Answer:
x=12
Step-by-step explanation:
This is a right triangle, so the Pythagorean theorem can be used. The Pythagorean theorem states that
where C is the hypotenuse and a and b are legs. In this question, we are given a and C. So, plugin 13 for C and 5 for a and solve for b. Once you rearrange the equation you get,
. Next, solve what is under the root to get,
. Finally, square root 144 for the final answer b=12.
Factor the equation:
(x-6)(x+1)
Check:
-6+1=-5
-6*1=-6
Use the zero product property
x-6=0
x=6
x+1=0
x=-1
Final answer: x=-1, x=6
Answer:
y = 5 -2/3 ( x-9)
Step-by-step explanation:
point slope form
y = y0 + m(x - x0).
m is the slope
m = (y2-y1)/(x2-x1)
( 7-5)/(6-9)
2/-3
=-2/3
The slope is -2/3
Using the point (9,5)
y = 5 -2/3 ( x-9)

Answer:
1. 80%
2. 12.5%
3. 10%
Step-by-step explanation:
The figure contains 100 equal squares, so the number of squares shaded is equal to the percentage of squares shaded.
