Answer:
a) x=0, x=1
b)x=0, x=4/3
Step-by-step explanation:
I didnt use the graph, just used algebra. For part a, you can find the answers using the graph by looking at the value of x when y = whatever value they give.
A)
3x²-3x+2=2
3x²-3x+0
x(3x-3)=0
For the product of two things to equal zero, one of them has to be zero. For example, if ab=0, then either a or b (or both) are zero.
Therefore..
x=0
or 3x-3=0, ∴x=1
b)
3x²-3x-1 = x-1
3x²-4x=0
x(3x-4)=0
∴x=0, x=4/3
Answer:
x = 60°
Step-by-step explanation:
G= 90°
30 + 90 = 120
180 - 120 = 60
Okay i answered by comment but now i can make an official answer here:
a) i got 5,828.6 grams / about 13lb
b) i got 273,391.48$
hope this helps!
Step 1: Add together the known angles.
Step 2: Subtract the sum from 180°.
