Answer:

2.7 in decimal form and 2 7/10 in fraction form

the picture is kinda all over the place but you basically subtract 1 from 4 and turn 2/7 into a decimal by dividing 2 by 7 and subtracting that answer from 3 (from 4-1)

In the following exercises, multiply the binomials. Use any method.<br> 248. (m + 11)(m − 4)

romanna [79]

Answer:

Hence the expression $(m+11)(m-4)=m^2+7m-44$

Step-by-step explanation:

Explanation

The given expression is (m+11)(m-4).
We have to multiply the given expression.
Multiply the (m+11) by -4, multiply the (m+11) by m then add like terms.

$$$\frac{\begin{matrix}{} & {} & m & + & 11 \\ \times & {} & m & - & 4 \\ \end{matrix}}$

_____________

${\frac{\begin{matrix}{} & - & 4m & - & 44 \\ {{m}^2} & + & 11m & {} & {} \\ \end{matrix}}{\begin{matrix}{{m}^2} & + & 7m & - & 44 \\ \end{matrix}}}$$$

The answer here is A which is the first graph.
Remember that if a is negative in the equation y = ax^2 + bx + c, the parabola always opens downward. For vertex, its coordinates is always located on the first quadrant in which all values are positive.

Write the quadratic equation whose roots are -2 and 3, and whose leading coefficient is 3

KIM [24]

Now, if the roots are -2 and 3, that simply means $\bf \begin{cases}
x=-2\implies &x+2=0\\
x=3\implies &x-3=0
\end{cases}$

now, as far as the leading term's coefficient having a 3, we can simply make it a "common factor" of both terms.

$\bf \begin{cases}
x=-2\implies &x+2=0\\
x=3\implies &x-3=0
\end{cases}\implies (x+2)(x-3)=0
\\\\\\
\stackrel{\textit{common factor}}{3}(x+2)(x-3)=\textit{original polynomial}
\\\\\\
3(x^2-x-6)=y\implies 3x^2-3x-18=y$
