If the lines are parallel (have the same slope but different intercepts) . . .
no solution, because they never cross.
If the lines have different slopes . . .
one solution, because they have exactly one common point.
If the lines have the same slope and the same intercept . . .
infinitely many solutions, because every point on one line is also a point on
the other line, one lays right on top of the other, and when you look at them on
the graph, it looks like only one line.
Answer:
c
Step-by-step explanation:
252 = 7 *36
36 = 6 *6 = 6²
a² -b² = (a + b)(a - b)
7h² - 252k² = 7(h² - 36k²)
= 7(h² - [6k]² )
= 7(h +6k)(h - 6k)
Answer:
=m2+6mn+9n2
Step-by-step explanation:
=(m+3n)(m+3n)
=(m)(m)+(m)(3n)+(3n)(m)+(3n)(3n)
=m2+3mn+3mn+9n2
We are asked to solve for the monthly income given that 30% of it goes to your expenses.
Expenses per month = $702.38
Expenses percent from income = 30% = 0.3
Total income per month = X
The solution is shown below:
$702.38 = 30% * X
X = $702.38 / 0.3
X = $2,341.27
The total income is $2,341.27.
The easiest way is to make equations y=2400x+30000 and y=2000+36000
and then put that in the calculator and go to table and the point they intersect at is (15,66000)
