Answer:
Step-by-step explanation:
Coordinate points: (18, -7) and (18,2)
m= rise / run or 
m = slope
(x1, y1) = coordinates of first point in the line
(x2, y2) = coordinates of second point in the line
So your rise is...
2 - (-7)
and you run is...
18 -18
Rise = 9
Run = 0
Now, do you see the issue...
You can not have a number over 0 (* a great way to remember is N/0 spells no: "N" being number and "0" being zero)
The slope or the equation 9 / 0 (9 divided by 0 or 9 over 0) is ERROR in the calculator which means the slope of these points are undefined
The line is vertical when this happens
*Side Note: if you were to have 0 as you rise and 9 as your run, 0/9 is ok because that means you have a zero slope meaning that you have a horizontal line
0 divide by 9 is zero
X+40=4x+10
4x-x=40-10
3x=30
x=10 miles
<em><u>Answer: 10 miles</u></em>
Step-by-step explanation:
- First step you take 25 on the other side and when it goes on other side it change the sign to negative 13x< -1-25
- second step you keep the sign of the bigger number then you add. The result will be 13x< -26
- third step you divide both side by 13x÷-26
- finally the answer will be -2
So Jj earns a flat rate of 180 per week and an extra 15 per tablet he has sold
so what we need to do is subtract his flat rate(180) from his total(315)
315
-180
____
135 So now we know how much money Jj has earned from selling tablets. But we still need to create an equation and find out how many he has sold.
So we know he get $15 per tablet so 135÷15=9
now we know he has sold 9 tablets
Bu what is our Equation?
well, what were the steps?
TP = total pay
FR= Flat rate
C= Computer profit
PPC= price per computer
#C = number of computers
#C = TP-FR=C C÷PPC=#C
can we simplify this further?
#C = C÷PPC
lets do this:
#C= x
C= y
PPC= z
So: (X = Y÷Z)
Answer:
d. 19/13
Step-by-step explanation:
tan is the opposite over the adjacent (toa)
the opposite is 19 and the adjacent is 13
19/13
