Eric is hiring a company to install carpeting in his house. The company charges a one-time installation fee plus a certain amount per square yard of carpeting. The graph below shows the relationship between the number of square yards of carpeting and the total cost, in dollars.
A. Slope of the graph
B. Y-intercept of the graph
C. Domain of the function
D. Range of the function
Answer:
As axjames said, it is A. Slope of the graph.
Step-by-step explanation:
A slope in a graph can mean a increase or a decrease in whatever. For example a decrease in miles per hour (mph), business sales, and more. Also don't forget slopes with decrease are negative slopes and slopes with increase are positive slopes. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right. It's important to note that we work from left to right when dealing with slope.
The graph of a linear equation is a straight line.
The quantity that represents the cost per square yard of carpeting is the (a) slope of the graph.
The slope of the graph is the rate of change of the total cost over the change in square yard.
This means that:
The slope of the graph is the cost per square yard of the carpet.
Hence, the required quantity is (a)

What polygon is formed by
joining the points
(1, −1), (4, −1), (−1, −3),
and (7, −3)?
Answer:
the polygon is a trapezoid
Step-by-step explanation:
(1, −1), (4, −1), the two points having the same y coordinate they make a horizontal line
(−1, −3), (7, −3) the two points having the same y coordinate they make another horizontal line
All horizontal lines are parallel.
The shape is a trapezoid because it has one pair of parallel lines.

B. The graph of f(x) is horizontally compressed by a factor of 5 and
shifted 12 units up.
C. The graph of AX) is vertically compressed by a factor of 5 and
shifted 12 units up.
D. The graph of f(x) is horizontally stretched by a factor of 5 and
shifted 12 units to the left.
SUBMIT
Answer:
The answer is A. when you compress horizontally you take it by a factor of 1/a. in this case a=5. 12 is your k value and k decides whether or not you shift up or down, because k is positive or is upward by 12

What is the value of x in the equation ? (In the picture I included)
Answer:
X = 8⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
Answer:
Step-by-step explanation:
[tex]13x-\dfrac{1}{2}(4x + 50) = 8x - 1\\\\13x -\dfrac{1}{2}*4x - \dfrac{1}{2}*50 = 8x - 1[/tex]
13x - 2x - 25 = 8x - 1
11x - 25 = 8x - 1
11x = 8x - 1 + 25
11x = 8x + 24
11x- 8x = 24
3x = 24
x = 24/3
x = 8

Step-by-step explanation:
(a−2b)

\{ - 2 - (2 \times - 12) \}{−2−(2×−12)}
\{ - 2 - ( - 24)\}{−2−(−24)}
\{ - 2 + 24 \}{−2+24}

the required value is 22
The simplified value of (a−2b)³ is 10648.
What is equation?Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.
Parts of an Equation
There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.
given:
(a−2b)³
and, a=−2 and b=−12
Now, substituting the values
(a−2b)³
= ((-2)−2(-12))³
= (-2 + 24)³
= 22³
= 10648
Hence, the simplified value is 10648.

Solve the given equation: 49 = 7^(x+1) *
Answer:
x = 1
Step-by-step explanation:
49=7^x+1
Let's take the log of both sides
(x+1)*(log(7))=log(49)
x + 1 = log (49) / log (7)
x + 1 = 2
subtract 1 from both sides
x = 1

Write a rule to describe each transformation: #10 & #12
Answer:
Step-by-step explanation:
10
You are rotating the the triangle 180 degrees about the origin. The rule for that is (x,y) ----> (-x,-y)
So X starts at (-4,1) and rotates until it hits (- - 4, -1 or (4,-1). Question is that where X' is? Yes.
Now try the next two points
W(-3,-4) ------> W'(- - 3, - -4) = W'(3,4)
Y(-1,-2) =====> y'(- - 1 , - - 2) = Y'(1,2)
Is that where these points are? Yes it is
12
This given triangle GFH rotates 90 anticlockwise. The rule for that (x,y) ===>(-y,x)
This means that you interchange x and y and make the y value minus. All you have to do is obey the rule.
F(-3,0) becomes F'(0,-3)
G(4,0) becomes G'(0,-4)
H(-3,3) becomes H'(-3,-3)
What should you be convinced of? You should think there is no stretch taking place -- the triangles are not getting bigger or smaller. You should see that the shape remains the same. If you cut both out with a pair of scissors and put one on top of the other, you could not tell which came from where.Answer:
10) (x, y) ⇒ (-x, -y) . . . . rotation 180° about the origin
12 (x, y) ⇒ (-y, x) . . . . . rotation 90° CCW about the origin
Step-by-step explanation:
10) The order of the points WXY is CW in both figures, so no reflection (or an even number of reflections) across a line will be involved. Each image point is the same distance from the origin as its preimage point, so no dilation is involve. Those distances are in opposite directions, so rotation 180° about the origin is indicated.
The transformation describing that is ...
(x, y) ⇒ (-x, -y)

12) The order of points GHI is CW in both figures, so reflection across a line is not involved. Each image point is the same distance from the origin as its preimage, so no dilation is involved. The direction from the origin is different by 90°, so there has apparently been a 90° CCW rotation about the origin. This transformation is described by the rule ...
