Answer:
To use the elimination method one coefficient of either x or y must be the same number with opposite signs, so the ordered pair is (-10, -8)
Step-by-step explanation:
2(-x+y=2) Make one of the coefficients equal, with opposite signs.
2x-3y=4 Combine equations.
-y=8 Solve, y=-8
Then find x, -x-8=2
-x=10, so x= -10
(-10, -8) is your answer.
Answer:
The minimum value of a function is the lowest point of a vertex. If your quadratic equation has a positive a term, it will also have a minimum value. ... If you have the equation in the form of y = ax^2 + bx + c, then you can find the minimum value using the equation min = c - b^2/4a.
Answer:
The answer is D
Step-by-step explanation:
To find the answer use multiplication. 87% as a decimal equals 0.87 (87 divided by 100). Then multiply 0.87 by 900. Your answer should be $783.
Answer:
Step-by-step explanation:
if 12 + 18 = 30 and A is the sum of the previous...." the sum " is the result of addition.....means A = 30
so A + 19 = 30 + 19 = 49 <===
