Here is a equation. Find x. (2+x)5=11

Nady [450]

I am pretty sure the answer is 3.5.

(2+x)5=11

(2+x)=11/5

(2+x)= 5.5

x= 5.5-2

x= 3.5

Kuta Software - Infinite Algebra 2 Name Systems of Two Equations Date Solve each system by graphing. 1) y=-3x + 4 y= 3x - 2 2) y

gogolik [260]

Answer:

Solution of the system of equations: (1, 1)

x = 1, y = 1

Explanation:

Given the below system of equations;

$\begin{gathered} y=-3x+4 \\ y=3x-2 \end{gathered}$

Note that the slope-intercept form of the equation of a line is given as;

$y=mx+b$

where m = slope of the line

b = y-intercept of the line

Comparing the given system of equations with the slope-intercept equation, we can see that, for the 1st equation (y = -3x + 4), the slope(m) = -3 and y-intercept(b) = 4 and for the 2nd equation, slope(m) = 3 and y-intercept(b) = -2.

Knowing the above information, let's go ahead and graph the system of equations;

From the above graph, the point of intersection of the two lines (1, 1) is the solution of the system of equation.

How many sides does a parallelogram have? OA) 2 OB) 4 OD 6

KonstantinChe [14]

Answer:

OB: 4 sides

Step-by-step explanation:

A parallelogram has 4 sides. It is a flat shape with opposite sides parallel and equal in length. Opposite angles are equal.

In the picture below, angles "a" are the same, and angles "b" are the same.

In the case of a parallelogram where all angles are right angles, is a rectangle.

the pitch, or frequency, of a vibrating string varies directly with the square root of the tension. if a string vibrates at a fr

Naily [24]

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
\begin{array}{llll}
\stackrel{frequency}{f}\textit{ of a vibrating string varies directly}\\
\qquad \qquad \textit{with the square root of the tension }\stackrel{tension}{t}
\end{array}$

$\bf f=k\sqrt{t}\quad \textit{we also know that }
\begin{cases}
f=300\\
t=8
\end{cases}\implies 300=k\sqrt{8}
\\\\\\
\cfrac{300}{\sqrt{8}}=k\implies \cfrac{300}{\sqrt{2^2\cdot 2}}=k\implies \cfrac{300}{2\sqrt{2}}=k\implies \cfrac{150}{\sqrt{2}}=k
\\\\\\
\textit{and we can \underline{rationalize} it to }\cfrac{150\sqrt{2}}{2}\implies 75\sqrt{2}=k$

$\bf thus\qquad f=\stackrel{k}{75\sqrt{2}}\sqrt{t}\implies \boxed{f=75\sqrt{2t}}\\\\
-------------------------------\\\\
\textit{now, when t = 72, what is \underline{f}?}\qquad f=75\sqrt{2(72)}$
