Answer

Step-by-step explanation:

Let x be Chris's age before, x+35 be Chris's age now.

2(x+35) = 35+7x

2x+70 = 35 +7x

35=5x

7=x

7+35=42

3x^2-3x<br> ----------- -3<br> x^2-9x<br> please give me the simplified answer + explanation

STatiana [176]

You want us to simplify $\frac{3x^2-3x}{x^2-9x}-3$

first, factor top and bottom
$3x^2-3x=3x(x-1)$
$x^2-9x=x(x-9)$

so we have
$\frac{3x(x-1)}{x(x-9)}-3=$
$\frac{3(x-1)}{x-9}-3$
we want to combine fractions so multiply 3 by $\frac{x-9}{x-9}$
$\frac{3(x-1)}{x-9}-\frac{3(x-9)}{x-9}=$
$\frac{3(x-1)-3(x-9)}{x-9}=$
$\frac{3x-3-3x+27}{x-9}=$
$\frac{24}{x-9}$

the simplified answer is $\frac{24}{x-9}$

Through: (4, -1), parallel to y = x - 1

NARA [144]

Answer:

The answer to your question is y = x - 5

Step-by-step explanation:

Data

Point = (4, -1)

line ║ to y = x - 1

Process

1.- Find the slope. The slope is the coefficient of the x.

y = 1x - 1

slope = m = 1

2.- Identify the values x1 and y1

x1 = 4 y1 = -1

3.- Find the equation of the line

y - y1 = m(x - x1)

-Substitution

y + 1 = 1(x - 4)

-Solve for y

y + 1 = x - 4

y = x - 4 - 1

-Result

y = x - 5

A campus program evenly enrolls undergraduate and graduate students. If a random sample of 5 students is selected from the progr

Bezzdna [24]

Answer:

The answer is "0.03125".

Step-by-step explanation:

Two types of undergraduates exist. Its chance for selecting the very first person who is part of degree studies will be 1/2. The probability will also be 1/2 for the 2nd person, as well as, the 3rd, 4th, and 5th person. For 5 random samples, the probability of the graduate therefore is

$\to \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{32}=0.03125$
