Write the equation in slope-intercept form. What are the slope and y-intercept?
Schach [20]
Slope intercept form is y=mx+b

Y= y intercept
M = slope
B = x intercept

-2x-11y= 5              get the y by itself
-11y = 2x + 5            divide by -11



y = -2/11x + 5/11

slope is -2/11

kicyunya [14]

Answer:

y = 4(10.30+1.50)

Step-by-step explanation:

Since there are 4 people, you and 3 others, you would multiply everything by 4. Inside the parenthesis, would be the nachos and a drink that everyone got. Since all four people got the same thing, it would be 4x10.30 + 4x1.50, which together would be y = 4(10.30+1.50)

Use the graph of f(x) below to estimate the value of f '(3):
klio [65]
Well, looking at the graph, notice, its vertex is at 0,9, and it passes through the points -3,0 and 3,0, so hmm let's use 3,0, to get the equation of f(x)

\bf ~~~~~~\textit{parabola vertex form}
\\\\
\begin{array}{llll}
\boxed{y=a(x- h)^2+ k}\\\\
x=a(y- k)^2+ h
\end{array}
\qquad\qquad
vertex~~(\stackrel{}{ h},\stackrel{}{ k})\\\\
-------------------------------

\bf vertex~(0,9)~
\begin{cases}
h=0\\
k=9
\end{cases}\implies y=a(x-0)^2+9
\\\\\\
\textit{we also know that }
\begin{cases}
x=3\\
y=0
\end{cases}\implies 0=a(3-0)^2+9
\\\\\\
-9=9a\implies \cfrac{-9}{9}=a\implies -1=a\quad thus\quad \boxed{y=-x^2+9}
\\\\\\
\left. \cfrac{dy}{dx}=-2x \right|_{x=3}\implies -6

The question in the image! Please hurry :D
sergey [27]

Answer:

While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.
