3x + 2y = 11
y = 5x-1
For this case, the first thing you should do is replace the value of y in the first equation.
We have then:
3x + 2 (5x-1) = 11
We rewrite:
3x + 10x-2 = 11
3x + 10x = 11 + 2
3x + 10x = 13
We clear x:
13x = 13
x = 13/13
x = 1
We now substitute the value of x in expression 2:
y = 5 (1) -1
y = 5-1
y = 4

Answer:
The solution to the system of equations is:
x = 1
y = 4

3x+2 (5x-1)=11
3x +10x -2=11
3x+10x=13
13x=13
X=1

The diameter of a circle is 6 m. Find its area in terms of π π.

Xelga [282]

Step-by-step explanation:

this is totally simple.

the formula for the area of a circle (as you can find with any search on the internet in seconds) :

A = pi×r²

r is the radius.

and once you understand even the most basics of a circle, you know that the radius is half of the diameter.

so, in our case, r = 6/2 = 3 m

the area of the circle is therefore

pi×r² = pi×3² = pi×9 m²

Maria is draining her hot tub at a rate of 5.5 gallons per minute. Is the amount of water left in the pool a function of the amo

AleksandrR [38]

The amount of water in the pool after t minutes is modeled by the linear function $V(t) = V(0) - 5t$ , hence it is a function of time.

A <em>linear function</em> for the amount of water in the pool, considering that it is <u>drained at a rate of a gallons per minute</u>, is modeled by:

$V(t) = V(0) - at$

In which V(0) is the initial volume.

In this problem, draining her hot tub at a rate of <u>5.5 gallons per minute</u>, hence $a = 5.5$ , and:

$V(t) = V(0) = 5.5t$

Which is a function of time.
