Answer:
3k + 9
Step-by-step explanation:
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.
-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
Two students are both working on the same problem: A box of laundry soap has 25% more soap in its
new box. The new box holds 2 kg. How much soap did the old box hold?
Answer:
The answer would be 1.5kg.
Step-by-step explanation:
2/.25=.50
.50x4=2
100%-25%=75%
75%=1.5kg
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
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.
Meaning, 4 a positive number, will be greater no matter what y is

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
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

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
