Its quite simple. Its just subtraction.
18 hotdogs - 12 hotdog buns = 6 hotdug buns still needed
Try to convert them into equivalent fractions. The comon multiple is 80 so convert them.
3/8 = 30/80
4/10 = 32/80
4/10 is greater
Ab= 28
(bc)^3= -42875
-3c^2= 225
I hope it's right..
Option B:
Option D:
Solution:
<em><u>Polynomial definition:</u></em>
A polynomial can have constants, variables and exponents and fractional coefficient.
A polynomial cannot have fractional exponent, negative exponent and never division by a variable.
To select the expressions that would be considered as a polynomial.
Option A:
√x is not, because the exponent is ½. Fractional exponents are not polynomials.
This is not a polynomial.
Option B:
A polynomial can have constants, variables and exponents.
This is a polynomial.
Option C:
Fractional exponents are not polynomials.
This is not a polynomial.
Option D:
Fractional coefficients are allowed.
This is a polynomial.
Hence and are polynomial.
Answer:
Graph 1:
y-intercept = 7
Slope = -1/2 <--- (It's a fraction) (-1 over 2)
Equation: y = -1/2x + 7
________________________________
Graph 2:
y-intercept = 4
Slope = 5/6 <--- (It's a fraction) (5 over 6)
Equation: y = 5/6x + 4
_________________________________
Graph 3:
y-intercept = 9
Slope = -5/7 <--- (It's a fraction) (-5 over 7)
Equation: y = -5/7x + 9
Hope this Helps :)
