Answer:

X=15

Step-by-step explanation:

Yes, you are right.

The given equation is

X+U=25

If U=10, then we substitute to obtain:

X+10=25

Subtract 10 from both sides to get:

X=25-10

Simplify to get:

X=15

Write an equation in slope-intercept form for each graph shown.<br><br><br> Please help!!!!!!!
stiv31 [10]

Answer:

y = 2x-3

Step-by-step explanation:

We have 2 points so we can find the slope

m = (y2-y1)/(x2-x1)

   = (1--3)/(2-0)

   = (1+3)/(2-0)

   =4/2

   = 2

The y intercept (where x=0) is -3

We can use the slope intercept form of the equation

y= mx+b  where m is the slope and b is the y intercept

y = 2x-3

Jlenok [28]

Answer:

Required Probability=\frac{^{6670}C_{20}}{^{40000}C_{20}}

Step-by-step explanation:

We have been given the total  40,000 words

And the words that started with letter T is 6,670

We need to find the probability of the words beginning with T

Words beginning with T will be ^{6670}C_{20}

Total words after choosing 20 unique words would be: ^{40000C_{20}

Probability=\frac{\text{words beginning with T}}{\text{total words}}

Probability=\frac{^{6670}C_{20}}{^{40000}C_{20}}

Hence,

Required Probability=\frac{^{6670}C_{20}}{^{40000}C_{20}}
