Answer:
3(x+4)=5x-9
or,3x+12=5x-9
or,12+9=5x-3x
or,21=2x
orx=21/2
x=10.5
The value of x from the given rectangle is 10.5 units.
The opposite sides of a rectangle are 3(x+4) and 5x-9.
What is a rectangle?A rectangle is a closed two-dimensional figure with four sides. The opposite sides of a rectangle are equal and parallel to each other and all the angles of a rectangle are equal to 90°.
Now, the opposite sides of a rectangle are congruent
So, 3(x+4) = 5x-9
⇒ 3x+12=5x-9
⇒ 5x-3x=12+9
⇒ 2x=21
⇒ x=10.5 units
Therefore, the value of x from the given rectangle is 10.5 units.

Answer:
The three integers are:-17,-15,-13
Answer:
13, 15, 17 (the set)
Step-by-step explanation:
To find the middle number, you just divide 45 by 3 since you have three consecutive digits.
45/3 = 15 = the middle number
13, 15, 17 (+2, and -2 from 15 since has to be odd)

The table below represents the amount, in grams, of a substance remaining after t years.
Answer:
D
Step-by-step explanation:
The equation we'd use for this problem is y=a(1-b)^x (exponential decrease)
a is the initial amount, the number in the parentheses is the amount it decreases by, and x is time.
The initial amount is 8,500 since that is what we start with after 0 years. By looking at the chart we can see that the number decreases over time by a constant rate of .5, so that is the number in the parentheses. You then end the equation with ^t since t would be time in years

Café 103 is collinear with and halfway between the Metrics School and the
Angles Lab. The Metrics School is located at point (2, 6) on a coordinate
plane, and Angles Lab is at point (7, 2). Find the location of Café 103.
The location of Café 103 is (4.5, 4)
How to determine the location of Café 103?The given parameters are
Metrics School = (2, 6) on a coordinateAngles Lab = (7, 2) on a coordinateFrom the question, we understand that:
Café 103 is collinear with and halfway between the Metrics School and the Angles Lab.
This means that Café 103 is at the midpoint
So, we have:
Café 103 = 0.5 * (x1 + x2, y1 + y2)
This gives
Café 103 = 0.5 * (2+ 7, 6 + 2)
Evaluate
Café 103 = (4.5, 4)
Hence, the location of Café 103 is (4.5, 4)

△FGH represents an artist's initial work on a design for a new postage stamp. What must be the values of x, y, and z in order for the artist's stamp to be congruent to △ABC?
The values of x, y, and z in order for the artist's stamp to be congruent to △ABC is 15, 6, and 4 respectively
Given data
The two triangle that has the values are attached:
How to find the value of x, y, and z to make the triangles congruentThe value of x
( 2x + 6 ) mm = 36 mm
2x mm = ( 36 - 6 ) mm
2x mm = 30 mm
x = 30 / 2 mm
x = 15 mm
The value of y
( 6y ) mm = 36 mm
y = 36 / 6 mm
y = 6 mm
The value of z
( 3z + 39 ) mm = 51 mm
3z mm = ( 51 - 39 ) mm
3z mm = 12 mm
z = 12 / 3 mm
z = 4 mm
Therefore, the values of x, y, and z in order for the artist's stamp to be congruent to △ABC is 15, 6, and 4 respectively

Different range charts. Column range—Columns are used in the Column Range chart to illustrate the range.
Bar range—Bars are used in the Bar Range chart to illustrate the range.
smooth range-Curved lines rather than straight ones connect the data points in a smooth range chart.
From the graph it is shown as it has closed points on both ends so both the values -9 and -4 are inclusive in the range y axis
So it is written as (-9,-4) and also be written as -9≤y≤-4

There is a lower limit but no upper limit for a random variable that follows the exponential probability distribution.
We know that, an exponential distribution is a type of continuous distributions.

The exponential distribution is memoryless.
