F(x) is vertically stretched by a factor of 5/4 matches w/ f(x)-5/4
f(x) reflects the x axis matches w/ -f(x)
f(x) is translated 5/4 units up matches with f(x)+5/4
f(x) translated 5/4 to the left matches w/ f(x)-5/4
I didn't really know about this one but it seemed kind of easy, what was your first guesses and did you forget to put one more or was the question like that.
Hope this is right :) or if someone else has a different answer but in the meantime, good luck :)
Answer:
y=-8x+5
Step-by-step explanation:
The others have a slope of -2, 7, and 6, which is not as steep as -8.
A right triangle has two legs and a hypotenuse
a = shorter leg
b = longer leg
c = hypotenuse
We know b-a=4, or b = a+4
The Pythagorean theorem states:
a2 + b2 = c2
a2 + (a+4)2 = c2
a2 + (a+4)2 = 80
a2 + a2 + 8a + 16 = 80
Combine terms
2a2 + 8a - 64 = 0
Divide by 2
a2 + 4a - 32 = 0
Factor
(a+8)(a-4) = 0
a = 4, -8
We throw out the -8 solution because we can't have a negative measure.
So a = 4
b = 8
c = √80 = 4√5
The legs are 4 and 8.
