Answer:
- 3x + 4 = 9x -6
- 3x + 4 = 3x + 5
- 9x + 6 = 9x + 6
Step-by-step explanation:
Let x is the variable in each type of equation
1/ an equation that has one solution:
3x + 4 = 9x -6
<=> 9x - 3x = 4+6
<=> 6x = 10
<=> x = 
2/ an equation that has no solution:
3x + 4 = 3x + 5
<=> 3x - 3x = 5-4
<=> 0 = 1 impossible
3/ an equation that has infinite many solutions:
9x + 6 = 9x + 6
<=> 9x - 9x = 6 -6
<=> 0 = 0 (obvious) no matter what we put in for x
Hope it will find you well.
I believe that the quadrilateral formed would be a kite. With the diagonal that forms 2 congruent triangles being from point (0,9) to (0,1)
Answer:
It's asking you to find the inputs of the function.
Step-by-step explanation:
Basically, when you input something, you replace "x" in the equation with the number you want to input. For example, if I had the equation: 5x/6+5, then I wanted to input "5", then 5 would replace x in the equation, making 5(5)/6+5. The output they are giving you is simply evaluating the equation that you used to input x, so basically in the case I gave you, the output would be 5(5)/6+5, or 25/6+5, and 55/6. Using the outputs, they want you to find the inputs.
Answer:
Step-by-step explanation:
Sides of the figure = n = 7
<h3><u>Formula for measuring the interior angles of a polygon:</u></h3>
(n - 2)×180
Where n is the number of sides in the polygon
So,
<h3><u>Measure of interior angles in the figure:</u></h3>
= (n - 2) × 180
= (7 - 2) × 180
= 5 × 180
= 900

Using your approximate y-intercept on the line of best fit, your equation would be y=11/7x + 3.
We find the slope by choosing two points that are on the line:
(9, 18) is easy to spot; and (2, 7) is fairly easy to spot as well. The formula for slope is:
m=y₂-y₁/x₂-x₁
m=7-18/2-9 = -11/-7 = 11/7
Slope intercept form, y=mx+b, has the slope and the y-intercept. Plugging those in we have y=11/7x+3.
