All the points in the doubly-shaded area are in the solution set.
To have infinite solutions, they have to be th esame line
match waht we do know
bx-6y=18
the coefient of y is -6
other one is
2x-3y=9
-3 times 2=-6
times 2nd equation by 2
4x-6y=18
bx-6y=18
b=4
Answer:
log₁.₅3 or 2.70951
Step-by-step explanation:
- 3^(2x) - 2^(x + 1) * 3^x - 3*2^(2x) = 0
- 3^(2x)- 2*2^x*3^x + 2^(2x)- 4*2^(2x)=0
- (3^x-2^x)^2 - (2*2^x)^2=0
- (3^x-2^x+2*2^x)(3^x - 2^x - 2*2^x)=0
- (3^x+2^x)(3^x- 3*2^x)=0
- 3^x+2^x>0 for any value of x
- 3^x- 3*2^x=0
- 3^x= 3*2^x
- 3^x/2^x=3
- 1.5^x=3
- x= log₁.₅ 3 = 2.70951
The answer is B because it isn’t asking for both zeros, it’s only asking for one and there is no 1 and 0, so the only other zero is between -4 and -3.
I think b but I’m not completely sure
