Two linear equations can have no solutions, exactly one solution or infinitely many solutions. There will be no solution if the lines are parallel on a graph. There will be exactly one solution if the lines intersect each other on a single point. And finally, there will be infinite solutions if the lines overlap each other perfectly.
A single line however has infinite ordered pair solutions as the line travels infinitely in both directions on the coordinate plane. For example, using the equation y=3x, for any real value of x, we will get a real value for y.
Linear inequalities with two variables have infinitely many solutions. We can use the inequality y>3x as an example. For any real value of x, we will get a real value for y.
I hope this helps!
D. 989 sq.m should be the right answer
Answer:
There is a 9/15 or 3/5
Step-by-step explanation:
There are a total of 15 cards, of those, 6 are red, so if you subtract 6 from 15, you get 9, which is the total amount of yellow and blue cards, which is what you were to not get a red card.
Answer: -3 < or = -j < -7
Step-by-step explanation:
-1 < or = 2-j < -5
-1 -2 < or = -j < -5-2
-3 < or = -j < -7
sorry about the sign.
Answer:
Step-by-step explanation:
1. Approach
Divide the given figure up into two simple figures, a trapezoid, and a rectangle. Calculate the area of each figure by using their respective area formula. Then add up the results to get the value for the area of the entire figure.
2. Area of the trapezoid
The first figure is a trapezoid, calculate its area by using the following formula,
Where parameters (
) and (
) represent the base of the trapezoid, and (
) represents the height. Substitute in the given values and solve.
Simplify,
3. Area of the rectangle
The other figure formed by the partition of the two figures is a rectangle. The formula to find the area of a rectangle is the following,
Where (
) represents the base of the figure, and () represents the height of the figure. Substitute in the values for the given parameters and solve,
Simplify,
4. Find the total area
Now add up the values for the area of each figure. The result will be the total area of the figure,
Substitute,
Simplify,
