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}

IVedle Question Help Miranda's financial aid stipulates that her tuition not exceed $1500. If her college charges a $45 registra
forsale [732]

Answer:

Therefore, Miranda can register for at most 3 courses.

Explanation:

If x is the number of courses in which Miranda register, the total cost for her tuition will be:

45 + 450x

Because there is a fixed cost of $45 and a cost per course of $450.

Then, this cost should be less than or equal to $1500, so we can write the following inequality:

45 + 450x ≤ 1500

Now, we can solve the inequality for x. Subtract 45 from both sides:

45 + 450x - 45 ≤ 1500 - 45

450x ≤ 1455

Divide both sides by 450:

450x/450 ≤ 1455/450

x ≤ 3.23

Therefore, Miranda can register for at most 3 courses.

Question 2(Multiple Choice Worth 5 points)
Mamont248 [21]

Answer:

If you mean:

x² = 10

√x² = √10

x = √10

if you meant:

2x = 10

2x/2 = 10/2

x = 10/2

x = 5

hope this helps

If you mean x^2 then there would be no answer after all, 3^2= 9 and 4^2= 16 so

If you mean 2x then the answer would be 5
