Answer:
The slope of this line is -2
Step-by-step explanation:
2x - 5y =9
-5y = -2x + 9 (Subtract 2x from each side)
y= -2x + 14 (add 5 to each side)
-2 is the slope
Lets say w is the width of the flower bed. We can make an equation to find the area.
The length of the of the flower bed is (w+5) and the width is w.
To find the area we need to multiply the length(w+5) by the width(w) and set it equal to 84,
(w+5)(w)=84
w^2 +5w=84
Using the quadratic equation you get the solutions of 7 and -12. Since 7 is positive it is our width. Our length is 7+5 or 12.
<span>1.) she gave 10 out of the 25 away so written as a fraction would be 10/25. then you dived 10 by 25 and you get .4 after you get the decimal, move the decimal point to the left two places and the answer is 40%.
So the answer is 40%. </span>
Answer: 75
Step-by-step explanation:
The area formula for a trapzoid is area= 1/2 (a+b) h
In this equasion, the substitution would be area=1/2 (10+15) 6
Following PEMDAS, enter the numbers within the parenthases (10+15)
Divide the 25 in half, then multiply by 6. This comes out to 75.
