The answer is B.) one of the numbers is negative.
So if you take the example...
-3 x -7 = 21
then we know that they equal a positive.
21 ÷ -3 = -7
Um is it 110 let me know if im right
Okay so you see those dots located in the fist question right? locate the coordinates ( 1, 2)
Now that you have located them, look at what the question asks
"move 3 units left and 7 units up" and what you do is move vertices ( 1,2) (aka the dot) 3 units left and move it up 7 times.
And now your new location for (1,2) should be (-2,5) because you moved the (1,2) dot 3 units to the left and 7 units up.
( now do the same for the rest of the other dots)
Answer: (below)
Step-by-step explanation:
The functions shown are exponential functions, which have the form f(x) = a*(b)^x. "a" represents the intial value, while "b" represents the growth factor.
To determine whether a function is growing or decaying, you look at the growth factor. If the growth factor is greater than 1, the function is growing, since each value is getting larger and larger. Meanwhile, if the growth factor is between 0 and 1, the function is decaying, since each value is getting smaller and smaller.
Now, back to this question, let's look at our functions. In the function on the left, the growth factor is 0.87, which is between 0 and 1, so this function is decaying. For the function on the right, the growth factor is 1.25, which is greater than 1, so this function is decaying. Next, let's look at our graphs. In the left graph, the function is growing, so it matches with the function on the right. Meanwhile, in the right graph, the function is decaying, so it matches with the function on the left.
Hope this helps!
