Mathematics
1 answer:
Sindrei [870]2 years ago

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 !

What is <br> the equation of the line that passes through the points (-6,6) and (-1,-9)
IgorLugansk [536]

Answer:

The answer to the question provided is y = -3x - 12.

Step-by-step explanation:

❃Incase you forgot what the linear equation formula is ☟

y = mx + b

❃Incase you also forgot, what the slope formula is ☟

m = \frac{y_2 - y_1 }{x_2 - x_1}

➊ First: We are going to be solving for the slope.

m = \frac{  - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3

➋Second: We find the y-intercept.

y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{  - 18 =  - 18 \: \: \: \: \:  \:  \:  \:  \:  \:  \:  \: }{ - 12 = b}

➌Third: Plug in.

y =  - 3x - 12

How do you solve this?
masha68 [24]
Here's what i found online:

<span>a/3+4=6

We simplify the equation to the form, which is simple to understand
<span>a/3+4=6

Simplifying:
<span> + 0.333333333333a+4=6

We move all terms containing a to the left and all other terms to the right.
<span> + 0.333333333333a=+6-4

We simplify left and right side of the equation.
<span> + 0.333333333333a=+2

We divide both sides of the equation by 0.333333333333 to get a.
<span>a=6

Hope this helped :-)</span></span></span></span></span></span>
