The first graph is correct.
Although we cannot see the y-intercept, you can see a positive slope and that the y-intercept would be negative. The second graph has a negative slope, which would not work. And the 3rd graph has an intercept of -1, which is not correct.
Answer:
−y−1=3
Step-by-step explanation:
Which equation can be used to find the solution of (1/4)^y+1=64?
This can be solved by power of indices
(1/4)^(y+1)=64
(4^-1)^(y + 1)= 4^3
Note
(x^a)^b = x^ab
Hence:
4^(-1)(y + 1)= 4^3
4^-y - 1 = 4^3
Divide both sides by 4
−y−1=3
Hence, the equation that can be used to find the solution of (1/4)^y+1=64 is
−y−1=3
Answer:
2.40 × 10²
Step-by-step explanation:
Data provided in the question:
we have to convert 820,000 Btu/h to kW
Now,
1 kW = 3412.142 Btu/h
or we can say
1 Btu/h = 0.00029307107 kW
Therefore,
820,000 Btu/hr in kW will be
= 820,000 × 0.00029307107 =
or
= 240.3182774
or
= 2.40 × 10²
Hence,
according to the question, X will be 2.4 and the term in the power of 10 is 2
Answer:
Step-by-step explanation:
If there are 90 students and the ratio of boys to girls is 3:2, that means 3x+2x=90
Combine like terms: 5x=90
x=18
2x (girls)=36
3x (boys)=54
1/3 of the boys scored full marks, so 54/3=18 boys scored full marks
The number of girls who scored full marks is half of the number who did not score full marks means that 1/3 of the girls scored full marks. 36/3=12, so 12 girls scored full marks.
(I don't know what the question is sorry if it's incorrect but there's not enough information)
Hope this helps!
i think its
6x4-1 that should be the awnser
