HELP ASAP

Mathematics
1 answer:
Natalija [7]3 years ago
5 0

Answer:

The equation of the function: y = mx + b

  • m = slope = (y₂ - y₁)/(x₂ - x₁) = [5 - (-3)]/(4 - 0) = (5 + 3)/4 = 8/4 = 2
  • b = y-intercept = -3

Therefore, the equation is <u>f(x) = 2x - 3</u>

When x = 0, f(x) = 2(0) - 3 = <u>-3</u>

When x increases by 1, f(x) increases by <u>2</u> (slope = the rate of change)

R is inversely proportional to A.
hjlf

Here are the answer: a) R = 3.6 and b) A = 2

Step-by-step explanation:

Given,

R is inversely proportional to A.

R ∝ \frac{1}{A}

so, R = \frac{k}{A}  -------eq 1 where k is any constant

To find the values of a) R when A = 5 and

b) Value of A when R = 9

Now,

Putting R = 12 and A = 1.5 in eq 1 we get,

12 = \frac{k}{1.5}

or, k = 12×1.5 = 18

From eq 1 we get,

R = \frac{18}{A} --------- eq 2

Now,

a) Putting A= 5 in eq 2 we get,

R = \frac{18}{5} = 3.6

b)  Putting R = 9 in eq 2 we get

R = \frac{18}{A}

or, A = \frac{18}{9} = 2
