3x^2-1, x=2
3(2)^2-1
3(4)-1
12-1
11
When x=2, 3x^2-1=11.
An angle is the union of two rays with a common endpoint. The common endpoint of the rays is called the vertex of the angle, and the rays themselves are called the sides of the angle.
Answer:
x = 32
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(x+18) * 18 = 30^2
(x+18) * 18 = 900
Divide each side by 18
(x+18) * 18/18 = 900/18
(x+18) = 50
Subtract 18 from each side
x+18-18 = 50-18
x=32
For this case we have the following equation:
Where,
n: number of invitations:
c: cost in dollars
We note that the slope of the line for this case is:
The slope represents the cost of printing each of the invitations.
Therefore, it is false that the cost of printing each invitation is $ 5.50
Answer:
the following is not true:
A) each invitation costs $ 5.50 to print.
I hope this helped you! Good luck!
Answer:
y=6.7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
y+4=10.7
Step 2: Subtract 4 from both sides.
y+4−4=10.7−4
y=6.7
