(x+2) is the answer.
you distribute (x+2)^2 then cancel out 'likes', which leaves you with (x+2)

Answer:

B. y= 2x–15

Step-by-step explanation:

The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15

"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)

(8, 1) and (10, 5)

x in the first bracket is 8 and x in the second bracket is 10.

y in the first bracket is 1 and y in the second bracket is 5.

When this equation is applied to find the value for y we get:

y= 2x-15

y= 2(8)-15

y= 16-15

y= 1

y= 2x-15

y= 2(10)-15

y= 20-15

y= 5

We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)

Answer:

f(g(x)) = 2x +(-5)

Step-by-step explanation:

Put the argument value into the function and simplify the result.

f(g(x)) = f(x -3) = 2(x- 3) +1 = 2x -6 +1

f(g(x)) = 2x +(-5)

Solve. Enter your answer as a mixed number. The driving distance from the sports arena to Kristina's house is 11 7 10 miles. The

Answer: $6\frac{1}{2} miles$

Step-by-step explanation:

From the sports arena to Kristina's house = $11\frac{7}{10}miles$

From the sports arena to Luke's house = $5\frac{2}{10} miles$

Subtract Luke from Kristina

$5\frac{2}{10}-11\frac{7}{10}$

There's a confusing but easy way to solve this. However, I'm going to convert into improper fractions to make it easier.

To convert to improper fraction, take the whole number, multiply it by the denominator and add it to the numerator. All over the same denominator.

$\frac{5*10+2}{10} -\frac{11*10+7}{10}$

$\frac{50+2}{10}-\frac{110+7}{10}\\\frac{52}{10}-\frac{117}{10}$

Subtract them.

$\frac{52-117}{10}$

$-\frac{65}{10}$

Convert to mixed number by dividing.

65/10=6

----

The 6 is the whole number, 5 the numerator and 10 the denominator. Remember the negative sign that we had.

$6\frac{5}{10}$

5 and 10 can be simplified

5/5=1

10/5=2

Our final answer would be:

$6\frac{1}{2}$
