Answer:

Step-by-step explanation:

to make this simple, plug the x-coordinate of each answer choice into x in each of the equations and plug the y-coordinate of each answer choice into y in each of the equations. if BOTH equations come out to be true, this is the solution.

ex:

y=3x-4

y=x+2

plug in (3,5)

5=3(3)-4 is correct

5=3+2 is correct

so, (3,5) is the solution.

Lemur [1.5K]

Answer:

The company's profit made out of selling $6 per unit is $120

Step-by-step explanation:

You basically insert 6 for s and evaluate...

-10(6)^2+110(6)-180, first you multiply the exponents...

-10(36)+110(6)-180, then multiply...

-360+660-180, then simplify...

Andrej [43]

Answer:

3^6

Step-by-step explanation:

We know that A is 3^3 and B is 27 times that.

3•3•3=27

So B is 3•3•3• of 3^3 which is 3•3•3•3•3•3

Work out the area of this semicircle.Take pie to be 3.142 and give your answer to 2 decimal places 10cm

rosijanka [135]

Answer:

The area of the semi circle $A = 157.1 cm^2$

Step-by-step explanation:

Explanation:-

Given radius of circle 'r' = 10 cm

The area of the circle formula

$A = \pi (r)^{2}$

The area of the semi circle formula

$A = \frac{\pi (r)^{2} }{2}$

taking π =3.142

$A = 3.142 X \frac{(10)^2}{2}$

On calculation , we get

$A = 157.1 cm^2$

Final answer:-

The area of the semi circle $A = 157.1 cm^2$
