Answer:

\tt x_1=\cfrac{9-\sqrt{17}}{4}; \ \ x_2=\cfrac{9+\sqrt{17}}{4}

Step-by-step explanation:

\displaystyle\tt 2x^2-9x+8=0\\\\x=\frac{-bб \sqrt{b^2-4ac}}{2a} \\\\x=\frac{9б\sqrt{(-9)^2-4\cdot2\cdot8}}{2\cdot2} \\\\x=\frac{9б\sqrt{81-64}}{4}\\\\x=\frac{9б\sqrt{17}}{4}\\\\x_1=\frac{9- \sqrt{17}}{4}\\\\x_2=\frac{9+ \sqrt{17}}{4}

You buy 24 keyboards for $120 each less 15%. What is your subtotal before taxes?
kotykmax [81]
<span>First, you need to take the 15% off from the $120 so it will make it easier for you to calculate later. Since there is 15% off, your $120 becomes only $102. Since your keyboards only costs $102 each now, you just have to multiply the number of keyboards you wanted to the less price. $102 multiplied by 24 keyboards is equals to $2,448. We don’t have to add taxes because it is stated that we are just looking for SUBTOTAL before taxes. The answer is A. $2,448. <span>

0.75y-1.5y+0.5=5 I need answers to this asap
Mnenie [13.5K]

Answer:

y = -6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.75y−1.5y+0.5=5

0.75y+−1.5y+0.5=5

(0.75y+−1.5y)+(0.5)=5(Combine Like Terms)

−0.75y+0.5=5

−0.75y+0.5=5

Step 2: Subtract 0.5 from both sides.

−0.75y+0.5−0.5=5−0.5

−0.75y=4.5

Step 3: Divide both sides by -0.75.

Hope this helps!
