Step-by-step explanation:
I’m very confused
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.
Rise over run is another term for slope, with we can use to derive a linear equation.
The term rise over run in technical terms is the change of y over the change of x.
To find the rise over run, subtract the y terms and divide that by the x terms.

You can use this to derive a linear equation as earlier mentioned by plugging in given points.
For example, a line passes through (3,4) with a rise over run of 3.




So therefore the y intercept is -5, and the equation is
