Answer:

Step-by-step explanation:

To solve this, you need to evaluate the function at f(1), which just means that you have to plug in 1 for any x you see in the equation. For example, here f(1) = 2(1) + 2 which simplifies to 4. Next find f(5). By doing the same process you will find that this is 12. The problem asks for f(1) + f(5) so by putting those values in you will get 4+12=16. Hope this helps! :)

Answer:

F(x) = 2x + 2 is the equation given.

We are going to solve this one after the other i.e solving for f(1) 1st amd then f(5) and later adding the two together.

Solving for F(1)

F(x)= 2x + 2

This means that you substitute 1 for x in the equation.

F(1) = 2(1) + 2

= 2 + 2

= 4.

For F(5)

You substitute 5 for x in the same equation.

That is,

F(5) = 2(5) + 2

= 10 + 2

= 12

now F(1) + F(5)

= 4 + 12

= 16

Toski is building a room that is 18 feet long and 14 feet wide. Construct a scale drawing of the shed. Use a scale of inch = 2 f

AURORKA [14]

Answer:

Option A is the answer

Step-by-step explanation:

Toski is building a room having length = 18 feet

Width of the room = 14 feet

Scale has been given as 1 inch = 2 feet

∵ 2 feet = 1 inch

∴ 1 feet = $\frac{1}{2}$ feet

∴ 18 feet length of the room = $\frac{18}{2}=9$ inches

Similarly 14 feet width of the room = $\frac{14}{2}=7$ inch

Now we count the small blocks in the given options.

Option A has 9 blocks or 9 inches as the length of the room and 7 blocks or 7 inches as the width of the room.

Option A is the answer.

jeni works from 8:00-3:15 three days in a row, only taking a half-hour unpaid lunch break each day. if she is paid $15 per hour,

enyata [817]

Jeni gets paid $ 303.75 for 3 days

Solution:

Given that,

Jeni works from 8:00-3:15 three days in a row

Find the number of hours between 8 : 00 to 3 : 15

8 : 00 to 3 : 15 = 7 hours 15 minutes

She is taking half-hour unpaid lunch break each day

7 hours 15 minutes - half an hour = 6 hours 45 minutes

So, she works for 6 hours 45 minutes for each three days

$6\ hours\ 45\ minutes = 6 + \frac{45}{60} = 6 + 0.75 = 6.75\ hours$

She is paid $15 per hour

Therefore, total earnings for 3 days is given as:

$Total\ Earnings = 3 \times 15 \times 6.75\\\\Total\ Earnings = 303.75$

Thus she gets paid $ 303.75 for 3 days
