Complete the pairs of corresponding parts if ABD congruent to EFC.
Alchen [17]
Remember the notation..

When you have a triangle called ABD, the angles may be called in theses equivalent ways>

angle A is equivalent to ∠ DAB
angle B is equivalent to ∠ ABD
angle D is equivalen to ∠ BDA

Then given that the two triangles are congruent, you can say an

angle B = angle F = ∠ EFC

So the answer is the last option of the list.

Answer:

  • y = 7.5x + 20

Step-by-step explanation:

As per the graph, the y-intercept is 20 which is the initial amount.

Another marked point has coordinates (4, 50).

<u>The slope is:</u>

  • m = (50 - 20)/4 = 7.5

<u>The equation of the line is:</u>

You earn $15 per hour to babysit. After babysitting for 3 hours, you will earn $50. Write an equation in slope-intercept form to
Paha777 [63]

The equation  in slope-intercept form to represent the relationship between hours worked (x) and earnings in dollars (y) is y = $5 + $15x.

An equation in slope intercept form is usually written as: y = mx + b

Where:

  • m = slope
  • b = intercept

If I earn $15 per hour when  I babysit,  the amount I earn increases by $15 every hour. $15 is the slope of the equation. After 3 hours, the total amount I would earn is: $15 x 5 = $45.

In order to determine the intercept, subtract $45 from $50.

$50 - $45 = $5.
