X^2 + y^2 -4x27 (the numbers in bold means the multiplying a negative and a positive equals a negative)
x^2 + y^2 -(4x27) = x^2 + y^2 -108
Answer:
3^2
Step-by-step explanation: When the bases of two exponents are the same (in this case, they are both 3), and they are being multiplied, then their powers will be added together. -4 plus 6 is 2, so the new exponent will be 3^2.
If you multiply or divide two positive numbers together the answer will be positive.
If you multiply or divide two negative numbers together the answer will be positive.
If you multiply or divide a negative number and a positive number together the answer will be negative.
If there are 108 students, and the vans can hold up to 5 students, then you would need 22 vans.
If you were to divide 108 by 5, then you would get 21.3 . That 3 is the remaining children, therefore, to fit them in the trip, you would need another van, hence, 22 vans. The van that is not full would have 3 children in it.
Traci will be 360 miles in 12 hours if the linear equation y = 30x describes how far from home Traci is as she drives from Dallas to Anchorage and the equation of the graph is linear.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have a linear equation:
y = 30x
Here, x represent the number of hours and y represent the number of miles.
When x = 12 hours then
y = 30(12) = 360 miles
If draw the graph the equation y = 30x, it will be a linear equation.
(refer attached picture)
Thus, Traci will be 360 miles in 12 hours if the linear equation y = 30x describes how far from home Traci is as she drives from Dallas to Anchorage and the equation of the graph is linear.
