Elena and Jada each make money by helping out their neighbors.
Elena babysits. Her earnings are given by the equation y=8.40x, where x represents how many hours she works and y represents how much money she earns.
Jada earns $7 per hour mowing her neighbors’ lawns.
A. Who makes more money after working 12 hours? How much more do they make? Explain how you know.
B. What is the rate of change for each situation and what does it mean?
C. How long would it take each person to earn $150? Explain or show your reasoning.
Answer for Part A:
Elena makes more money than Jada does. Elena makes $1.40 more than Jada does.
Explanation for Part A:
The equation for Elena tells us that she makes $8.40 per hour. Jada makes $7 an hour. Since 8.4 > 7, Elena makes more money than Jada per hour

Round your answer to the nearest hundredth.
Answer:
Volume of solid = 737 cm³ (Approx)
Step-by-step explanation:
Given:
Radius r = 4 cm
Length of cylinder = 12 cm
Find:
Volume of solid
Computation:
Volume of solid = Volume of hemisphere + Volume of cylinder
Volume of solid = (2/3)πr³ + πr²h
Volume of solid = (2/3)π(4)³ + π(4)²(12)
Volume of solid = 134 + 603
Volume of solid = 737 cm³ (Approx)
Answer:
737.23
Step-by-step explanation:
formua for sphere:
V = 4/3 πr^3
so the volume would be 268.08
divide by 2 bc its only half of a sphere
you get 134.04
formula for cylinder:
V = πr^2h
so the vlume would be 603.19
add the volumes together you get 737.23

The variable Q varies inversely as the cube of V. FK is the constant of variation, which equation represents this situation?
A. qv^3=k
B. q^3v=k
C. q/v^3=k
D. q^3/v=k
Step-by-step explanation:
When 2 variables are inversely proportional to each other, their product is a constant.
Since Q and V³ are inversely proportional to one another, QV³ = k. (B)

A rectangular field has a length of x metres.
The width of the field is (2x-5) metres.
Show that the perimeter of the field is (6x-10) metres.
The perimeter of a shape is the length of all the sides added together. In this problem, the length of the rectangle is x and the width is (2x-5). With the information given, we want to show that it equals or is equivalent to (6x-10), which is supposed to represent the perimeter of the rectangle.
Before I write my equation I what to make sure you understand that there are of course two side lengths of this rectangle and two widths. That being said, the equation would look like this:
2x + 2(2x-5) = 6x-10
(both side lengths) + (both widths) = perimeter
I'll show you how you can simplify this equation to show that the perimeter of the field is 6x-10 :
2x + 2(2x-5) = 6x-10
(first step would be to distribute the 2 into 2x-5)
2x + 4x-10 = 6x-10
(add the x's on the left side to simplify)
6x-10 = 6x-10
Well well, what do we have here :). We ended up with the same expression on each side of the equal sign. We totally know that they're equivalent, in fact they're the same.
(I honestly really hope this helps. I confused myself a little thinking a lot about this problem. Please let me know if you run into any issues with my answer. I'm pretty sure I'm accurate on the work I showed. I also wasn't able to view your PDF sadly :( )

x^2+12x+36=0 solve using factoring square roots or quadratic formula
Answer:
x = 6
Step-by-step explanation:
Equation: x² - 12x + 36 = 0
Quadratic formula: ax² + bx + c = 0 --> x = (-b ± √(b² - 4ac))/2a
Substitute: x = (12 ± √(12² - 4 * 36))/2
Multiply: x = (12 ± √(144 - 144))/2
Subtract: x = (12 ± 0)/2
Solve: x = 6
write an equation of the line passing through point p(-2,6) that is parallel to the line x=-5
Answer:
The graph of the line x = -2 is also attached below.
Step-by-step explanation:
Given the line
x=-5
x=-5 represents the vertical. We know that the slope of a vertical line is undefined. Thus, the slope of x=-5 is undefined.
Since parallel lines have the same slopes, it means the line which is supposed to be the parallel line to the given line and passing through p(-2, 6) must also be in the form (x = a).
As the line passes through (-2, 6). As the line is vertical, meaning no matter what the value of y is, the x-value remains the same.
Thus, the equation of the line would be x = -2
The graph of the line x = -2 is also attached below.

"Which graph represents the function f(x) = |x| – 4?"
Answer:
the second picture
Step-by-step explanation:
you substitute x=0
into y=abs(x)-4
you get y=0 -4= -4
so x=0 y= -4
look at each graph
then substitute y=0
into y=abs(x) -4
you get 0= abs(x) -4
4=abs(x)
x=4 or x=-4
look at each graph
so you will find it`s graph 2
is love real? why or why not
Answer:
yep
Step-by-step explanation:
love is real, and it's out there, it's just more rare than some people think. love isn't "oh, i love pizza" or "i love you because you did my homework" because those kinds of love are temporary, but passionate, unbreakable love is real, it does exist. i see it in old married couples that have spent so long together, they start acting like one another, i see it in very lucky newlyweds, that have found real love early and will last forever. i see it, i know it's there, just not everyone gets to it, and not everyone understands it, i know i don't.
