Answer:
reflections across the x axis and a shift down 3 units
Step-by-step explanation:
y = x^2
The negative sign means it is a reflection across the x axis y = −f(x)
y = -x^2
The subtraction of 3 means we are shifting down 3 units
y = -x^2 -3
1 is the correct answer my guy
So there are two ways.
First you could solve for y and plug it into the calculator. one equation for y1 and another for y2. Then go 2nd trace and press 5 and then press enter 3 times to find the intersection.
the second way is to solve by hand. I would suggest solve the first equation for y and plug the equation solved for y into the other equation. so y = -3x + 9 and 3x-5y=15. Then you could do 3x - 5(-3x+9) = 15. Finally solve for x and plug in x into both equations to see if you get the same y value.
The answer should be (10/3, -1)
Answer:
2y + 4z = x
Step-by-step explanation:
Given



Required
Write an equation that which is true for the above parameters
<em>This question will be answered using trial by error method and the solution is not limited to one equation.</em>
<em></em>
One equation that matches the values above is:.

To check:
Substitute the values of x, y and z in the above equation.




Hence,
Because both sides of the equation are one and the same (-4),
is true for the above values of x, y and z.
