If using the method of completing the square to solve the quadratic equation
X2 – 9x + 38 = 0, which number would have to be added to "complete the
square"?
Answer:
Step 1 Divide all terms by a (the coefficient of x2).
Step 2 Move the number term (c/a) to the right side of the equation.
Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

Answer:
give them all a common denominator
1/3= 2/6
5/6= 5/6
1/2= 3/6
1/6= 1/6
and then use the "new" fraction to order the other ones. but be sure to use the original values, not the ones you made using the GCF. so the answer would be:
1/6, 1/3, 1/2, 5/6
when solving an equation, which is the best first step to begin to simplify the equation? -2(x+3)=-10
Answer: Following the rules of PEMDAS, you want to divide both sides of the equation by -2. This would change your equation to x+3=5. Then you move your constant to the right-hand side and change its sign. Your equation is now x=5-3. subtract 5-3 and your answer is x=2.

Which pair of vectors is orthogonal?
u = ⟨–3, 2⟩ and v = ⟨–2, 1⟩
u = ⟨1, 5⟩ and v = ⟨–5, 1⟩
u = ⟨2, 1⟩ and v = ⟨–4, 3⟩
u = ⟨2, 3⟩ and v = ⟨3, 1⟩
Answer:
B: u = (1,5) and v = (-5,1)
Step-by-step explanation:
edge 2021
The pair of vectors which are orthogonal to each other will be u = ⟨1, 5⟩ and v = ⟨–5, 1⟩. Then the correct option is B.
What is a vector?The quantity which has magnitude, direction and follows the law of vector addition is called a vector.
For the orthogonal vector, the dot product of two vectors will be zero.
Check first option, we have
u·v = ⟨–3, 2⟩·⟨–2, 1⟩
u·v = 6 + 2 = 8 (incorrect)
Check second option, we have
u·v = ⟨1, 5⟩·⟨–5, 1⟩
u·v = –5 + 5 = 0 (correct)
Check third option, we have
u·v = ⟨2, 1⟩·⟨–4, 3⟩
u·v = –8 + 3 = –5 (incorrect)
Check fourth option, we have
u·v = ⟨2, 3⟩·⟨3, 1⟩
u·v = 6 + 3 = 9 (incorrect)
Then the correct option is B.

A 6 ounce serving of grapefruit juice contains 171 grams of water. How many grams of water are in 20 ounces of grapefruit juice?
Please help me with this question. I have 2 minutes left to answer it.
Answer:
570 grams of water
Step-by-step explanation:
171 divided by 6 = 28.5
28.5 grams are in 1 ounce
so Multiply 28.5 by 20 to get the new amout which is 570
The amount of water present in 20 ounces of grapefruit juice will be 570 grams.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
A 6-ounce serving of grapefruit juice contains 171 grams of water.
The ratio of the amount of grapefruit and water present will remain constant.
Let 'x' be the amount of water present. Then the equation is given as,
x / 20 = 171 / 6
x = 20 · 171 / 6
x = 570 grams
The amount of water present in 20 ounces of grapefruit juice will be 570 grams.

Step-by-step explanation:
Possible factors that could produce 3x² + 6x +3 are (x + 1)(3x + 3)
the solution for values of x: x+1=0, x= -1 3x+3=0, 3x= -3 . x= -1 . Same.
Possible factors that could produce 3x² - 6x +3 are (x - 1)(3x - 3)
the solution for values of x: x-1=0, x= 1 3x-3=0, 3x= 3 . x= 1 . Same.
From the attached graph of the possible equations, you can see that 9 and -9 won't produce ONE real solution. They each have "zeros" at two points on the x-axis. That is two solutions that would make x = 0.
The equations with -6 and +6 each touch the x-axis at only one point each.

You spend $63 on books and movies. You pay $12 per book and $15 per movie. You buy 3 more books than movies. How many of each item do you buy?
Answer:12B - 12M = 36

−2 1/6 divided by 1 1/4
100 points
Answer:
-1 11/15Step-by-step explanation:
−2 1/6 divided by 1 1/4:
-2 1/6 ÷ 1 1/4 = - 13/6 ÷ 5/4 = - 13/6 × 4/5 = - 26/15 =-1 11/151) to divide that mixed number we'll need to turn it into an improper fraction:
[tex] - 2\frac{1}{6} = - ( \frac{6 \times 2 + 1}{6} ) = - \frac{13}{6} \\ 1 \frac{1}{4} = \frac{4 \times 1 + 1}{4} = \frac{5}{4} [/tex]
2) now let's divide it, reciprocating 1 1/4 and multiplying both fractions one by another:
[tex] - \frac{13}{6} \times \frac{4}{5} = - \frac{52}{30} = - \frac{26}{15} [/tex]
3) Hence the answer is -26/15
In a small private liberal arts college, 40 percent of the students receive financial aid, and 30 percent of the students that receive financial aid also are first generation college students. In addition, 25 percent of the students in the college own a hybrid car. What is the probability that a randomly selected student receives financial aid and is first generation college student
Answer:
P(A∩B) = 0.12
Step-by-step explanation:
Given:
Students receive financial aid P(A) = 40% = 0.4
Students receive financial aid and first generation P(B/A) = 30% = 0.3
Find:
Probability [Selected student receives financial aid and is first generation college student] P(A∩B)
Computation:
P(A∩B) = P(A) x P(B/A)
P(A∩B) = 0.4 x 0.3
P(A∩B) = 0.12
