What is -3x+3y=6 3x+5y=-46

Mathematics
1 answer:
Mademuasel [1]3 years ago
5 0

Answer:

x = -7 , y = -5

Step-by-step explanation:

Solve the following system:

{3 y - 3 x = 6 | (equation 1)

3 x + 5 y = -46 | (equation 2)

Add equation 1 to equation 2:

{-(3 x) + 3 y = 6 | (equation 1)

0 x+8 y = -40 | (equation 2)

Divide equation 1 by 3:

{-x + y = 2 | (equation 1)

0 x+8 y = -40 | (equation 2)

Divide equation 2 by 8:

{-x + y = 2 | (equation 1)

0 x+y = -5 | (equation 2)

Subtract equation 2 from equation 1:

{-x+0 y = 7 | (equation 1)

0 x+y = -5 | (equation 2)

Multiply equation 1 by -1:

{x+0 y = -7 | (equation 1)

0 x+y = -5 | (equation 2)

Collect results:

Answer: {x = -7 , y = -5

What are the characteristics of the function f(x)=2(x-4)^5? Check all that apply
GaryK [48]

Answer:

Option B , C , E are characteristics of the function .

Step-by-step explanation:

Given : function f(x)=2(x-4)^5.

To find : What are the characteristics of the function .

Solution : We have given that f(x)=2(x-4)^{5}.

By the End Point behavior : if the degree is even and leading coefficient is odd of polynomial of function then left end of graph goes down and right goes up.

Since , Option E is correct.

It has degree 5 therefore, function has 5 zeros and atmost 4 maximua or minimum.

Option C is also correct.

By transformation rule it is vertical stretch and shift to right (B )

Therefore, Option B , C , E are characteristics of the function .

The differential equation dy dx equals the quotient of the quantity x plus 1 and y minus 3
Phantasy [73]

Answer:

I only

Step-by-step explanation:

dy/dx = x + 1 / y -3

(y - 3)dy = (x + 1) dx

integrate

1/2y^2 - 3x = 1/2x^2 + x

1/2y^2 = 1/2x^2 + 4x

y^2 = x^2 + 8x

y = (x^2 + 8x)^1/2
