Y= -2x²-3x+2, (form y = ax² +b .x + c
The parabola opens downward & hence it's Vertex is a MAXIMUM.
We know that the axis of symmetry is -b/2a ==>3/(-4) ==>
x= - 3/4 (axis of symmetry. At x=-3/4 , y = 25/8 = 3.125
Hence the axis of symmetry is x= - 3/4 & the vertex is at (-3/4, 25/8)
Answer:
we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
Step-by-step explanation:
Given the expression
SECOND STEP
subtract 3 from the right-hand side as well as on the left-hand side
SOLVING THE REMAINING COMPLETE COMPRESSION
Divide all parts by -2
- Please note that multiply or divide an inequality by a negative number flips the inequality sign.
so the expression becomes
Hence, from the explanation, we conclude that in the second step, 3 should have been subtracted from the right side as well on the left side.
Answer:
The slope is 4 and the y intercept is -5/2
Step-by-step explanation:
8x-2y = 5
Solve for y to get the equation in slope intercept form
Subtract 8x from each side
8x-8x-2y =-8x+ 5
-2y = -8x+5
Divide by -2
-2y/-2 = -8x/-2 + 5/-2
y = 4x -5/2
This is in slope intercept form y= mx+b where m is the slope and b is the y intercept
The slope is 4 and the y intercept is -5/2
