B = 7
7 x 6 = 42
42 + 6 = 48.
Remember x is x and f(x) is same thing as y.
f(5) = 4
It is same thing as saying, when x = 5, y aka f(x) should be 4. Aka the point (5,4)
Let’s look at D, if x =5 then f(x)=5? No, it should equal 4. So this is wrong. It is also not linear. So NOT D
Lets look at C, if x =5 then
1/5(5)+3 =
5/5 + 3 =
1+3 =
4
So, f(x) aka y = 4. Is this correct? Yes when x =5, y indeed should equal 4, but it is not linear. So NOT C
Lets look at B, if x=5 then,
2^5 -28 =
32 - 28 =
4
So, f(x) aka y = 4. Is this correct? Yes when x =5, y indeed should equal 4, AND it is linear SO THE ANSWER IS B
Check A too, it gets y=14 so thats wrong as it is not 4.
16000x9%x5 is $7200 #1 is $7200
16000x9%x3 is $2400 soo 7200-2400 is 4800 sooo
#1 is $7200
#2 is he or she will save $4800
Answer:
C: 1/2x +7
Step-by-step explanation:
No it is equivalent to 0.4. All you have to do is divide 2 by 5.
