Answer:
m = 1 / 4
Step-by-step explanation:
m = y2-y1 / x2-x1
m = 8-7 / 8-2
m = 1 / 4
<span>B. -6y = 12 is the asnwer</span>
Answer:
x=5
y=6
Step-by-step explanation:
If you add the two, it turns into 2y=12. That means y=6. So then x would equal 5 if you bring y into one of them.
The vertex form of this equation is f(x) = (x + 4)^2 - 3
In order to change an equation from standard form to vertex form, you must use a process called completing the square. To use this follow the steps below.
f(x) = x^2 + 8x + 13
Start by subtracting the constant from both sides.
f(x) - 13 = x^2 + 8x
Now take half of the coefficient of the x term and square it. Since the x term has a coefficient of 8, we take half of it (4) and square it (16). Now we add that to both sides.
f(x) - 13 + 16 = x^2 + 8x + 16
f(x) + 3 = x^2 + 8x + 16
Now that you've done these two steps, you can factor the right side into a perfect square.
f(x) + 3 = (x + 4)^2
And then we subtract the new constant from both sides.
f(x) = (x + 4)^2 - 3
Answer:
Her commission for item 1:
<em>5</em><em>%</em><em> </em><em>of </em><em>2</em><em>,</em><em>0</em><em>0</em><em>0</em><em> </em><em>=</em><em> </em>100
Her commission for item 2:
<em>5</em><em>%</em><em> </em><em>of </em><em>9</em><em>,</em><em>8</em><em>0</em><em>0</em><em> </em><em>=</em><em> </em>490
Total commission for each item;
<em>Item </em><em>1</em><em> </em><em>:</em><em> </em>2,000
<em>Item </em><em>2</em><em> </em><em>:</em><em> </em>9,800
