Travka [436]3 years ago
3 0

Answer:

in the step-by-step

Step-by-step explanation:

okay one thing is that you labelled wrong since you have to label D', D", D'" (you just labelled with one for all of them)

a you reflected across the y-axis wrong

-it would be that D' (-2,6), E' (-2,3), F' (-5,3)

b you rotated correctly

this gets more confusing since you labelled the triangles wrong, but I hope this first part helps

Julio bought 4 pencils and 3 erasers for $0.37 and David paid $0.33 for 3 pencils and 4 erasers. What is the cost of one pencil?
grigory [225]

cost of pencil = x = 0.07

and cost of eraser = y = 0.03

Step-by-step explanation:

let cost of pencil = x

and cost of eraser = y

So, we have equations:

4x+3y=0.37\\3x+4y=0.33

Solving both equations to find value of x and y

Let:

4x+3y=0.37\,\,\,eq(1)\\3x+4y=0.33\,\,\,eq(2)

Multiply eq(1) with 4 and eq(2) with 3 and subtract

16x+12y=1.48\\9x+12y=0.99\\-\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\--------\\7x=0.49\\x=0.07

Putting value of x in equation 1:

4x+3y=0.37\\4(0.07)+3y=0.37\\0.28+3y=0.37\\3y=0.37-0.28\\3y=0.09\\y=0.03

So, x= 0.07 and  y = 0.03

cost of pencil = x = 0.07

and cost of eraser = y = 0.03

Identify the type of function represented by f(x) = 4•3^x
SVEN [57.7K]

Since the variable x is at the exponent, this is an exponential function.

To decide whether an exponential function is a growing or decaying one, we have to look at the base of the exponent.

If the base is between 0 and 1, we have exponential decay

If the base is larger than 1, we have exponential growth.

In your case the base is 3, which is larger than 1, so you have exponential growth.

Thus, <u>option d</u> is your answer
