1/3(2x-8) =4
A. 2
B. 6
C.10
D. 10/3
Answer:
x = 10
Step-by-step explanation:
1/3(2x-8) =4
Multiply each side by 2
3*1/3(2x-8) =4*3
2x-8 = 12
Add 8 to each side
2x = 12+8
2x= 20
Divide by 4
2x/2 =20/2
x= 10
Answer:
x=10
Step-by-step explanation:
2x-8=12
2x=12+8
2x=20 divide by 2
x=10

f(x) = sqrt(x^2 + 3) ; g(x) = sqrt(X-2)
Find f(g(x))
Answer:
F(x) = sqrt(x^2 + 3) ; g(x) = sqrt(X-2)
f(g(x))= √[{√(x-2)²+3}]
=√[{x-2+3}]

What is the probability of choosing a number from 1 to 10 that is greater than 5 or even?
Answer:
3/10 or 30%
Step-by-step explanation:
The longest, yet easiest way to do this is to find all possible numbers that fit this scenario
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Even Numbers: 2, 4, 6, 8, 10
Greater Than 5: 5, 6, 7, 8, 9, 10
Now find common numbers in both categories
6,8, and 10
meaning the probability is 3/10 or 30%

Each expression with the appropiate property:
Answer:
It is the Commutative property.
Step-by-step explanation: The word commutative comes from the word "move around" in this case all the numbers did was switch positions. Another example; 2+3=3+2 that is commutative property because the numbers were moved. Much similar to your problem

Write an absolute value expression to represent the distance between -2 and 4 on an number line. Then evaluate the expression.
Answer:
|-2| + |4|
= 6
Step-by-step explanation:
The absolute value is the distance from zero on the number line, so you would use the expression above to get the answer, 6
Hope this helps!
can someone please help
Explanation:
The rule [tex](x,y) \to (-x,y)[/tex] has us flip the sign of the x coordinate from positive to negative (or vice versa). This applies a reflection over the y axis. For example, the point (5,6) moves to (-5,6).
Currently this shape is in quadrant 1. The quadrants start in the top right corner, and you move counterclockwise going to quadrants 2,3, and 4. Quadrant 2 is to the left of quadrant 1, and this is where all of the points end up after applying a reflection over the y axis.
At the beginning of the day the stock market goes down 50 1/2 points and stays at this level for most of the day. At the end of the day the stock market goes up 80 1/4 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the day?
Answer:
The change for the day is 29 3/4Step-by-step explanation:
In this problem, we are expected to calculate the change in the price of a particular stock
Given that the days high is 80 1/4
and also that the days low is 50 1/2
we can calculate the change by subtracting the days low from the days high
i.e 80 1/4- 50 1/2= 321/4-101/2= (321-202)/4= 119/4 = 29 3/4
hence the change for the day is 29 3/4
Also we can calculate the percentage change as
%change = (high-low)/low*100
%change= 80 1/4- 50 1/2/50 1/2= 29 3/4/50 1/2 *100
%change= 119/4*2/101 *100= 119/202*100= 0.589*100= 58.9%
%change= 58.9%
