Step-by-step explanation:

  • x^2+10x=0

(x+10)(x-0)=0

x=-10 and x=0

  • x=-10 in x^2+10x+h=h

(-10)^2+10(-10)+h=h

100-100+h=h

0=0

  • x=0 inx^2+10x+h =h

0^2+10(0)+h=h

0+h=h

0=0

Lucy had math and reading homework tonight. Lucy can solve each math problem in 5 minutes and she can read each page in 2.5 minu
drek231 [11]

Answer:

x=18,y=6,  graph is there for reference.

Step-by-step explanation:

Given,

x is the number of math problem Lucy solved.

y is the number of  pages she read.

She can do each math problem in  5 minutes, therefore she can solve x number of questions into 5 \times x=5x minutes.

She can read each page in 2.5 minutes, therefore she can read y pages in 2.5y minutes.

As per given detail,

5x+2.5y=105 equation 1.

And,

It is given that number of math problems Lucy solved is 3 times the number of pages she read.

x=3y equation 2.

We need to find x and y intercept of each of the equation to graph them.

For x-intercept put y=0

We will get x=\frac{105}{5} =21

Thus the point is (21,0)

Let us find y-intercept by assuming x=0

we get y=\frac{105}{2.5} =42

Thus the point is (42,0)

Join these two points.

Similarly considering the other equation x=3y

Here x-intercept would be at y=0

We will get x=0

Thus the point is (0,0)

Let us assume on more point, say x=30 , we get y=10

Thus the point is (30,10)

Join these two points.

We will get a point of intersection at (18,6)

Thus x=18 and y=6

Pani-rosa [81]

Answer:

P(You\ n\ Anna\ n\ Kevin) = \frac{1}{4913}

Step-by-step explanation:

Given

Total\ Employees = 17

To\ Select = 3

Required

Determine the probability of selecting You, Anna and Kevin

Assuming the selection process is fair;

Each employee has a probability of;

Probability = \frac{1}{17}

So:

P(You\ n\ Anna\ n\ Kevin) = P(You) * P(Anna) * P(Kevin)

P(You\ n\ Anna\ n\ Kevin) = \frac{1}{17} * \frac{1}{17} * \frac{1}{17}

P(You\ n\ Anna\ n\ Kevin) = \frac{1}{4913}
