Answer: 29</h3>
========================================================
Explanation:
x = length of segment DC
The three triangles in that diagram are similar, which allows us to form this proportion below
BD/AD = AD/DC
Apply substitution and solve for x.
BD/AD = AD/DC
4/10 = 10/x
4x = 10*10 ... cross multiply
4x = 100
x = 100/4
x = 25
DC is 25 units long
Therefore,
BC = BD + DC = 4 + 25 = 29
Answer:
the transformed function becomes: g(x) = 5 x - 30
Step-by-step explanation:
When the function f(x) = x is shifted down by a factor of 6 we have the following transformation:
f(x) --> x - 6
After this, a vertical stretch by a factor of 5 should affect the full functional expression in the following way:
5 ( x - 6) = 5 x - 30
Therefore the transformed function becomes: g(x) = 5 x - 30
Answer:
Step-by-step explanation:
We can subtract a term from another if they have the same variable. Both and have the variable , so we can subtract them.
When subtracting these terms, we subtract the coefficients and keep the variable.
So:
Hope this helped!
