The denarius was a unit of currency in ancient Rome. Suppose it costs the Roman government 10 denarius per day to support 3 legi

Romashka [77]

Answer:

We can not solve for a unique cost for each soldier.

Step-by-step explanation:

Let x be the daily cost for legionaries and y be the daily cost for archers.

Upon using our given information we will get a system of linear equations as:

$3x+3y=10...(1)$

$x+y=3...(2)$

Now we will solve for x from our 2nd equation,

$x = 3-y$

Now we will substitute this value in our 1st equation.

$3(3-y)+3y=10$

$9-3y+3y=10$

We can see that -3y cancels out with 3y and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.

sladkih [1.3K]

9 = 6y + 33
9 - 33 = 6y
6y = 9 - 33
y = $\frac{ - 24}{6} = - 4$

Which equation has a slope of -2 and passes through the point (1,-6)?

Naily [24]

Answer:

y=-2x-4

Step-by-step explanation:

Given that,

Slope, m = -2

It passes through the point (1,-6).

We need to find the equation of line that passes throgh the given point. It can be calculated as:

$y-y_1=m(x-x_1)$

Put y₁ = -6, x₁ = 1 and m = -2

$y-(-6)=(-2)(x-1)\\\\y+6=-2x+2\\\\y+2x+6-2=0\\\\y=-2x-4$

Hence, the equation of line is y=-2x-4.
