NOTES: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown."

Generally, the algebraic expression should be any one of the forms such as addition, subtraction, multiplication and division. To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

In what line do planes A and QRV intersect?
BabaBlast [244]

Answer:

Plane A and QRV intersection line is QR.

Explanation:

The plane QRV contains the rectangle QRVN. This rectangle intersects the plane A in the line QR.

Plane A and QRV intersection line is QR.

If one knows a specific line in one plane (for example, two points in the plane), and this line intersects the other plane, then its point of intersection.

Thus, it is on the line of intersection for the two planes.

Cassidy wrote the linear equation y=5x+4 Then, she wrote the equation of the line that is parallel to y=5x+4 and that passes thr
Daniel [21]
Well, again <span>y=5x+4  is in slope-intercept form, therefore    </span>\bf y=\stackrel{slope}{5}x+4.

so then, a parallel line to a line with that equation, will also have the same slope, therefore, what's the equation of a line whose slope is 5 and goes through 8, -2?

\bf \begin{array}{lllll}&#10;&x_1&y_1\\&#10;%   (a,b)&#10;&({{8}}\quad ,&{{ -2}})&#10;\end{array}&#10;\\\\\\&#10;% slope  = m&#10;slope = {{ m}}= \cfrac{rise}{run} \implies 5&#10;\\\\\\&#10;% point-slope intercept&#10;\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-2)=5(x-8)\implies y+2=5x-40&#10;\\\\\\&#10;y=5x-40-2\implies y=5x-42

The perimeter of a rectangle is 73 inches. The perimeter equals twice the length of L inches, plus twice the width of 11 inches.
Sindrei [870]
In mathematical form. you can write it as:
73 = 2 ( l + 11)

We can solve it for length, 
73 = 2l + 22
2l = 73 - 22
l = 51/2
l = 25.5

Hope this helps!

5 ounces of a can of peas is $0.85.
10 ounces of two cans of peas is $1.75.

10 is closer to 11.

So 5 ounces of a can of peas is more reasonable.
