Answer: y=1/3x+11/3
Step-by-step explanation:
Since we given the slope, we can write a slope-intercept form equation.
y=1/3x+b
Since we we don't have our y-intercept, we can plug in the coordinate we are given to find the y-intercept.
6=1/3(7)+b
6=7/3+b
11/3=b
Now that we have our y-intercept, we can complete our equation.
y=1/3x+11/3
Answer:
Ratio of online sales to shop sales = 3 : 1
Step-by-step explanation:
Total necklace sold in a month = 240
Necklace sold via shop's website = 180
the rest were sold in a high street shop.
Necklace sold via high street shop = Total necklace sold in a month - Necklace sold via shop's website
= 240 - 180
= 60
Necklace sold via high street shop = 60
Ratio of online sales to shop sales
Necklace sold via shop's website : Necklace sold via high street shop = 180 : 60
= 180 / 60
= 3 / 1
= 3 : 1
Ratio of online sales to shop sales = 3 : 1
Answer:
B. (3, 14).
Step-by-step explanation:
Substitution means that you first solve for one variable, and then use that solution to find the other.
For example, if x = y, and x + 5 = 7, you can say that y + 5 = 7.
Now, moving on to the actual problem.
The first equation says that y = 6x - 4, and the second equation says y = 7x - 7.
That means for the first equation, instead of y, it is valid to say that 7x - 7 = 6x - 4.
7x - 7 = 6x - 4
7x - 6x = -4 + 7
x = 3.
You could put the x=3 into the y = 7x - 7 equation to find what the y-coordinate is.
y = 7 * 3 - 7
y = 21 - 7
y = 14.
And there you have your coordinates! (3, 14).
Hope this helps!
No you add them all together and then you divide the number of GPA's to get the mean. You go from greatest to lowest to figure out the median and to find the mode excepts my mind. <span />
