Answer:
216 x^3 - 540 x^2 + 450 x - 125 = (6 x - 5)^3
Step-by-step explanation:
The first one cannot be a perfect cube, since the first term contains x^2 and not x^3.
the second one is not a perfect square (the coefficient of the middle term should be an even number: "-90")
The third expression is the perfect cube as shown.

Answer:
[tex]y=9.75x[/tex]
Step-by-step explanation:
Your y is always the dependent variable, or the value that changes when another value changesSo which one depends on the other, between the 'money for school charity' and 'number of lawns mowed'? the money for charity depends on how lawns are mowed, so this is yNow we have y, and we already know it depends on the number of loans mowed, so number of lawns mowed is xSo an equation in the form [tex]y=mx+b[/tex] is a slope-intercept form where m is the slope and b is just a constant number, in this case b is 0.so we have [tex]y=mx[/tex]Now the slope m is interesting because it is the "amount of change"Let's ask ourselves, when Donny mows one lawn he gets, 9.75 dollars, and when he mows 2 lawns he gets 19.5 dollarsThe amount change here is 9.75, so that's our slope m is 9.75so the equation is [tex]y=9.75x[/tex]Find the small positive integer solution that solves the equation. if there is no solution, type NONE.
(8x)(mod 13)≡4
x=?
9514 1404 393
Answer:
x = 7
Step-by-step explanation:
The equation can be rewritten to ...
8x = 13n +4 . . . . for some integers x and n
x = (13n +4)/8
For x to be an integer, 13n must be an odd multiple of 4. Since 13 is an odd number, n=4 will do.
x = (13·4 +4)/8 = 56/8
x = 7
__
The graph shows a "trial and error" method of solution. Only values of x less than 13 need to be examined.

Find the slope of the line contains P1 and P2
Interpret this slope
P1=(-1,3 and p2 =(5,-1)
Answer:
[tex]m = -\frac{2}{3}[/tex]
Step-by-step explanation:
Given
[tex]P_1 = (-1,3)[/tex]
[tex]P_2 = (5,-1)[/tex]
Required
Determine and interpret slope
Slope is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (-1,3)[/tex]
[tex](x_2,y_2) = (5,-1)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex] becomes
[tex]m = \frac{-1 - 3}{5 - (-1)}[/tex]
[tex]m = \frac{-1 - 3}{5 +1}[/tex]
[tex]m = \frac{-4}{6}[/tex]
[tex]m = -\frac{2}{3}[/tex]
The above slope is negative and it implies that x increases when y decreases and vice versa.

f(x)=−10x2−x and g(x)=−2x2−x, find (f−g)(x) and (f−g)(−2)
Answer:
(f - g)(x) = -8x²
(f - g)(2) = -32
General Formulas and Concepts:
Algebra I
Combining like termsStep-by-step explanation:
Step 1: Define
f(x) = -10x² - x
g(x0 = -2x² - x
(f - g)(x) is f(x) - g(x)
(f - g)(2) is f(2) - g(2)
Step 2: Find (f - g)(x)
Substitute: (f - g)(x) = -10x² - x - (-2x² - x)Distribute -1: (f - g)(x) = -10x² - x + 2x² + xCombine like terms: (f - g)(x) = -8x²Step 3: Evaluate
Substitute: (f - g)(2) = -8(-2)²Evaluate: (f - g)(2) = -8(4)Multiply: (f - g)(2) = -32And we have our answers!
Over which interval of the domain is function h decreasing?
The interval of the domain of the considered function for which the function is decreasing is none. The function is strictly increasing: Option D: The function is increasing only.
When do we say that a function is decreasing?Suppose that the function is y = f(x)
If for an interval I, when x increases meanwhile staying in the interval I, the function's output decreases (or can stay same), then we say that the function is decreasing in the interval I.
This interval I was of values that x can take for this function, which is the domain of the considered function, so we say:
y = f(x) is decreasing function in an interval I if:
[tex]f(x+\delta) \leq f(x) \: \forall x \in I : x+\delta \in I[/tex]
If we have:
[tex]f(x+\delta) < f(x) \: \forall x \in I : x+\delta \in I[/tex], then the function is called strictly decreasing in the interval I.
Similarly, there increasing( [tex]f(x+\delta) \geq f(x) \: \forall x \in I : x+\delta \in I[/tex] ) and strictly increasing([tex]f(x+\delta) > f(x) \: \forall x \in I : x+\delta \in I[/tex] ) functions.
For this case, the function is:
[tex]h(x) = \left \{ {{2^x, x < 1} \atop \: \atop {\sqrt{x+3}, x \geq 1}} \right.[/tex]
The function is differentiable in either side of 1.
Sign of rate of function at a point tells whether its increasing or decreasing.
For x < 1:[tex]h'(x)= 2^x ln(2)[/tex]
We know that:
[tex]2^x > 0 \: \rm \forlall x \in \mathbb R[/tex]
And [tex]ln(2) \approx 0.69 > 0[/tex]
Thus, [tex]h'(x)= 2^x ln(2) > 0 \: \forall x \in \mathbb R[/tex]
So, rate is positive, the function is strictly increasing for this case.
For x > 1:[tex]h'(x) = \dfrac{1}{2\sqrt{(x+3)}}[/tex]
For all x > 1, [tex]\sqrt{x+3} > 0[/tex], and so as h'(x)
So rate is positive and therefore strictly increasing for this case too.
For x = 1:[tex]h(1+\delta) - h(1)= \sqrt{1+\delta + 3} - \sqrt{1+3} = \sqrt{4+\delta} - \sqrt{4} > 0 \forall \delta > 0[/tex]
So rate of the considered function is positive,so function is strictly increasing all over the domain.
Thus, the interval of the domain of the considered function for which the function is decreasing is none. The function is strictly increasing: Option D: The function is increasing only.

1. If a student's course grade was a B, what is the probability that a randomly selected student did at least 30 minutes of homework at night?
2. Are the events "did at least 30 minutes of homework l" and "course grade is a B" independent? Explain your answer.
9514 1404 393
Answer:
0.70yesStep-by-step explanation:
1. P(≥30 | B) = P(≥30 & B)/P(B)
P(≥30 | B) = 0.21/0.30 = 0.70
The probability that a B student did at least 30 minutes of homework is 0.70.
__
2. The probability that any student did at least 30 minutes of homework is shown in the column a the right end of the table: 0.70. This is the same as the probability that a B student did at least 30 minutes of homework. That is ...
P(≥30 | B) = P(≥30)
Hence, the events "at least 30 minutes of homework" and "B student" are independent.
Given △XPS≅△DNF, find the values of x and y.
Answer:
x = 3
y = 15
Step-by-step explanation:
If △XPS ≅△DNF, their corresponding sides would be congruent. This implies that:
XP ≅ DN
PS ≅ NF
XS ≅ DF
Given that:
XP = 4y - 3
DN = 57
NF = 51
XS = 17x + 3
DF = 54
Therefore:
XP = DN
4y - 3 = 57 (Substitution)
Add 3 to both sides
4y = 57 + 3
4y = 60
Divide both sides by 4
y = 60/4
y = 15
Also,
XS = DF
17x + 3 = 54 (substitution)
Subtract 3 from each side
17x = 54 - 3
17x = 51
Divide both sides by 17
x = 51/17
x = 3

Marshall can buy 5 T-shirts for $55.
If each shirt costs the same amount, what is the cost of 3 T-shirts?
The cost of 3 T-shirts is $
.
Answer:
$33
Step-by-step explanation:
55 divided by 5 is 11, so each shirt costs $11. So that means 3 shirts would be $33.
Answer:
$33
Step-by-step explanation:
$33 because 55 dollars divided by 5 shirts is 11 dollars so multiply 11 by 3 and the answer is $33
The exchange rate for 1 dollar is 1.3021 euros
Answer:
889.021796 (or simplifyed, 889.02)
Step-by-step explanation:
1 USD = 1.3021 EU
so what we do here is multiply 1.3021 and 682.76
1.3021 x 682.76 = 889.021796

B:He started on page 30 and read 8 pages each day.
C:He started on page 20 and read 12 pages each day.
D:He started on page 20 and read 10 pages each day.
Answer:
[tex]y = 25 + 6x[/tex]
Step-by-step explanation:
The given options are not in anyway related to the question. So, I will do away with them.
Given
[tex]Set-up\ Fee = \$25[/tex]
[tex]Per\ Shirt = \$6[/tex]

Determine the linear relationship
Let
y represents the total cost
x represents the number of shirts
The relationship between x and y is:
[tex]y = Setup\ Fee + Amount\ Per\ Shirt * x[/tex]
This gives:
[tex]y = 25 + 6* x[/tex]
[tex]y = 25 + 6x[/tex]

Eliza volunteers at a nearby aquarium where she tracks the migratory patterns of humpback whales from their feeding grounds to their breeding grounds. She recorded the distance traveled by the whales each day for a 7-day period at the start of their migration. Based on Eliza's data, about how long will it take the humpback whales to travel the 3,100 miles to their breeding grounds?
Answer:
Step-by-step explanation:
This is a very confusing, or otherwise incomplete question. The data Eliza recorded from her study at the aquarium is not given, and thus we wouldn't be able to peg a number as the time it took to travel 3100 miles by the whales.
There are lots of date missing, the total number of whales the distance each whale traveled and even, how long each traveled. These missing has essentially rendered the question unsolvable
