Write an equation that represents the line

Mathematics
1 answer:
madam [21]3 years ago
4 0

Answer:

y = -2x - 3

Step-by-step explanation:

First, find slope (m) of the line using two points (0, -3) and (1, -5):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-5 -(-3)}{1 - 0} = \frac{-2}{1} = -2

The line intercepts the y-axis at y = -3. Therefore the y-intercept (b) of the line = -3.

To write the equation that represents the line, substitute m = -2, and b = -3 into y = mx + b.

Thus:

y = -2x + (-3)

y = -2x - 3

Work out the balance for £5000 invested for 5 years at 7% per annum
zvonat [6]
Given:
Principal : 5,000
Interest rate : 7% per annum
Term : 5 years

Simple interest is computed by multiplying the principal, the interest rate, and the term.

Simple Interest = Principal * interest rate * term

S.I. = 5,000 * 7% * 5years
S.I. = 350 * 5 years
S.I. = 1,750

An investment of 5,000 will earn a total of 1,750 within 5 years at 7% per annum.

Pls!!<br> f(x)=√x+2 and g(x)=9x−4<br> f(g(x))=<br><br> f(g(3))=<br> show work pls thank uu
Monica [59]

Answer:

  • Find f(g(x)) by substituting the entire g(x) function for x in f(x)
  • f(x)=\sqrt{x} +2\\f(g(x))=\sqrt{(9x-4)} +2 that's the answer
  • Then f(g(3)) is just putting in place of x in our new equation
  • f(g(x))=\sqrt{(9x-4)} +2\\f(g(3))=\sqrt{(9(3)-4)} +2\\f(g(3))=\sqrt{(27-4)} +2\\f(g(3))=\sqrt{(23)} +2\\f(g(3))=6.80  rounded to 2 decimal places

Two straight lengths of wire are placed on the ground, forming vertical angles. If the measure
nikdorinn [45]

Answer:  72°, 108°, 108°

<u>Step-by-step explanation:</u>

Vertical angles are congruent (equal) so if one angle is 72° then its vertical angle is also 72°.

A vertical angle and its adjacent angle form a 180° angle, so the other two angles are each 180° - 72° = 108°
