Answer:
y > 1/3x -3
Step-by-step explanation:
Just find the equation of the line, which is y = 1/3x -3, and then determine what the symbol is going to be. Since the line is dotted, it will either be < or >. When the shaded area is on top of the line, it's >. Remember that by saying left on the bottom or right on top.

Why do scientists use models?
A)
Models are unreliable.
B)
Models waste natural resources.
Models predict not just describe events.
Models are based on scientific laws and principals so they are more
reliable than the real thing.

-3x + 18 = 6
x = ___
show work please
Answer:
x=4
Step-by-step explanation:
-3x + 18 = 6
First, we have to get x alone. So, we have to subtract 18 from 6.
6 - 18 = -12
-3x = -12
-12/-3 = 4
x=4
A local hamburger shop sold a combined total of 488 hamburgers and cheeseburgers on Friday. There were 62 fewer cheeseburgers sold than hamburgers. How
many hamburgers were sold on Friday?
9514 1404 393
Answer:
275
Step-by-step explanation:
Let h represent the number of hamburgers sold. Then the number of cheeseburgers sold is h-62, and the combined total is ...
hamburgers + cheeseburgers = combined total
h + (h -62) = 488
2h = 550 . . . . . . . . add 62, collect terms
h = 275 . . . . . . . . . .divide by 2
275 hamburgers were sold on Friday.

What is the average rate of change for the mold over the 6 days?
Answer:
The average rate of change is 63/6
Step-by-step explanation:
You take the the change from 0 - 6 and 1 - 64 as the changes
the equation is: delta y
delta x
so the average rate is 63/6
1. After running, Maggie is 3 miles east of her starting point, and 4 miles north of her starting point. What angle could represent her direction of travel?
Answer:
The angle is 53.13 degrees
Step-by-step explanation:
Here, we want to calculate angle representing the direction of travel
From the question, she is 3 miles east and 4 miles north of her starting point
So the angle that represents her direction of travel will be that which makes a cut with the horizontal (the east direction)
Now, let us picture a right-angled triangle, with 3 miles direction being the adjacent and the 4 miles direction (facing the angle we want to calculate and is the opposite)
the trigonometric identity to use is the Tangent
Tan theta = 4/3
theta = arc tan (4/3)
theta = 53.13 degrees

Answer:
x = -3
Step-by-step explanation:
System of equations has been given as,
y = 2x + 8
y = [tex]-\frac{2}{3}x[/tex]
Since, solution of the system of equations is the point of intersection on the graph.
Therefore, point of intersection or solution of the system will be,
(x, y) = (-3, 2)
This common point will satisfy both the equations.
And x = -3 will also both the equations.

Step-by-step explanation:
The graph of f (x) = x + 5 is a vertical translation 5 units
up of the graph of f(x) = x. How can you obtain the graph of
f(x) = x + 5 from the graph of f (x) = x using a horizontal
translation?
Answer:
A horizontal translation of 5 units to the left.
Step-by-step explanation:
Given the parent linear function:
[tex]\displaystyle f(x)=x[/tex]
To shift vertically n units, we can simply add n to our function. Hence:
[tex]f(x)=x+n[/tex]
So, a vertical shift of 5 units up implies that n=5. So:
[tex]f(x)=x+5[/tex]
As given.
However, to shift a linear function horizontally, we substitute our x for (x-n), where n is the horizontal shift. So:
[tex]f(x-n)=(x-n)[/tex]
Where n is the horizontal shift.
For example, if we shift our parent linear function 1 unit to the right, this means that n=1. Therefore, our new function will be:
[tex]f(x-1)=(x-1)[/tex]
Or:
[tex]f(x)=x-1[/tex]
We notice that this is also a vertical shift of 1 unit downwards.
Therefore, we want a number n such that -n=5.
So, n=-5.
Therefore, it we shift our function 5 units to the left, then n=-5.
Then, our function will be:
[tex]f(x-(-5))=(x+5)\text{ or } f(x)=x+5[/tex]
Hence, we can achieve f(x)=x+5 from f(x)=x using a horizontal translation by translating our function 5 units to the left.

Answer:
