Answer:
y = 7x - 48
Step-by-step explanation:
To find the equation of the line
y = mx + c
Step 1 : find the slope
( 6, -6) ( 8, 8)
x_1 = 6
y_1 = -6
x_2 = 8
y_2 = 8
Insert the values into
m =( y_2 - y_1) /( x_2 - x_1)
m - slope
m = (8 - (-6)) / (8 -6 )
m = 8 +6 / 8 - 6
m = 14 / 2
m = 7
Step 2: substitute slope into intercept form equation
y = mx + c
y = 7x + c
Step 3: substitute either point into the equation in step 2
y = 7x + c
Let's pick point ( 8,8)
y = 8
x = 8
y = 7x + c
8 = 7(8) + c
8 = 56 + c
8 - 56 = c
c = 8 - 56
c = -48
Substitute the value of c back into the equation
y = 7x + c
y = 7x - 48
The equation of the line is
y = 7x - 48
Jo's Mobile Plan:
Fixed monthly charge = £16
Monthly 150 free minutes, post that 13p (or £0.13) per minute,
Monthly 150 free texts, post that 15p (or £0.15) per text
Jo's mobile phone usage details:
170 minutes of calls
182 texts
Total Charges for Jo = Fixed Monthly Charge + Charges for Calls + Charges for Texts
⇒ Total Charges for Jo = 16 + (170-150) × 0.13 + (182-150) × 0.15
⇒ Total Charges for Jo = 16 + (20) × 0.13 + (32) × 0.15
⇒ Total Charges for Jo = 16 + 2.6 + 4.8
⇒ Total Charges for Jo = 23.4
Hence, Jo should be charged £23.4 for the month.
Hope this helps !
Answer:
1 minute
Step-by-step explanation:
10 divided by 10 is = to 1 so 1 frog catch 1 fly in 1 minute
1. 3 cans of cat food for $0.85
This is really simple division once looked at (I took the decimal out of the equation, so I will add it back later):
85/3=28.333…
Since it can't be rounded, it remains as 28, which means that the correct answer is $0.28/can of cat food, once the decimal placement has been refactored.
2. 14 ounces of Olive Oil for $3.59.
359/14=25.642
Since this term is able to be rounded, it becomes 26, since we're rounding to two numbers. Now, we put the decimal back where it was taken out earlier, and we learn that the answer is <span><em>$0.26/ounce of Olive Oil.</em>
</span>4. 4 pairs of socks for $11.00.
1100/4= 275
This time, there is nothing to round, so after the decimal has been put back in its original spot, the answer becomes <em>$2.75/pair of socks.</em>
