x is greater than 12
Which side should be shaded (y or g) for the linear inequality y > 1 + 2x
y is "greater than" 1 + 2x
Shade UP from 1
THE YELLOW
Write the perimeter of the quadrilateral as an expression in simplest terms.
-5x + 14
Solve for x and y
x + y = 88
x - y = 12
x = 50
y = 38
Describe the initial value of the account and the interest earned.
f(x) = 3500(1 + 0.027)^x
Initial Value: 3500
Interest earned: 2.7%
Solve for solutions of x.
3x < 2 + x
x < 1
x can be any value less than 1
Which section holds the solution to the system?
y > 2x + 5 y < -1x
Area 3
It has both shading (green & orange) because it is holds solutions to BOTH inequalities
Write the perimeter as an expression in simplest terms.
2x^2+16x-16
Solve for x and y.
3x + 5y = 7
x + y = 1
x = -1
y = 2
The local pond had 12 frogs in April and the frog population doubled every month!
How many frogs would there be in December?
F(m) = 12(2)^x
F(8) = 12(2)^8
F(8) = 3072
What rule takes effect when we multiply or divide with a negative in inequalities?
-5x > 10
Me must flip the inequality symbol
because negative values work the OPPOSITE that positives values work.
The perimeter is equivalent to 5x + 8. Write an equation to solve for x.
x^2+5x+4=5x+8
x^2-4=0
(x+2)(x-2)=0
x=-2 x=2
Solve by substitution for x and y
3x - 8y = -56
y= 2x + 7
x = 0
y = 7
Describe the initial value and the percent change.
g(x) = 3460(0.71)^x
Initial Value: 3460
Percent Change: a decrease of 29%
