Step-by-step explanation:
2x - 4y = 32
2x - 8y = 48
2x - 2x - 4x - (-8y) = 32 - 48
4x = -16
x = -16 ÷ 4
x = -4
substitute your value of x into any of the original equations
2 (-4) - 4y = 32
-8 - 4y = 32
-4y = 32 + 8
-4y = 40
y = 40 ÷ -4
y = -10
Answer:
Exact form: x=31/3
Decimal Form: x=10.¯
3
Mixed Number Form: x=10 1/3
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
<h3>The lines are perpendicular</h3>
Step-by-step explanation:
We determine whether lines are parallel or perpendicular by getting their slopes
For line 1; (1, 0), (7, 4)
Slope m = 4-0/7-1
M1 = 4/6
M1 = 2/3
Hence the slope of M1 is 2/3
For Line 2; (7, 0) , (3, 6)
M2 = 6-0/3-7
M2 = 6/-4
M2 = -3/2
Take the product of the slopes
M1 * M2 = 2/3 * -3/2
M1M2 = -1
Since the product of their slope is -1, hence the lines are perpendicular
For this case we have a function of the form:
y = A (b) ^ x
Where,
A: initial amount
b: growth rate
x: time (in months)
We have the following equation:
f (x) = 15 (3) ^ x
We observed that:
b = 3
Therefore, the number of bees triples each month.
Answer:
b = 3
the number of bees triples each month.
