What is the largest value of $k$ such that the equation $6x - x^2 = k$ has at least one real solution?
Step-by-step explanation:
6x - x² = k
=> x² - 6x + k = 0,
For there to be at least 1 real solution,
The discriminant b² - 4ac must be at least 0.
We have (-6)² - 4(1)(k) >= 0.
Therefore 36 - 4k >= 0, k <= 9.
Hence the largest value of k is 9.
Answer:
9
Step-by-step explanation:
Rearranging, this is the equation x^2 - 6x = -k. Completing the square, we add 9 to both sides, and x^2 - 6x + 9 = 9 - k. Factoring the left side, we have (x - 3)^2 = 9 - k. In order for this equation to have at least one real solution, the right-hand side must be nonnegative. Thus, we have 9 - k [tex]\geq[/tex] 0 and k [tex]\leq[/tex] 9. Thus, the largest possible value of k is 9.
Solve the following system of equations.
3x + 5y = 5
7x + 5y = 25
i need the value of x and y.
Answer:
x=5 and y=-2
Step-by-step explanation:
3x+5y=5
-(7x+5y=25)
-4x=-20
x=5
plug 5 into one of the equations. 3(5)+5y=5
y= -2
I really need help with this!!! If i get a correct answer ill make another question for more points. best answer gets brainliest
When solving for a quantity in a formula, what are the most important things to consider? What process do you follow in order to be sure that you've correctly solved for some quantity? Explain your reasoning, and give examples to help illustrate your ideas. Don't forget to respond to your peers' posts by reviewing what they've read and attempting to apply their ideas to other examples. Remember, your goal is to demonstrate whether you've made sense of their ideas or not, and to contribute to help everyone improve their explanations.

Answer:
sine 23 = x/21
Multiply both sides by 21
21 x sine 23 = x
Now, use a calculator and find the answer of the 21 times the sine of 23:
x = -17.7706284876

8/13 ln 3 = ln h/12
Answer:
Step-by-step explanation:
I'll assume that you meant
(8/13) ln 3 = ln h/12
Applying rules of logs, we get:
(8/13) ln 3 = ln h - ln 12
= ln h - ln 3 - ln 4 <= because ln b*c = ln b + ln c
Then (8/13) ln 3 + ln 3 = ln h - ln 4, or
(21/13) ln 3 + ln 4 = ln h
3^(21/13) * 4 = h <= because ln b*c = ln b + ln c
Give 5 Examples of Linear Equation in Two Variables
Answer:
Some examples of linear equations in two variables are: 1.2s + 3t = 5, p + 4q = 7, πu + 5v = 9 and 3 = 2 x – 7y. Note that you can put these equations in the form 1.2s + 3t – 5 = 0, p + 4q – 7 = 0, πu + 5v – 9 = 0 and 2 x – 7y – 3 = 0, respectively.

Rewrite in slope-intercept form.
10x + 2y = 8
Enter your answer in the form y=mx+c
Simplify your answer if possible using integers or simplified fractions. Example: y=3/4x-2
10x+2y=8
Answer:
y = -5x + 4
Step-by-step explanation:
Solve for y
10x + 2y = 8
2y = -10x + 8
y = (-10x)/2 + 8/2
y = -5x + 4
Solve for X
Log x - log 3 = log(x-2)
Please please help
Step-by-step explanation:

which expression are equivalent to this exponential expression
Answer:To create an equivalent expression, you simply need to move the base and exponent to the other side of the fraction line and change the exponent to positive: 1/(24)

-3+4b=3(b-2)
what do I have to do slove both sides
Answer:
b=-3
Step-by-step explanation:
distribute 3(b-2) and you get 3b-6.
-3+4b=3b-6
add 3 on both sides.
4b=3b-3
-3b on both sides
b=-3
3x +7y=10 and I’m solving for y and I got multiple awnsers
Answer:
y = ~-0.43x + 1.43
Step-by-step explanation:
You are solving for Y.
3x + 7y = 10
7y = -3x + 10 ^ Subtraction Property of Equality
y = ~-0.43x + 1.43 ^ Division Property of Equality
Solve the inequality
−y/2 ≤ 4
Answer:
4 is greater
Step-by-step explanation:
A negative divided by a positive = a negative.
No matter what y is, it will be a negative number.

Find the value of the variables I’ll mark the brainiest!
Answer:
x=15, y=12, z=20
Step-by-step explanation:
y is the geometric mean of the two segments it divides.
9 · 16 = y^2
y=12
Use the pythagorean theorem to find x and z.
16^2 + 12^2 = z^2
z^2 = 400
z=20
9^2 + 12^2 = x^2
x^2 = 225
x=15
