Answer:
(-8, 2)
Step-by-step explanation:
set these equations equal to each other
1/2x + 6 = -3/4x -4
5/4 x = -10
x = -10x4/5 = -40/5 = -8
plug this x into one of the equations
y = 1/2 (-8) + 6
y = -4 + 6
y = 2
Answer/Step-by-step explanation:
Line segment AB consists of segment AC and segment CB.
AC = 7 cm
CB = 21 cm
The entire segment, AB = 21 + 7 = 28cm
The ratio of the segments partitions can be stated as follows:
Ratio of AC to CB = AC:CB = 7:21 = 1:3 = 
AC is ¼ of AB 
CB is ¾ of AB 
Answer:
34.9^2
Step-by-step explanation:
Well if one side is 4 cm then the square is 16cm^2.
The area of a circle is pi r^2.
So the radius is 2.
we plug 2 in.
pi 4
12.6/2
6.3
6.3 * 3 = 18.9cm^2
18.9 + 16 = 34.9
Answer:
The cost of each cavity filling was $ 134.60.
Step-by-step explanation:
Given that the total cost of Anfa's trip to the dentist was $ 628.35, and she paid a flat fee of $ 89.95 which included the checkup: cleaning and then had 4 cavities filled, each of which cost the same amount, to determine which shows the correct equation and value of x, the cost of each cavity filling, the following calculation must be performed:
(628.35 - 89.95) / 4 = X
538.4 / 4 = X
134.6 = X
Therefore, the cost of each cavity filling was $ 134.60.
Take a look at all 3 expressions: numbers, terms, and exponents.
4, 8, and 6 all have a GCF of 2.
y^5, y^3, and y^2 have a GCF of y^2.
Therefore, the GCF is 2y^2. Removing it gets you:
2y^2(2y^3 + 4y - 3)
