Answer:
Step-by-step explanation: It would be 7/20
If x = distance and y = money
the y intercept will be 2 and the slope will be 1/0.5 so:
standerd form: <span>-mx + y = b or -2x + y = 1/0.5
</span>slope intercept: <span>y = mx + b or 2x + 1/0.5</span><span>
point-slope: y=mx+b or y = 2x + 1/0.5
</span>
pls note you might have to simplify the slope in these + check it bc it MIGHT be 0.5/1.
Answer:
Option D is correct
The exponential function is:
Explanation:
An exponential function is in the general form is:
. ......[1]
Given the points (1,12) and (2, 36).
For the point (1,12),
Plug in x = 1 and y =12 in [1]; we get
or
12 =ab ......[2]
Now, for the point (2, 36);
Plug in x= 2 and y =36 in [1];
......[3]
Divide equation [3] by equation [2], we have
Simplify:
Substitute the value of b in equation [2], to solve for a;
Divide both side by 3 we get;
simplify:
Then, put these a and b values in [1]; we get
The exponential function as:
Step 1: simplify 3/25
Step 2: simplify 1608/25
Step 3: divide by 1608/25 3/25
1608/25 / 3/25 = 1608/25 * 25/3
