F(x)=25-x^2
g(x)=x+5
f/g(x)=(25-x^2)/(x+5)
f(x) is in binomial form so 25-x^2 can also be written as (5-x)(5+x)
so
f/g(x)=(5-x)(5+x)/(x+5)
f/g(x)=5-x
We see two parallel lines crossed by a transversal.
The two labelled angles are alternate interior angles, hence they are equal.
The equality allows us to equate the two expressions and hence solve for x.
8x-3=5x+42
transpose terms
8x-5x=42+3
solve for x
3x=45
so x=45/3=15.
This means 5x+42=5*15+42=75+42=117 degrees.
Well, I don't know if the following work is exactly what you want but here it goes:
first:23
second: 23-3=20
third: 20-3=17
fourth:17-3=14
fifth: 14-3=11
sixth: 11-3=8
Hope thats what you wanted if not Ill do my best to figure out a different solution. Just comment or private message me For questions. :0
Answer:
Angle ABD is 16 degrees and Angle DBC is 74 degrees
Step-by-step explanation:
Question 6. x+9+11x-3=90. 12x+6=90 -6 on both sides and 12x=84 divide each side by 12 and x= 7 angle ABD is x+9 so 7 +9= 16. Angle measure of ABD is 16 degrees. Measure of angle DBC is 11x -3 so 11 times 7=77. 77-3= 74. So the measure of angle DBC is 74 degrees and this answer is right because they both add up to be 90 degrees. Hope this helped! :)
Answer:
1/2
Step-by-step explanation:
Or, 8(x-3)+7= 2x(4-17)
Or, 8x-24+7=2x(-13)
Or, 8x-17= -26x
Or, 34x=17
x=1/2
