Use the graph to answer the question that follows. a coordinate plane with two intersecting lines is shown. one line has the equation x plus y equals 13 and there is shading above it. the other line has the equation 20 x plus 50 y equals 600 and passes through the ordered pairs of 10 comma 8, 20 comma lonnie has a gift card worth $600 for a local entertainment store. movies cost $20 each and newly released video games cost $50 each. in order to use the gift card, lonnie must purchase at least thirteen items. if lonnie wants to spend as much as possible on his gift card by purchasing the most items, which combination of movies and newly released video games is optimal?

false

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
