the meaning of 1, 1.5 is that 1.5 is the oil sad and the 1 is the vinegar.
Step-by-step explanation:
Answer:-35
Step-by-step explanation:
To find 55 more a number equal to 20
We get
Let the number b y
55 more than the number
We be
y+55=20
y=20-55
y=-35
Answer:
2
Step-by-step explanation:
38 total students
5 like neither one, so 38 - 5 = 33
22 plus 13 is 35, but only 33 students like one of them, so 35 - 33 = 2 extra votes, which means 2 like both.
It's not obvious here, but you're being asked to find a linear equation for the velocity of the car, given two points on the line that represents this velocity.
Find the slope of the line segment that connects the points (3 hr, 51 km/hr) and (5 hr, 59 km/hr). Graph this line. Where does this line intersect the y-axis? Find the y-value; it's your "y-intercept," b.
Now write the equation: velocity = (slope of line)*t + b
The units of measurement of "slope of line" must be "km per hour squared," and those of the "y-intercept" must be "km per hour."
Part B: Start with the y-intercept (calculated above). Plot it on the vertical axis of your graph. Now label the horizontal axis in hours: {0, 1, 2, 3, 4, 5, 6}. Draw a vertical line through t=6 hours. It will intercept both the horiz. axis and the sloping line representing the velocity as a function of time. Show only the part of the graph that extends from t=0 hours to t=6 hours.
