(-2.3, 4.7) & (-1.5, 6.2)
X1. Y1. X2. Y2
M= <u> Y2 - Y1 </u> = <u>6.2 - 4.7 </u>
X2 - X1 -1.5 - (-2.3)
M= <u>6.2 - 4.7 </u> = <u>10.7</u> = 13.375 = 13.4
<u> </u>-1.5 + 2.3 0.8
The answer is 11.
Hope this helps!
Answer:
========================================================
Work Shown:
The answer has been confirmed with WolframAlpha which is basically a calculator app, but does a ton more than any average calculator.
The CAS (computer algebra system) in the app GeoGebra is another tool I use all the time.
Yet another way to confirm the answer is to graph the original expression and the answer as separate functions. You should find they produce the <u>exact</u> same curve. One curve perfectly overlaps the other. This visually verifies the two expressions are the same thing, just written a different way of course.
Let me know if you have any questions about any step. The basic idea I did was to pull out the GCF and then combine like terms.
Answer:
x=3
Step-by-step explanation:
The equation is x² + 5x = 24, so 3² +15 would be the perfect match. This is because 9+15=24.
Answer:
x=1
Step-by-step explanation:
Substitute the y equation for the variable y in the second question
3x +2(4x-2)=7
3x+8x-4=7
11x-4=7
11x=11
x=1
