Answer:
a = -1
Step-by-step explanation:
first you make the x 0 and the y 0
0 = (0 - 1)^2 + a
0 = (-1)^2 + a
then you deal with the exponent
0 = 1 + a
lastly you subtract everything by 1
-1 = a
a = -1
that is your answer
3x-12y = 5
-x+3y = 9
First step is to make the coefficient of either x or y same.
3x-12y = 5
(-x+3y = 9)3
3x-12y = 5
-3x+9y = 27
-4y = 32
y = -8
Answer:
it is 666 the sign of my friend and all around cool guy
plz give brainliest
Step-by-step explanation:
Hello,
Please, see the attached file.
Thanks.
#6
Yes
Direct variation because Time increases cupcakes increases and vice versa
#B
Constant of proportionality represents the amount of time required per cupcakes
#7
Yes we can find it
We have to check the x and y values of the ordered pairs (x,y)
If y is decreasing with respect to increase in x then it's inverse variation
