Answer:

The correct answer is B. 9

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

The correct answer is B. 9

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:

First, we need to calculate the variable income per job:

First job= 450 - 150= 300

Second job= 675 - 150= 525

Now, the hourly rate:

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

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

$=\frac{364}{1820}=0.2$
