Answer:
Cubic Function
Step-by-step explanation:
In mathematics, a cubic function is a function of the form f(x)=ax^3+bx^2+cx+d where the coefficients a, b, c, and d are real numbers, and the variable x takes real values, and a ≠ 0. In other words, it is both a polynomial function of degree three, and a real function.
Answer:
Step-by-step explanation:
8441/21= 401 r 20
5s + 5l = 155, 10s + 12l = 346
Solve for s in the first equation.
5s = 155 - 5l
s = 31 - l
Substitute s into the second equation.
10(31 - l) + 12l = 346
310 - 10l + 12l = 346
310 + 2l = 346
2l = 36
l = 18
Substitute l into the first equation.
5s + 5(18) = 155
5s + 90 = 155
5s = 65
s = 13
s = 13, l = 18
Answer:
The two numbers are 52 and 12.
Step-by-step explanation:
x+y=64
x=16+3y
Now, substitute the second equation into the first one.
16+3y+y=64
16+4y=64
4y=48
y=12
Substitute 12 into one of the equations in order to find x.
x=16+3(12)
x=16+36
x=52
Answer: The price for the gloves were $5 each and the price of the hats were $7 each.
Step-by-step explanation:
2g + 4h = 38 solve by elimination
3g + 5h = 50
-3(2g + 4h) = 38(-3) -6g -12h= -114
2 (3g + 5h)= 50(2) 6g + 10h =100
0 + -2h= -14
h= 7
-6g -12(7)=-114
-6g -84 = -114
+ 84 +84
-6g =-30
g= 5
