42 because it is all of the sides have to be added up for the perimeter so the formula would be 14+14+7+7.
Subtract 3 from both sides
-12u = 8v + 1 - 3
Simplify 8v + 1 - 3 to 8v - 2
-12u = 8v - 2
Divide both sides by -12
u = - 8v - 2/12
Factor out the common term 2
u = - 2(4v - 1)/12
Simplify 2(4v - 1)/12 to 4v - 1/6
u = - 4v - 1/6
Hey girl! It's me again to explain this to you :)
Number 21.) If we start from our y-intercept -2 and move up 2 on our y-axis we get to point (0,0). If we move over 1 space to the right, we are on (1,0), which is the x-intercept.
Slope: 2/1 or just 2
Y-intercept: -2
You didn't ask for this but i'm gonna write it anyways. The equation for this line is y=2x-2
Number 22.) If we start from our y-intercept 2 and move down 2 on your y-axis we get to point (0,0). If we move over 1 space to the right, we are on (1,0), which is the x-intercept.
Slope: -2/1 or just -2
Y-intercept: 2
Again you didn't ask for this but the equation for this line is y=-2x+2
Hope this helped you understand and again make this brainliest and reply if you need more help or have any more questions :)
Step-by-step explanation:
You will travel 4 km in 10 minutes. 24km/hr is 24/60 so you would reduce it down to 4/10. so 4km
