Answer:
You can say there is no solution for a system of linear equation when the graphs are PARALLEL to each other.
ONE solution: when both lines intersect at one point
INFINITE solution: when the line goes on forever
NO solution: is when the lines are parallel to each other.
There are 200 students in the group.
To find this, you divide 70 by 0.35 (35%). This will give you 200. To check this, multiply 200 by 0.35 and you will get 70. Thus making 200 the answer.
I hope this helps!
Answer:
growth
Step-by-step explanation:
the value under ^x is more than 1
7/4 >1
So, we have exponential growth
Answer:
-y^2 - 10 y - x^72 + -1
Step-by-step explanation:
Simplify the following:
-y^2 - 3 y - 5 - (x^36)^2 - 7 y + 4
Multiply exponents. (x^36)^2 = x^(36×2):
-y^2 - 3 y - 5 - x^(36×2) - 7 y + 4
36×2 = 72:
-y^2 - 3 y - 5 - x^72 - 7 y + 4
Grouping like terms, -y^2 - 3 y - 5 - x^72 - 7 y + 4 = -y^2 + (-3 y - 7 y) - x^72 + (4 - 5):
-y^2 + (-3 y - 7 y) - x^72 + (4 - 5)
-3 y - 7 y = -10 y:
-y^2 + -10 y - x^72 + (4 - 5)
4 - 5 = -1:
Answer: -y^2 - 10 y - x^72 + -1
