Answer:
-2.5x-.5
draw the dotted line (3/7)x-3 and shade below it
Step-by-step explanation:
First, we need the slope
Use the slope formula:
so we have
y= -2.5x+b
Solve for b by plugging in coordiantes
-8= -2.5(3)+b
-8= -7.5+b
b= -.5
Put it together and get -2.5x-.5
2.)
A line is parallel to another line if they have the same slope (and different y intercepts)
So in the formula y=mx+b we knowe that m= 2/3
Now it's just a matter of solving for B
plug in the required coordinate to do this
-1=(2/3)*0+b
-1= b
Put it all together to get
3.)
put this into slope intercept form
3x-7y>21
3x-21 > 7y
(3/7)x-3 >y
To graph this just draw a dotted line with the equation (3/7)x-3 and shade everything below it (use de_smos if you're stuck)
First change the mixed number into a fraction greater than one 1 1/2= 3/2, then divide 2 into 3 which results in 1.5
Answer:
Step-by-step explanation:
The number of miles that he ran last week is m.
His goal this week was to run one mile more than twice the miles he ran last week. This means that his goal this week is
m + 2m = 3m
If he tripled his goal, it means that the number of miles that he ran this week would be
3 × 3m = 9m
An expression in simplest form to show how many more miles he ran this week compared to last week would be
9m - m = 8m
The last gas station she stopped at she got 6.6 gallons and paid $20.39
If they lower the price by 6%, that means she would pay 94% of the original amount ( 100% - 6% = 94%)
Multiply the amount she paid by 94%:
20.39 x 0.94 = 19.17
She would pay $19.17 total.
Now divide that by the number of gallons bought:
19.17 / 6.6 = $2.90 per gallon ( Rounded to the nearest cent).
Product means to multiple so I think it's rs
