Answer:

<u>The correct answer is B. 9</u>

Step-by-step explanation:

Let's solve for y in the equation below, given that x = 2

y = 6x - 3

Substituting x in the equation, this way:

y = 6 * 2 - 3

y = 12 - 3

y = 9

The value of y is 9 when x is 2

<u>The correct answer is B. 9</u>

Thanks for the help! Been stuck on this one for a little while.

Answer:

B. \sqrt{14}

Step-by-step explanation:

Since 3.74 is rounded to the hundredths place, it is not the ideal exact solution for m^2 = 14.

To solve for m you would have to square root m and 14, which gives you \sqrt{14}. This is the best answer for the problem.

5) Mario owns a plumbing business. He charges an hourly rate plus a onetime set up fee. His first job was 4 hours and he charged
Wittaler [7]

Answer:

Results are below.

Step-by-step explanation:

<u>First, we need to calculate the variable income per job:</u>

<u />

First job= 450 - 150= 300

Second job= 675 - 150= 525

<u>Now, the hourly rate:</u>

<u></u>

Hourly rate= total variable income / number of hours

First job= 300 / 4= $75

Second job= 525 / 3= $175

It is probably that the second job was 7 hours long. If not, he doesn't charge the same amount per hour

Suppose that a nonnegative integer solution to the equation u + v + w + x + y = 12, thought of as a 5-tuple (u,v,w,x,y) is chose
son4ous [18]

Answer:0.2

Step-by-step explanation:

Given

u+v+w+x+y=12

total solution for u+v+w+x+y =12 is given by ^{n+r-1}C_{r-1}

here n=12\ r=5

i.e. ^{12+5-1}C_{5-1}=^{16}C_4

For u=1

1+v+w+x+y=12

v+w+x+y=11

no of solutions for this equation is

^{11+4-1}C_{4-1}=^{14}C_3

if one solution is chosen at random Probability that u=1

=\frac{^{14}C_3}{^{16}C_4}

=\frac{364}{1820}=0.2
