Solve the system of equations -x-2y=0 and -x+y=6 by combining the equations

Mathematics
1 answer:
Elden [556K]3 years ago
3 0

Answer:

x=-4 and y=10

Step-by-step explanation:

Use the second equation to make y=x+6

sub y=x+6 into the first equation

-x-2*(x+6)=0

-x-2x-12=0

-3x-12=0

3x=-12

x=-4

Now sub x=-4 into the second equation

-(-4)+y=6

y=6+4

y=10

What is the equation of y = x^3 with the given transformations? Vertical stretch by a factor of 3, horizontal shift 4 units to t
givi [52]

Answer:

y = 3(x - 4)^3 - 3

Step-by-step explanation:

A vertical stretch factor 3 is given by 3x^3.  Horizontal shift 4 to the right is given by 3(x - 4)^3. Finally we  add -3 to this function to move it 3 units down.

Answer is y = 3(x- 4)^3 - 3
