She sold 25 t-shirts cuz she made $75 and spent $25 which means she sold $100 worth of shirts which divided by $4 a piece is 25 t-shirts.
Answer:
4x4 - x3 + 7x2 + 13x - 10
Step-by-step explanation:
(((4•(x4))+7x2)+6x)-(x3-7x+10)
((22x4 + 7x2) + 6x) - (x3 - 7x + 10)
3.1 Find roots (zeroes) of : F(x) = 4x4-x3+7x2+13x-10
Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 4 and the Trailing Constant is -10.
of the Leading Coefficient : 1,2 ,4
of the Trailing Constant : 1 ,2 ,5 ,10
Final result :
4x4 - x3 + 7x2 + 13x - 10
hope this helps:)sorry if it doesnt
Use the equation y sub 2-y sub 2 over x sub 2-y sub 1
-1 is the answer
See the attachment for a labeled graph.

I find it convenient to use "technology" to draw the graph. A spreadsheet, graphing calculator, or on-line graphing program can do this for you.
This is a straight line with an undefined slope so
y = 8
