To find the slope between two coordinates, you use the formula:
m = y2 - y1/x2 - x1
If coordinate A is (-2, 5) and coordinate B is (3, -4), then:
y2 = -4
y1 = 5
x2 = 3
x1 = -2
So, just substitute the points into the formula.
m = -4 - 5/3 - (-2)
m = -9/5
The slope of the line is -9/5.
Answer: 7
Step-by-step explanation:
As tangents drawn from a common external point to a circle are congruent,
- 8x - 7 = 6x + 7
- 2x - 7 = 7 [subtract 2x from both sides]
- 2x = 14 [add 7 to both sides]
- x = 7 [divide both sides by 2]
Answer:
D. angle 7 and angle 5.
Step-by-step explanation:
It is actually option 'D.' This is because angle 7 and angle 5 are vertical angles; vertical angles are always congruent.
513.15 is the answer to that question
Answer:
<h2>5x^2 - 11</h2>
Step-by-step explanation:
We got to add these together so
2x^2-8x-9+3x^2+8x-2
the 2x^2 and 3x^2 add to 5x^2
the 8x and -8x cancel each other out
the -9 and -2 add to -11
so..
5x^2 - 11
I hope this helped :)
