1If f(x) = 3x + 1, find f(2)[blank_start]10[blank_end]
- A10
2If f(x)=g(x)-2 and g(x)=3x+1. Find f (1/2)[blank_start]1/2[blank_end]
- A1/2
3If f(x)=(x-3)/(x+2) and g(x)=x/x-1. Find f (g (x))[blank_start](-2x+3)/(3x-2)[blank_end]
- A(-2x+3)/(3x-2)
4Let f (x) = 2x^2 + 3x - 5 and g (x)=4. Find f○g [blank_start]39[blank_end]
- A39
5Which value is not contained in the systems of equations?
a + 5b - c = -20
4a -5b +4c = 19
-a -5b -c = 2- A2
- B-2
- C3
- D-3
6Solve the systems of equations
x=3
5x +4y= -9
-x +4y -2z= -25 ➡[blank_start](3, -6, -1)[blank_end]- A(3, -6, -1)
7What's the solution of the system
2x-4y+2z=4
5x-3y+5z=-4
4x-5y+2z=8➡[blank_start](1, -2, -3)[blank_end]- A(1, -2, -3)
8Pick the correct solutions to the system
- A(-5,0)
- B(1,6)
- C(5,0)
- D(-1,-6)
- E(-6,1)
9Which is a solution to the system?
- A(2,2)
- B(-2,2)
- C(0,2)
- D(-2,0)
10Pick the correct solutions to the system
x^2 + y^2 = 5
x + y = 3- A(1,2)
- B(2,1)
- C(-1,2)
- D(-2,-1)
11What's the solution to the system
9x^2 + y^2 = 9
3x - y = 3. ➡[blank_start](0,-3)(1,0)[blank_end]- A(0,-3)(1,0)
12Write the inverse of y= 12x -3➡[blank_start]y=(1/12)x + (1/4)[blank_end]
- Ay=(1/12)x + (1/4)
13Write the inverse of y= -2x + 10 in y= b - mx form➡[blank_start]y=5- (1/2)x[blank_end]
- Ay=5- (1/2)x
14Write y= 2x+ 13 in point slope form➡[blank_start]y - 5 = 2 (x+4)[blank_end]
- Ay - 5 = 2 (x+4)
15Write y = 2x - 11 in point - slope form➡[blank_start]y + 3 = 2 (x-4)[blank_end]
- Ay + 3 = 2 (x-4)
16What's the inverse of an equation that passes through (2,1)(3,6)?➡ [blank_start]y = (1/5)x + (9/5)[blank_end]
- Ay = (1/5)x + (9/5)
