The picture in the attached figure
we know that
area of a circle=pi*r²
diameter=8 in
so
radius r=8/2----> 4 in
area=pi*4²-----> 3.14*4² in²
the answer is3.14*4² in²
I think it's the last one, i'm not sure though
Answer: d
Step-by-step explanation: just took the test
Answer: One solution
Step-by-step explanation:
y = 3x + 3
y = -2x + 3
-----------------------------------------------------------------------------------------------------------
To solve this, you need to understand a few things:
a) If two lines have the same slope but different y-intercepts, they are parallel when graphed and thus do not have any solutions
b) If two lines have the same slope and same y-intercepts, they are the same line when graphed and thus do not have infinitely many solutions
c) If two lines have different slopes (and/or y-intercepts), they have one solution
-----------------------------------------------------------------------------------------------------------
These two lines have different slopes but the same y-intercept (condition c)
So they have one solution
