Answer:
Yes, Beyonce will get the same solution.
Step-by-step explanation:
The given system is
2x - 3y = - 2
and
4x + y = 24
If she multiplies the first equation by -2 , she gets,
-4x+6y=4
4x + y = 24
Adding the two equations gives
7y=28
This means y=4
When we put y=4 into the bottom equation we get:
4x+4=24
4x=20
x=5
Therefore Beyonce will still get x=5, and y=4 as solution.
Answer:
D) c - 2 = 25 + c + 10√c
Step-by-step explanation:
The given equation is 
Taking square on both sides, we get
Here we used ( a+ b)^2 = a^2 + b^2 + 2ab formula.
c - 2 = 5^2 + (√c)^2 + 2(5)√c
c - 2 = 25 + c +10√c
Answer: D) c - 2 = 25 + c + 10√c
Thank you.
<span>The slope of a line is defined as the rate of change on the vertical axis, divided by the rate of change on the horizontal axis, Δy/Δx. So for a horizontal line, the rate of change on the y axis is zero, this means that it's slope will be 0/Δx and for vertical line, x-axis does not change, which make the denominator 0 Δy/0.</span>
