No- i don’t not believe it is a function. i would recommend using desmos for graphing :)
Let width be x then
Length is x+8
Therefore area which is given by L*W will be
Area=x*(x=8)
But area =825 sq inches
x*(x+8)=825
x^2+8x-825=0
we use quadratic formula to solve this
and get our x=25 therefore
our width is 25
and length is 33
Answer:
Y= -5/3x -1
Step-by-step explanation:
+2.15.
Explanation: subtract 6.3 by 4.15 = 2.15 so you add 2.15
Answer:
x = −4
Step-by-step explanation:
Add x to both sides of the equation. x + 4 + x = − 4 Add x and x . 2 x + 4 = −4
Subtract 4 from both sides of the equation. 2 x = −4 − 4 Subtract 4 from - 4. 2x = −8
Divide each term in 2x = −8 by 2. 2x/2 = −8/2
Cancel the common factor. 2x/ 2 = −8/2 Divide x by 1. x = −8/2
Divide −8 by 2. x = −4
