Given the System of Equations:
The exercise asks for solving it graphically. Then, in this case, you need to graph both lines in order to determine the solution of the system.
In order to graph it, you can find the x-intercepts and the y-intercepts:
1. It is important to remember the Slope-Intercept Form of the equation of a line:
Where "m" is the slope of the line and "b" is the intercept.
In this case, you can identify that the y-intercept of the first line is:
And the y-intercept of the second line is:
2. By definition, the value of "y" is zero when the line intersects the x-axis.
Then, you need to substitute the following value of "y" into each equation and then solve for "x", in order to find the x-intercept of each line:
- For the first line, you get:
- For the second line, you get:
3. Now you know that the first line passes through these two points:
And the second line passes through these two points:
4. Knowing those points, you can graph the lines:
Notice that the line intersect each other at
Answer:
x = 12
Step-by-step explanation:
"Using the variable x for unknown number what is five more than the quotient of a number and 6 equals 7" translates into 5 + x/6 = 7.
To solve use inverse operations.
Answer:
The probability that he teleports at least once a day =
Step-by-step explanation:
Given -
Evan lives in Stormwind City and works as an engineer in the city of ironforge in the morning he has three Transportation options teleport ride a dragon or walk to work and in the evening he has the same three choices for his trip home.
Total no of outcomes = 3
P( He not choose teleport in the morning ) =
P( He not choose teleport in the evening ) =
P ( he choose teleports at least once a day ) = 1 - P ( he not choose teleports in a day )
= 1 - P( He not choose teleport in the morning ) P( He not choose teleport in the evening )
=
=
