Here's how you solve this problem:

1) Multiply the first equation by 2 (result:2x+2y=8).

2) Add both equations together (result:2x+x+2y-2y=8-5)

3) Simplify (result:3x=3)

The answer is 3x=3.

This could be simplified more, however, to equal x=1, since both sides are divisible by 3.

p.s. Have a good day!

How much will it cost to borrow $2,500 for a year at a simple interest rate at 14% please explain

Mariana [72]

Principle (P) = $ 2,500

Rate (R) = 14%

Time (T) = 1 year

Simple Interest (SI) = $\frac{PRT}{100}$

SI = $\frac{2500 * 14 * 1}{100} = \frac{25 *14}{1} = 350$

Hence, the answer is $350.

Sharon kicks a ball from the ground into the air with an upward velocity of 64 feet per second. The function h = -16t2 + 64t mod

iren2701 [21]

When the ball reaches the ground is equal to one of the zeros, or x-intercepts. In order to find the zeros of a function, you need to factor the equation.
y=16x^2+64x
y=-16x(x-4)
The zeros are x=0 and x=4
Therefore the answer is D, after 4 seconds.
Hope this helps!
