Answer:
a) mCD=7
b) mCF=7
c) mFD=7
d) F(2,-14)
Step-by-step explanation:
Let the coordinates of C and D be (4,0) and (0,-28) respectively and F is the midpoint of CD
a) mCD
Slope formula
mCD=7
b) mCF
mCF=mCD
Hence mCF=7
c) mFD
mFD=mCD
Hence mFD=7
d) Coordinates of F : mid point formula
Mid points Formula
coordinates of F are (2,-14)
<span>To put the unknown in other words, we are to determine a fraction that has a denominator of 10 which should be equivalent to 3/5. If we let x be the numerator of the second fraction such that we form a proportion out of the two fractions that is,
3/5 = x/10
The value of x is calculated as below,
x = (3)(10) / 5 = 6

I hope I helped! Also, one thing when you adding decimals or multiplying them, pretend the decimal point isn't even there. Then, once you have your answer, you just add the decimal in the middle. Basically just adding like in first grade! Super easy and I hope I helped!
