What is an equation of the line that passes through the points (2, 2) and
(1, -2)
Answer: y = 4x + -6
Step-by-step explanation:
Match the correct slope-internet form of an equation with the standard form of the same equation.
Given:
-x+y=2
x-y=2
x+y=-2
-x-y=-2
To match the correct slope-intercept form of an equation, we follow the process as shown below:
Standard Form: Ax+By=C
Conversion: y= -A/Bx+C/B
So,
For -x+y=2:
A=-1
B=1
C=2
Hence,
[tex]\begin{gathered} y=-\frac{A}{B}x+\frac{C}{B} \\ y=-\frac{-1}{1}x+\frac{2}{1} \\ Simplify \\ y=x+2 \end{gathered}[/tex]For x-y=2,
A=1
B=-1
C=2
So,
[tex]\begin{gathered} y=-\frac{A}{B}x+\frac{C}{B} \\ =-\frac{1}{-1}x+\frac{2}{-1} \\ Simplify \\ y=x-2 \end{gathered}[/tex]For x+y=-2,
A=1
B=1
C=-2
So,
[tex]\begin{gathered} y=-\frac{A}{B}x+\frac{C}{B} \\ y=-\frac{1}{1}x+\frac{-2}{1} \\ y=-x-2 \end{gathered}[/tex]For -x-y=-2,
A=-1
B=-1
C=-2
So,
[tex]\begin{gathered} y=-\frac{A}{B}x+\frac{C}{B} \\ =-\frac{-1}{-1}x+\frac{-2}{-1} \\ Simplify \\ y=-x+2 \end{gathered}[/tex]Therefore, the answers are:
-x+y=2----y=x+2
x-y=2-----y=x-2
x+y=-2----y= -x-2
-x-y=-2----y= -x+2
What is the annual percentage yield (APY) for money invested at an annual rate of(A) 4.09% compounded monthly?(B) 4.1% compounded quarterly?
The annual percentage yield is given by the following formula:
[tex]\text{APY}=(1+\frac{r}{n})^n-1[/tex]Where r is the stated annual interest rate (in decimal form) and n is the number of times compounded.
A) APY for money invested at an annual rate of 4.09% compounded monthly.
Thus, the annual interest rate in decimal form is:
[tex]r=\frac{4.09\%}{100\%}=0.0409[/tex]And as it is compounded monthly then n=12.
Replace these values and solve:
[tex]\begin{gathered} \text{APY}=(1+\frac{0.0409}{12})^{12}-1 \\ \text{APY}=(1+0.0034)^{12}-1 \\ \text{APY}=(1.0034)^{12}-1 \\ \text{APY}=1.0417-1 \\ \text{APY}=0.0417 \end{gathered}[/tex]The APY is 0.0417=4.17%.
B) 4.1% compounded quarterly:
The annual interest rate is:
[tex]r=\frac{4.1\%}{100\%}=0.041[/tex]As it is compounded quarterly then n=4.
Replace and solve:
[tex]\begin{gathered} \text{APY}=(1+\frac{0.041}{4})^4-1 \\ \text{APY}=(1+0.0103)^{12}-1 \\ \text{APY}=(1.0103)^{12}-1 \\ \text{APY}=1.1302-1 \\ \text{APY}=0.1302 \end{gathered}[/tex]The APY is 0.1302=13.02%

We want to know the mistake is doing Andrew when he tries to draw a copy of ∆ABC using the vector v.
We see that the vector v is directed 3 units to the right, and 3 units down.
For translating the triangle ABC with the vector v, we should make the translation with every point of the triangle.
This means that you move the point A 3 units down and 3 units to the right, but Andrew just moved it 2 units down, and 3 units to the left. Also, we have:
0. The point B was moved two units down and four units to the right.
,1. The point C was moved three units down, and three units to the right
Thus, Andrew didn't move correctly the points A and B.

The slope is [tex]\frac{3}{4}[/tex]
What is slope ?
A line's steepness and direction are determined by the slope of the line. Without actually using a compass, determining a line's slope in a coordinate plane can aid in determining whether the line is parallel, perpendicular, or not. Any two clearly separated points on a line can be used to calculate the slope of any line. Calculated using the slope of a line formula, the ratio of "vertical change" to "horizontal change" between two different locations on a line is determined.
here the given two pints are
[tex](x_1,y_1)=(-2,4)\\(x_2,y_2)=(6,10)[/tex]
Now using slope formula,
slope m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
=> slope m = [tex]\frac{10-4}{6+2}[/tex]
=> slope m = [tex]\frac{6}{8}[/tex]
=> slope m = [tex]\frac{3}{4}[/tex]
Therefore the slope is [tex]\frac{3}{4}[/tex].

Determine the value for x in the equation x over 6 and 4 tenths equals 3 and 6 tenths.
Answer:
x = 23.04
Step-by-step explanation:
You want to know the value of x such that x/6.4 = 3.6.
One-step equationWe can solve this equation by multiplying by the inverse of the coefficient of x.
The coefficient of x is 1/6.4, so multiplying by 6.4 will give ...
6.4(x/6.4) = 6.4(3.6)
x = 23.04
The value for x in the equation is 23.04.

It Carlos sits 3 feet from the fulcrum of a see-saw, how far from the fulcrum must his baby-sister who weighs three-times his weight sit?
A. 1 foot
B. 6 feet
C. 3 feet
D. 9 feet
Answer: B: 6 feet
Step-by-step explanation: To solve this problem, we need to use the concept of leverage, which is the force applied to an object at a distance from its pivot point. In this case, Carlos is applying a force of 3 feet from the fulcrum, while his baby sister is applying a force 3 times as large, at a distance from the fulcrum.
To find the distance from the fulcrum that the baby sister must sit, we need to balance the forces applied by Carlos and his sister. This means that the product of the force applied by Carlos and the distance from the fulcrum must be equal to the product of the force applied by his sister and the distance from the fulcrum where she must sit.
We can use this information to write the equation: 3 * 3 = 3 * x
Where x is the distance from the fulcrum where the baby sister must sit. We can solve for x by dividing both sides of the equation by 3 to get: x = 6
Therefore, the baby sister must sit 6 feet from the fulcrum in order to balance the forces applied by Carlos and his sister. The correct answer is B. 6 feet.

What is the equation of the line that passes through the point (-3,-6) and has a slope of 1/3
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
How can I locate a slope?You may determine the slope of the line by determining the rise and the run using two of the line's points. The rise and the run are terms used to describe changes in height between two points. The increase divided by the run is the slope.The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844) and Todhunter's (1888) expressions of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively.Formula m = rise / run = y2 - y1 / x2 - x1m = slope
(x1, y1) = coordinates of first point in the line
(x2, y2) = coordinates of second point in the line

First we can set the equations we already know
[tex]a\text{ +b +c = 153 ft}[/tex]Where a, b and c are the sides of the triangle. Then, I will assign "a" the shortes side. One side is twice the shortest side so:

[tex]c\text{ = a + 17}[/tex]Now we have a system of three equations with three unknown variables, so it will be easy to find the value of all the variables. If we put "b" and "c" in the first equation we have:

Yesterday jack drove 38 1/2 miles. He used 1 1/4 gallons of gasoline. What is the unit rate for mile per gallon
Answer:
the unit rate for miles per gallons is 32.4 miles per gallon
Step-by-step explanation:
From the information we have, Jack drove 401/2 miles and used a total of 1 1/4 gallons of gasoline.
We need to find out how many miles he travelled per each gallon.
40 1/2 miles can be written as 40.5 miles
1 1/4 gallons can be written as 1.25 gallons.
So now we form an equation.
40.5 = 1.25
x = 1
Where x is the number of miles per gallon
We cross multiply the equation
40.5 * 1 = 1.25 * x
40.5 = 1.25x
40.5 / 1.25 = x
32.4 = x
x = 32 .4

Find the radian measure of θ if θ is a central angle in a circle of radius r=14in and θ cuts off an arc length s=7π in
The formula for determining the length of an arc is experessed as
arc length = θ x r
where
θ is the central angle
r is the radius of the circle
From the information given,
arc length = 7π in
r = 14 in
By substituting these values into the formula,
7π in = θ x 14 in
We would divide both sides of the equation by 14 in. We have
7π in/14 in = θ x 14 in/14 in
θ = π/2
