Answer:
A
Step-by-step explanation:
use the equation y-1=m(x-x1)
the slope is the same as the m which is the gradient
x1 is 5 and y1 is 2.the x and the y are constants
replace the values given in the equation
y-2=3(x-5)
y-2=3x-15
y=3x-13

Answer:
Plan C=12 weeks for 30 miles walked.
Step-by-step explanation:
This is a constant rate of change...the number of miles each week increased by 10 each time; the number of weeks was divided each time by 2. To find Plan C, divide 24/2, which is 12.
Hope this helps! Have a great day C:
The little square means 90° and a straight line means 180° so 180 minus 68° minus 90° is 22° which leaves,
1) 112° and since you can flip 68° exacly the same on both sides it is a vertical angle which means
3)68.
4) 90°
