Answer:
Increasing
Step-by-step explanation:
We know that Jennifer earns $9 dollars per hour babysitting, this is the only information provided. Meaning that the monetary value is constantly increasing, with no fees or anything being mentioned, this means that the function is increasing. Due to the situation, the line on the graph will always go up.
Jennifer's equation could be represented as 9x.

Find a and b if the points p(6,0) and q(3,2) lie on the graph of ax + by =12
Answer:
[tex]a= 2[/tex]
[tex]b = 3[/tex]
Step-by-step explanation:
Given
[tex]p(x,y) = (6,0)[/tex]
[tex]q(x,y) = (3,2)[/tex]
[tex]ax + by = 12[/tex]
Required
Find a and b
In [tex]p(x,y) = (6,0)[/tex], [tex]x = 6[/tex] and [tex]y = 0.[/tex]
This gives:
[tex]a*6 + b*0 = 12[/tex]
[tex]6a = 12[/tex]
Divide by 6
[tex]a= 2[/tex]
In [tex]q(x,y) = (3,2)[/tex]. [tex]x = 3[/tex] and [tex]y = 2.[/tex]
This gives:
[tex]a*3 + b*2 = 12[/tex]
[tex]3a + 2b = 12[/tex]
Substitute 2 for a
[tex]3*2 + 2b = 12[/tex]
[tex]6 + 2b = 12[/tex]
Collect Like Terms
[tex]2b = 12 - 6[/tex]
[tex]2b = 6[/tex]
Divide by 2
[tex]b = 3[/tex]

a man has 290 ft of fencing to build the pen shown in the illustration. If one in is a square, find the outside dimensions.
the dimensions are feet(smaller value) by feet (larger value)
9514 1404 393
Answer:
40 ft by 85 ft
Step-by-step explanation:
The total length of the three "vertical" partitions is ...
3x = vertical partitions
The total length of the horizontal sides is ...
2(x +(x +5)) = 4x +10
Then the perimeter is ...
P = vertical partitions + horizontal sides
290 = 3x +4x +10
280 = 7x
x = 40
2x+5 = 85
The overall dimensions are 40 ft by 85 ft.

Q1. x = 11, y = 5Q2. x = 22, y = 123Step-by-step explanation:
Question 1B and E are congruent as corresponding angles
11x - 4 = 11711x = 121x = 11AB = DE as corresponding sides
17y - 8 = 12 + 13y17y - 13y = 12 + 84y = 20y = 5Question 2Sum of interior angles = 180
2x + 13 + 3x + 57 = 1805x = 180 - 705x = 110x = 2257 and y make a straight angle
y = 180 - 57y = 123Step-by-step explanation:

If twelve inches correspond to 30.48 centimeters, how many centimeters are there in thirty inches?
Answer:
76.2 cm
Step-by-step explanation:
Do 30.48 / 12 to find the amount of centimeters per inch. 30.48 / 12 = 2.54
So, for ever inch, there are 2.54 cm. Now to find the amount of centimeters in thirty inches, do 2.54 x 30 = 76.2.

Why is it easier to use regression to predict the behavior of an index versus an individual stock?
Hello, I am BrotherEye
Answer:
Regression models are predictive tools. If you want to use them to predict the behavior of an individual, you must set "behavior" as your dependent variable, and you must have indicators and measures for such. You must also identify your explanatory or independent variable likewise you must have indicators and measures for such.
If you have built your model on the basis of collected data, you will be able to predict the value of behavior given a value of the explanatory variable.

A 10-gal aquarium is 4 in. higher than it is wide. Its length is 17 in., and its volume is 4284 in.^3. What are the height and width of the aquarium?
Answer:
[tex]W = 18[/tex] -- Width
[tex]H = 14[/tex] --- Height
Step-by-step explanation:
Given
[tex]V = 4284[/tex] -- Volume
[tex]L = 17[/tex] -- Length
[tex]H = ??[/tex] -- Height
[tex]W = 4 + H[/tex] -- Width
Required:
Find the height and the width
Volume is calculated as:
[tex]V = LWH[/tex]
This gives:
[tex]4284 = 17 * (4+H) * H[/tex]
[tex]4284 = 17 * (4H+H^2)[/tex]
Open bracket
[tex]4284 = 17 * 4H+17*H^2[/tex]
[tex]4284 = 68H+17H^2[/tex]
Divide through by 17
[tex]252 = 4H+H^2[/tex]
Write as a quadratic expression
[tex]H^2 + 4H - 252 = 0[/tex]
Expand
[tex]H^2 + 18H - 14H - 252 = 0[/tex]
Factorize:
[tex]H(H + 18) - 14(H + 18) = 0[/tex]
Factor out H + 18
[tex](H - 14)(H + 18) = 0[/tex]
[tex]H -14 = 0[/tex] or [tex]H + 18 = 0[/tex]
[tex]H = 14[/tex] or [tex]H = -18[/tex]
But Height can not be negative. So:
[tex]H = 14[/tex]
Recall that:
[tex]W = 4 + H[/tex]
[tex]W = 4 + 14[/tex]
[tex]W = 18[/tex]
A triangle with area 40 square inches has a height that is four less than six times the base. Find the base and height of the triangle
Answer:
A = 1/2bh
Step-by-step explanation:
40 = (.5)(6x - 4)(x)
40 = (3x-2)(x)
40= 3x^2 - 2x
3x^2 -2x - 40 =0
3x^2 - 12x + 10x - 40 = 0
3x(x - 4) + 10(x -4) = 0
(3x + 10)(x - 4) = 0
x = {4 , - 10/3}
x = 4 , b = 20. h = 4
Answer:
Step-by-step explanation:
Width=4 inches
Height= 20 inches

6x²-12x-25=-7
vertex
axis of symmetry
Answer:
Step-by-step explanation:
-b
The axis of symmetry can be calculated using this formula: x = ------
2a
-(-12)
which in this case is x = ---------- = 1. The axis of symmetry is the vertical
2(6) line x = +1
Thus, x = 1 is the x-coordinate of the vertex. Normally we'd find the y-coordinate by evaluating the function at x = 1. Unfortunately your
6x²-12x-25=-7 does not have the form of a quadratic function; such a function does not have the " = " sign in it.
Example: Suppose we have 6x²-12x-25 = f(x) and we evaluate this function at x = 1: f(1) = 6(1)^2 - 12(1) - 25 = -31, which (in this example)
leads to the vertex (1, -31).
