The 2 to the power of 2 add the 4 will be in the parenthesis. This is just a tip for you, just try the parenthesis where you think is right and do the math. If it is not right then move the parenthesis.
Answer:
Step-by-step explanation:
-2 + 2(3) =-2 +6 = 4 for the 2nd equation
2(-2) + 4(3) = -4 +12 = 8 for the 2nd equation
(-2,3) satisfies both equations
let x = 0, then y= 2 (0,2) is another solution
there's multiple solutions, including (-2,3) and (0,2). That eliminates all answers except the first
Try graphing the two equations. They're the same line, with an infinite number of points on the line, which means an infinite number of solutions.
Answer:
The right values of y :
5 , 3 , 5
Step-by-step explanation:
Let f be the function of equation : y = 1/2x² + 3
then f(0) = 1/2(0)² + 3 = 0 + 3 = 3
f(2) = 1/2(2)² + 3 = 2 + 3 = 5
f(-2) = 1/2(-2)² + 3 = 5
Answer:
(5x³+3x²-5x+4) + (8x³-5x²+8x+9)
= 5x³+3x²-5x+4 +8x³-5x²+8x+9
= 5x³+8x³+3x²-5x²-5x+8x+4+9
= 13x³-2x²+3x+13
