Answer:
x = -1, y = 4.
Step-by-step explanation:
y = -x + 3
y = x + 5 Adding these 2 equation eliminates x:
2y = 0 + 8
y = 8/2 = 4.
Substituting for x in the first equation:
4 = -x + 3
4-3 = -x
1 = -x
x = -1.
Answer:
The denominator is all real numbers except 0.
Step-by-step explanation:
In the function f(x) = 1/x, x appears in the denominator. A denominator cannot be zero since division by zero is undefined.
To find what values of x must be excluded from the domain, set the denominator equal to zero, and solve for x.
x = 0
The denominator is all real numbers except 0.
Answer:
ok for one if you dont know the answer or u need a picture dont use the answering box to say that and for two what i said before so in conculdsion dont try gettig points by not putting an answer its pretty anoying
and the answer is JG OR B on edgenuety
Step-by-step explanation:
Answer:
B.
Step-by-step explanation:
Step 1: Cross-multiply
x² + 2x = 4x²
Step 2: Isolate <em>x</em>'s
2x = 3x²
0 = 3x² - 2x
Step 3: Factor
x(3x - 2) = 0
Step 4: Find roots
x = 0, x = 2/3
Step 5: Double check answers.
When you do so, you should see that only x = 0 works. And we have our answer!
