<span>1)
f(x) = x^2 + 2x
So lets replace all the x parts with (a-3) f(a-3) = (a-3)^2 + 2(a-3)
and the rest is just expanding it out from there.
</span>A: a^2-4a+3<span>

</span>2. If f(x0=x/x-3 and g(x)=2x-1, find (f-g)(x)
A: -2x^2+8x-3/x-3

3. If f(x)=x^2+1 and g(x)=1/x, find [f*g](x)
A:1/x^2 +1

4. Which equation best represents a line perpendicular to the graph of x+3y=9?
A:y=3x-1

5. Which of the following describes the graphs of 2x+5y=9 and 10x=4y+18?
A: perpendicular

6. Write the standard form of an equation of the line parallel to the graph of x-2y-6=0 and passing through A(-3,2)
 A: x-2y+7=0

How do I solve this? Step by step
shutvik [7]

Answer:

24.

Step-by-step explanation:

Substitute each instance of x with a 3.

That leaves us with 3^2 + 3x - 5 + 3^2 - 3x + 11.

Combine like terms.

2(3^2) + 6.

Simplify.

2(9) + 6

18 + 6

A line passes through the two given points. Is it vertical, horizontal, or neither?
Leviafan [203]

<u>Answer:</u>

A line passes through the two given points (5,2), (5,-2). The line is vertical line

<u>Solution:</u>

Given, two points are (5, 2) and (5, -2)

We have to find that a line that passes through the given two points is vertical or horizontal or neither.

First let us find the slope of the line that passes through given two points.

So, slope of line m =\frac{y_{2}-y_{1}}{x_{2}-x_{2}} \text { where, }\left(x_{1}, y_{1}\right) \text { and }\left(x_{2}, y_{2}\right) \text { are two points on line. }

So slope of our line =\frac{-2-2}{5-5}=\frac{-4}{0} = undefined

Here slope of our line is undefined which means it is parallel to the y – axis.

Hence, line passing through given points is vertical line

Part A
blueberries
2/8 × 6/1(drinks) = 12/8cups
banana slice
5/8 × 6/1(drinks) = 30/8cups

30/8 + 12/8 = 42/8 cups<---- that's the answer

Part B
yogurt
4/8 × 6/1 (drinks) = 24/8 cups of yogurt <---
and 6 drinks × 1 cups of ice = 6 cups of ice <---
