Answer:
B Graph B and D are functions
Step-by-step explanation:
To be a function, it has to pass the vertical line test. The vertical line test says that if you move a vertical line over the graph, it can only touch the graph once at any one time to be a function.
Graph A fails the vertical line test.
Graph B passes the vertical line test
Graph C fails the vertical line test
Graph D passes the vertical line test
Step-by-step explanation:
7+8+10=25cm is the possibile perimeter of this
triangle.
Answer:
D) 5 and 7
Step-by-step explanation:
To find mode, put the numbers and order and see which number repeats the most
4, 5, 5, 6, 7, 7, 8, 12
5 and 7 are the two numbers that repeats the most so the answe is:
D) 5 and 7
Hello,
To solve this question, a good method to use is creating an equation.
The number x being multiplied by 4 can be represented as 4x.
If this results in 25, we can create the equation:
4x = 25
To solve for x, you want to remove the coefficient of 4 from x, so we can divide by 4 on both sides (doing this we will only get x on the left side of the equation, which is what we are trying to solve for).
So, dividing by 4 on both sides, we have
(4x / 4) = (25 / 4)
x = 25/4
x = 25/4, which cannot be further simplified as a fraction. However, this can be represented by 6.25 in decimal form.
x = 25/4, or 6.25
Hope this helps!
