Answer:
see below
Step-by-step explanation:
Since this is written in vertex notation the vertex is (4, 60). The axis of symmetry is equal to the x - coordinate of the vertex which is the vertical line x = 4.
<span>2x^2+10x= -8
</span><span>2x^2+10x+8 = 0
2(x^2 + 5x + 4) = 0
2(x + 4)(x + 1) = 0
x + 4 = 0; x = -4
x + 1 =0; x = -1
answer
x = -4 and x = -1</span>
Answer:
Im sorry i dont have the answer but it is not b.
Step-by-step explanation:
Answer:
Option B
Step-by-step explanation:
-1/2x≥4
1) Multiply both sides of the inequality by the reciprocal of -1/2: (-2)
x≤-8
Graph x≤-8 as a line. Remember that lesser negative values go to the left!
ALSO don't forget when you multiply both sides of an inequality by a negative number the inequality sign flips.
