<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

Equilateral triangle ABC has a perimeter of 96 millimeters. A perpendicular bisector is drawn from angle A to side BC at point M
a_sh-v [17]

Answer:

16 mm  

Step-by-step explanation:

Since ABC is an equilateral triangle, all three sides are the same length.  The perimeter is found by adding together all of these equal sides; letting x represent the length of a side of the triangle, this gives us

x + x + x = 96

Combining like terms,

3x = 96

Dividing both sides by 3,

3x/3 = 96/3

x = 32

Since AM is a perpendicular bisector, it splits BC into two congruent sections. This means the length of MC, half of BC, will be 32/2 = 16.

Find the equation for the linear function that passes through the points ( see photo)
Sidana [21]

Answer:

f(x) = (-4/5)*x + 4

Step-by-step explanation:

The line which passes through these points will decrease y by 12 for every x increase of 15. This is the same as decreasing y by 4 for every x increase of 5. This means the slope (rise over run) is -4/5. If this is applied to the first point to find what y is at 0, then the point (0, 4) is on the line.

This means that f(x) = (-4/5)*x + 4
