B)

x-intercepts: (1,0) and (3,0), y-intercept: (0,–3), vertex: (2,1)

C)

x-intercepts: (–1,0) and (–3,0), y-intercept: (0,–3), vertex: (2,–1)

D)

x-intercepts: (1,0) and (3,0), y-intercept: (0,–3), vertex: (–1,2)

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

there is no question content here, but you for the free points! : d

the answer is a.
