The product of 3 and m is 54
3m = 54
Is this a function:
{ (3,2) (2,5) (-3, 7) (5,2) }
Yes this is a function
identify the slope and y-intercept:
y= -1/2x + 5
m=?
b=?
m = -1/2. b = 5
What other math class does Ms. Arreaga teach?
Evaluate if a = 2 and b = 3
2a + b =
7
Solve for x:
2x + 6 = 24
x = 9
If the graph if an equation forms a circle is that a function yes or no, explain why?
No because it fails the vertical line test.
A line passes through the point (2, -3) and has a slope of 7.
Write the equation in POINT SLOPE FORM.
y + 3 = 7(x -2)
Slope intercept form is ?
Combine Like Terms:
2x + 7 - 5x +2
-3x + 9
Solve for m:
2m + 30 = 17m
m=2
What is the domain and range?
{ (x, 5) ( 3, 2) ( m, -7)}
what is a positive feedback loop
Find the slope between the two points:
( 5, -2) and ( -8,6)
m = -8/13
Point Slope Form is ?
(y-y1) = m(x - x1)
Distribute
2(3x - 2 + 2y)
6x - 6 + 4y
Solve for x :
3(x + 5) = 36
x = 7
f(x) = -3x + 2
Find f (6)
f(6) = -16
Graph the equation:
y= -3/4x - 1
Ms. Arreaga will check your work for this
My favorite thing to drink is?
COFFEE
Simplify:
-5( x + 3) - 15 + 2x
-3x - 30
Solve for y:
-3(y + 2) = 5(2+y)
y = -2
g(x) = -2x2 + 7
Find g (2)
g(2) = -9
Find the equation of the line if it passes through the POINT ( 2 ,5) and has a SLOPE of 1/2.
y = 1/2x + 4
