Answer:
C
Step-by-step explanation:
A "zero" of a function is an input value that makes the function value equal zero. On the graph these input values are -3 and 1; you can see that the function values are zero in both cases. C is correct.
Answer:
Math is far from my strongsuite, but try 18x?
Step-by-step explanation:
I'm assuming "For x=-4" means that x is equal to -4. X is squared by 2 meaning that it would essentially be "-4×-4", which is equal to positive 16. 16+2x should be equal to 18x. I hope I'm correct about that XD
Answer:
Malcolm's maximum speed is
Ravi's maximum speed is
Step-by-step explanation:
Notice that this is a problem with two unknowns: the max speed of Malcolm (let's name this "M"), and the max speed of Ravi (let's name this R). So we need to build two equations with them, based on the information given.
Equation 1: based on the phrase "The average of their maximum speeds was 260 km/h" we write the equation for average (addition of both speeds, divided by 2, equal 260 km/h:
Equation 2; based on the phrase: "If doubled, Malcolm's max speed would be 80 km/h more than Ravi's max speed"
We can now use for example substitution to solve the system of equations
From the second equation we created, we can solve for R in terms on M:
and use it as substitution in the first equation:
And now use this value of M in the substitution equation to solve for R;
