One solution
<h2>
Explanation:</h2>
For a system of linear equations in two variables, we could have three possible cases:
<h3>Case 1. No solution.</h3>
This happens when the lines are parallel and have different y-intercepts.
<h3>Case 2. One solution.</h3>
This happens when the lines intersect at a single point.
<h3>Case 1. Infinitely many solutions</h3>
This happens when the lines are basically the same having the same slope and y-intercept.
So, let's rewrite our lines in Slope-intercept form 
:
As you can see, they have different slopes and y-intercepts. So they will intersect at a single point which is the solution of the system. By using graphing tool we get that this point is (1.5, -1) as indicated in the figure below.

The two triangles are congruent by ~
- B.) HL congruency criteria
Because each triangle have a right angle (90°), a pair of equal sides and their hypotenuse are equal as well, because they have a common hypotenuse ~

So let’s say the equation is x^2 (x squared) -4x + 8 = 0. So you have to eventually graph a palabara. So to get the vertex, you have to find the line of symmetry (this plays a big part). So the formula for the line of symmetry is x= -b/2a. So A is this equation is 1. B is -4. C is 8. So you would plug these numbers in and you get 2. So (2,0) is your like of symmetry. Now you have to plug 2 back in for x. So when you do that you get 4 so the vertex is (2,4). So the vertex is (2, 4) and basically what the vertex is is it is the highest or lowest point of a palabara. So you can tel if it opens up or down by looking is A is negative or positive. If A is negative the it opens down. If it is positive then it opens up. So now you just put points in. Create a t chart. Like x/y. So when X is 1 for example, y is 5. So you graph (1, 5) and you graph the point that is the same distance from the line of symmetry. You do this until you have 5 points. I hope this helps. It’s hard to teach this over text.
Answer:
a ≤ 2
Step-by-step explanation:
Simplify both sides of the inequality
42a + 48 ≤ 132
Subtract 48 from both sides
42a + 48 − 48 ≤ 132 − 48
42a ≤ 84
Divide both sides by 42
42a/42 ≤ 84/42
a ≤ 2
