Answer:

Y=-3x+3

-4. _ 15

-2. _ 9

0. _ 3

2. _-3

Step-by-step explanation:

When we have a function we just have to replace the X by the numbers on the table in this case -4, -2, 0 and 2

So we have

y=-3(-4)+3 ⇒12+3=15
y=-3(-2)+3⇒6+3=9
y=-3(0)+3⇒3=3
y=-3(2)+3⇒-6+3=-3

ANSWER

Eva is correct because 13/2 + 3/2 = 8

There is no mistake. Dakota may have thought that there was a mistake because Eva simplified when she got the answer for 4x which is correct but Dakota may have thought that it was incorrect.

Luke's Bakery recently spent a total of $69 on new equipment, and their average hourly operating costs are $15. Their average ho

WINSTONCH [101]

Answer:

It will take the bakery 2.875 hours to make back the amount invested.

The total expenses and receipts, both will = $112.125

Step-by-step explanation:

Given:

Cost of equipment = $69

Operation cost per hour = $15

Average hourly receipts = $39

To find how many hours will it take for the Bakery to make back the amount invested and what would the total expenses and receipts both equal

Solution:

Let the bakery take $t$ hours to make back the amount invested.

Operation cost for $t$ hours in dollars will be = $15t$

Equipment cost = $69

Total expenses in dollars can be given as = $15t+69$

Receipts for $t$ hours in dollars will be = $39t$

Since the bakery makes up the amount invested in $t$ hours, so the amount in expenses must be equal to the total receipts for $t$ hours.

Thus, we have:

$39t=15t+69$

Subtracting both sides by $15t$

$39t-15t=15t-15t+69$

$24t=69$

Dividing both sides by 24.

$\frac{24t}{24}=\frac{69}{24}$

∴ $t=2.875$

So, in 2.875 hours the bakery will be able to make back all the investment.

Total expenses in 2.875 hours will be = $15(2.875)+69=43.125+69=\$112.125$

Total receipts will be the same and can be given as = $39\times 2.875 = \$112.125$

Can you help me find this answer

IRISSAK [1]

Answer:

a= 18 girls in the class, b= 20 boys and 15 girls, 12 oranges better price.

Step-by-step explanation:

for question a, there are 18 girls in the class, this is how i worked it out:

the ratio of boys to girls is 4:3.

there are 24 boys.

24 is 6 times more than 4.

if boys are 6 times more than the original ratio, we also have to times the amount of girls by 6.

6x3= 18.

for question b i got 20 boys and 15 girls, this is how i did it.

there are 35 students in total.

4:3= boys to girls.

4+3=7

7 goes into 35 five times.

ratio of boys to girls is 4:3 so 5x4 for boys = 20 and 3x5 for girls = 15.

answer= 20 boys and 15 girls.

12 oranges is a better deal, this is how i worked it out.

it is 60 for 12 oranges.

it is 48 for 8 oranges.

12x5= 60 , 8x6=48.

you only have to times 12 by 5 to get it to the price but you have to times 8 by 6 to get it to the price, proving that 12 oranges for 60 is a better deal.

A car sells for 16000 if the rate of depreciation is %18 find the value of the car after 8 years

marusya05 [52]

Answer:

Hence the sell value of car after 8 years at 8% depreciation = 3270.62 unit

Step-by-step explanation:

Given as ,

A car initial sells value = 16000 unit

Depreciation rate of sell = 18 %

Time for depreciation = 8 years

Now , The value of car after 8 years = $initial sell value \times (1 - \frac{Rate}{100})^T$

Or, = $16000 \times (1 - \frac{18}{100})^8$

= 16000 × 0.2144

= 3270.62 unit

Hence the sell value of car after 8 years at 8% depreciation = 3270.62 unit Answer
