Answer:
Step-by-step explanation:
x<-14
Answer:
x < -14 is correct.
Step-by-step explanation:
Here is the work:
x - 2 > 2x + 12
I will start by getting rid of the 2x , so subtract 2x from both sides.
-x -2 > 12
Add 2 to both sides.
-x > 14.
Multiply by negative 1 on both sides because -1 times -1 is 1, so you get 1x (x).
When multiplying by a negative, you switch the sign around.
x < -14.
the diagonals of a rhombus are 16 cm and 12cm. find its length
Answer:
l=10 cm
Step-by-step explanation:
In a rhombus, the diagonals are cut into identical lines at the intersection.
This way, I found the measures of the halves of the diagonals in a right triangle, knowing that the diagonals of the rhombus are perpendicular on each other.
I calculated that AO = AC/2= 8, and that BO=BD/2= 6, and then I applied pytagora's theorem in a quarter of the rhombus, which is the right triangle AOB, to find the length of a side
Write a function that represents the relationship between X and y shown in the graph below
Answer:
y = 3x - 10
Step-by-step explanation:
Find the slope of the line by calculating the Rise/Run between any two points. I picked (-2,-16) and (4,2).
The Rise is = (2-(-16))=18
The Run is = (4 -(-2)) = 6
Rise/Run is 18/6 = 3. The slope is three:
y = 3x + b
b is the y-intercept, the value of y when x=0. b is - 10 in this graph.
y = 3x - 10 is the line of this graph.

Help, I know you could find the slope on any two points but the way they graphed it made it super confusing, is this supposed to trick me?
Answer:
Slope=10.25 (rate of change)
Step-by-step explanation:
(7, 71.75) and (4,41)
(41 - 71.75) / (4 - 7) = 10.25

Ann works as a tutor for $9 an hour and as a waitress for $8 an hour. This month, she worked a combined total of 94 hours at her two jobs.
Lett be the number of hours Ann worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.
Answer:
Ann earned $752+x in a month
If you take t as hours he worked as tutor then ,
Money earned will be $752+t
Answer:
earnings = 752 +t
Step-by-step explanation:
If Ann worked t hours as a tutor, then she worked (94-t) hours as a waitress. Her total wages were ...
earnings = waitress wages + tutor wages
earnings = 8(94 -t) + 9(t)
earnings = 752 +t . . . . . . . simplify

what are the zeros of the polynomial function ? f(x) = 2x (x-2) (1-x)
Answer:
The zeros are 0 ,2, and 1
Step-by-step explanation:
f (x) = 2x (x - 2) (1 - x)
set f(x) equal to y
y = 2x (x - 2) (1 - x)
solve when y is 0 because when y is 0 then it is an x-intercept
0 = 2x (x - 2) (1 - x)
separate all of the equations out
0 = 2x
0 = (x - 2)
0 = (1 - x)
solve for x for each equation
0 = 2x
divide both sides by 20/2 = 0 and 2x/2 = x0 = xx = 00 = (x - 2)
add 2 to both sides0 + 2 = 2 and (x - 2) + 2 = x2 = xx = 20 = (1 - x)
subtract 1 from both sides0 - 1 = -1 and (1 - x) - 1 = -x-1 = - xmultiply both sides by -1-1 · -1 = 1 and -x · -1 = x1 = xx = 1Which expression forms an equation with the given expression; 24 - 5 x 2

what is the answer to 5a+3b=c
Answer:
a = -0.6b + 0.2c
Step-by-step explanation:
Simplifying
5a + 3b = c
Solving
5a + 3b = c
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3b' to each side of the equation.
5a + 3b + -3b = -3b + c
Combine like terms: 3b + -3b = 0
5a + 0 = -3b + c
5a = -3b + c
Divide each side by '5'.
a = -0.6b + 0.2c
C=
5/9

Maximillan is cleaning shrimp. He cleans 4 shrimp every minute. Use time in minutes as the independent quantity, x, and the number of shrimp as the dependent quantity, y.
1. Identify the unit rate of this relationship. Explain what the unit rate means in terms of this situation.
2. Write an equation that demonstrates the number of shrimp cleaned per minute.
3. Is the relationship proportional or non-proportional? Explain how you can determine this using the graph and the equation.
Answer:
1. 1:4
2. y = 4 x X
3. yes
Step-by-step explanation:
1. every 1 minuet he cleans 4 shrimp
2. y is the number of shrimp and x is the time. if every miuet he cleans 4 shrimp, then that means you have to multiply the shrimp by the minuets. for example, if he spends 2 minuets, he cleans 8 shrimp because 2 x 4 = 8.
3. This is a proportional relationship because if you were to put this on a graph, it would be a strait line. for example, if you were to plot x (the time) on a line (this line would go horizontal) and y (shrimp) on the line (this line goes verticle) 1 minuet = 4 shrimp. 2 minuets = 8 shrimp. 3 minuets = 12 shrimp. 4 minuets = 16 shrimp.
i hope this helps. tell me if this is too confusing or if you need more help. have a great day :)
One moving company charges 100$ plus 10$ per hour. Another company charges $50 plus $15 per hour. At what number of hours will the charge by both companies be the same?
