Answer:
Assuming you want the answer in slope-intercept form, it’s <u>y = -5x + 11</u>
Step-by-step explanation:
So we have to first use point-slope form, y - y1 = m (x - x1)
If we plug the numbers in we get...
y + 4 = -5 (x - 3) (take out parenthesis)
y + 4 = -5x + 15 (now subtract 4 from 15)
<u>y = -5x + 11</u>
I think this is right
Answer:
399 minutes a month
Step-by-step explanation:
As I understand the question the answer would, in other words, be how many minutes you can long-distance call with the economy plan for under $30.
The unit ratio is 5 cents per minute, which equates to 20 minutes worth of call time for one dollar (100/5).
The economy plan is $20 cheaper than the deluxe plan. $20 spent on long-distance calling gets you 400 mintues, but the question asks for an integer that would still leave remaining money.
Therefore the answer is 399 minutes of long-distance calling, which would leave five unspent cents.
So...we can write eqn as
40x = 50(x-1)
so. -10x=-50
so. x=5
therefore .... the distance of 40 lb will be 5 ft ...answer !!!
First you need to fill in the variables with what you already know, so
t=2m+40.
You don’t have enough information to solve this problem. You need to have only 1 variable to solve it or you need more information
