Which ordered pair is a solution to the system of linear equation? 2x+ 3y=6 <br> -3x+5y=10

allochka39001 [22]

Answer:

<h3>x = (-2)</h3><h3>y = 2</h3>

Step-by-step explanation:

2x + 3y = 6________( 1 )

-3x + 5y = 10_______( 2 )

( 1 ) × 3 ---- 6x + 9y = 18_____( 3 )

( 2 ) × 2 ---- -6x + 10y = 20_____( 4 )

$(4) + (3) \\ 6x + 9y + ( - 6x + 10y) = 20 - 18 \\ 6x + 9y - 6x - 10y = 2 \\ y = 2$

y = 2 ,

$2x + 3y = 6 \\ 2x + 3(2) = 2 \\ 2x + 6 = 2 \\ 2x = 2 - 6 \\ 2x = - 4 \\x = \frac{ - 4}{2} \\ x = ( - 2) \\$

What is the solution of the matrix equation?

katrin [286]

Hello from MrBillDoesMath!

Answer:

The first choice ( -12, 20)

Discussion:

Using matrix multiplication we find the equations:

1x + 1y = 8 (A)

2x + 3y = 36 (B)

Next, compute

2(A) - B =>

(2x + 2y) - (2x + 3y) = 2*8 - 36 =>

(2x - 2x) + ( 2y-3y) = 16 - 36 =>

-y = -20 =>

y = 20

Substituting this y value in (A) gives

x + 20 = 8 =>

x = 8 - 20 =>

x = -12

The answer is the first choice ( -12, 20)

Thank you,

MrB

When the area in square units of an expanding circle is increasing twice as fast as its radius in linear units

alexira [117]

Answer:

r=1/π

Step-by-step explanation:

Area of the circle is defined as:

Area = πr²

Derivating both sides

$\frac{dA}{dr}$ =2πr

$\frac{dA}{dt}$ = $\frac{dA}{dr}$ x $\frac{dr}{dt}$ = 2πr $\frac{dr}{dt}$

If area of an expanding circle is increasing twice as fast as its radius in linear units. then we have : $\frac{dA}{dt}$ =2 $\frac{dr}{dt}$

Therefore,

2πr $\frac{dr}{dt}$ = 2 $\frac{dr}{dt}$

r=1/π

What's the comparison to 5 + 4

amm1812

6 + 3 or you could do 4.5 + 4.5. but the first one is probably what they're looking for.
