Domain is th enumbers you can use and not cause conflict (like dividing by 0 or something)
actually, the domain is all real numbers
there is no real value of x that will make us divide by 0 or take the square root of a negative number
domain is all real numbers
Equation #1:
|2x - 3| = 17
The first solution is
2x - 3 = 17
2x = 17 + 3 = 20
x = 10
The second solution is
3 - 2x = 17
-2x = 17 - 3 = 14
x = -7
The solutions are x = 10 or x = -7.
Equation #2:
|5x + 3| = 12
The only solution is
5x + 3 = 12
5x = 12 - 3 = 9
x = 9/5
Let us examine the given answers.
a. Equation #1 and #2 have the same number of solutions.
FALSE
b. Equation @1 has more solutions than Equation #2.
TRUE
c. Equation #1 has fewer solutions than equation #2.
FALSE
d. None of the statements a,b, or c apply.
FALSE
Answer: b.
Answer:
10
Step-by-step explanation:
The arc length of the semicircle is
- a+(a+1)+(a+2)+(a+3)+(a+4)=5a+10
As x = 42, this means a+4 is 42/180 of the arc length of the circle, 5a+10.
So,
- (42/180)(5a+10)=a+4
- 42(5a+10)=180(a+4) [multiply both sides by 180]
- 210a+420=180a+720 [distributive property]
- 30a+420=720 [subtract 180a from both sides]
- 30a=300 [subtract 420 from both sides]
- a=10 [divide both sides by 30]
