Answer:

y = (2/9)(x + 1)² + 2

Step-by-step explanation:

y = a(x - (-1))² + 2

y = a(x + 1)² + 2

4 = a(2 + 1)² + 2

4 = 9a + 2

9a = 2

a = 2/9

y = (2/9)(x + 1)² + 2

Ramona's lemonade pitcher holds 32 ounces of lemonade, but it has a crack and leaks lemonade at a rate of 3 ounces per minute.
lapo4ka [179]

Answer:

Step-by-step explanation:

The rate of change of the situation is known as the slope:

Slope = Δy/Δx

Slope = y2-y1/x2-x1

From the graph, x2 = 10.5, x1 = 0. y2 = 32, y1 = 0

Slope = 32-0/10.5-0

Slope = 32/10.5

Slope = 3.047

Hence the rate of change is 3.047 ounces per minutes and the situation represents the slope of the graph.

Solve for x if the horizontal lines below are parallel.<br> fo
Bas_tet [7]

Answer:

x=82^{\circ}

Step-by-step explanation:

We can draw a perpendicular line through the two parallel lines to create a pentagon (there is an image attached in case you need to see where the line intersects the two parallel lines). Since the angle sum of a pentagon is 540^{\circ}, we can solve for x.

x+140+138+90+90 = 540 (Angle sum of pentagon is 540^{\circ})

x+458=540 (collect like-terms)

x=82^{\circ}

Hope this helps :)
