Find f(10)
3x + 2y = 16
7x + y = 19
y = 2x - 3
x = 2y - 3
x = 3 - 2y
x = 33 - 2y
2x-y=4 and y=-2x+8.
What is the value of x in the solution for this system?
(-4,-5) (4,5) slope = _____
11 - 3x = 44
x: -2 -1 0 1 2 3
-------------------------------
y: -3 0 3 6 9 12

Force and acceleration are related by the equations F= ma, where m is the mass and a is the acceleration of the object. Which equation gives m in terms of F and a?
m = Fa
m = F/a
m = a/F
m = Fma

Internet Company A charges $5 a month plus $0.05 per minute, x. Internet Company B charges $0.10 per minute, but does not charge a start-up fee like Company A does. Which function represents the difference in cost between Company A and Company B?
f(x) = 5x - 0.05
f(x) = 5x + 0.05
f(x) = 0.05x - 5
f(x) = -0.05x + 5
Sara did an experiment to compare two methods of cooling an object. The results are shown in the table given.
Which statement best describes her results?
The temperature using Method 1 changed exponentially.
The temperature using Method 1 changed at a constant rate.
The temperature using Method 2 changed exponentially.
The temperature using Method 2 changed at a constant rate.
The boiling point of water, T(measured in degrees), at an altitude, a (measured in feet), is modeled by the function T(a)= −0.0018a + 212. In terms of altitude and temperature, which statement described the meaning of the y - intercept.
The boiling point of water at an altitude of -0.0018 feet is 212 degrees.
The boiling point of water at an altitude of 0 is 212 degrees.
The boiling point of water at an altitude of 0 is 211.998 degrees.
The boiling point of water at an altitude of 212 feet is -0.0018 degrees.
(3 - 2x + 2x2) - (4x - 5 + 3x2)
-3x2( 7x2 - x + 4)
f(x) = -x2 - 4x + 12.
The length of a rectangle is 6 meters more than the width. The area is 72 square meters. Find the length and width.
Length = 6, Width = 12
Length = 18, Width = 4
Length = 12, Width = 6
Length = 4, Width = 6
