Answer:
10 yrs
Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
x = -7y/10 + 718/5
F(x) would be x value
Solution would be y value
a. (-1,1)
b. (2,7)
c. (1,-1)
c. (2,0)
Answer:
C is the equation that is perpendicular and goes through the given point.
Step-by-step explanation:
In order to find this, we first need to find an equation with the appropriate slope. Perpendicular lines have opposite and reciprocal slopes. Since the slope of the original line is 1, we need a line with -1 slope. C and D are the only such answers that have this slope.
Next we look for it to fit into the following point slope equation.
y - y1 =m(x - x1)
We use the point (2, 5) as (x1, y1). So we can plug those in the spots that we see above as well as the slope at m.
y - y1 =m(x - x1)
y - 5 = -(x - 2)
Answer:
YES, the equipment should be purchased
Step-by-step explanation:
You borrow $10000 for the piece of laboratory and the cost of money is 12%. After 3 years you will need to pay the $10000 you borrowed and the extra amount caused by the interest. 12% of $10000 if $1200, so you will end up having to pay $10000+$1200 = $11200. In three years your equipment saves you $4000*3 = $12000, which is bigger than the amount you have to pay. So, in the end the equipment should be purchased because it gives you a gain of $800.
