Answer: (3,4)

multiply both sides of the top equation by 2

get rid of the x variable by subtracting add all corresponding numbers and variables (4+(-4), -4+7, -4+16) which leaves you with 3y=12

divide both sides by 3 which cancels out the 3y and leaves you with y=4

input y in your top equation to find x. (-2x+2x4=2)

this leaves you with x=3

I HOPE THAT MADE SENSE!!!

I need hellllppp plsssss​
bagirrra123 [75]

Answer:

a_7=-15

Step-by-step explanation:

a_n  is given as the nth term of a sequence.

We want to find a_7 , which means we find the 7th term of the sequence.

Here, we simply substitute "7" into "n" of the formula given for  a_n  to find the value of the 7th term of the sequence.

We show this below:

a_n=-3(n-2)\\a_7=-3(7-2)\\a_7=-3(5)\\a_7=-15

So the 7th term is "-15"

A cylindrical rainwater tank is 1.5 m tall with a diameter of 1.4 m. What is the maximum volume of rainwater it can hold??
Ket [755]

To work out the volume of a prism, you multiply the area of cross-section by the height (or length).

So for a cylinder, you work out the area of the circle and then multiply it by the height.

Area of circle (or cross-section) = π × radius²

                                                = π × 0.7²

                                                = 0.49π   m²

Now to get the volume of the cylinder, you times this area of the cross-section by the height of the cylinder:

Volume = 0.49π × 1.5

            = 2.3 m³  (accurate to 2 decimal places)

---------------------------------------------------------------

Answer:

The maximum volume of rainwater the cylinder can hold is:

<u> </u><u>2.3 </u><u>m³</u>
