The expression 1.22y is the amount spent by Jonathan.

<u>Step-by-step explanation</u>:

  • The cost per pencil = $0.28

∴ The total cost of 3 pencils = 0.28\times3 = $0.84

  • The cost per eraser = $0.38

∴ The total cost of y erasers = 0.38\timesy = $0.38y

Jonathan spent = Total cost of pencil + total cost of eraser

⇒ 0.84 + 0.38y

⇒ 1.22y

Solve for j. 144j2 + 21 = 85
Sphinxa [80]

Answer:

2/3

Step-by-step explanation:

I assume the 2 after the j is a square. So, we bring the 21 to the other side by subtracting it from both sides, getting 144j^2=64. Now we divide to get 64/144 = j^2. Make sure NOT to simplify it, it's perfect right now. The square root of that is \sqrt{64}/ \sqrt{144}, or 8/12, which we can now simplify to 2/3. Hope this helps!

On the graph shown, what is f(-1)? (5 points) The first segment joints the point negative three comma five exclusively and negat
tatiyna
ANSWER

f( - 1) = 2

EXPLANATION

The given function is a piecewise defined function.

f( - 1)
is the y-value that corresponds to
x = - 1.

To determine that y-value, we need to trace from
x = - 1
to where it meets the graph.

We then trace to the y-axis to determine the corresponding y-value as shown in the diagram.

From the graph, we can see that this x-value corresponds to a y-value of
2

This implies that, when
x = - 1,y = 2

Therefore
f( - 1) = 2
See graph.
