Answer:
c = 5
Step-by-step explanation:
We can find a, b, c by filling in values from the table into the equation:
17 = a(2²) +b(2) +c
32 = a(3²) +b(3) +c
53 = a(4²) +b(4) +c
__
There are numerous ways to solve 3 linear equations in 3 unknowns. We can use elimination.
Subtracting the first equation from each of the other two, we get ...
15 = 5a +b . . . . . . . . . note that c has been eliminated from the equations
36 = 12a +2b
Subtracting twice the first from the second gives ...
(12a +2b) -2(5a +b) = 36 -2(15)
2a = 6
a = 3
__
Now that we have a value for "a", we can "back substitute" into the equations to find "b" and "c".
Substituting this into 15 = ..., we get ...
15 = 5(3) +b
0 = b
And substituting for "a" and "b" in the first original equation gives ...
17 = 4(3) +c
5 = c
The value of c, the constant of the function, is 5.
Answer:
y=5
Step-by-step explanation:
4(y-6)=-4
4y-24=-4
+24 +24
4y=20
y=5
Awesome question!
1.) You have 80 points and you want to take away 5% of them.
- 5% is 1/2 of 10%. And remember your number places. So 80 has 0 in the ones and an 8 in the tens place. Move the decimal over to the left 1 time and you get 8.00 Now you have 10% of 80. And 5% is one half of 10%, so 8/2 is 4.
4 is 5% of 80. And you take away 4 from 80 and end up with 76.
Hope I explained this for ya!
