Leviafan [203]2 years ago
7 0

Answer:

x=-1, y=2

Step-by-step explanation:

Plug the y=-2x into the second equation in place of the y to get 4x+10(-2x)=16

Simplify this to 4x-20x=16 then to -16x=16

Divide both side by -16 to get x=-1

Plug x=-1 into the first equation to get -2(-1)=y

Simplify to get y=2

Answer:

Split the number into the whole number component and fraction component.

5 8/25= 5+8/25.

Multiple =4.

Multiply the numerator and the denominator by the multiple 4.

8×4/ 25×4.

Simplify.

32/100=0.32

Combine the whole number component with the decimal.

Answer:

x= 1

Step-by-step explanation:

x = 1 is the axis of symmetric for the graph

if we draw a line parallel to the y axis one units to the right side of the origin we get the line of symmetry of the graph.

and since the line of symmetry is parallel to y axis and passes thru the point (1, 0) it's equation is x= 1
