Okay, this is a case of substitution:
3x + y = 13 correct?
-3x -3x
So: y = 13 - 3x
So: 3x +(13-3x)=13
and this is interchangeable, so x and y = all positive numbers
aka. 6x + 2(13-3x) = 26
it does not matter what numbers x and y are as long as they positive
Answer:
731
Step-by-step explanation:
to find out the percent you multiply 340 by 115% which will look like this 340 times 1.15 equals to 391
to find out how many students will enroll next year you add 340 and 391 and it equals to 731.
-16t^2 represent the position on the graph on the negative side.
According to the statement
we have given equation is h(t)=5+100t-16t^2 -(1)
And we have to find representation of -16t^2
we know that the equation number (1) represent the Quadratic Equation
And in this we have to solve the Quadratic Equation and find the representation of the given terms. then
h(t)=5+100t-16t^2
5+100t-16t^2 = 0
16t^2 -100t-5 = 0
In this equation 16t^2 represent the equation on the graph.
It means that it shows the position on the graph.
Overall, -16t^2 represent the position on the graph on the negative side.
