if all functions are relations, are all relations functions? Explain your answer
Answer:
No, because some relations are not functions. Relations are equations that begin with x=, and let's say x=5.
This is not a function because if you graph this line, it is vertical, and functions can't share the same x coordinate point (input) with other y coordinate points (output). There must be one output for every input, meaning that this relation is not a function.
Step-by-step explanation:
Which of the following best describes the equation below?

Determining Proportionality
Mr. Samuuel Salesman is paid $125 a month. He also earns $50 for every vacuum he sells.
I need to find an equation, a table, and a graph
Answer:
earnings = $125 + ($50/vacuum)x
Step-by-step explanation:
This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:
The equation represents the man's total earnings. The independent variable is x, the number of vacuums he sells.
Thus, earnings = $125 + ($50/vacuum)x. As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).
Plot a black dot at (0, $125). Now move 2 units to the right from this dot and from there up by $100 to (2, $225). Plot this new point. Then draw a line through the two points you've plotted.
Table:
x earnings
---- --------------
0 $125
1 $125 + $50 = $175
2 $125 + $100 = $225
and so on.
pick two anwsers m+(5n)(9-p)-6-r2
Answer:
-5np - r² + m + 45n - 6
Step-by-step explanation:
1) Eliminate redundant parentheses
m + 5n · (9 - p) - 6 - 1r²
2) Rearrange terms
m + 5n · ( - p + 9 ) - 6 - 1r²
3) Distribute
m - 5np + 45n - 6 - 1r²
4) Rearrange terms
-5np - r² + m + 45n - 6

Shape I is similar to shape ll.
*then it’s the picture which is listed below*
The sequence that proves shape l is similar to shape ll when applied to shape l is a reflection across the *x-axis or y-axis* followed by a translation *4, 5, 6, or 7* units right and *2, 3, 4, or 5* units down, and then a dilation by a scale factor of *0.5, 1, 1.5, or 2*.

What is the y-intercept of a line that has a slope of -3 and passes through point (-5, 4)? a) -17 b) -11 c) 7 d) 19
Answer:
(- 11)
Answer b is correct
Step-by-step explanation:
To find this you can use
y = mx + c
Here,
m = slope
c = y - intercept
( -5, 4) = ( x ,y)
Let us solve now .
[tex]y = mx + c[/tex]
[tex]4 = - 3 \times - 5 + c \\ 4 = 15 + c \\ 4 - 15 = c \\ - 11 = c[/tex]
Therefore,
c = (-11)
That means y - intercept is ( -11 )
Hope this helps you.

Answer:
-6.3+d> 4 1/2
Step-by-step explanation:
She starts 6.3 miles west of her home. This is denoted by the (-). The store is 4.5 miles east of her home. East would be denoted by a (+). never be exactly 4.5 miles from her home. This would be denoted by a (>). Therefore the answer is: -6.3+d>4 1/2
The store is more than 4.5 miles east of her home meaning that it would never be exactly 4.5 miles from her home. This would be denoted by a (>). Therefore the answer is: -6.3+d>4 1/2

HELP PLZ ND THX U?!?!?!?!?!?!?!?!?!
Answer:
U = 1
Answer = 6
Step-by-step explanation:
We can do really any number. But in this case, we are gonna do 1. So, it would look like (7 x 1) - 1. It would look like that because we know that 7u is equal to 7 times U or in this case, 7 times 1. So, we know 7 x 1 is 7. Now, we do 7 - 1 since U = 1, and we get our answer of 6.
A recipe calls for 12 lb of flour for 1 batch. How many batches can be made with each of the following amounts?
1 lb
[ Select ]
34 lb
[ Select ]
14 lb
[ Select ]
It could be wrong but I'm pretty sure I'm right.
For 1 pound of flour you cant make any batches or .083 of a batch.
For 34 pounds you can make 2.833 batches.
And finally, 14 pounds of flour gives you 1.166 batches.
To find these answers take your amount of flour and divide it by the 12 pounds of flour.
Example; 34 divided by 12 = 2.833
Example 2; 14 divided by 12 = 1.66
Answer:For 1 pound of flour you cant make any batches or .083 of a batch.
For 34 pounds you can make 2.833 batches.
And finally, 14 pounds of flour gives you 1.166 batches.

What is the change in the amount of water in the pool after 1 1/2 minutes?
Enter your answer as a simplified mixed number by filling in the boxes.
Answer:5 1/5
Step-by-step explanation:
12 1/5 =12.2 as a decimal
12.2 x 1.5 = 18.3
15 2/3 x 1.5 = 23.5
23.5 -18.3 =5 1/5
