DedPeter [7]2 years ago

Answer:

  1. x - 5y = -5; x -5y = 35
  2. there are no solutions, the lines are parallel so do not intersect

Step-by-step explanation:

<h3>1.</h3>

We judge the x-intercept to be about 5 times as far from the origin as the y-intercept is. If we take the y-intercept of the blue line to be +1, then the equation of that line can be x -5y = -5. The y-intercept of the black line appears to be about 7 times as far from the origin as for the blue line, so the constant will be multiplied by -7: x -5y = 35.

The two equations in the system of equations could be ...

  • x -5y = -5
  • x -5y = 35

__

<h3>2.</h3>

We have assumed the two lines are parallel, so they will not intersect. A point of intersection would be a solution to the system. The system of equations will have no solutions.

A road is inclined at an angle of 5°. After
Scorpion4ik [409]

Answer:

464 feet

Step-by-step explanation:

<em>The Sine of the angle of inclination gives the increase in altitude.</em>

<em>This is because the Sine of an angle is equal to the Opposite side divided by the Hypotenuse side. i.e</em>

Sin Ф = Opposite  ÷ Hypotenuse

Sin 5° = O ÷ 5328

0·08716 = O ÷ 5328

<em>Make </em>O<em> the subject and multiply every fraction by </em>5328

(0·08716/1 × 5328)= (O/5328 × 5328)

464·388 = O

∴ The increase in altitude is 464·388 feet

<em>This is supposed to be to the nearest foot so we round off</em>

464·388 becomes 464 feet
