When answering all these questions, you specific points in the equation
Answers
1. We have a point $(-4,-3)$ and a slope of $1/5$. Using point-slope form, we get:
$y - y_1 = m(x - x_1)$
$y - (-3) = \frac{1}{5}(x - (-4))$
Simplifying, we get:
$y + 3 = \frac{1}{5}(x + 4)$
This is the equation in point-slope form.
2. We have a point $(1,3)$ and a slope of $9$. Using point-slope form, we get:
$y - y_1 = m(x - x_1)$
$y - 3 = 9(x - 1)$
This is the equation in point-slope form.
3. We have a point $(-4,-1)$ and a slope of $-10$. Using point-slope form, we get:
$y - y_1 = m(x - x_1)$
$y - (-1) = -10(x - (-4))$
Simplifying, we get:
$y + 1 = -10(x + 4)$
This is the equation in point-slope form.
4. We have a point $(9,3)$ and a slope of $-\frac{1}{6}$. Using point-slope form, we get:
$y - y_1 = m(x - x_1)$
$y - 3 = -\frac{1}{6}(x - 9)$
This is the equation in point-slope form.
5. We have two points $(1,2)$ and $(2,10)$. We can find the slope using the slope formula:
$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{10 - 2}{2 - 1} = 8$
Using point-slope form with the point $(1,2)$ and the slope $8$, we get:
$y - y_1 = m(x - x_1)$
$y - 2 = 8(x - 1)$
This is the equation in point-slope form.

Answers
The percentage of saline solution in brand B is 3%.
Let x be Percentage of saline solution in brand B
We know that the overall volume of saline solution in the combination is 18% of 6 gallons plus x% of (18 - 6) gallons since Danielle blended brands A and B to make a total of 18 gallons of 8% saline solution.
Then the equation is given as,
0.18(6) + 0.01x(18 - 6) = 0.08(18)
Simplifying and solving for x, we get:

Let x be the number of 16 oz jars of peanut butter collected, and y be the number of 28 oz jars of peanut butter collected.
The system of equations that represents the constraints in this situation is:
x + y = 82 (total number of jars collected)
16x + 28y = 1876 (total amount of peanut butter collected in ounces)
b. To solve for the number of 16 oz jars and 28 oz jars of peanut butter donated to the food bank

At a circus, 135 clowns are getting into cars. Blue cars hold 20 clowns and red cars only hold 15. There are a total of 8 cars. How many of each are there?
Answers
b + r = 8 (because there are a total of 8 cars)
20b + 15r = 135 (because the total number of clowns is 135)
We can use the first equation to solve for one of the variables in terms of the other:
b = 8 - r
Then we can substitute this expression for "b" into the second equation and solve for "r":
20(8 - r) + 15r = 135
160 - 20r + 15r = 135
-5r = -25
r = 5
So there are 5 red cars and 3 blue cars (because 8 - 5 = 3).

31. There are two gears that are connected to each other. One gear has 20 teeth and the other gear has 10 teeth. If the bigger gear turns around 5 times, how many times will the smaller gear turn?
Answers
10 times will the smaller gear turn.
What is the ratio?
The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Since the smaller gear has 10 teeth and the bigger gear 20, the smaller gear will turn twice for every rotation of the larger gear (20/10=2).
Therefore, if the larger gear rotates five times, the smaller gear will rotate two times five times, or ten times. The smaller gear will thus rotate 10 times.
So, if the bigger gear turns around 5 times, the smaller gear will turn around 5 x 2 = 10 times.
Therefore, the smaller gear will turn 10 times.

Answers
The preceding polynomial equation has three solutions: z = 0, z = 3/4, and z = -1/5.
First, we can factor out a common factor of z:
z(20z² - 11z - 3) = 0
Now we need to factor the quadratic expression in the parentheses.
We can use the quadratic formula or factor by grouping to do this. Factoring by grouping yields:
z(20z² - 11z - 3) = 0
z(4z - 3)(5z + 1) = 0
Setting each of the factored terms equal to zero, we have:
z = 0, 3/4, -1/5

How to explain the domainIn determining the function's output values, one must consider its collection of feasible results to extract the range. Reviewing f(x)* exhibits a minimum value of 1 due to x^2 being perpetually non-negative, while adding another factor merely preserves positivity.
Concurrently as x skyrockets, so too does the value of f(x)* given that approaching infinity generates infinitely larger powers than any constant coefficient subordinated by it. Consequently, the overall range of f(x)* becomes [1, ∞), enwrapping all feasible solutions equivalent or superior to 1.

We raise the fraction to the power of 4/3.
To evaluate the expression:

we can simplify each term within the parentheses before multiplying them together.
Let's simplify each term step by step:
\left( \frac{16}{9} \right)^{2/3}:
To simplify this term, we raise the fraction to the power of 2/3.
\left( \frac{16}{9} \right)^{2/3} = \left( \left( \frac{2^4}{3^2} \right)^{1/3} \right)^2 = \left( \frac{2^{4 \cdot 1}}{3^{2 \cdot 1}} \right)^2 = \left( \frac{2^4}{3^2} \right)^2 = \left( \frac{16}{9} \right)^2 = \frac{16^2}{9^2} = \frac{256}{81}
\left( \frac{4}{3} \right)^{4/3}:
Similarly, we raise the fraction to the power of 4/3.
\left( \frac{4}{3} \right)^{4/3} = \left( \left( \frac{2^2}{3^1} \right)^{1/3} \right)^4 = \left( \frac{2^{2 \cdot 1}}{3^{1 \cdot 1}} \right)^4 = \left( \frac{2^2}{3^1} \right)^4 = \left( \frac{4}{3} \right)^4 = \frac{4^4}{3^4} = \frac{256}{81}
\left( \frac{9}{16} \right)^{2/3}:
We raise the fraction to the power of 2/3.
\left( \frac{9}{16} \right)^{2/3} = \left( \left( \frac{3^2}{2^4} \right)^{1/3} \right)^2 = \left( \frac{3^{2 \cdot 1}}{2^{4 \cdot 1}} \right)^2 = \left( \frac{3^2}{2^4} \right)^2 = \left( \frac{9}{16} \right)^2 = \frac{9^2}{16^2} = \frac{81}{256}
\left( \frac{3}{4} \right)^{4/3}:
We raise the fraction to the power of 4/3.
\left( \frac{3}{4} \right)^{4/3} = \left( \left( \frac{3^1}{2^2} \right)^{1/3} \right)^4 = \left( \frac{3^{1 \cdot 1}}{2^{2 \cdot 1}} \right)^4 = \left( \frac{3^1}{2^2} \right)^4 = \left( \frac{3}{4} \right)^4 = \frac{3^4}{4^4} = \frac{81}{256
