Answer:
C. y=3/2 x + 12
Step-by-step explanation:
lets find slope,
fr that first lets point out some coordinates passing the line: ( 0, 12 ), ( 2,15 )
now find slope using the equation : y -y1/ x - x1
= 15 - 12 / 2 -0 = 3/2
- use any coordinates now to find the equation of line using formula:
y - y1 = m ( x - x1 )
y - 12 = 3/2 ( x - 0 )
y -12 = 3/2 x - 0
<em>y =</em> 3/2 x + 12
Therefore, y = 3/2 x + 12 is the equation of the line.
the answer is 885 and I used a calculator so you should be good :)
Answer: package B is the better deal.
Step-by-step explanation:
package A offers free phone and 300 minutes. it will cost 0.12 per minute for each minute over the plan time. Also, package A has a base rate of $39.95. This means that if you average 356 minutes per month in talk time, the cost using package A would be
0.12(356 - 300) + 39.95 = $46.67
package B : phone costs $10 and has 350 minutes of time and 0.08 per minute for each minute over the plan time. Also, package B has a base rate of 35.95 not including the phone. This means that if you average 356 minutes per month in talk time, the cost using package B would be
10 + 0.08(356 - 350) + 35.95 = $46.43
Therefore, package B is the better deal since it is cheaper.
Answer:
First number is 6
Second number is 2
Step-by-step explanation:
The trick is that we need to set up two equations. Nor simplicity's sake I'm going to say the first number is x and the second number is y.
First we know that the first number (x) is 4 less than the second number (y).
Less means subtraction.
x-4=y
Then we know that 4 times x is 14 more than 5 times the second. More is addition and times is multiplication.
4x=14+5y
Now we use substitution to find out what x (the first number) is, subbing x-4 in for y.
4x=14+5(x-4)
4x=14+5x-20
-x=-6
x=6
First number is 6
Lastly, we sub 6 back into one of the equations. It's easier to us the first equation.
x-4=y
6-4=y
2=y
The second number is 2
