A line includes the points (-1,-4) and
(-3, 8). What is its equation in slope-
intercept form?
Answer:y=-6x-10
Step-by-step explanation:
The slope intercept form is y=mx+b
m=slope
b=y intercept
we can find the slope using the slope formula y2-y1/x2-x1
8-(-4)/-3-(-1)
12/-2
m=-6
substitute in the slope, and one of the points so solve for b
y=-6x+b
-4=-6(-1)+b
-4=6+b
b=-10
y=-6x-10
Answer:
y = -6x - 10
Step-by-step explanation:
(-1, -4), (-3, 8)
(x₁, y₁) (x₂, y₂)
y₂ - y₁ 8 - (-4) 8 + 4 12
m = ------------ = -------------- = ------------ = ------- = -6
x₂ - x₁ -3 - (-1) -3 + 1 -2
y - y₁ = m(x - x₁)
y - (-4) = -6(x - (-1))
y + 4 = -6(x + 1)
y + 4 = -6x - 6

What is balance sheet?A balance sheet is a financial statement that lists the assets and liabilities of a corporation at a certain point in time. It is one of the three primary financial statements—the other two being the income statement and cash flow statement—that are used to assess a company's performance.
The weekly income is of $21,000, while a month is composed by four weeks, hence the monthly income is of:
=4 x $21,000
= $84,000.
Then the percentages of each expenses are applied to find the values, for example, 42% of that is for employee wages, hence:
= 0.42 x 84,000
= $ 35, 280
From the details we get Employee Wages 42% of $35,280.00
Hence, the balance will be of zero and option A is correct.

Temperatures in °F can be converted in °C using the formula
C=5(F-32)/9
Make F the subject of the formula
Give your answer in the form aC+b/c where a,b and c are all positive integers
Answer:
Step-by-step explanation:
To make F the subject of the formula, you need to solve for F in the equation C = 5(F-32)/9.
You can do this by first multiplying both sides of the equation by 9 to get rid of the fraction:
C * 9 = 5(F-32)
Then, you can distribute the 5 on the right side of the equation:
C * 9 = 5F - 160
Then, you can add 160 to both sides of the equation to isolate the F term:
C * 9 + 160 = 5F
Finally, you can divide both sides of the equation by 5 to solve for F:
F = (C * 9 + 160)/5
This gives you the final form of the equation:
F = (9C + 160)/5
In this form, F is the subject of the formula. a = 9, b = 160, and c = 5 are all positive integers.
Answer:
[tex]F=\dfrac{9C+160}{5}[/tex]
Step-by-step explanation:
Given equation:
[tex]C=\dfrac{5(F-32)}{9}[/tex]
Multiply both sides by 9:
[tex]\implies 9C=5(F-32)[/tex]
Divide both sides by 5:
[tex]\implies \dfrac{9C}{5}=F-32[/tex]
Add 32 to both sides:
[tex]\implies \dfrac{9C}{5}+32=F[/tex]
[tex]\implies F=\dfrac{9C}{5}+32[/tex]
Rewrite 32 as a fraction with denominator 5:
[tex]\implies F=\dfrac{9C}{5}+\dfrac{32 \cdot 5}{5}[/tex]
[tex]\implies F=\dfrac{9C}{5}+\dfrac{160}{5}[/tex]

Rose chin deposited $900 in a new savings account. The amount for $1.00 compounded daily the account earns after 12 years at 5.25% interest is 1.878. Calculate the compound interest earned after 12 years.
The answer to this Question based on Compound Interest is 1690.2$
What is Compound Interest?
Compound interest is a type of interest that is calculated not only on the initial principal but also on the accumulated interest of previous periods. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal plus previously accumulated interest. It is the concept of earning interest on interest, which causes the total balance to grow at a faster rate than simple interest. Compound interest is often referred to as the eighth wonder of the world, as it is a powerful financial concept that can yield impressive results over a long period.
Initial money deposited = 900$
1$ turns into 1.878$ after 12 years of Compound Interest
hence by basic manipulation we can do like
900$ turns into 900 multiplied by 1.878 which comes out to b 1690$
Hence after 12 years final amount will be 1690$

Answer: The ratio of red marbles to blue marbles is 3:6. This can be written as a fraction as 3/6, which simplifies to 1/2.
Step-by-step explanation:
To find the ratio of two quantities, you can divide the number of one type of item by the number of another type of item. In this case, the ratio of red marbles to blue marbles is 3 marbles / 6 marbles, which simplifies to 1/2.
It's important to note that a ratio is not the same thing as a percentage or a fraction. A ratio is a comparison of two quantities, while a percentage is a measure of a quantity relative to the total amount and a fraction is a division of one number by another.

-2/3, is the slope of the line that passes.
What is slope?A line's steepness and direction are measured by the line's slope.
Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
Any two different points on a line can be used to calculate the slope of any line.
A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.
Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-
P1 = (x1, y1) and P2 = (x2, y2)

why does the normal distribution have an importance in statistics of wether or not iut appears in nature
The normal distribution have an importance in statistics of whether or not out appears in nature, because it fits several natural phenomena.
For exa. measurement error, heights, IQ scores, and physical activity measures all follow the normal distribution.
In this question we need to describe why does the normal distribution have an importance in statistics of whether or not out appears in nature.
We know that if we plot the probability distribution and it forms a bell-shaped curve. If the mean, mode, and median of the sample are equal then the variable has normal distribution.
A normal distribution is dependent on two parameters of the data set: mean and the standard deviation of the sample.
This characteristic of the normal distribution makes it extremely simple.
Also, the normal distribution is important because of the Central limit theorem.
It makes math easy - like calculating moments, correlations between variables, and other calculations that are domain specific.
So, the normal distribution have an importance in statistics of whether or not out appears in nature.

The surface area of the triangular prism is 924 cm².
What is the triangular prism?
When a prism has three rectangular sides and two triangular bases, the prism is said to be triangular. A pentahedron, that is.
Volume is calculated using the formula volume = 0.5 * b * h * length, where b is the triangle's base length, h is its height, and length is the prism length.
Area is defined as length * (a + b + c) + (2 * base area), where a, b, and c are the triangle's sides and base area is the triangle's base area.
The surface area is equal to the area of the two triangles + area of the three rectangles.
Area of two triangles:
12 × (9+5) × 1/2
= 84
84(2) = 168
Area of the three rectangles:

A relation between a domain and range is called a function when each value in the domain only has one value in the range.
Here,
function f : {4, 6, 8} → {2, 3} is defined as {(4, 2), (6, 2), (8, 2)},
domain={4,6,8}
range={2}
The domain of function f : {4, 6, 8} → {2, 3} is defined as {(4, 2), (6, 2), (8, 2)} will be {4,6,8} and range will be {2}.
