Answer: (-3,1)

Step-by-step explanation:

We know that a reflection is a transformation in which each point of a figure maps at an equal distance on the opposite side across a given line of reflection.

From the given graph the coordinates of point t = (-3,-1)

Since it is reflected across the x-axis , then its x coordinate remains same, but the polarity of y coordinate changes.

Thus, the coordinate of its reflection image = (-3,1)

On a certain hot summers day, 648 people use the public swimming pool. The daily prices are $1.50 for children and $2.25 for adu

ehidna [41]

Answer:

252 children and 395 adults

Step-by-step explanation:

Make a linear system of equations, where x represents the number of children and y represents the number of adults

x+y=648

1.50x+2.25y=1269

solve using substitution, so y=648-x,

then substitute this into the second equation, so you get 1.50x+2.25(648-x)=1269,

solve for x and you will get x equals the 252

then substitute this into the first equation, so you get 252+y=648

solve and you will get y=395

Fiona is serving iced tea and lemonade at a picnic. She has only 44 cups in which to serve the drinks. If x represents the numbe

masha68 [24]

The number of glasses is restricted to 44 cups. So the number of iced tea cups and the number of lemonade cups that she can serve is, maximum, 44. Then, if you call x the number of glasses of iced tea and call y the number of glasses of lemonade, you have that the total number of glasses (cups) is x + y. And <span>the equation that represents the number of glasses that she cacn serve is x + y = 44. You can place it in other equivalent ways, for example, solve for y: y = 44 - x. Those two equations are valid answers because they represent the same equation.</span>

Answer:

46872

4687200

46872000

468720000

Step-by-step explanation:

say x is "?"

x ÷ 10000 = 4.6872

multiply 10000 into 4.6872 = 46872

x ÷ 10000 = 468.72

Multiply 10000 into 468.72 = 4687200

For each "0" you would move a decimal to your right when multiplying and move it to your left when dividing
