2x = 4y + 8, x - 2y = 4

Evgen [1.6K]

Answer: x = 8, y = 2, coordinates (8,2)

Step-by-step explanation:

2x = 4y + 8 (divide by 2 to get value of x)

x = 2y + 4

(now substitute x into the second equation to find value of y)

2y + 4 - 2y = 4

2y - 2y = 4 - 4 (divide by 2 to get value of y)

y - y = 2 - 2

y = 2

Now plug in value of "y" to get value of "x".

x - 2(2) = 4

x - 4 = 4

x = 8

Coordinates (8,2)

Is there a prime number that ends in zero?

Ilia_Sergeevich [38]

No, because all numbers that end in zero are able to be divided by sometimes 2, and always 5. And 0 doesn't count as a prime number.

Calculate the average rate of change of y=x2+3x−2 on the interval 1≤x≤2

Artyom0805 [142]

Answer:

The rate of change for the given function is 6.

Step-by-step explanation:

Given function is:

$y = x^2+3x-2$

The interval on which we have to find the rate of change is:

1≤x≤2

Here

a = 1

b = 2

We have to find the values of function on both points

Putting 1 in place of input (x)

$y_a= (1)^2+3(1)-2\\= 1+3-2\\=2$

Putting x = 2

$y_b = (2)^2+3(2)-2\\= 4+6-2\\=8$

The rate of change is calculated by using the following formula

$Rate\ of\ change = \frac{y_b-y_a}{b-a}\\=\frac{8-2}{2-1}\\= \frac{6}{1}\\=6$

Hence,

The rate of change for the given function is 6.
