Equation
Divide by 5 on both sides
Plug in for y
Simplify
y=4
slope= 0
y-intercept= 4
Equation
Subtract 3 from both sides
Divide both sides by -1
Plug in for y
Distribute -1 into the parenthesis
Further simplified
y= -15x+3
slope= -15
y-intercept= 3
Equation
Subtract 1/3x from both sides
plug in for y
Simplify
y= -1/3x+17
slope= -1/3
intercept= 17
Answer:
the length is 98 meters and the width 98 meterss
Step-by-step explanation:
We have that the length is l and the width is w, we know that:
P = 2 * w + 2 * l
if we solve for it, we have:
l = P / 2 - w
Now, we know that the area is:
A = l * w
if we replace l, we are left with:
A = (P / 2 - w) * w
A = P * w / 2 - w ^ 2
we derive to know the maximum area and we equal 0 and we have:
A '= P / 2 - 2 * w
0 = P / 2 - 2 * w
w = P / 4
now for him:
l = P / 2 - P / 4
l = P / 4
Therefore, if we replace:
l = 392/4 = 98
w = 392/4 = 98
For the maximum area the length is 98 meters and the width 98 meterss
Answer:
m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46
Step-by-step explanation:
-4m² + 2m - 11 = -5m²
m² + 2m - 11 = 0
m² + 2m + 1 = 12
(m + 1)² = 12
m + 1 = ± √12
m = -1 ± 2√3
I think it is d not sure tho
Answer:
2c^2
Step-by-step explanation:
8c^3d^2/4cd^2
divide the 8 by 4 to get 2
You subtract the powers so c^3-c=c^2 the d^2 cancel each other out
that leaves 2c^2
