Answer:
The rate of change is 27.5 miles per hour
Step-by-step explanation:
Given:
Distance driven by mike = 110 miles
Time taken by mike to drive 110 miles = 4 hours
To Find:
Rate of change=?
Solution:
The rate of change is also known as speed . Here we have to find the speed at which the mike drives
So we know that
Substituting the values
Speed =
Speed =27.5
The reason why the trails must be in quadrant 2 or 3 is because the coordinates start with a negative number. Quadrant 2= (-,+) and quadrant 3= (-,-)
Answer:
x =5
Step-by-step explanation:
transfer -2 to the other side it turns to +2
|2x-1|=7 +2
2x-1 =9
transfer -1 to the other side it turns to +1
2x=10
Divide both sides by 2
2x /2 = 10/2
x= 5
142 houses can be built
71/2 reduces to 35.5
35.5/.25 = 142
Answer:
108 degrees
Step-by-step explanation:
Since angles A and B are supplementary, they both add up to 180. Angle A = 7x+10, and angle B = 7x-26. You can set up the equation A + B = 180, and then plug in angles A and B, which gives you 7x+10 + 7x-26 = 180. Then you just need to isolate x:
Combine like terms: 14x - 16 = 180
Add 16 to both sides: 14x = 196
Divide both sides by 14: x = 14
Now that you know x, you can plug it into the expression for angle A (7x+10):
A = 7(14) + 10 = 98+10 = 108
