Answer:

Step-by-step explanation:

The last answer choice is the correct one. The common ratio here is 0.7, which is between 0 and 1, an important criterion for recognizing an exponential decal function. Every time x increases, f(x) will decrease.

Can someone please help

Airida [17]

Answer:

Step-by-step explanation:

We need to use the distance formula, which says that for two points $(x_1,y_1)$ and $(x_2,y_2)$ , the distance between them is:

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Here, the two points are (-2.5, 4.5) and (4.75, 4.5), so:

d = $\sqrt{(4.75-(-2.5))^2+(4.5-4.5)^2}=\sqrt{(7.25)^2+(0)^2}=7.25$ = 7 1/4

The answer is C.

Which answer does NOT correctly describe the graph of y = 5x + 12?

Dafna11 [192]

Answer:

The graph contains the point (5, 12) does NOT correctly describe the graph of y = 5x + 12

Solution:

Given, linear equation in two variable is y = 5x + 12.

We have to select the option that incorrectly describes about given equation.

Now, we have to check one by one option.

a) The line has a constant rate of change.

As the given line is an linear equation it will have constant slope. So this option states correctly

b) The line crosses the y-axis 12 units above the origin

When a line crosses y – axis it x value becomes 0 → y = 5(0) + 12 → y = 12

So, the line crosses the y – axis 12 units above the origin, so this option states correctly.

c) The graph contains the point (5, 12)

To contain (5, 12) in that line → 12 - 5(5) + 12 = 0 but -1 ≠ 0

So, this option is incorrect.

Hence, option c incorrectly describes about the graph.
