Answer:
y=-11.88x-39.93
Step-by-step explanation:
Plot the data
on the coordinate plane using graphing calculator. Then use linear approximation y=ax+b and determine that a=-11.88, b=-39.93.
The line that best fits these data is
Equation: <span>3b+4b^2-a^3
Given: </span><span>a=3 & b=-5
Plug 3 in for (a) and -5 in for (b):
</span><span>3(-5)+4(-5)^2-(3)^3
</span>
Now follow PEMDAS:
<span>3(-5) + 4(-5)^2 - (3)^3
</span>-15 + 4(-5)^2 - (3)^3
-15 + 100 - (3)^3
-15 + 100 - 27
85 - 27
58
the asnwer is 58.
Answer: c and d
Step-by-step explanation: I took the usa test prep
A) you cannot combined square roots if the radicands aren't the same.
Its like variables. You can only add like terms. IE You cannot add 2x +3y.
Its the only rule that applies to the problem.
