Plug in the 2 values for x and y into the equation and see if it works out.
6(-9)-(3)/2=14 => -54-3/2=14 => -55 -1/2 = 14
Which false so the first point is not a solution.
Next point:
6(2)-(-4)/2=14 => 12+2=14 => 14=14
This is clearly true, so the second point is a solution.
Final answer:
Answer choice B, the first is not a solution but the second is.
Hope I helped :)
Answer:
f(x) = - 4x² - 27x + 7
Step-by-step explanation:
f(x) = a*(x-1/4)(x+7) = a(x² + 27/4 x - 7/4)
pass (0,7): 7 = a (-7/4)
a = -4
f(x) = -4*(x² + 27/4 x - 7/4)
f(x) = -4x² - 27x + 7
Answer:
9
Step-by-step explanation:
If the mark up is 75% then the price of a necklace is 56.7
the least they want to profit is 500
so the answer should be at least 9, because the price is over 55, which would be 550 if multiplied by 10
Answer: the answer is 0.125 foot per square foot
Step-by-step explanation:
Answer:
35 degrees
Step-by-step explanation:
Since the 2 horizontal lines are parallel,
angle 4 and angle 2 are alternate interior angles, which are equal
So, angle 2 will be equal to angle 4
Angle 2 = 35 degrees
