Solve the following system: y = x 3 4x y = 18 (6, 3) (3, 6) (â’3, 6) (3, â’6).

Nastasia [14]

The solution of the given equation is (3,6). The correct option is B.(3,6)

<h3>Given equations,</h3>

$y=x+3.......(1)\\4x+y=18.....(2)$

<h3>How to solve the equations?</h3>

putting the value of y from equation (1) in equation (2) , we get

$4x+x+3=18\\$ $5x=18-3\\5x=15\\x=3$

substitute the value of x=3 in equation (1) we get,

$y=3+3\\y=6$

Hence, the solution of given equation is (3,6).

So, the correct option is B.

Which point-slope equation represents a line that passes through (3,-2) with a slope of -4/5?

Viefleur [7K]

Answer:

y + 2 = -4/5 (x - 3)

Step-by-step explanation:

y - y1 = m (x - x1). Put in your points for y1 and x1, and always remember to flip your signs.

unfortunately, I don't know why that isn't one of your answers, so sticking with the positive 2 I would choose y+2=- (- 3) if I were you. Looks like the -4/5 disappeared somehow?

Hope this helps

Answer:

417.62

$A=πr(r+\sqrt{x} h2+r2)$ Step-by-step explanation:

because radius is half of diameter and then you would use this equation to solve
