Answer:
x = 9
Step-by-step explanation:
The big triangle is similar to smaller one so we can use the side lengths' proportion to find x:
7/4 = (x-3)+8/8
7/4 = (x+5)/8 cross multiply expressions
56 = 4x + 20 subtract 20 from both sides
36 = 4x divide both sides by 4
9 = x
Just plugin the values of k and m into the equations listed so that D to origin = B to origin and A to origin = C to origin.
The answer is c.
16ft= 192 in
8ft= 96 in
192/36= 96/16 = 6
Your drawing is 1/6 of the actual billboard
Answer:
7/3
Step-by-step explanation:
The slope is found by dividing the difference in the y-coordinates by the difference in the x-coordinates.
Here, the difference in the y-coordinates is: 4 - (-3) = 4 + 3 = 7. The difference in the x-coordinates is: 3 - 0 = 3.
Dividing 7 by 3, we get a slope of 7/3.
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1
Step-by-step explanation: that is your anwser
