Answer:
y = 4
Step-by-step explanation:
for any fraction a/b, the decimal format of it is just a ÷ b.
A)
is the number rational?
well, a rational number is one we can write as a ration or fraction, well clearly is a fraction so it is rational.
B)
can it be written as a repeating/recurring decimal? well, 9/20 is 0.45, so -9/20 is -0.45, no repeating decimal like 0.454545......... , just a plain vanilla -0.45, so nope.
C)
is it less than -0.4?
well, let's recall that for the negative side on the number line, the closer to 0, the larger the number, so then -1,000,000 is much smaller than -1, because -1 is closer to 0.
who is closer -0.4 or -0.45?
|--------------------- -0.45 -------- -0.40 ------------------- 0 --------------- 1 -------------------|
so, -0.45 is farther from 0, and therefore is smaller than -0.4, so yes.
The break even point is when profit is equal to zero, or in this case when p(x)=0
4x^2-28x+40=0
4(x^2-7x+10)=0
4(x^2-2x-5x+10)=0
4(x(x-2)-5(x-2))=0
4(x-5)(x-2)=0
So the break even points are when x=2 and 5, which is when 2000 and 5000 units are sold.
Answer:
x=5/16
Step-by-step explanation:
Let's solve your equation step-by-step.
4x(−4)=−2−(−3)−6
Step 1: Simplify both sides of the equation.
4x(−4)=−2−(−3)−6
−16x=−2+3+−6
−16x=(−2+3+−6)(Combine Like Terms)
−16x=−5
−16x=−5
Step 2: Divide both sides by -16.
−16x
−16
=−5/−16
x=5/16
can I be the brainiest please!!
