Anything to the power of 0 is one.
Therefore we have:
(1)(y^-7z)
Which simplifies to:
y^-7z
Answer:
The equation which represents the function is given by,
x = 3y .
Step-by-step explanation:
The direct variation function contains the points, (-9, -3) and (-12, -4).
Here,
= 3
So, the equation which represents the function is given by,
x = 3y .
Answer:
Step-by-step explanation:
I think b but i might be wrong
10a + 8b = 230
a + b = (2 + 2 + 13 + 10)...a + b = 27 (this is the number of gifts to buy)
a = 27 - b
10(27 - b) + 8b = 230
270 - 10b + 8b = 230
-10b + 8b = 230 - 270
-2b = -40
b = -40/-2
b = 20 <=== she bought 20 eight dollar gifts
a = 27 - b
a = 27 - 20
a = 7 <=== she bought 7 ten dollar gifts
