Answer:
- <u><em>x-int: (2, 0)</em></u>
- <u><em>y-int: (0, -5)</em></u>
To find the x-intercept, substitute in 0 for y.
To find the y-intercept, substitute in 0 for x.

Step-by-step explanation:
ANSWER: You will pay $385 for a item with original price of $700 when discounted 45%. In this example, if you buy an item at $700 with 45% discount, you will pay 700 - 315 = 385 dollars
Answer:
Zeros of the given function are x=5 and x=-1.
Step-by-step explanation:
f(x)=x^2-4x-5
f(x)=x^2+1x-5x-5
f(x)=x(x+1)-5(x+1)
f(x)=(x-5)(x+1)
To find zeros, we need to set f(x)=0
0=(x-5)(x+1)
0=(x-5) or 0=(x+1)
0=x-5 or 0=x+1
5=x or -1=x
Hence zeros of the given function are x=5 and x=-1.
We can plug some random numbers like x=0,1,2,... into given function to find few points then graph those points and join them by a curved line.
That will give the final graph as attached below:
for x=0,
f(x)=x^2-4x-5
f(0)=0^2-4(0)-5
f(0)=0-0-5
f(0)=-5
Hence first point is (0,-5)
Similarly we can find more points.
A=l*w
161=14w
161/14=w
11.5cm is the width
