First, we can raise each number to the second power by multipying it by itself. :)
1^2=1
4^2=16
9^2=81
16^2=256

These numbers are called "perfect squares" because their square roots are whole numbers, rather than decimals. For example, If you had a square with an area of 16, the side legnths of the square would be the whole (thus "perfect") number 4. For this reason, 16 (4^2) is considered a "perfect square" number. I hope that makes sense!! :)

A group of 2 adults and 4 children spent $38 on tickets to a museum. A group of 3 adults and 3 children spent $40.50 on tickets
Paraphin [41]

Answer:

Divide the 1st equation by 2

a + 2c = 19

Divide the 2nd equation by 3

a + c = 13.5

Subtract the 1st equation and the 2nd equation

c = 5.5

Substituting back into the 2nd equation will give:

a + 5.5 = 13.5

a = 8

Write the equation of the line that passes through the point (1,-1) and has a slope of -4
Phantasy [73]

Answer:

y= -4 x+3

Step-by-step explanation: A(1, -1)

the equation is y - y (A)=m*( x-x(A) )

y-(-1)=-4(x-1)

y+1=-4x+4

y= -4x+4-1

y=-4x+3

y=-4x+4-1

Which of the following are ordered pairs for the equation y = -4x + 5?
Firdavs [7]

(0, 5), (1, 1 ), ( - 1, 9 )

to test the points substitute the x-coordinate into the equation and if the value is equal to the y- coordinate then it is an ordered pair

(0, 5 ) → y = 0 + 5 = 5 ← ordered pair

(1, 1 ) → y = - 4 + 5 = 1 ← ordered pair

(- 1, 9 ) → y = 4 + 5 = 9 ← ordered pair

( - 1, - 1 ) → y = 4 + 5 = 9 ← not an ordered pair

( - 1, - 9 ) → y = 4 + 5 = 9 ← not an ordered pair

(1, - 1 ) → y = - 4 + 5 = 1 ← not an ordered pair

(- 1, 1 ) → y = 4 + 5 = 9 ← not an ordered pair
