Answer:
-5/24
Step-by-step explanation:
-3/8 =
-9/24
1/6 =
4/24
-9/24+4/24=-5/24
Answer:
-3
Step-by-step explanation:
multiply to make it a common number so -3/8 times 6/6 and 1/6 times 8/8
so -18/48 times 8/48. Then you multiply the top numbers to get 144/48. Then you simplify or divide so -3.
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)

Eric started at sea level. He descended 13.7 meters and then ascended 15.2 meters. Write an additional expression in the form Descent + Ascent to represent this situation. Then calculate the sum and explain what it represents.
An additional expression in the form Descent + Ascent to represent this situation is -13.7 + 15.2. The sum will be 1.5 meters.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Eric started at sea level. He descended 13.7 meters and then ascended 15.2 meters.
The expression will be written as,
E = -13.7 + 15.2.
E = 1.5 meters
Therefore, the additional expression in the form Descent + Ascent to represent this situation is -13.7 + 15.2. The sum will be 1.5 meters.

5) Solve for x,
107 + 44
8x -23
Answer:
8x + 128??
Step-by-step explanation:
Answer:
To start off, lets label this triangle ABC where A is the top right vertical, the top left verticle is B, and the bottom one is C. Now lets label the 2 points of intersection from the line segment 8x-23 D and E where the left intersection is E and the right is D.
Notice how CE and AE have an arc and that AC was split to get AE and CE. The 2 arcs show us that the intersection E is located at half the line segment.
This is the same on the other line segment BC. So if E and D are half of those line segments then the line segment ED must be half of the parallel segment above it. Because this is true, 2(8x-23)=10x+44
Now we have an equation and we can solve:
2(8x-23)=10x+44
16x-46=10x+44
6x-46=44
6x=90
x=15

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.

Work out the area of a rectangle with base, b =
18mm and perimeter, P = 60mm.
b b
Answer:
Area of rectangle = 216 square mm
Step-by-step explanation:
Base (b ) = 18 mm
width = 'x' mm
Perimeter of rectangle = 2*(base + width)
Perimeter = 60 mm
2*(base + width) = 60 mm
2 *(18 + x ) = 60
2*18 + 2*x = 60
36 + 2x = 60
2x = 60 - 36
2x = 24
x = 24/2
x = 12
Width = 12 mm
Area of rectangle = base * width
= 18 * 12
= 216 square mm
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

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]
Alain lanzó una piedra desde un puente al río de abajo.
La altura de la piedra (en metros sobre el agua) xxx segundos después de que Alain la lanzó está modelada por:
h(x)=-5x^2+10x+15h(x)=−5x
2
+10x+15h, left parenthesis, x, right parenthesis, equals, minus, 5, x, squared, plus, 10, x, plus, 15
¿Cuál es la altura de la piedra en el momento que la lanza?
Responder:
15m
Explicación paso a paso:
Dada la expresión de la altura de la pelota lanzada modelada por la ecuación;
h (x) = -5x² + 10x + 15
El momento en que se arrojó la piedra es cero, es decir, x = 0 segundos
Sustituya x = 0 en la ecuación y encuentre h (x) como se muestra;
h (x) = -5x² + 10x + 15
h (0) = -5 (0) ² + 10 (0) +15
h (0) = 0 + 0 + 15
h (0) = 15 m
De ahí que la altura de la piedra cuando la arrojes sea de 15 m
