It actually depdens on which one you set for x and y
let's say that x=number of televisions sold
y=number of copmuter sold
72x+90y=profit
wants to make at least 360
72x+90y≥360
graph
one way is to find the x and y intercepts, first solve for '=' and not '≥'
x intercept, set y=0
72x=360
x=5
x intercept at (5,0)
yintercept
set x=0
90y=360
y=4
yiint at (0,4)
garph the points (5,0) and (0,4) and connect those points with aline
see witch side to graph one
is (0,0) in the solution set?
0≥360
false
it is not
shade on the side that it isn't on
we have
90x+72y≥360
that underline tells us that (0,5) and (4,0) are possible solutions
hmm
see each
the answer is A, if we do x=computers and y=TV, then D is also acceptable
answer is A
Answer:
17/40
Step-by-step explanation:
4/5-3/8=32/40-15/40
=17/40
Y = kx - <span>y varies directly as x in this function
</span>
- y varies inversely as x in this function
For
y varies directly as x
For
y varies inversely as x
Answer:
25 million mosquitoes
Step-by-step explanation:
maximum possible number = 25
The slope of this line is -2.
rise/run
rise = 4
run = -2
4
------- = -2
-2
Using the points (1,0) & (0,2)
2 - 0 2
----------- = ----- = -2
0 - 1 -1
