The equation for line bis y = -2x + 3. Line c is the result of dilating line b by a factor
of 2 with center (0, -2). What is the equation for line c?
Answer:
[tex]y = - 2x + 8[/tex]
Step-by-step explanation:
The given equation is
[tex]y = - 2x + 3[/tex]
This is the equation of line b.
We want to find the equation of line c, after b is dilated by scale factor of 2 with center (0,-2).
Note that line c and b still have the same because they are parallel.
Also the y-intercept of b is 3.
The distance of the y-intercept of line b from the center of dilation is 5.
After a dilation by scale factor of 2, the y-intercept of c will be 2(5) =10 units from the center.
The y-intercept of c will therefore be:
10+-2=8
The equation c is
[tex]y = - 2x + 8[/tex]

Using the three indicated points on the given line and the concept of similar triangles, show and explain why the slope of the line is the same between any two of these three points. Calculate the slope of the line.
Answer:
Slope = 3/2 or 1.5
Step-by-step explanation:
(0,1) (2,4) (6,10)
Slopes:
(4-1)/(2-0) = 3/2
(10-4)/(6-2) = 6/4 = 3/2
(10-1)/(6-0) = 9/6 = 3/2
Any two points on the line will give the same slope because a straight line has a constant slope

The floor of a rectangular room is to be tiled with 1/3 foot square tiles along a 9 3/8 foot wall. How many tiles will be needed along the wall?
Answer: Therefore, approximately 225/8 tiles will be needed along the 9 3/8 foot wall.
Step-by-step explanation:
To determine how many tiles will be needed along the 9 3/8 foot wall, we need to find the number of tiles that can fit in that space.
First, let's convert the mixed number 9 3/8 to an improper fraction. To do this, we multiply the whole number (9) by the denominator (8) and add the numerator (3):
9 * 8 + 3 = 75/8
Now, we have the length of the wall as 75/8 feet.
To find the number of tiles needed, we divide the length of the wall by the length of each tile. The length of each tile is 1/3 foot.
Dividing 75/8 by 1/3, we multiply the first fraction by the reciprocal of the second fraction:
(75/8) / (1/3) = (75/8) * (3/1)
Simplifying the calculation, we get:
(75 * 3) / (8 * 1) = 225/8
Therefore, approximately 225/8 tiles will be needed along the 9 3/8 foot wall.
To tile a 9 3/8 foot wall with 1/3 foot square tiles, 282 tiles are needed.
Explanation:The question is asking how many 1/3 foot square tiles will be needed along a 9 3/8 foot wall in your rectangular room. To find the answer, we first need to convert the length of the wall, which is given in mixed number, into an improper fraction. So, 9 3/8 is equal to 75/8 feet. Since each tile covers 1/3 foot, the number of tiles needed along the wall will be total distance divided by the length covered by each tile.
Therefore, the number of tiles = (75/8) ÷ (1/3) = (75/8) * (3/1) = 281.25
However, because we can't use a fraction of a tile, this number needs to be rounded up. Hence, you'll need 282 tiles to cover the 9 3/8 foot wall.

Between the time Iko woke up and lunchtime, the temperature rose by 11°. Then by the time he went to bed, the temperature dropped by 14°.
Write an addition expression for the temperature relative to when Iko woke up.
Answer: -3 degrees
Step-by-step explanation:
Lets say that the original temperature was "x."
The temperature rose by 11 degrees so it is now at 11+x.
Then the temperature fell by 14 degrees so you subtract. 11+x-14
11-14= -3 so you subtract 3 degrees from the original temperature and there fore the relative temperature is -3

Fuel x costs $2 per gallon and fuel y costs $3 per gallon. You have at most $18 to spend on fuel. Write a system of linear inequalities to represent this situation.
(I did not mean to select one)
Answer:
First choice A : 2x +3y is less than or equal to 18. x greater than or equal to 0. y greater than or equal to 0.
If fuel x costs $2 per gallon, but Fuel y costs $3 per gallon. You may only spend up to $18 on petrol. The system of linear inequalities representing this situation is,2x+3y≤18,x≥0, and y≥0. Option A is correct.
What is inequality?A collection of two or more inequalities in one or more variables is known as a system of inequalities. When there are multiple constraints on a problem's potential solutions and a range of potential solutions are needed, systems of inequalities are used.
Given that, fuel x costs $2 per gallon, but Fuel y costs $3 per gallon. You may only spend up to $18 on petrol.
The maximum or minimum values of a situation with multiple constraints are frequently determined using a system of linear inequalities.
Thus, if fuel x costs $2 per gallon, but Fuel y costs $3 per gallon. You may only spend up to $18 on petrol. The system of linear inequalities representing this situation is,2x+3y≤18,x≥0, and y≥0. Option A is correct.

What is the relationship between
the sine and cosine of complementary angles?
Explain your reasoning and use the relationship
to find cos 50 if sin 40 0.64.
Answer:
0.64
Step-by-step explanation:
Sine and cosine of angles are complimentary
This means
Sin x = Cos (90-x)
Cos x = sin (90 - x)
Therefore sin 40 = 0.64
Sin 40 = cos (90 - 40)
Sin 40 = cos 50
Cos 50 = 0.64

The slope of a line is and the y-intercept is -1/5. What is the equation of the line written in slope-intercept form? Type the equation in the space provided. Be sure to use the slope-intercept form noted in the lesson. Do not type spaces in your answer. If necessary, use the / key to represent a fraction bar.
The equation of the line in slope intercept form is y = mx - 1/5, where m is the slope of the line.
Explanation:The subject of this question is mathematics, specifically geometry, and it pertains to how to write the equation of a line in slope-intercept form given the slope and the y-intercept. However, it appears there was a typographical issue as the slope wasn't provided in the question. Let us assume that the slope of the line is m.
The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. In this situation, if the slope is m and the y-intercept is -1/5, the required equation of the line in slope-intercept form can be written as y = mx -1/5.

Question 6
Name the image of F(-3, 1) after being translated along the vector <5. - 1>.
Answer:
F' (2, 0 )
Step-by-step explanation:
A translation < 5, - 1 > means add 5 to the x- coordinate and subtract 1 from the y- coordinate, that is
F(- 3, 1 ) → F'(- 3 + 5, 1 - 1 ) → F'(2, 0 )
The image of the point F(-3, 1) after being translated along the vector <5, -1> is (2, 0). The process involves adding the vector components to the original point's coordinates.
Explanation:The initial point on the coordinate system is F(-3, 1). A translation moves a point by a specific vector. This vector is <5, -1>, meaning we move the point 5 units to the right and 1 unit down.
To perform the translation, we add the components of the vector to the coordinates of the original point. So, we add 5 to the x-coordinate (-3) and -1 to the y coordinate (1). This gives us the following results:
x-coordinate: -3 + 5 = 2y-coordinate: 1-1 = 0So, the image of F(-3, 1) after being translated along the vector <5, - 1> is the point (2, 0).
