Answer:
Step-by-step explanation:
Y = 3.2x + 5 is a linear function with slope 3.2 and y-intercept 5.
For any x value you choose to substitute for x, you'll obtain a unique y value. For example, if we were to substitute -3 for x, we'd get:
f(-3) = y = 3.2(-3) + 5, or y = -9.6 + 5 = -4.6
There is only one y result for each choice of x.
Y=3.2x+5 alone does not have an "answer." Again: You must pick your own x values and for each such value you must calculate y.
Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation with scale factor 2, multiply by 2.
Answer: The number of ballots increases by 3: 3x3=9, 9x3=27, 27x3=81...
After 10 cuts, there will be 59,049 ballots.
72/6= 12. This means you divide 96 by 12. This is equal to 8. So the final answer is 6/8
<u>Given</u>:
The line graph shows the number of marks Stacey scored in her homeworks.
We need to determine the Stacey's mean score.
<u>Mean score:</u>
The total number of marks is given by

Simplifying, we get;

Thus, the total number of marks is 40.
Sum of the number of marks scored is given by

Thus, the sum of the marks scored is 20.
The mean is given by


Therefore, Stacey's mean score is 2 marks.
