it should be -14 or 0.1 if I'm wrong then I'm sorry
Answer:
27 9/16 21/16 1
Step-by-step explanation:
The table with the input and output values for the exponential function is the following:
x −3 −2 −1 0 1 2 3
f(x) 8/27 8/9 8/3 8 2/4 7/2 2/16
Now we have to take three output values that are three values apart and calculate their ratio. Let's take x=0 and x=-3. The output ratio is:
Let's now take x=1 and x=-2:
And so on:
So, the ratios are:
27 9/16 21/16 1
Answer:
(1, 2 )
Step-by-step explanation:
Given the 2 equations
3x + y = 5 → (1)
5x - 4y = - 3 → (2)
Rearrange (1) expressing y in terms of x by subtracting 3x from both sides
y = 5 - 3x → (3)
Substitute y = 5 - 3x into (2)
5x - 4(5 - 3x) = - 3 ← distribute and simplify left side
5x - 20 + 12x = - 3
17x - 20 = - 3 ( add 20 to both sides )
17x = 17 ( divide both sides by 17 )
x = 1
Substitute x = 1 into (3) for corresponding value of y
y = 5 - 3(1) = 5 - 3 = 2
Solution is (1, 2 )
You have to multiply negative 1 outside of every expression. ex; -1 (1). Each x value now has to be turned into a negative. If i’m not wrong, I assume the y values would also be turned into a negative. Hope this helped :)
