Step-by-step explanation:
When f(x) = f(x - 4), 3x² = 3(x - 4)².
=> x² = (x - 4)², x = -(x - 4), 2x = 4, x = 2.
The x-value is 2.
The question is asking for the intersection of the line and the parabola. Where does the blue parabola and the red line meet? <em>at (-1, -3) and (3, 5)</em>
Answer: B) x = -1 , x = 3
Answer:
an = 12 -7(n-1)
an = 19-7n
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
an = a1 +d(n-1) where a1 is the first term and d is the common difference
a1 =12
We find d by taking the second term and subtracting the first term
d = 5-12
d = -7
an = 12 -7(n-1)
We can simplify this
an = 12 -7n+7
an = 19-7n
Answer:
59 and 79
Step-by-step explanation:
59+79=138
59 is 20 less than 79 so it works
