Answer:
The correct answer is B
Step-by-step explanation:
2(x-1) + 5x = x-8
Firstly, break all the brackets and you would got:
2x - 2 + 5x = x - 8
Put x into 1 side,
2x + 5x - x = -8 + 2
6x = -6
Divide both side by 6,
6x / 6 = -6/6
x = -1
The correct answer is B
Hope this help you :3
Y = x^2 - 16x + 17
-16/2 = (-8)
(-8)^2 = 64
Add 64 and subtract 64
y = x^2 - 16x + 64 + 17 - 64
y = (x - 8)^2 - 47
A rational number is any number that can be express as a ratio integers whose decimal value is finite or at some point repeats with out end. (Any whole number <span> positive or negative- can be expressed as an improper fraction.</span>
Answer:
The volume of the new prism is three times the volume of the old prism
Step-by-step explanation:
To carry out this problem we have to invent 3 variables that represent length, width and height
w = width
h = height
l = length = 19cm
Now we have to do the equation that represents the calculation of the volume of the prism
v = w * h * l
v = w * h * 19
v = 19hw
assuming the length is tripled
v = w * h * 3l
v = w * h * 3 * 19
v = 57wh
To know the volume of the new prism with respect to the previous one, we simply divide the volume of the new prism by the previous one.
57hw / 19hw = 3
The volume of the new prism is three times the volume of the old prism
The probability of not spinning an even number should be two out of three or 2/3. because there is only 1 even number (2).
