Haoyu, I'm telling Ms. Mak about your behavior. Expect not to see tomorrow, you were cheating on the math test. I will also contact your parents. Reply to me immidetly if you do not want to get exposed to everyone.
Answer:
No graph so we'll use the quadratic formula
x^2+x-4=0
a = 1
b = 1
c = -4
x = -1 +- sqr root (1^2 - 4 * 1 * -4) / 2
x = (-1 +- sqr root (1 +16) ) / 2
x1 = (-1 + sqr root (17)) / 2
x2 = (-1 - sqr root (17)) / 2

The answer is:
B - x = 5
Hope it helps!
Have a nice day hyung/noona!!~ ￣▽￣❤️
Answer:
B
Step-by-step explanation:
6x - 6/3 = 2x - 2
6x - 2 = 2x - 2
6x - 2 + 2 = 2x - 2 + 2
6x = 2x
6x - 2x = 0
4x = 0
Divide both sides by 4
4x/4 = 0/4
x = 0
The equation has exactly one solution.
Reasons are that it is an algebraic linear equation where the unknown variable, x has highest power as 1.
Also after solving for x, we see that we got only one value or solution for x
Answer:
x = 10
Step-by-step explanation:
To isolate the variable (x) you would first write out x - 3 = 7. Now to make x on its own we have to get rid of the -3 so to do that we would add the reciprocal of -3 (or the opposite) which is +3. x - 3 + 3 = 7 + 3 or x = 10.
