Answer:
30% of 70 = 21
Step-by-step explanation:
21/70 = .3
.3=30%
If you know the radius of the circle do radius times 2.
Answer:
D
Step-by-step explanation:
We will use the 2 coordinates marked on the graph as the reference.
The coordinates are:
A(4,-2)
B(0,3)
We know that the standard form for equation of line is:
y = mx+c
where m is the slope of the equation
and c is the y-intercept.
Very clearly, the y-intercept is where the line intercepts the y line.
and in this case, y-intercept = c = 3.
Now we know that the equation of line is now
y = mx + 3
To find m, the slope, we can use the 2 above coordinates.
slope of line =
(Note: There is a 2nd way to find the slope in this case, let me know if you are interested to find out.)
Equation of line:
Therefore the answer is D.
The format of a line equation is y = mx + b
When two lines are parallel, their 'm' variables are equal.
Knowing this, the unknown line equation, so far, would look like this:
y = 9x + b
Since we know that the line equation goes through the point (2, 7)
7 = 18 + b
b = -11
y = 9x - 11
Answer:
48 units
b= 48 units
Step-by-step explanation:
pythag is
we have a and c
so substitute them in
now you can solve
subtract 196 from both sides
subtract
2500 - 196 = 2304
solve for the square root
square root of 2304= 48
therefore b= 48 units
