Angle 1 = 8x + 45
Angle 2 = x
x + 8x + 45 = 180
combine like terms
9x + 45 = 180
subtract 45 from both sides
9x = 135
divide both sides by 9 to isolate x
x = 15
Angle 1 = 8(15) + 45 = 165 degrees
Angle 2 = 15 degrees
Answer:
y = -1
Step-by-step explanation:
3(2) + y = 5
6 + y = 5
-6
y = 5 -6
y = -1
Answer:
1) 75 copies were sold
2)expected wage=720
Step-by-step explanation:
in this equation, y represents wages and x represents number of copies sold
lets take the trendline, y=6x+120
since the amount earnt is $570, we can take this to be our y variable
570=6x+120
450=6x
x=75
1) 75 copies r sold
2) this time we substitue the 100 for x
y=6(100)+120
y=600+120
y=720
2) expected wage=720
Answer:
yes they r

Answer:
Scenario 1 represents a greater speed
Step-by-step explanation:
scenario 1 - find equation of line on graph to compare
- use the points given to find the slope
rate = slope = (y2-y1)/(x2-x1) = (240-60)/(4-1) = 60
y intercept = 0
line equation -> y = 60x
for every mile, 60 miles are traveled
scenario 2 - interpret the equation
for every mile, 50 miles are traveled
Scenario 1 represents a greater speed
