So
is the same as
and therefore
is
.
So.. the
minus
.
We can pull a 4 out of the 32 to make 4
as 16 times 2 is 32
We can pull a 2 out of the 8 to make 2
.
Now they have like bases, so to speak, and 4-2 is 2.
So the answer is 2
.
Answer: The equation of the trend line is y = -2x + 24.
First, we need to find the slope. The slope is the change in y over the change in x between the points. Our points move down 4 units while moving right 2 units. So our slope would be -4/2 or just -2.
Second, we need to find the y-intercept. We are lucky because the y-intercept can be see clearly in the graph. It is (0, 24).
We can put the slope and y-intercept together to get the equation:
y = -2x + 24.
Answer:
C
Step-by-step explanation:
So we have the equation:
And we want to solve for r.
So first, isolate the r variable. Divide both sides by dπ. So:
The right side cancels:
Take the square root of both sides:
We can rearrange the terms:
Our answer is C.
Answer:
16
Step-by-step explanation:
3x+(x-2)=10
4x=12
x=12/4=3
y=x-2=3-2=1
so, x=3 and y=1
