Answer:
-2x² + 15
Step-by-step explanation:
Step 1: Add like terms
4x² - 6x² = -2x²
-10x + 10x = 0
3 + 12 = 15
Step 2: Rewrite
-2x² + 15
Idk what that answer is but good luck
Answer:
Answer:
A
Step-by-step explanation:
A
when multiplied out
the highest exponent of x is 2
y = 2x² + x - 6
Answer:
<h2>NONE OF THEM</h2>
Step-by-step explanation:
From the graph,
y and x intercepts are
and approximately
respectively
for A, C and D : 
x intercept the value of y=0, and y intercept x=0.
x and y intercepts are
and approximately
respectively
for B: 
x and y intercepts are
and approximately
respectively
Therefore x and y intercepts for the lines
and
they are not equal to the x and y intercepts of the given graph
