Answer:
Yes, the point (2,6) is on the graph of y=3x
Step-by-step explanation:
y = 3x
For the order pair (2,6)
substitute with x = 2 at the given function.
3x = 3 * 2 = 6
So, the point (2,6) on the graph of y=3x
Also, see the attached figure.
Use the formula
Area= base times height.
You're given that area =300cm^2 and base=20 cm.
Plug these into the equation to get 300=20 x height. Now, you just need to solve for height. To do this, you need to undo the multiplication of b x h by dividing the area by the base.
So, h = 300/20
Simplify for an answer of 15.
So the original area is 300*150 (or 45000 ft^2), but now the new area is (300+3y)(150+3y).
The polynomial in standard form would be 45000+900y+450y+9y^2=45000+1350y+9y^2
But the proper way to write it is 9y^2+1350y+45000
When y=4, we get 9(4^2)+1350(4)+45000=9(16)+54000+45000=144+99000=99144
So the new area would be 99144 ft^2
Hope this helped!
This is not a quadratic equation.
It is a cubic equation.
X1 = 4
X2 = -5
X3 = -4
<u>Answer </u>
B. f(x) = - (y/x)⁵
<u>Explanation</u>
A negative power means the reciprocal of that number raised to the positive value .
For example, a⁻ⁿ = 1/aⁿ
So, for the question above.
f(x) = -(x/y)⁻⁵
= - 1/(x/y)⁵
= - (y/x)⁵
