Which graph represents an exponential function?
Answer:
A simple exponential function to graph is y=2x . Notice that the graph has the x -axis as an asymptote on the left, and increases very fast on the right. Changing the base changes the shape of the graph. Replacing x with −x reflects the graph across the y -axis; replacing y with −y reflects it across the x -axis.

Answer:
x=0.25 or -1/4
Step-by-step explanation:
120x + 21 = -9
120x = -30 (-21 from both sides of equation)
x = -0.25 or -1/4 (divide 120 from both sides of equation)
Answer:x=1/4
Step-by-step explanation:
120x + 21 = -9
120x = -9 -21
120=-30
x=-1/4
at school, the maximum number of students that can be in a class room is 22. if there are 25 students signed up for the geometry class, how many more students can join the class?
Answer:
At school, the maximum number of students that can be in a class room is 22. There are 25 students signed up for the geometry class.
Therefore, there are (25-22)=3 extra students.
Hence, no more students can join the class.

from 1954 to 1955 the sales decreased by 80 percent. If the sales in 1956 were the same as the sales in 1954, what was the increased from 1955 to 1956
9514 1404 393
Answer:
400%
Step-by-step explanation:
Suppose sales in 1954 were 500. Then 80% of that amount is 400. A drop of 400 puts sales in 1955 at 500 -400 = 100.
The increase back to 500 in 1956 is an increase of 400 from a base of 100. As a percentage increase, that is ...
400/100 × 100% = 400% . . . . increase from 1955 to 1956

Find the gradient of the line segment between the points (7,2) and (10,-5).
Give your answer in its simplest form.
Given:
Two end points of a line segment are (7,2) and (10,-5).
To find:
The gradient of the given line segment.
Solution:
We know that, gradient of a line segment is the slope of that line segment.
The end points of the line segment are (7,2) and (10,-5), so slope or gradient of the line segment is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-5-2}{10-7}[/tex]
[tex]m=\dfrac{-7}{3}[/tex]
Therefore, the gradient of the given line segment is [tex]\dfrac{-7}{3}[/tex].
In a triangle, the measures of the three angles are x, x + 12 , and x-9. What is the measure of each angle?
Answer:
x+(x+12)+(x-9)=180
3x+12-9=180
3x=180-3
3x=177
x=177/3
x=59
Each angle is 59°, 71° and 500°
I am a 2-digit number. if you double a number and multiply it by 3, it results to 72. what am I?
Answer:
12
Step-by-step explanation:
2x (3) = 72 so 6x = 72 and so x = 12
Answer:12
Step-by-step explanation:
You divide 72 by 3 then that answer by 2 then you get 12. Then if you do 12•2 =24 Then 24 •3 it equals 72

Answer: 12 = x + 4
Step-by-step explanation:
We know that the length of the green line is 12.
And the length of the black line will be equal to the sum of the lengths of the two smaller segments, x, and 4
Then the length of the black line is x + 4
We want to write an equation that says that the length of the green line is equal to the length of the black line, this is:
Length of green line = Length of black line
12 = x + 4
That is the equation we wanted.
Now we could solve it if we subtract 4 in both sides of the equation:
12 - 4 = (x + 4) - 4
8 = x

1. List the properties of a parallelogram
2. Is it possible for a trapezoid to be a parallelogram? Why or why not?
2a. Could a rhombus be a square? Why or why not?
9514 1404 393
Answer:
see the list belownoyesStep-by-step explanation:
1. The dictionary definition of a parallelogram is ...
a quadrilateral with opposite sides parallel
As a consequence of this condition, a number of additional properties arise:
opposite sides are the same lengthopposite angles are congruentadjacent angles are supplementarydiagonals bisect each other__
2. The dictionary definition of a trapezoid (US; trapezium, UK) is ...
a quadrilateral with one pair of parallel sides.
As a consequence of this condition, it is not possible for a trapezoid to be a parallelogram.
__
3. A rhombus is a special case of parallelogram in which all sides are the same length. A square is a special case of rhombus in which all angles are congruent (as are the diagonals). Yes, a rhombus may be a square.
[tex]\displaystyle 2b.[/tex] A rhombus can never be a square because although opposite interiour angles and all four sides are congruent, their interiour angles are not right angles.
[tex]\displaystyle 2a.[/tex] A trapezium is impossibly a parallelogram because a parallelogram has two pairs of parallel sides.
[tex]\displaystyle 1.[/tex] Convex polygon with two pairs of opposite sides that are parallel and congruent [equal in length (see above picture)]

Suman bought a tea pack of 0.345kg. From that, 40g of tea was taken. What
is the amount of tea left with her?Pls answer fast
Answer:
The remaining tea = 0.305 kg
Step-by-step explanation:
The mass of Tea pack = 0.345 kg
The mass of tea taken = 40 g
as
40 g = 0.04 kgTherefore, all we need is to subtract 0.04 kg from 0.345 kg to determine the tea left:
i.e.
Remaining Tea left = Total tea - Tea taken
= 0.345 - 0.04
= 0.305 kg
Therefore, the remaining tea = 0.305 kg

Find the solutions of the quadratic equation -9c² +2 +3 = 0.
Given that,
An equation : -9c² +2c +3 = 0
To find,
Find the value of x.
Solution,
We have, -9c² +2c +3 = 0
We can solve it using the formula as follows :
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
Here, a = -9, b = 2 and c =3
Put the values,
[tex]c=\dfrac{-2\pm \sqrt{(2)^2-4(-9)(3)}}{2(-9)}\\\\c=\dfrac{-2+\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}, \dfrac{-2-\sqrt{(2)^{2}-4(-9)(3)}}{2(-9)}\\\\c=-0.47, 0.69[/tex]
So, the solution are -0.47 and 0.69.

What is 3/11 of 22/39?
Answer:
0.1538
Step-by-step explanation:
first convert 3/11 into a percentage
3÷11=0.272727272727273
0.272727272727273 × 100
27.272727272727/100
27.272727272727%
≈27.27%
27.27% of 22/39
change 22/39 into a decimal
22÷39=0.5641025641》0.564
27.27% of 0.564
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 27.27% * 0.564
Converting percent to decimal:
p = 27.27%/100 = 0.2727
Y = 0.2727 * 0.564
Y = 0.1538
Answer:
2/13Step-by-step explanation:
3/11 of 22/39 is:
22/39 * 3/11 = 22/11 * 3/39 =2*1/13 =2/13
