=>−5x+3y+−3y=5+−3y
=>−5x=−3y+5
Divide both sides by -5\( \sf \: = > \dfrac{ - 5x}{ - 5} = \dfrac{ - 3y + 5}{ - 5} \)
Answerx=3/5 y - 1
\( \frac{3}{5} y - 1\)
Answer:
x = \(\frac{3}{5}\) y - 1
Step-by-step explanation:
3y - 5x = 5 ( subtract 3y from both sides )
- 5x = - 3y + 5 ( divide through by - 5 )
x = \(\frac{3}{5}\) y - 1

Solve for the rate (as a %). Round to the nearest tenth of a percent when necessary. What is the rate if the base is 366 and the portion is 50?
Answers
Answer:
\(\Huge \boxed{\text{13.66$\%$}}\)
Step-by-step explanation:
To find the rate, we need to use the following formula:
\(\LARGE \boxed{ \boxed{\text{Rate = $\frac{\text{Portion}}{\text{Base}}$$\times$100}}}\)
Where "Portion" is the part of the whole and "Base" is the whole.
Now, let's plug in the given values:
\(\large \text{Rate = $\frac{\text{50}}{\text{366}}$$\times$100 = 13.66 (Rounded to the nearest tenth of a percent)}\)
Therefore, the rate is 13.66% (rounded to the nearest tenth of a percent).

For what value of A is the function, (x), continuous at x=0?
Answers
(i) \(\lim_{x \to \frac{\pi^-}{2}}\) h(x) = 3
(ii) \(\lim_{x \to \frac{\pi^+}{2}}\) h(x) = -1
(iii) h(0) = 1/7
The value of λ must be 7, for h(x) to be continuous at x = 0.
The given function is,
h(x) = 1/7, when x = 0
= 1 - 2 cos 2x, when x < π/2
= 1 + 2 cos 2x, when x > π/2
= x cos x/sin λx, when x < 0
Now,
(i) \(\lim_{x \to \frac{\pi^-}{2}}\) h(x) = \(\lim_{x \to \frac{\pi^-}{2}}\) (1 - 2 cos 2x) = 1 - 2 cos π = 1 + 2 = 3
(ii) \(\lim_{x \to \frac{\pi^+}{2}}\) h(x) = \(\lim_{x \to \frac{\pi^+}{2}}\) (1 + 2 cos 2x) = 1 + 2 cos π = 1 - 2 = -1
(iii) h(0) = 1/7
Since the function is continuous at x = 0, so
\(\lim_{x \to 0}\) h(x) = h(0)
\(\lim_{x \to 0}\) x cos x/sin λx = 1/7
\(\lim_{x \to 0}\) cos x.\(\lim_{x \to 0}\) 1/λ(sinλx/λx) = 1/7
1/λ = 1/7
λ = 7
Hence the value of λ must be 7.

Explanation
We can solve each of these by inserting the values for x
y = 25 - 2x
when x = 1
y = 25 - 2x
y = 25 - 2(1)
y = 25 - 2

when x = 2
y = 25 - 2x
y = 25 - 2(2)
y = 25 - 4
y = 21
when x = 5
y = 25 - 2x
y = 25 - 2(5)
y = 25 - 10
y = 15
when x = 6
y = 25 - 2x
y = 25 - 2(6)
y = 25 - 12
y = 13

Answers
Using proportional reasoning, we can predict that there will be 40 red candies in the large bag.
Using proportional reasoning, we can set up and solve the following equation to determine the number of red candies in the large bag:
P = Proportion of red candies in the large bag
R = Red candies in the small bag
R × (33/9) = P
12 × (33/9) = P
P = 40 red candies in the large bag
Therefore, using proportional reasoning, we can predict that there will be 40 red candies in the large bag.

Answers
Answer:
p=4: q = 75q=10: p = 225Step-by-step explanation:
You want to know various values of p and q when p varies inversely as the square of q, and p=36 when q=25.
VariationA formula describing the variation of one variable with another will generally have a constant of variation, which we choose to represent here by the letter k.
Since p varies inversely as the square of q, the formula can be written as ...
\(p=\dfrac{k}{q^2}\)
Multiplying by q² gives us a way to find the value of k from known values of p and q:
k = p·q²
k = 36·25² = 22500 . . . . . . using the given values of p and q
We can also rearrange the formula to give q as a function of p:
q = √(k/p)
Table of valuesWe are interested in q for p=4, and in p for q=10.
q = √(22500/4) = 75
p = 22500/10² = 225
When p=4, q = 75When q=10, p = 225

The darkness of the print is measured quantitatively using an index. If the index is greater than or
equal to 2.0 then the darkness is acceptable. Anything less than 2.0 means the print is too light and

deviation of 0.20.
(a) What percentage of printing jobs will be acceptable? (4)
(b) If the mean cannot be adjusted, but the standard deviation can, what must be the new standard
deviation such that a minimum of 95% of jobs will be acceptable?
Answers
84.13% of the printing jobs will be acceptable.
The new standard deviation required to achieve a minimum of 95% of jobs acceptable is 0.121.
The darkness of the print is measured quantitatively using an index. If the index is greater than or equal to 2.0 then the darkness is acceptable. Anything less than 2.0 means the print is too light and not acceptable. The machines print at an average darkness of 2.2 with a standard deviation of 0.20.
The mean of the darkness of the print is µ = 2.2 and the standard deviation is σ = 0.20.Therefore, the z-score can be calculated as; `z = (x - µ) / σ`.The index required for acceptable prints is 2.0. Thus, the percentage of prints that are acceptable can be calculated as follows;P(X ≥ 2.0) = P((X - µ)/σ ≥ (2.0 - 2.2) / 0.20)P(Z ≥ -1) = 1 - P(Z < -1)Using the standard normal table, P(Z < -1) = 0.1587P(Z ≥ -1) = 1 - 0.1587= 0.8413.
To find the new standard deviation, we can use the z-score formula.z = (x - µ) / σz = (2.0 - 2.2) / σz = -1Therefore, P(X ≥ 2.0) = 0.95P(Z ≥ -1) = 0.95P(Z < -1) = 0.05Using the standard normal table, the z-score value of -1.645 corresponds to a cumulative probability of 0.05. Hence,z = (2.0 - 2.2) / σ = -1.645σ = (2.0 - 2.2) / -1.645= 0.121.

\(6t-4\leq38\)Let's add 4 to both sides of the inequality;
\(\begin{gathered} 6t-4+4\leq38+4 \\ 6t\leq42 \end{gathered}\)Let's divide both sides by 6;
\(\begin{gathered} \frac{6t}{6}\leq\frac{42}{6} \\ t\leq6 \end{gathered}\)So Melissa can rent the boat for up to 7 hours
