3 0

Answer:

y = 70 and x = 20

Step-by-step explanation:

180 - 40 = 140

140/2 = 70

70 + 90 = 160

180 - 160 = 20

What is the algebraic rule?? And how do you find out what algebraic rule on a graph is (x,y)to (x,y+10)??? I know how to find ba
Arlecino [84]

Answer:

  (x, y) ⇒ (-x, y)

Step-by-step explanation:

When you're looking for a rule that transforms one figure to the other, the first step is to look at the figures. You want to identify their orientation (order of vertices) and the relative locations of corresponding vertices.

Here, vertices VWX are in <em>clockwise</em> order. The corresponding vertices V'W'X' are in <em>counterclockwise</em> order. For that to happen, there must be a reflection involved.

The y-axis goes through the midpoints of VV', WW' and XX'. This means the y-axis is the line of reflection. The coordinates of V'W'X' have the same y-values as their originals, but their x-values have changed sign.

The algebraic rule for these two figures is ...

  (x, y) ⇒ (-x, y) . . . . . . reflection over y-axis; sign of x changes

__

<em>Additional comment</em>

No rotation is involved here.

The rule (x, y) ⇒ (x, y+10) means the y-coordinate has had 10 added to it. That causes a translation upward by 10 units. This <em>is</em> the algebraic rule.

Bethany is paid time-and-a-half for each hour she works above her normal 40 hours each week. Last week, Bethany worked 44 hours
scoray [572]

Answer : $18.75

Bethany is paid time-and-a-half for each hour she works above her normal 40 hours each week. Last week, Bethany worked 44 hours and her gross pay was $575.

Total hours worked = 44 hours

Normal 40 hours + 4 hours extra

Let x be the amount earned for 1 hour for regular 40 hours

1.5x be the amount earned for extra hours

40 (amount earned for normal hours ) + 4(amount for extra hours ) = gross pay

40x + 4(1.5x) = 575

40x + 6x = 575

46 x = 575

Now divide both sides by 46

x = 12.5

1.5x is the amount earned for extra hours

1.5 * 12.5 = 18.75

Bethany earn for each hour of overtime she worked is $18.75
