<u>Answer:</u>
- For 15 pens, the cost is $7.2
<u>Step-by-step explanation:</u>
<u>We know that:</u>
<u>Work:</u>
Divide the RHS:
- => 1 pen = 3.84/8
- => 1 pen = 0.48
Multiply the RHS:
- => 15 pens = 0.48 x 1
- => 15 pens = $7.2
Hence, <u>for 15 pens, the cost is $7.2</u>
Hoped this helped.
Answer:
Step-by-step explanation:
=125-12.5x
The slope is -12.5
The y intercept is (0,125)
Points are (0,125) and (10,0)
The horizontally compress the exponential function f(x)=2^x by a factor of 3 is f(3x)=2^3x
When we compress a function y=f(x) by a scale factor of 'k', where k >1, then the function after compression will become :
y=f(x), where k>1
We have given the Exponential function.
<h3>What is the scale factor?</h3>
The scale factor is a measure for similar figures, that look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii. The scale factor states the scale by which a figure is bigger or smaller than the original figure.
The scale factor of the compression (k): 5
Then after horizontal compression, the exponential function will become
f(3x)=2^3x

They are telling you to call Sueellen’s number of years y
y + 4 = x where x is Tara’s number of years.
Because no matter what number you plug in for why, Tara has been taking lessons for four more years than that.

Answer:
x = 15.4
Step-by-step explanation:
Because this is a right triangle, you can use the pythagorean theorem to find the length of the hypotenuse. the theorem is a^2 + b^2 = c^2
so
9^2 + 12.5^2 = c^2
solving this will give you 15.4
