-step explanation:

-5 + 12 = 7

or on a number line plat at -5 and count 12 to the right and you end on +7

Well... You didn't specify whether or not it is Farenheight or Celsius, So im going to show both.

Farenheight:

-5 + 12 = 7

Because

... A simple breaking way to show it would be: 12-5=7 -5+5=0 0+7 = 7

Celsius:

Its the same :)

If you were going to convert it to Farenheight though:

-5 Celsius = 23* Farenheight.

12 Celsius = 53.6* Farenheight

+56.3
