What is an equation of the line that passes through the points ( − 1 , − 2 )and ( − 2 , − 5 ) ?
Answer:
y = 3x + 1
Step-by-step explanation:
You have to use y = m x + c to find the equation of the line.
Here,
m ⇒ slope
c ⇒ y - intercept
First let us find the slope by using the below formula.
For that, let us use the given coordinates.
( -1 , -2 ) ⇒ ( x₁ , y₁ )
(-2 , -5) ⇒ ( x₂ , y₂ )
m = [tex]\frac{y_1-y_2}{x_1-x_2}[/tex]
m = [tex]\frac{-2-(-5)}{-1-(-2)}[/tex]
m = [tex]\frac{-2+5}{-1+2}[/tex]
m = [tex]\frac{3}{1}[/tex]
m = 3
Now we have to find the y - intercept.
For that we can use any coordinate for that.
Let us use ( -1 , -2 ) coordinate.
y = m x + c
-2 = 3 × -1 + c
-2 = -3 + c
- 2 + 3 = c
1 = c
Let us write the equation of the line now.
y = m x + c
y = 3 x + 1
Let me know if you have any other questions. :-)

X-4.6y=-9.8
-X+4.8y=10.4
Answer:
x = 4
y = 3
Step-by-step explanation:
x - 4.6y = -9.8
-x + 4.8y = 10.4
multiply both equations by 5 to remove the decimals in the variables.
we then get this:
5x - 23y = -49
-5x + 24y = 52
multiply one of the equations by -1 to get this
-5x + 23y = 49
-5x + 24y = 52
now subtract the equations
0x -y = -3
y = 3
plug back into equation to get value of x

A type of plant is introduced into an ecosystem and quickly begins to take over. A scientist counts the number of plants
after m months and develops the equation P(m) – 19.3(1.089)" to model the situation. Most recently, the scientist
counted 138 plants. Assuming there are no limiting factors to the growth of the plants, about how many months have
passed since the plants were first introduced?
6.1
O 6.6
O 7.2
O 23.1
It would take about 23.1 months for the plant population to be 138 plants.
Exponential FunctionAn exponential function is in the form:
y = abˣ
Where y,x are variables, a is the initial value of y and b is the multiplication factor.
Given:
[tex]P(m)=19.3(1.089)^m[/tex]
Where P is the plant population after m months.
For a population of 138 plants:
[tex]138=19.3(1.089)^m\\\\m*ln(1..089)=ln(7.15)\\\\m=23.1[/tex]
It would take about 23.1 months for the plant population to be 138 plants.

The net to compute the surface area of the three-dimensional figure is 166 square units.
What is the surface area of the three-dimension figure?
The surface area is the area calculated for the three-dimensional object. As the three-dimensional object is made up of 2D faces, the surface area is the sum of the areas of all the faces of the figure.
A cuboid is a three-dimensional figure having length, width, and height. The surface area of a cuboid can be calculated by adding together the areas of the six faces.
For the given cuboid, length l = 8 , width w = 5 and height h = 5.
The surface area of the figure is given by;
[tex]\rm Area\ of \ Cuboid = 2 lw + 2 lh + 2 wh\\\\Area\ of \ cuboid= 2(7)(5)+2(7)(4)+2(5)(4)\\\\ Area\ of \ cuboid= 70+56+40\\\\Area\ of \ cuboid= 166 \ units^2[/tex]

In the diagram below, DE is parallel to AB. If AB is twice the length of DC,
AC = 28, and DE = 13, find the length of DC. Figures are not necessarily drawn
to scale. State your answer in simplest radical form, if necessary PLEASEEE
Answer:
13.4
Step-by-step explanation:
AB =2DC
So, DC=AB/2
Now, AB/AC=DE/DC
AB/28=13/(AB/2)
AB²=13×28×2
AB=√728
AB=26.98
now, DC=AB/2
=13.4
The length of DC is √182.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .
DE is parallel to AB.
If AB is twice the length of DC, AC = 28, and DE = 13
We have to find the length of DC
DC/AC=DE/AB
x/28=13/2x
Apply cross multiplication
2x²=13×28
2x²=364
Divide both sides by 2
x²=364/2
x²=182
x=√182
Hence, the length of DC is √182.
