Which number is prime?<br> 63 <br> 51 <br> 61 <br> 57
kondor19780726 [428]
Hey there!

No numbers go into a prime number other than one and that number. 9 and 7 go into 63, so it’s not 63. 3 and 17 go into 51, so it’s not 51. 19 and 3 go into 57, so it’s not 57. That leaves 61. Nothing goes into this other than one and 61, so the answer is 61.

I hope this helps!

1. Find f(6)<br> 2. For what values of x is f(x) = 0?
Varvara68 [4.7K]

Answer:

f(6) = -5

f(x) = 0 and x=1 and x=5

Step-by-step explanation:

f(6) is the value when x=6

looking at the graph when x=6    f(6) = -5

f(x) = 0  means the y value is 0  This occurs when x = 1 and x=5

Could someone find the expression?
KatRina [158]

Answer:

Total earned(in dollars) =2\ t+920

Step-by-step explanation:

Given:

Michael's hourly rate working as a tutor = $12 per hour

Michael's hourly rate working as a waiter = $10 per hour

Total number of hours worked by Michael for both jobs this month = 92

Let the number of hours Michael works as a tutor this month be =t hours.

∴ Number of hours Michael works as a waiter this month will be =(92-t) hours.

Amount earned by Michael this month from tutor job

⇒\textrm{Hourly rate}\times\textrm{Number of hours worked}

⇒12\times t

⇒\$12\ t

Amount earned by Michael this month from tutor job

⇒ \textrm{Hourly rate}\times\textrm{Number of hours worked}

⇒10\times (92-t)    

⇒\$(920-10\ t)     [Using distribution]

Total amount earned by Michael from both the jobs this month in dollars can be given as

⇒\textrm{Amount earned from tutor job+Amount earned from waiter job}

⇒12\ t+(920-10\ t)

⇒12\ t+920-10\ t

⇒2\ t+920

10. The perimeter of the rectangle below is 30 inches. Find the value of x.<br> 5x<br> X-3
Zigmanuir [339]
The answer is 3. This is because the perimeter is 30 so 5x+5x+x-3+x-3 = 30. Thus you have 12x-6=30 so x = 3
