Identify the form of the equation and two characteristics(example: slope, y--intercept,or point) of the function's graph.
1. y = –7x + 2
2. y + 2 = 2/3(x – 5)
Answer:
1) graphical linear equation form (slope = -7, y-intercept = 2)
2) Standard linear form (slope = 2/3, y-intercept = -4/3)
Step-by-step explanation:
1) A graphical equation is always in the form of y = mx + c where y is the subject.
slope is the value before x which is -7
Y-intercept is where a line meets y axis so the value of x is 0. Y-intercept is 2.
y = -7x + 2
y= -7 (0) + 2 = 2
2) A standard form is where y is not the subject.
Step 1: Convert it into graphical equation form y = mx + c to identify the slope and y-intercept.
y + 2 = 2/3(x – 5)
y + 2 = 2/3x - 10/3
y = 2/3x - 10/3 -2
y= 2/3x - 4/3
slope is the value before x which is 2/3
Y-intercept is where a line meets y axis so the value of x is 0. Y-intercept is -4/3.
y= 2/3x - 4/3
y = 2/3 (0) - 4/3
y = -4/3

These percentiles on small data sets are confusing. We have 8 data points. So the median is the average of the 4th and 5th.
The upper quartile, 75th percentile, is between the 6th and 7th data point of the 8. I calculated its index as (8-1)*.75=6.25. One definition of upper quartile has us just pick the next one up, 36 here. Another definition has us interpolate. Since 6.25 = (3/4) 6 + (1/4) 7 we take (3/4) 33 + (1/4) 36 = 33.75 as a 75th percentile. It's hard for me to choose without knowing what you were taught.
Triangle ABC is translated using the rule (x, y) ? (x + 1, y ? 4) to create triangle A?B?C?. If a line segment is drawn from point A to point A? and from point B to point B?, which statement would best describe the line segments drawn?
Answer:
The line segments AA' and BB' are parallel and congruent
Step-by-step explanation:
we know that
When the transformation is a translation, the figure does not change its shape or dimensions,
so
AA'=BB'=CC'
therefore
The line segments AA' and BB' are parallel and congruent
Translation involves moving a function away from its original position.
The statement that describes the line segments is:
Both lines would be parallel and congruent
The translation is given as:
[tex]\mathbf{(x,y) \to (x + 1, y - 4)}[/tex]
Translation is a rigid transformation.
This means that, the image and the pre-image would have the same measure.
So, when a line is drawn from A to A' and B to B'
The lines would be parallelThe lines would be congruentAssume the coordinates of A and B are:
[tex]\mathbf{A = (2,3) }[/tex]
[tex]\mathbf{B = (-4,6) }[/tex]
Apply transformation
[tex]\mathbf{A' = (2 + 1, 3 - 4) = (3,-1)}[/tex]
[tex]\mathbf{'B = (-4 + 1, 6 - 4) = (-3,2)}[/tex]
The distance of lines AA' and BB' is calculated using:
[tex]\mathbf{d = \sqrt{(x_2 -x_2)^2 + (y_2 - y_1)^2 }}[/tex]
So, we have:
[tex]\mathbf{AA' = \sqrt{(2 -3)^2 + (3 - -1)^2 = \sqrt{17}}}[/tex]
[tex]\mathbf{BB' = \sqrt{(-4 --3)^2 + (6 -2)^2 = \sqrt{17}}}[/tex]
Notice that:
[tex]\mathbf{BB' = AA' = \sqrt{17}}}[/tex]
Because translation is a rigid transformation, then lines AA' and BB' would also be congruent

Step-by-step explanation:
[tex]3^2*3^3[/tex]
To solve your equation, employ the use of PEMDAS.
According to PEMDAS, exponents come before multiplication, so we can simply the 3 squared and the 3 cubed first.
3 squared is the same as 3 x 3, which is 9.
3 cubed is the same as 3 x 3 x 3, which is 27.
Thus, our new equation is

What computation will give you the seventh number
Answer:
42 + 14
Step-by-step explanation:
By counting the rows and columns, you'll notice the following:
1) The first pattern has 2 columns and increase by 1 column each time you move to the right.
2) The first pattern has 1 row and increase by 1 row each time move to the right.
3) To get to the 7th number, you will have to move to the right 6 times.
Hence,
1) if you start with 2 columns, and move 6 times to the right, each time adding one column you will end up with 2 + 6 = 8 columns
2) if you start with 1 row and move 6 times to the right, each time adding one row, you will end up with 1 + 6 = 7 rows
3) You will end up with a pattern with 8 columns and 7 rows and the number of dots will be 8 x 7 = 56.
If you work out all the answers, yo uwill see that only 42 + 14 gives you 56.

Blake and Ned work for a home remodeling business. They are putting the final touches on a home they renovated. Working alone, Blake can paint one room in 9 hours. Ned can paint the same room in 6 hours. How long will it take them to paint the room if they work together?
Answer: The time taken by both of them if they work together is given by
[tex]3\dfrac{3}{5}\ hours[/tex]
Step-by-step explanation:
Since we have given that
Time taken by Blake to paint one room = 9 hours
Time taken by Ned to paint one room = 6 hours
Work done by Blake = [tex]\dfrac{1}{9}[/tex]
Work done by Ned = [tex]\dfrac{1}{6}[/tex]
Total work done by both of them together is given by
[tex]\dfrac{1}{6}+\dfrac{1}{6}\\\\=\dfrac{3+2}{18}\\\\=\dfrac{5}{18}[/tex]
So, the time taken by both of them if they work together is given by
[tex]\dfrac{18}{5}=3\dfrac{3}{5}\ hours[/tex]
Blake can do the work in 9 and part of work in 1 hour = 1/9
Ned can paint the same room in six hours, as well as do part of work in 1 hour = 1/6
If they do it together = 1/9+1/6=5/118, and they can do 5/18 part of work in hour = 1
So, they can do whole work in hours = 1/5/18=3.6
So if they do it together it will only take 3.6 hours.

The sum the other angles that do not measure 22° is equal to 316°.
[tex]158\°+158\°=316\°[/tex]
Why?To find the sum of the rest of the angles, we need to remember that a rhombus has two adjacent and equal angles, and also it has two opposite and equal angles.
So, we are given that the rhombus has an angle of 22°, and to calculate the other angles, let be the given angle an adjacent angle, so:
[tex]360\°=2*AdjacentAngles+2*OppositeAngles\\\\360\°=2*22\°+2*OppositeAngles\\\\2OppositeAngles=360\°-2*22\°=316\°\\\\OppositeAngles=\frac{316\° }{2}=158\°[/tex]
Hence, we have that the sum of its other angles that do not measure 22° is equal to 316°.

Vectors can be multiplied by scalars, where each component of the vector is multiplied by the scalar. In the student's question, direct multiplication isn't possible due to different number of components in both vectors. However, we can partially apply the concept to illustrate vector and scalar multiplication.
Explanation:The question being asked here is about multiplying vectors within the subject of Mathematics. It's important to note that vectors can be multiplied by scalars, and each component of the vector is multiplied by the scalar. In this question, it seems there might be a typo because the two vectors have a different number of components and cannot be multiplied directly.
However, multiplication of vectors by scalars does not involve reversing signs or changing magnitude based on whether the scalar is negative or positive. If Vector A is multiplied by a scalar c, all components of Vector A are simply multiplied by c.
So, applying this concept to part of the vectors in the question, we would get [0, 4, -3] when [4, 0, -1] is multiplied by the scalar 0 and 1 respectively.

A pizza restaurant charges for each pizza and adds a delivery fee. The cost (c), in dollars, to have any number of pizzas (p) delivered to a home is described by the equation c = 11p + 5.
Each pizza costs $5 and the delivery fee is $11
The cost of 11 pizzas is $16
Each pizza costs $11 and the delivery fee is $5
The cost of 5 pizzas is $11
Answer:
Each pizza costs $11 and the delivery fee is $5
Step-by-step explanation:
We assume you want an interpretation of the equation.
The total cost of an order is the sum of any fixed cost (such as a delivery fee) and the variable cost.
Here, the variable cost is the cost of some number of pizzas. It is proportional to the number of pizzas. In the equation, it is represented by 11p, where p is the number of pizzas. The cost of each pizza must be $11, since the cost of p pizzas is 11p.
The equation's two parts are a fixed cost of $5 and a variable cost of $11 per pizza. The best description is ...
Each pizza costs $11 and the delivery fee is $5
The cost (c) to have any number of pizzas (p) delivered is calculated using the equation c = 11p + 5. This implies that each pizza costs $11 and the delivery fee is $5.
Explanation:The question involves the concept of linear equations in mathematics. In this particular case, the equation is c = 11p + 5. This equation denotes the cost (c) of pizzas delivered where each pizza prices ($11 each) is multiplied by the number of pizzas (p) and then added to the delivery fee ($5). Therefore, the third option, 'Each pizza costs $11 and the delivery fee is $5' is the correct interpretation of the equation.
To find out the cost of any number of pizzas, you would substitute that number in for 'p' in the equation. For instance, the cost of 5 pizzas would be calculated as 5 * $11 + $5 = $60.
