Tell whether point (0,-12) is an x - intercept Or a Y intercept
hjlf

The given point is (0,-12).

It is required to tell whether the point is an x-intercept or a y-intercept.

Recall that the first coordinate of a coordinate point represents the x-coordinate, while the second coordinate represents the y-coordinate.

The x-intercept is the point where the y-coordinate is zero.

The y-intercept is the point where the x-coordinate is zero.

Notice that the given point has an x-coordinate of zero; this means that the given point is a y-intercept.

The point is a y-intercept.

System of equations:
x + y = 23
x - y = 7           

Add them together
2x = 30
x = 15

Now plug 15 into one of the equations:
15 + y = 23
y = 8

your two numbers are 15 and 8

PLEASE HELP ME <br>Find m^AB.
N76 [4]

Answer: 68 degrees

To get this answer, you multiply 34 by 2 to get 34*2 = 68. I'm using the inscribed angle theorem. This says that the arc measure is two times that of the inscribed angle, where the inscribed angle cuts off the arc.

$25,000 is invested for 5 years with an APR of 3% and daily compounding.
Effectus [21]

Answer:

$29,045.69

Step-by-step explanation:

The total amount accrued, principal plus interest, with compound interest on a principal of $25,000.00 at a rate of 3% per year compounded 365 times per year over 5 years is $29,045.69.

A = P(1 + r/n)nt

A = 25,000.00(1 + 0.03/365)(365)(5)

A = 25,000.00(1 + 8.2192E-5)(1825)

A = $29,045.69
