IRISSAK [1]3 years ago
8 0

Answer:

The x-intercept is 8/7.

Step-by-step explanation:

There is only one x-intercept because the equation is linear. And you don't need the quadratic formula to find the x-intercepts at all. Hope this helps!!

Find the 61st term of the following arithmetic sentence
Leno4ka [110]

Answer:

The 61st term would be 495

Step-by-step explanation:

In order to find the 61st term, you need to find the rule for the sequence. You'll notice that the numbers are going up by 8. Since there is no 0th term, the first term would be 8 more than the base.

15 - 8 = 7

Therefore the base is 7. As a result, you can model the sequence as:

An = 8n + 7

In which n is the number in the sequence. Now knowing this, we can plug in 61 and get the answer.

An = 8n + 7

An = 8(61) + 7

An = 488 + 7

An = 495

Derive the equation of the parabola with a focus at (−5, 5) and a directrix of y = −1. (2 points)
love history [14]
The focus is above the directrix, so the parabola opens upward—its vertical scale factor is positive (+1/12). The line of symmetry is x=-5, so the vertex form of the equation will have the factor (x -(-5))² = (x+5)². The choice that meets both these requirements is
  D. f(x) = (1/12)(x + 5)² + 2
