Answer:
X=18
Step-by-step explanation:
Isosceles means two sides are equal. In this case AC and BD are the same. So put both equations equal to each other and solve
Answer:
990 ways
Step-by-step explanation:
The total number of automobiles we have is 11.
Now, what this means is that for the first position , we shall be selecting 1 out of 11 automobiles, this can be done in 11 ways( 11C1 = 11!/(11-1)!1! = 11!/10!1! = 11 ways)
For the second position, since we have the first position already, the number of ways we can select the second position is selecting 1 out of available 10 and that can be done in 10 ways(10C1 ways = 10!9!1! = 10 ways)
For the third position, we have 9 automobiles and we want to select 1, this can be done in 9 ways(9C1 ways = 9!/8!1! = 9 ways)
Thus, the total number of ways the first three finishers come in = 11 * 10 * 9 = 990 ways
Answer:
y=-3x+9
Step-by-step explanation:
y=mx+b
m=slope
b=y-intercept
The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
From the graph, using the points (0, 0) and (3, 12):
y - 0 = [(12 - 0)/(3 - 0)](x - 0)
y = 4x
The equation for the graph passing through the points (0, 0) and (3, 12) is y = 4x.

First you need to multiply each side by 2
X - C. X - C = d * 2
-------- = d --->
2
Then add X from each side
C = d * 2 + X
