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 $y=6$

Suppose that your boss must choose three employees in your office to attend a conference in Jamaica. Because all 17 of you want

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:

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

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

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