Answer:
• V = x(11 -2x)(16 -2x)
• x ≈ 2.1 in
Step-by-step explanation:
a) The volume of the box is the product of its depth (x), width (11 -2x) and length (16 -2x). The equation can be simply ...
v(x) = x(11 -2x)(16 -2x)
__
b) A graphing calculator can plot this equation directly. All that is needed is to enter it into the appropriate space provided by the calculator. The value of x that gives the greatest volume is the value that makes the function have a local maximum between x=0 and x=5.5 (where the volume is again zero).
That value of x is about 2.1 inches.
Answer:
choice A. Since 12 -8 = 4 not 5
Step-by-step explanation:
if we plug in x =6 for 2x -8 = 5
2*6 - 8 = 12 - 8 = 4 not 5
Try B. 3*6 + 7 = 18 + 7 = 25 = 25 true
Try C. 4*6 + 12 = 24 + 12 = 36 = 36 true
Try D. 6*6 - 6 = 36 - 6 = 30 = 30 True

Answer:
You can graph them on desmos and see which is a linear (literally looks like a line)
Step-by-step explanation:
The answer is B because u can’t add and negative and a positive exponent
Answer:
C
Step-by-step explanation:
3y - 5x = 15 ... A
y = 5/3 * X +15 .... slope 3/5 , y intercept 15
6y - 10x =30
(6y - 10x) /2 = 30 / 2
3y - 5x = 15 ... B
y = 5/3 * x + 15 ..... slope 3/5 , y intercept 15
∴ Answer is C
