Answer:
C) y = -8
Step-by-step explanation:
Answers A and B are not the answer because when the equation is x= this means it’s undefined.
D can be it because the zero in y= 0 refers to the y-intercept or when the line crosses through the y-axis.
So in the question, the coordinate (0,8) has a abscissa of 0 so that means the coordinate is the y-axis.
So y = -8 is the answer because -8 refers to the y-intercept and our questions says that the equation has a y-intercept of -8.
Just keep doing what you did in 1. I'll show you how easy it is.
2.
a) g(9) = 9 - 5 / 2 = 4 / 2 = 2.
b) g(0) = 0 - 5 / 2 = 5 / 2 = 2 1 / 2.
c) g(3) = 3 - 5 / 2 = 2 / 2 = 1.
d) g(17) = 17 - 5 / 2 = 12 / 2 = 6.
3.
a) f(3) = 3^2 - 4 = 9 - 5 = 4.
b) f(-4) = -4^2 - 4 = 16 - 4 = 12.
c) f(0) = 0^2 - 4 = 0 - 4 = -4.
d) f(-2) = -2^2 - 4 = 4 - 4 = 0.
4.
a) f(10) = 10 / 2 - 6 = 5 - 6 = -1; -1 is the solution.
5.
a) I'll test one after another.
1. f(0) = 2(0) - 3 = 0 - 3 = -3 > g(0) = 3(0) / 2 + 1 = 0 + 1 = 1; this is incorrect.
2. f(2) = 2(2) - 3 = 4 - 3 = 1 = g(2) = 3(2) / 2 + 1 = 6 / 2 + 1 = 3 + 1 = 4; this is incorrect.
3. f(8) = 2(8) - 3 = 16 - 3 = 13 = g(8) = 3(8) / 2 + 1 = 24 / 2 + 1 = 12 + 1 = 13; this is correct.
4. g(4) = 3(4) / 2 + 1 = 12 / 2 + 1 = 6 + 1 = 7 < f(4) = 2(4) - 3 = 8 - 3 = 5; this is incorrect.
Hope this helps :)
Answer:
The percent charge of Kanna's DS is 50%
Step-by-step explanation:
we know that
A Nintendo DS takes 4 hours to charge fully (100%)
4 hours is the same that 240 minutes
using proportion
Find out what percentage represent 108 minutes
Remember that
Kanna Kamui charge her DS from 5%
so
therefore
The percent charge of Kanna's DS is 50%

Work out the total change:
76 - 46 = 30
Divide this by the number of days:
30/5 = 6
As the temperature decreased, it would have a minus value in front of it
Thus, the answer is option B
Have A Nice Day ❤

Answer:
30%
Step-by-step explanation:
27 over 90 is equal to 0.3 in decimal form, turn that into percentage by multiplying by 100, and you get 30%
