9. Alicia and Kyle each are trying to find the solution to the system below. Alicia started by multiplying the top equation by -2.
Kyle started by manipulating the top equation to isolate y.
a. Why did Alicia multiply by-2?

b. Why did Kyle isolate y?

c. Explain why they are both
correct.

You are on a cycling trip around europe with friends. you check the weather forecast for the first week. these are the temperatures for the week. sun mon tues wed thurs fri sat 16°c 20°c 24°c 28°c 28°c 23°c 15°c what is the mean temperature forecast for the week?

Suppose you are going to graph the data in the table. minutes temperature (°c) 0 -2 1 1 2 3 3 4 4 5 5 -4 6 2 7 -3 what data should be represented on each axis, and what should the axis increments be? x-axis: minutes in increments of 1; y-axis: temperature in increments of 5 x-axis: temperature in increments of 5; y-axis: minutes in increments of 1 x-axis: minutes in increments of 1; y-axis: temperature in increments of 1 x-axis: temperature in increments of 1; y-axis: minutes in increments of 5

Write the slope-intercept form of the line that passes through the point (1, 0) and is parallel to x - y = 7. t
