(-6/5, -8/5), you substitute 3x+2 for the y in the first equation. So the first equation will read 2x+3x+2, then you solve and get x= -6/5. Then you have to solve for y, so you put your x value (-6/5) in the second equation for x. it should read y= 3(-6/5)+2, the answer to that is y= -8/5. After that you just put them in order (x,y) and there's your answer.

Please help me with this question on algebra

grandymaker [24]

The solution is option D.

0     4
- 6     1
3    -4

Rember rows times columns.

=>
a11 = 4*0 + 0*(-3) = 0

a12 = 4*1 + 0*1 = 4 + 0 = 4

a21 = -1*0 + 2*(-3) = 0 - 6 = -6

a22 = -1*1 + 2*1 = -1 + 2 = 1

a31 = -3*0 + (-1)*(-3) = 0 + 3 = 3

a32 = -3*1 + (-1)*1 = -3 - 1 = -4

6. The revenue function for a production by a theatre group is

Sidana [21]

Answer:

When the ticket price is $3 or $4 the production will be in break even

Step-by-step explanation:

<u><em>The correct question is</em></u>

The revenue function for a production by a theatre group is R(t) = -50t^2 + 300t where t is the ticket price in dollars. The cost function for the production is C(t) = 600-50t. Determine the ticket price that will allow the production to break even

we know that

Break even is when the profit is equal to zero

That means

The cost is equal to the revenue

we have

$R(t)=-50t^2+300t$

$C(x)=600-50t$

Equate the cost and the revenue

$-50t^2+300t=600-50t$

solve for t

$-50t^2+300t+50t-600=0$

$-50t^2+350t-600=0$

Solve the quadratic equation by graphing

using a graphing tool

the solution is t=3 and t=4

see the attached figure

therefore

When the ticket price is $3 or $4 the production will be in break even

When a problem involves more than one unit for a characteristic (such as length), now can you tell which unit is more appropriat

Lostsunrise [7]

Answer:

For larger measurements, we use larger unit while for smaller measurement we use smaller unit.

Step-by-step explanation:

Normally, For larger distances we make use of larger units while for smaller distances we make use of smaller units.

For example, if we consider the distance travelled by a person in some days;

For 15000 units distance; We can represent this value as 15 Kilometers

For 800 units distance; Rather than using kilometers, it would be better to represent it in meters as 8 meters.

Also, For 70 units distance; Instead of kilometers or meters, 70 cm would be a better unit of representation.

Likewise, If we consider some 3 dimensional shapes holding some substances,

For 7000 units, best unit of weight representation would be 7 Kg

For 600 units, instead of in kg, best unit of weight representation would be 600 grams

For 50 units, best unit of weight representation would be 50 grams

So, looking at the examples given in both weight and distances, we will conclude that for larger measurements, we use larger unit while for smaller measurement we use smaller unit.
