Which equation represents a linear function? Equation 1: y = 2x2 + 1 Equation 2: y = 8x + 1 Equation 3: y = 5x3 – 1 Equation 4: y2 = 4x – 1
2 answers:
Equation 2 is the only linear one due to the fact that there is no exponent on the x or y values.
Answer:
Equation 2:
Step-by-step explanation:
A linear function or equation is one in which the variables involved have no exponents other than 1.
the options are:
Equation 1:
Equation 2:
Equation 3:
Equation 4:
Equation 1 has a quadratic exponent, the same for Equation 4.
And Equation 3 has a cubic exponent.
So the only equation that is linear is the Equation 2, because there are no exponents other than 1 in the expression.

Answer:
-18
Step-by-step explanation:
Essentially the same as (-6) - 12
Answer:
The answer is B.
Step-by-step explanation:
Its B because in the problem it says $12 per yard which means it would be 12y. The 40 Rupesh already had so just add it and it would be 12y+ 40. The key word "At least" results into the sign being greater than or equal to. So the final answer would be 12y+40 148.
Answer:
256
Step-by-step explanation:
any number to the 0 power equals 1, so r^0 equals 1
then, you have (4(1))^4
4×1=4
4^4=256
