Eleanor and Max used two rectangular wooden boards to make a set for
the school play. One board was 6 feet long, and the other was 5 feet
long. The two boards had equal widths. The total area of the set was
60 square feet. What was the width?
Answer:
[tex]\frac{60}{11}[/tex] feet
Step-by-step explanation:
Rectangle 1:
6 x Width = Area
Rectangle 2:
5 x Width = Area
Total Area = Area of Rectangle 1 + Area of Rectangle 2 = 60 square feet
Take Width as [tex]x[/tex] as the widths of both rectangles are the same:
[tex]5x + 6x = 60\\\\11x = 60\\\\x = \frac{60}{11}[/tex]

I got absolute minimum wrong
9514 1404 393
Answer:
absolute maximum: (3, 27e^-3) ≈ (3, 1.24425)absolute minimum: (-4, -64e^4) ≈ (-4, -3494.28)Step-by-step explanation:
The absolute extremes will be at one of two locations:
where the derivative is zeroat an end of the intervalHere, the absolute maximum occurs where the derivative is zero (and the second derivative is negative).
f'(x) = 3x^2·e^-x -x^3·e^-x = x^2·e^-x·(3 -x) ⇒ f'(3) = 0
The absolute minimum occurs at the left end of the interval, where both x^3 and e^-x have large magnitude.
The minimum is ...
(-4)^3×e^-(-4) ≈ -3494.21 . . . . six significant figures
__
A graph can show you the function tends toward -∞ as x goes to large negative values. Hence, the absolute minimum on an interval beginning in the left half-plane will be at the left end of the interval.

please answer I'll mark brainlyest!!!!!
I really need Step my step answer full sentences and full answers and right answers please help me!
Answer:
a.
[tex]Length = 25[/tex]
[tex]Width = 14[/tex]
[tex]Perimeter = 78ft[/tex]
b.
[tex]Length = 25.2[/tex]
[tex]Width = 13.6[/tex]
[tex]Perimeter = 77.6ft[/tex]
c.
[tex]Perimeter = 77.54ft[/tex]
Estimate (b) is closer to the actual measurement.
Step-by-step explanation:
Given
[tex]Length = 25.15[/tex]
[tex]Width = 13.62[/tex]
Solving (a): Approximate measurements to whole numbers then estimate the perimeter.
When approximated to whole numbers (i.e. no decimal place), the new measurement is:
[tex]Length = 25[/tex]
[tex]Width = 14[/tex]
The perimeter is calculated as thus:
[tex]Perimeter = 2(Length + Width)[/tex]
[tex]Perimeter = 2(25 + 14)[/tex]
[tex]Perimeter = 2*39[/tex]
[tex]Perimeter = 78ft[/tex]
Solving (b): Approximate measurements to tenth then estimate the perimeter.
When approximated to tenth (i.e. to 1 decimal place), the new measurement is:
[tex]Length = 25.2[/tex]
[tex]Width = 13.6[/tex]
The perimeter is calculated as thus:
[tex]Perimeter = 2(Length + Width)[/tex]
[tex]Perimeter = 2(25.2 + 13.6)[/tex]
[tex]Perimeter = 2*38.8[/tex]
[tex]Perimeter = 77.6ft[/tex]
Solving (c): Exact Perimeter.
Given measurements are:
[tex]Length = 25.15[/tex]
[tex]Width = 13.62[/tex]
The perimeter is calculated as thus:
[tex]Perimeter = 2(Length + Width)[/tex]
[tex]Perimeter = 2(25.15 + 13.62)[/tex]
[tex]Perimeter = 2*38.77[/tex]
[tex]Perimeter = 77.54ft[/tex]
To determine which is nearest, we calculate the absolute difference between each estimate from the actual measurement.
For estimate a
[tex]Difference = |77.54 - 78|[/tex]
[tex]Difference = |-0.46|[/tex]
[tex]Difference = 0.46ft[/tex]
For estimate b
[tex]Difference = |77.54 - 77.6|[/tex]
[tex]Difference = |-0.06|[/tex]
[tex]Difference = 0.06ft[/tex]
The closest to the exact is the one with the smallest difference.
Hence, estimate (b) is closer to the actual measurement.

Answer:
[tex] Slope (m) = -\frac{3}{4} [/tex]
Step-by-step explanation:
Using any two pairs from the table of values given, (-2, 5) and (2, 2):
[tex] Slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Where,
[tex] (-2, 5) = (x_1, y_1) [/tex]
[tex] (2, 2) = (x_2, y_2) [/tex]
Plug in the value into the slope formula:
[tex] Slope (m) = \frac{2 - 5}{2 -(-2)} [/tex]
[tex] Slope (m) = -\frac{3}{4} [/tex]
the point P has coordinates (2,1) and the point Q has coordinates(-2,-1). Find out the equation of the perpendicular bisector of PQ
Answer: y = -2x
M is the midpoint of PQ
=> M(0;0)
the line PQ passes through P(2;1) and Q(-2;-1)
=> (PQ): 2x - 4y = 0
have:
(d): perpendicular (PQ)
passes throgh M(0;0)
=> (d): 4x + 2y = 0 ⇔ y = -2x
Step-by-step explanation:
The equation of the perpendicular bisector of PQ is,
⇒ y = - 2x
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point P has coordinates (2, 1) and the point Q has coordinates(-2, -1).
Hence, The slope of line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 1 - 1) / (- 2 - 2)
m = - 2 / - 4
m = 1/2
Thus, The slope of perpendicular line is,
⇒ m = - 2
The midpoint of coordinates (2, 1) and (- 2, - 1) is,
⇒ (- 1 + 1) / 2 , (- 2 + 2) / 2
⇒ (0, 0)
Hence, The equation of line is,
⇒ y = mx + b
⇒ 0 = - 2 × 0 + b
⇒ b = 0
Hence, The equation of the perpendicular bisector of PQ is,
⇒ y = - 2x

What is the x-value of the solution to the system of equations?
5x + 4y = 8
2x − 3y = 17
Answer:
x=4
Step-by-step explanation:
multiply first eq. by 3 and second by 4 to get rid of y
15x+12y=24
8x-12y=68
add the equations
23x = 92
divide both sides by 23
x=92/23=4
Answer:
x = 4
Step-by-step explanation:
Given the 2 equations
5x + 4y = 8 → (1)
2x - 3y = 17 → (2)
Multiplying (1) by 3 and (2) by 4 then adding will eliminate the y- term
15x + 12y = 24 → (3)
8x - 12y = 68 → (4)
Add (3) and (4) term by term to eliminate y, that is
23x = 92 ( divide both sides by 23 )
x = 4

Solve the compound inequality, and show work!
Answer:
[tex]x\geq 6\text{ or } x<-3[/tex]
Step-by-step explanation:
We have the compound inequality:
[tex]2(x-1)\geq10\text{ or } 3-4x>15[/tex]
Let's solve each of them individually first:
We have:
[tex]2(x-1)\geq10[/tex]
Divide both sides by 2:
[tex]x-1\geq5[/tex]
Add 1 to both sides:
[tex]x\geq6[/tex]
We have:
[tex]3-4x>15[/tex]
Subtract from both sides:
[tex]-4x>12[/tex]
Divide both sides by -4:
[tex]x<-3[/tex]
Hence, our solution set is:
[tex]x\geq 6\text{ or } x<-3[/tex]
Answer:
x ≥ 6 or x < -3

2(x-1) ≥ 10 or 3 - 4x > 15

THis table gives a few (x, y) pairs of a line in the coordinate plane.
x ......y
48 -30
61 -45
74 -60
What is the x-intercept of the line?
Answer:
The x-intercept is : (22, 0)
Step-by-step explanation:
Given the table
x y
48 30
61 45
74 60
From the table, it is clear that every y value is changing 15 units, and every x is changing 13 units. Hence, it is a straight line.
Hence, we can find the other values of this straight line as well.
so
When the value of y = 15 i.e. (30-15), then the value of x will
be 35 i.e. (48 - 13).
as
y = 30 - 15 = 15, and x = 48 - 13 = 35.
Similarly,
When the value of y = 0 i.e. (15-15), then the value of x will be 22 i.e. (35-13).
as
y = 15-15 = 0, and x = 35 - 13 = 22.
As we know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.
so, as we have checked that when the value of y = 0, then the value of x = 22.
Therefore, the x-intercept is : (22, 0)

Answer:
[tex]\displaystyle y=\frac{16-9x^3}{2x^3 - 3}[/tex]
[tex]\displaystyle y=-\frac{56}{13}[/tex]
Step-by-step explanation:
Equation Solving
We are given the equation:
[tex]\displaystyle x=\sqrt[3]{\frac{3y+16}{2y+9}}[/tex]
i)
To make y as a subject, we need to isolate y, that is, leaving it alone in the left side of the equation, and an expression with no y's to the right side.
We have to make it in steps like follows.
Cube both sides:
[tex]\displaystyle x^3=\left(\sqrt[3]{\frac{3y+16}{2y+9}}\right)^3[/tex]
Simplify the radical with the cube:
[tex]\displaystyle x^3=\frac{3y+16}{2y+9}[/tex]
Multiply by 2y+9
[tex]\displaystyle x^3(2y+9)=\frac{3y+16}{2y+9}(2y+9)[/tex]
Simplify:
[tex]\displaystyle x^3(2y+9)=3y+16[/tex]
Operate the parentheses:
[tex]\displaystyle x^3(2y)+x^3(9)=3y+16[/tex]
[tex]\displaystyle 2x^3y+9x^3=3y+16[/tex]
Subtract 3y and [tex]9x^3[/tex]:
[tex]\displaystyle 2x^3y - 3y=16-9x^3[/tex]
Factor y out of the left side:
[tex]\displaystyle y(2x^3 - 3)=16-9x^3[/tex]
Divide by [tex]2x^3 - 3[/tex]:
[tex]\mathbf{\displaystyle y=\frac{16-9x^3}{2x^3 - 3}}[/tex]
ii) To find y when x=2, substitute:
[tex]\displaystyle y=\frac{16-9\cdot 2^3}{2\cdot 2^3 - 3}[/tex]
[tex]\displaystyle y=\frac{16-9\cdot 8}{2\cdot 8 - 3}[/tex]
[tex]\displaystyle y=\frac{16-72}{16- 3}[/tex]
[tex]\displaystyle y=\frac{-56}{13}[/tex]
[tex]\mathbf{\displaystyle y=-\frac{56}{13}}[/tex]
