Solve the system of equations by any method.<br><br><br><br> 5x+9y =16<br> x+2y =4
Alisiya [41]

Answer:

The system of equations has one solution at (-4, 4).

Step-by-step explanation:

We are given the system of equations:

\displaystyle\left \{ {{5x+9y=16} \atop {x+2y=4}} \right.

We can use elimination to solve this system. We need to multiply the second equation by -5 so we can cancel out our x-terms.

-5\times(x+2y=4) \rightarrow -5x - 10y = -20

Therefore, our system now becomes:

\displaystyle\left \{ {{5x+9y=16} \atop {-5x-10y=-20}} \right.

Now, we can add these two equations together and solve for y.

\displaystyle(5x + 9y) + (-5x - 10y) = 0 - y\\\\16 + (-20) = -4\\\\-y = -4\\\\\frac{-y}{-1}=\frac{-4}{-1}\\\\y = 4

Now, we can substitute our value for y into one of the equations and solve for x.

x+2(4)=4\\\\x + 8 = 4\\\\x = -4

Therefore, our final solution is (-4, 4).

Help pls so people say it’s none of these but idk I am confused.
crimeas [40]

Answer:

Volume = \pi r^2 h

2512 = 3.14 × r^2 × 8

r^2 = \displaystyle\frac{314}{3.14}

r^2 = 100

r = 10 \ cm

Diameter = 2r = 20 \ cm

Dont get confused try to understand : )
