is it 42 or 4 and 2 separate
answer is (-7,2)
y = -x -5
y= x+9
Both equations have y on the left hand side
So we equate both equations
We replace -x-5 for y in the second equation
-x -5 = x+9
Subtract x on both sides
-2x -5 = 9
Now add 5 on both sides
-2x = 14
Divide by -2 from both sides
x = -7
Now plug in -7 for x in the first equation
y = -x -5
y = -(-7) -5= 7-5 = 2
So answer is (-7,2)
Answer:

Answer:
6
Step-by-step explanation:
a^2 + 8^2 = 10^2
a^2 + 64 = 100
a^2 = 36
sq root of a = sq root of 36
a = 6
Answer:
10
Step-by-step explanation:
1 tenth: 1/10
1 hundredth: 1/100
1/10 = X × 1/100
X = 100/10
X = 10
