Change these equations into the equations of linear functions.
\left \{ {{4x-2y=22} \atop {6x+9y=-3}} \right. \\ \\
 \left \{ {{-2y=-4x+22} \atop {9y=-6x-3}} \right. \\ \\
 \left \{ {{y=2x-11} \atop {y=-\frac{2}{3}x-\frac{1}{3}}} \right.

Draw function graphs and read coordinates of the intersection.
\left \{ {{x=4} \atop {y=-3}} \right.

Equation C: y = 2x + 8
ExtremeBDS [4]

Answer:

No solution

Step-by-step explanation:

we have

y=2x+8 -----> equation C

y=2x+2 -----> equation D

Comparing equation C and equation D

The two lines are parallel  because the slope is equal ( m=2)

The y-intercept are different

so

The lines are different parallel lines

therefore

The system of equations has no solution

multiply. (2.5×10−8)(9×10−10) express your answer in scientific notation. all of the ones with - is to the power of a. 2.25×10−1
svetlana [45]
(2.5 x 10^-8)(9 x 10^-10) = (2.5 x 9) x (10^(-8 + (-10))) = 22.5 x 10^(-8 - 10) = 2.25 x 10^1 x 10^-18 = 2.25 x 10^(1 + (-18)) = 2.25 x 10^(1 - 18) = 2.25 x 10^-17
