4y=x+3
y=1/4x +3/4
as perpendicular, gradient is flipped and made into a minus. so is -4.
y=-4x +c
substitute values in to find c
4=-4 (4)+c
4=-16+c
c=20
y=-4x +20
14 is 20% of 70
30 is 58% of 48
9-10 is 10% of 95
Answer:
.
Step-by-step explanation:
Given : 
= 128.
To find : what is the logarithmic form of the equation in base 10
Solution : We have given that = 128.
By th change base rule ( inverse of exponential function )
= c is equal to 
= b
Then = 128 in to logarithm form 
= x.
Then in to the base 10 logarithmic form.
By the change of base formula 
.
Then , .
Therefore, .
Answer:
c=0.02(m)+30(5)
or
c= 150+0.02(m)
or
c=0.02(m)+150
or
c=30(5)+0.02(m)
Step-by-step explanation:
This is because c, or cost is equal to 30 dollars a day as a base fee or 150 total for five days plus 0.02 per mile. So, if you multiple the mileage driven by 0.02 and add 150 for the 30$ per day at 5 days. This is your equation
These are just different ways you could write that since it is clear you have a multiple choice question
First find the common denominator. It would be 24. For 8 to get to 24 you have to multiply it by 3. So 8*3=24 and 5*3=15. For 6 to get to 24 you have to multiply it by 4. So 6*4=24 and 1*4=4. Our fractions are now at 15/24 and 4/24. 15+4 is 19 and 15-4 is 11. Your answers are 19/24 and 11/24.
