Answer:
A. x=5 is a solution, but x=3 is not
Step-by-step explanation:
When x=5, 11-5<7, 6<7, this is a solution
When x=3, 11-3<3l, 8<7, this is not a solution
Answer:
X=-9
Step-by-step explanation:
Answer:
BD = 78
x = 7
Step-by-step explanation:
As we can see, BC plus CD will be equal to BD. That means we can set up the equation 6x+15+3x = 10x+8. First, we combine like terms to get 9x+15 = 10x+8. Then we can subtract 9x from both sides, to get 15 = x+8. We then subtract 8 from both sides to get x = 7. Since x = 7, we can plug in x for the equation given for BD, 10(7)+8. This will come out to 78.
Answser: the graph of g(x0 is obtained by shifting down 13 units. the graph of f(x).
Explanation:
It is a rule that when you add a constant to a function the graph is shifted upward the number of units that the constant represent, when the constant is posivite, or downward the number of units that the constant represent, whtn the constant is negative.
So, the graph of any function h(x) + k, being k a constant, will be the graph of h(x) shifted k units upward (if k iis positive) or downward (if k is negative).
Then, you have to find how many units you have to add to f(x) = 7x + 9 to become the function g(x) = 7x - 4. That is, find k in:
7x + 9 + k = 7x - 4
⇒ k = - 4 - 9 = - 13.
So, you have that the graph of g(x) = 7x - 4 is found when you add - 13 to add - 13 to the graph of f(x) = 7x + 9.
Which, as explained before is shifting 13 units down.
