Lizette ran for 1.25 hours and walked for 3 hours.
distance = speed × time
Her total distance is the sum of her distances at the different speeds. Let w represent her walking speed in mi/h. For distances in miles, speeds in miles per hour, and time in hours, the problem statement tells us ...
19 = (w+5)(1.25) + (w)(3)
19 = 4.25w + 6.25 . . . . collect terms
12.75 = 4.25w . . . . . . . subtract 6.25
3 = w . . . . . . . . . . . . . . . divide by 4.25
Lizette's walking speed is 3 mph.
Lizette's running speed is 8 mph.
Answer:
A ) 8 times
Explanation:
There are two 1's shown on the spinner out of 6 numbers. The probablility of rolling a 1 is 2/6 or 1/3.
If you spin the spinner 24 times, you need to multiply the probablility by 24 or 1/3 x 24, which is 8.
In order to name the coordinates, you read the X axis first and then the Y axis. So A would be (-4, 4). B would be (-4, 6). C would be (2, 4).
They are not congruent because each angle is a different measure.
Hope this helped! :)
Simply substitute x by its value:
1)
f(x) = x + 4 ; x = 3p f(x) = x + 4 ;
f(3p) = 3p + 4 f(1) = 1 + 4
f(1) = 5
x = 3p (1,5)
y = 3p + 4
2) g(x) = 3(x-2) g(x) = 3(x-2)
g(x) = 6 g(1) = 3(1-2)
g(1) = 3 - 6
6 = 3x - 6 g(1) = -3
6+6 = 3x (1,-3)
12 = 3x
x = 4
g(4) = 3(4-2)
g(4) = 12 - 6
g(4) = 6
x = 4
y = 6
