Answer:
x = -10
Step-by-step explanation:
-2x - 10y = 20 (plug y=0)
-2x = 20
x = 20/-2
x = -10
Answer:
x=9, y=26. (9, 26).
Step-by-step explanation:
x=9
y=3x-1
--------
y=3(9)-1=27-1=26
Answer:
Step-by-step explanation:
a=10 (4,0,2,4,3,1,2,3,1,4)
b=4 (7,5,6,9)
c=6 (13,13,13,10,13,12)
d= 5 (17,16,17,17,16)
e=6 (21,23,20,20,21,23)
Answer: Slope = -2.667/2.000 = -1.333
x-intercept = 5/4 = 1.25000
y-intercept = 5/3 = 1.66667
Step-by-step explanation: Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.667 and for x=2.000, the value of y is -1.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -1.000 - 1.667 = -2.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
EXPLANATION
Price of shoes = $5.50
Markup= 40%
Let's call x to the unknown final price.
The markup percentage relationship is given by the following formula:
Replacing terms:
Multiplying both sides by 5.5:
Dividing both sides by 100:
Adding 5.5 to both sides:
Simplifyng the fraction:
Adding numbers:
Switching sides:
Answer: The final price of the shoes in the deparment store is $7.7
