Hence, the answer is yes.The equation 2x = 50-3x can be solved by graphing y = 2x and y=50-3x,
Use the drop-down menu to complete the statement to explain why a graph can be
used to solve this equation. Answer
The solution of the equation is x = 10. The graph is attached below.
We are given an equation. The equation has one variable. The equation is given below.
2x = 50 - 3x
First of all, we will solve the equation directly to find the solution.
2x = 50 - 3x
5x = 50
x = 10
The above equation can be also be solved by graphing y = 2x and y = 50 - 3x. These are two linear equations. These equations represent two straight lines. The solution is found by locating the intersection point of these two straight lines on the graph. The graph of the two straight lines is attached below.

if the perimeter is 28 and part of it is 5 what is the cm
The other side of the rectangle is 9 cm.
Given that:-
Perimeter of the rectangle = 28 cm
One side of the rectangle = 5 cm
We have to find the other side of the rectangle.
Let the length of the rectangle be 5 cm and,
The breadth of the rectangle be b cm.
We know that,
Perimeter of the rectangle = 2(l + b)
Hence, we can write,
2(5 + b) = 28
5 + b = 28/2
5 + b = 14
b = 14 - 5
b = 9 cm
Hence, the other side of the rectangle is 9 cm.

What is the slope of the line that passes through the points (12, -13) and (-18, 11)? Round your answer to the nearest tenth.
The slope of the line is 0.8.
What is slope of the line?
The slope of a line is also called its gradient or rate of change. The slope formula is the vertical change in y divided by the horizontal change in x, sometimes called rise over run. The slope formula uses two points, (x1, y1) and (x2, y2), to calculate the change in y over the change in x.
slope of the line = (y2-y1)/x2-x1
Here, the points are (12,-13) and (-18,11)
x1=12,y1=-13, x2=-18, y2=11
m (slope of line) = 11+13/(-18-12)

Omar and Devin both leave the bookstore at the same time, but in opposite directions. If Devin travels 7 mph faster than Omar and after 3 hours they are 93 miles apart, how fast is each traveling?
Omar and Devin both leave the bookstore at the same time, but in opposite directions.
Let the speed of Omar = x
Speed of Devin = x + 7
They travel for 3 hours
Speed = Distance/Time
Distance = Speed x Time
Since, they are 93 miles apart
93 = (speed pf Omar + Speed of Devin) Time
93 = (x + x + 7)3
93 = (2x + 7)3
93 = 6x + 21
93 - 21 = 6x
6x = 72
x = 72/6
x = 12
Thus, Speed of Omar is 12 mph
Speed of Devin : x + 7
x + 7 = 12 + 7
= 19
Thus, speed of Devin is 19mph

Answer:
you have to solve the system:
1)W=L-6
2)W*L=72
so (L-6)*L=72
L^2-6L-72=0
(L-12)*(L+6)=0
so the answers for L are 12 and -6,but we only consider 12 cause there can't be -6miles. so L=12
and W=12-6, so W=6.
Answer:
Width = 6mi
Length = 12mi
Step-by-step explanation:
Let's say our length = x
Since the width is 6 miles less than the length, width = x - 6
The area of rectangle is width x length so just substitute your values
(x - 6)(x) = 72
therefore: x^2 - 6x = 72
*subtract 72 to form a quadratic equation
x^2 - 6x - 72 = 0
*solve by factorising
(x+6)(x-12) = 0
therefore x = -6 or 12
Since you can't have a negative length, x = 12
thus, our length is 12mi
To find the width, just subtract 6 which = 6mi
So: length = 12mi and width = 6mi
how would I graph the line, 3x+4y= -4
Given the equation:
3x + 4y = -4
Let's graph the line that represents the equation above.
To grah the line, rewrite the equation in slope-intercet form:
y = mx + b
Where m is the slope and b is the y-intercept.
Rerite the equation for y:
3x + 4y = -4
Subtract 3x from both sides:
3x - 3x + 4y = -3x - 4
4y = -3x - 4
Divide all terms by 4:
[tex]\begin{gathered} \frac{4y}{4}=-\frac{3x}{4}-\frac{4}{4} \\ \\ y=-\frac{3}{4}x-1 \end{gathered}[/tex]The slope of the line is -3/4, while the y-intercept is at (0, -1).
Now, let's graph the line using 3 points.
• When x = -4:
Substitute -4 for x and solve for y
[tex]\begin{gathered} y=-\frac{3}{4}\ast(-4)-1 \\ \\ y=3-1 \\ \\ y=2 \end{gathered}[/tex]• When x = 0:
Substitute 0 for x and solve for y
[tex]\begin{gathered} y=-\frac{3}{4}\ast(0)-1 \\ \\ y=-1 \end{gathered}[/tex]• When x = 4:
Substitute 4 for x and solve for y
[tex]\begin{gathered} y=-\frac{3}{4}\ast4-1 \\ \\ y=-3-1 \\ \\ y=-4 \end{gathered}[/tex]Therefore, we have the following points:
(-4, 2), (0, -1) and (4, -4)

How many different values can a 16-bit binary number store? How many digits are needed fora hexadecimal number to do the same? How about a base-5 number? Show your work.
A very simple way to know the number of possible combinations in a binary number is given by the next formula:
[tex]2^n=2^{16}=65536^{}[/tex]Now, we should remember that an hexadecimal number contain 16 different digits, from 0 to F. Therefore
[tex]\begin{gathered} 16^n=65536 \\ n\ln 16=\ln 65536 \\ n=\frac{\ln 65536}{\ln 16} \\ n=4 \\ 16^4=65536 \end{gathered}[/tex]Thus, we will need 4 hexadecimal numbers to achieve the same values as a 16-bit number.
For the base-5 number we can do a similar procedure:
[tex]\begin{gathered} 5^m=65536 \\ m\ln 5=\ln 65536 \\ m=\frac{\ln 65536}{\ln 5} \\ m=6.89\approx7 \\ 5^7^{}=78125 \end{gathered}[/tex]Therefore, we would need at least 7 numbers base-5 to achieve something similar to 16-Bit number

i)
The vertex form of a quadratic equation of a parabola opening upwards or downwards is,
[tex]y=a(x-h)^2+k\ldots\ldots(1)[/tex]Here, (h,k) is the coordinates of the vertex of the parabola. If a is positive, the parabola is facing up and if a is negative, the parabola is facing down.
The given equation of parabola is,
[tex]y=(x+2)^2-5\ldots\ldots(2)[/tex]So, the given equation is in the vertex form of the quadratic equation.
Comparing equations (1) and (2), we get
a=1, h=-2, k=-5.
Since a is positive, the parabola opens upwards. The coordinates of the vertex of the parabola is (-2,-5).

Determine the equation of the line that passes through the point (1/−3,−9) and is perpendicular to the line 5y+x=1.
Given the following equation of a line:
[tex]5y+x=1[/tex]We will write the equation in the slope-intercept form: y = m x + b
[tex]\begin{gathered} 5y+x=1 \\ 5y=-x+1 \\ \\ y=-\frac{1}{5}x+\frac{1}{5} \end{gathered}[/tex]Now, we will find the equation of the line that is perpendicular to the given line.
Note: if the slope of the given line = m
So, the slope of the perpendicular line = -1/m
From the given line: slope = m = -1/5
So, the slope of the perpendicular line = -1/m = 5
The required line passes through the point (-1/3, -9)
We will use the point-slope form to write the equation of the required line:
[tex]\begin{gathered} (y-k)=m*(x-h) \\ \\ y-(-9)=5*(x-(-\frac{1}{3})) \\ \\ y+9=5x+\frac{5}{3} \end{gathered}[/tex]Simplify the equation to be like the standard equation:
[tex]\begin{gathered} y+9=5x+\frac{5}{3}\to\times3 \\ 3y+27=15x+5 \\ \\ 3y-15x=-22 \end{gathered}[/tex]So, the answer will be:
3y - 15x = -22
