Answer:
A. 40°C B. -10°C per kilometer
Step-by-step explanation:
As the height increase, the temperature decreases.
2, (double) 4, (double) 8 (double) 16, So 16 in week 4
2+4+8+16 = 30
Answer:
3
Step-by-step explanation:
1•5-2
5-2=3
Hello!
Remember that the symbols: ≤ and ≥ are graphed as a solid line. While the symbols: < and > are graphed as a dotted line.
Also, before graphing, it would be better to convert both equations to slope-intercept form.
y ≤ x + 1 is already in slope-intercept form.
y + x ≤ -1 is not written in slope-intercept form. (Slope-intercept form: y = mx + b)
y + x ≤ - 1 (subtract x from both sides)
y ≤ -x - 1
Graphing those lines, you get the graph below. You can see that Part C best represents the solution set systems of inequalities, because that is where both of the shaded lines intersect.
Answer: Part C
