John will be x in 7 years. How old was he last year? A: x + 7
B: 1 - x - 7
C: x + 8
D: x - 8

Answers

Right now, he is 7 less than he will be in 7 years, and 1 more than he was last year.

'x' is 7 more than he is right now, and 8 more than he was last year.

If 'x' is 8 more than he was last year, then he was  (x - 8) last year.

That's Choice-'D'.
D is the answer, because seven minus X is his age this year and a year before that is last year. So the answer is X-8

Answer:

A: The x-intercept is x = -5 and the graph approaches a vertical asymptote at x = -6

Step-by-step explanation:

The diagram shows translated to the left graph of the logarithmic function.

This graph intersects the x-axis at point x = -5, hence the x-intercept is at x = -5.

This graph approaches to the vertical line. The line passes through the point (-6,0), so the equation of this vertical line is x = -6.

Therefore, correct option is A: The x-intercept is x = -5 and the graph approaches a vertical asymptote at x = -6

Use formula p=2l+2w find the perimeter of a rectangle with a length 8.3 ft and width of 15.8 ft

Answers

Answer:

p = 48.2

Step-by-step explanation:

p = 2L + 2w

p = 2(8.3) + 2(15.8)

p = 16.6 + 31.6

p = 48.2

Answer:

P = 48.2 ft

Step-by-step explanation:

P =2l+2w

Given: l  = 8.3 ft and w = 15.8 ft

Plug in

P =2(8.3) + 2(15.8)

P = 16.6 + 31.6

P = 48.2 ft
