In 1 hour, Antoine travels 1.75 mi by dividing 5.25 by 3. So, after lunch, he hiked 4 hours. 1.75 times 2 is 3.5 mi every hour after lunch. So, 3.5 times 4 is 14 mi. + 5.25 is 19.25 mi., or 19 1/4 miles.
2×3=6. And 1/2(2×2)=2. 2+6=8. 8 square units.
y-intercept -3
slope 1/2
is sufficient info with which to write an equation for a straight line:
y = mx + b becomes y = (1/2)x - 3.
You should check this by determining whether or not (2,-1) satisfies this equation.
Answer: 5
Step-by-step explanation:
3 times x = 3x
the difference between 3x and 4 mean that you need to subtract, so the answer is...
3x - 4
