What are the x-intercepts of the graph of the equation y = x² + 4x -5 ?
-5 and 1
5 and 1
5 and -1
-5 and 0

-5 and 1

Step-by-step explanation:

x-intercept means where a certain equation touches the x-axis. At this point the value of y will be 0.

So, put y = 0 in y = x² + 4x -5

0 = x² + 5x - x - 5

0 = x(x + 5) - 1(x + 5)

0 = (x - 1) (x + 5)

Either,

x - 1 = 0

x = 1

Or,

x + 5 = 0

x = -5

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
