(2+4)×3
18 would be the answer.
Answer:
a = 2
b = 5
Step-by-step explanation:
![{b}^{0} = 1 \\ a \times 1 = 2 \\ a = 2 \\ (2) \times {b}^{4} = 1250 \\ {b}^{4} = 625 \\ b = 5](https://tex.z-dn.net/?f=%20%7Bb%7D%5E%7B0%7D%20%20%3D%201%20%5C%5C%20a%20%5Ctimes%201%20%3D%202%20%5C%5C%20a%20%3D%202%20%5C%5C%20%282%29%20%5Ctimes%20%20%7Bb%7D%5E%7B4%7D%20%20%3D%201250%20%5C%5C%20%20%7Bb%7D%5E%7B4%7D%20%20%3D%20625%20%5C%5C%20b%20%3D%205)
Answer: 300
Step-by-step explanation:
Rodney's errors on each of the graphs given can be explained as in the explanation below.
<h3>Linear graphs of slope-intercept form equations</h3>
Rodney's error on each of the given linear graphs are as follows;
For y= 30x +10;
- The slope of the graph is 30 and it's intercept is; 10. Hence, the graph should intersect/touch the y-axis at (0,10)
For y= (-1/2)x +5;
- The slope of the given function is; -1/2 and hence, the graph should be a decreasing linear graph.
For y= x -2;
- The slope and intercept of the given function are 1 and -2 respectively. On this note, the graphed line should intersect the y-axis at point (0, -2) and the graph should be an increasing linear graph.
