Answer
Find out the how many birds were at the shelter on Wednesday .
To prove
let us assume that the number of birds be = x
let us assume that the number of cats be = y
As given
An animal shelter spends $3.00 per day to care for each bird and $7.00 per day to care for each cat.
Alexandra noticed that the shelter spent $174.00 caring for birds and cats on Wednesday.
than the equation becomes
3x + 7y = 174
As given
Alexandra found a record showing that there were a total of 34 birds and cats on Wednesday.
than the equation becomes
x + y = 34
Than the two equation are
3x + 7y = 174
and x + y = 34
multiply 3 by x + y = 34 and subracted from 3x + 7y = 174
3x - 3x + 7y - 3y = 174 - 102
4y = 72
y = 18
put in the equation x + y = 34
18 + x = 34
x = 34 - 18
x = 16
The number of birds at the shelter on wednesday is 16 .
Answer:
-5x + y = -27
Step-by-step explanation:
Equation: y+8 = -5(x+3)
Standard form is (ax + by = c)
We have to get x and y and their coefficients over to the left side of the equation, and all the single numbers to the right side.
y + 8 = -5 (x + 3)
y + 8 = -5x -15
y = -5x - 27
THE ANSWER IS :
-5x + y = -27
Answer:x=4
Step-by-step explanation:
X can be any real number
As long as it is to the power of 0, it will equal one. And because 6^0 = 1, 1^x can be any positive number, and it will still give you one.
As stated by WojtekR, even negative numbers can get 1
x = - 5
(6^0)^-5 = 1^-5 = 1/1 = 1
