Answer:
This horizontal line is written as y = 9
Step-by-step explanation:
All horizontal lines are written in the form of y = (a number). In this case, we know that the y number must be in the ordered pair given. Therefore, we simply write the equation as y = that number.
y = 9
The value for x is already given; x = -2
Substitute -2 in for x in the second equation.
y = 2/3(-2) + 3
y = -4/3 + 3
y = 5/3
The final answer is (-2, 5/3).
Answer:
Step-by-step explanation:
w + g = 52
w = 4g - 3
(4g - 3) + g = 52
5g - 3 = 52
5g = 52 + 3
5g = 55
g = 55/5
g = 11....there are 11 green marbles
w + g = 52
w + 11 = 52
w = 52 - 11
w = 41 <=== there are 41 white marbles
Okay. fist off don't think of them as 5 units each, but 1. so if you were to put it on graphing paper and box squares each time. you would be able to get 8 in for both sides to make a square. Area then would be 1600ft squared because 8 ×5 is 40 and 40×40 is 1600. then you calculate how many squares you used. 8×8=64. and 80-64=16 so 16 pieces are left over. then 9×9 (increasing the square) is 81. so 17 pieces to increase it.
Answer:the 1st one is x=√66 or x=−√66 2nd is x=0 or x=8
