Answer: x=4
Step-by-step explanation:
similar triangle so corresponding parts are similar
cross multiply
70 = 20x-10
80 = 20x
x = 4
9514 1404 393
Answer:
(b) 48
Step-by-step explanation:
In this geometry, the altitude (x) is the root of the product of the segments of the hypotenuse.
x = √(36·64) = √36×√64 = 6×8
x = 48
_____
All of the triangles are similar, so the ratios of corresponding sides are the same.
short side/long side = x/64 = 36/x
x^2 = (64)(36) . . . . as above
Answer:
xy = 3
Step-by-step explanation:
The expression to be evaluated is:
By some algebraic handling:
Where:
There is one possible solution:
x = 3, y = 1
And consequently,
xy = 3
To put it in slope intercept form, you want to solve for y.
5y = -6x + 50
y = -6/5x + 10
So, your slope is -6/5 (or -1.2) and your y-intercept is +10.
Do you have a (a,b,c,d) type of answer?
if yes it would be c, if no... Then uh good luck
