Number one is D
number 2 is A
Answer:
There is one solution and that answer is mixed number form 1 5/7 or exact form 12/7
Step-by-step explanation:
Answer:
x,y = 13/3, -10/3
Step-by-step explanation:
8x+8y=8
8x+2y=28 Subtract eq1 by eq 2
6y=-20
y=-20/6 y = -10/3
8x - 80/3=8
8x=34 2/3
x=4 1/3
x=13/3
Hope this helps plz hit the crown :D
The given ordered pair is not the solution to the equation
Step-by-step explanation:
In order to find if an ordered pair is a solution to the equation or not, we plug in the values of x and y in the equation. If the equation is true for the point then the ordered pair is the solution to the equation.
Given equation is:

Answer:
a= -5
Explanation:
Rewrite the equation to be: 3^a=3^-1 / 3^4
Multiply by adding exponents :))
which would then be 3^a = 3^-5
Then, since the bases are the same then the a would equal negative (-) 5. :))
Hope this helps :)) Plz mark brainlest :))
