What is the value of f(7)
2 answers:
F(7) means f(x) when x = 7. The x is replaced with 7.
So we'll replace every x with 7 to go from x = 7 to 3-x = 3-7 = -4
Put another way
f(x) = 3-x
f(7) = 3-7
f(7) = -4
Answer: -4
Answer. -4.
<span>*f - 3 = -5 (x-0) </span>
<span>f= -5x + 3 </span>
<span>*f - (-3)= -5 (x - 1) </span>
<span>f + 3 = -5x +4 </span>
<span>f= -5x+5 -3 </span>
<span>f= -5x+1</span>

Pythagorean theorem is formula we would use:
1.)
c^2=a^2+b^2
c^2=10^2+24^2
c^2=100+576
c^2=676
c= √676
c=26 in
2.)
c^2=7^2+14^2
c^2=49+196
c^2=245
c= √245
c~15.65 cm
Alternate interior angles I believe

Step-by-step explanation:
Very easy:
Find volume by formula: W*H*L
6*5*4=120
10*10*2=200
120+200=320 cubic inches for first question
