9^3 x 8 is the answer I believe
Answer:
The graph of a linear equation is a straight line. The "solution" to a system of two linear equations is the point where the two lines cross. If the two lines are parallel, they never cross; hence parallel lines have no solution. Two lines are parallel if they have the same slope (the m value in y = mx+b). One of your equations is y = -2x + (you left the y-intercept out). The slope is -2. So any line with a slope of m = -2 will be parallel to this line and will not cross it. The second line also needs a different value of b, the y-intercept. Otherwise it is the same line and every point is a solution. So if your equation is:
y = -2x + 1
Then any equation of the form y = -2x + b, b≠1 will create a system with no solution. Hence the values of m and b are m = -2, b ≠ 1.

Answer:
£5.41
Step-by-step explanation:
7.25/1.34 = 5.41044...
Round = 5.41
Your equation for number one is 600,788,188/760,507,625 = x/100
After cross multiplying you will get 760,507,625x = 60,078,818,800
Then you will divide by <span>760,507,625 to isolate the varible to get 78.99 = x.
Your equation in number two is 80/143 = x/100 because when you subtract 143 by 63 you get 80, the amount of males in the room. Then you cross multiply to get, 143x = 8000. Then you would divide both sides by 143 to isolate the varible to get 55%</span>
