Answer:
3.7001 × 10 to the power of 4 is the answer for #1
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
The correct answer is y = -2x + 16. In slope-intercept form, the formula is y = mx + b, where m is the slope and b is the y-intercept, or the place where the line crosses the y-axis. For this line, the y-intercept is positive 16, because the line crosses the y-axis at 16. Therefore, we know that the equation is y = mx + 16. Now, we just need to find the slope. By counting squares, we can see that the line goes down 4 and right 2. You can check this by taking two points on the line and subtracting them. For instance, the line goes from y 16 to y 12, which has a 4 unit difference. Therefore, the line goes down 4. It goes from x 0 to x 2, meaning that there is a difference of 2 between them, and, since the line is going right, the 2 is positive. Since slope = y/x, the slope is -4/2, or -2. Therefore, the slope is -2.
Adding all this together, the slope in slope-intercept form is y = -2x + 16.
