N =D+7

0.10D +0.05(D+7) = 1.55

0.15D +0.35 = 1.55

0.15D=1.20

D=120/0.15 = 8

8x0.10 = 0.80

1.55-0.80= 0.75

8+7=15 * 0.05 = 0.75

8 dimes and 15 nickels

What is the equation of the line that passes through (4, -1) and (-2, 3)? user: if y is 5 when x is 2.5 and y varies directly wi
algol13
First find the slope of the line that passes through (4,-1) and (-2,3) by calculating "change in y" / "change in x"

So slope = -4/6 = -2/3

Remember the format y = mx + b?

So pick any of the two coordinates (I'll use (4,-1)) and sub in what you can.
-1 = -2/3(4) + b
Solve for b and you'll get 1.66666.... aka 1 2/3

So the equation is y = -2/3x + 5/3

Now for the next question.
So 5/2.5 = y/10
cross multiply and simplify and you'll get y = 20

The question is: "Without actually graphing, describe how the graph of y = ( -2^(x+17) ) - 4.3 is related to the graph of y = 2^
Leokris [45]

Answer:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.

Step-by-step explanation:

When functions are transformed there are a few simple rules:


  • Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
  • Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
  • Multiplying the function by a number less than 1 compresses it towards the x-axis.
  • Multiplying the function by a number greater than 1 stretches it away from the x-axis.
  • Multiplying by a negative flips the graph.

The graph of (-2^{x+17}) -4.3 compares to 2^x in the following ways:

The function has been flipped due to the negative in front.

The function has been shifted 17 units to the left.

The function has been shifted 4.3 units down.
