Because you know the equation for what x is, you can substitute (2y+12) for x. Your new equation would look like this;

2(2y+12)+3y=-11

Distribute the 2 into 2y+12

4y+24+3y=-11

Add 4y and 3y

7y+24=-11

Subtract 24 from both sides

7y=-35

y=-5


Now, substitute -5 in for y in the 2nd equation.

x= 2(-5)+12
x=-10+12
x=2


x=-5
y=2

Anyone know how to solve this??
Tom [10]

Given : \frac{(x^\frac{2}{5})^9\;.\;(x^\frac{-4}{15})}{x^\frac{1}{3}}

\implies {(x^\frac{18}{5})\;.\; (x^\frac{-4}{15})}\;.\;(x^\frac{-1}{3})

\implies x^(^\frac{18}{5} ^-^\frac{4}{15}^-^\frac{1}{3}^)

\implies x^(^(^\frac{54 - 4}{15}^)^-^\frac{1}{3}^) = x^(^(^\frac{50}{15}^)^-^\frac{1}{3}^) = x^(^(^\frac{10}{3}^)^-^\frac{1}{3}^) = x^(^\frac{9}{3}^) = x^3

\implies x^k = x^3

\implies k = 3

Help: The equation is in the screenshot
Svetllana [295]

The graph of the function shows that function f(x) => ∞ as x = -∞ and f(x) =>-∞ as x = ∞. Option c is correct.


<h3>What is a graph?</h3>

The graph is a demonstration of curves that gives the relationship between the x and y-axis.


Here,
The curve of the function in the 2 quadrants is increasing when x tends to -∞ and in the quadrant, the curve f(x) is decreasing to -∞ as x tends to ∞.


Thus, the graph of the function shows that function f(x) => ∞ as x = -∞ and f(x) =>-∞ as x = ∞. Option c is correct.
