Answer:
Step-by-step explanation:
Given equations:
y = x + 3
y = -x - 1
By comparing the above equations, we get:
x + 3 = -x - 1
Add x to both sides
<h3>x + x + 3 = -1 </h3><h3>2x + 3 = -1</h3>
Subtract 3 to both sides
2x = -1 - 3
2x = -4
Divide 2 to both sides
x = -4/2
<h3>x = -2</h3>
Substitute x = -2 in first equation.
y = x + 3
y = -2 + 3
<h3>y = 1</h3>
So,
<h3>Solution Set = {(x,y)}={(-2,1)}</h3>
First, you multiply 0.7 and 60. 60 will be the minutes that equal one hour.
Finally, we can see that elephant can run up to 42 kilometers per hour. hope this helps!
Answer:
1227 feet
Step-by-step explanation:
Let x is the the length of the base along Michigan
Given:
- The highest of the building is 28 feet less than 7 times the length of the base along Michigan
<=> The highest of the building = 7x -28
- The length of the roof is 65 feet shorter than the length of the base below it.
<=> The length of the roof = x - 65
- The area of one particular side is 149,327.5 square feet
<=> *(7x -28 ) = 149327.5
<=> (2x -65) (7x -28) = 298655
<=> - 511x = 296835
<=> x = 165.
So the building's height is: 7(165) -28 = 1227 feet
