15j + 12k = 18
5j + 4k = 6
Answers
1. multiply the first or second equation by a number that will make one variable 0
For example; if you multiply the bottom equation by “-3”, it will be “-15j-12k=-18”
2. add the two equations together
It will be 15j-15j which equals 0. Additionally, 12k-12k=0. And, 18-18=0
This means that you have 0=0. When this happens, you have infinitely many solutions. Your teacher may only want you to put infinitely many, or they may want you to solve in terms of one of the variables. If it is the latter, let me know and I will help with that.

Find the height of a triangle whose base is 5 inches and area is 12 square inches.
Answers
Answer:
Therefore, Height = 4.8 inches.
Step-by-step explanation:
Given : A triangle whose base is 5 inches and area is 12 square inches.
To find : Find the height of a triangle.
Solution : we have given
Triangle base = 5 inches.
Area = 12 square in.
We need to find height of the triangle.
Area = * base * height .
Plugging the values .
12 = * 5 * height .
On multiplying both sides by 2
24 = 5 * height .
On dividing both sides by 5.
Height = 4.8 inches.
Therefore, Height = 4.8 inches.

The lines represented by the equations y=\frac{4}{5}x+8y= 5 4 x+8 and 20y+25x=18020y+25x=180 are
Answers
Given:
The equations of lines are
[tex]y=\dfrac{4}{5}x+8[/tex]
[tex]20y+25x=180[/tex]
To find:
The relation between two of lines.
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
We have,
[tex]y=\dfrac{4}{5}x+8[/tex] ...(i)
[tex]20y+25x=180[/tex] ...(ii)
Equation (i) can be written as
[tex]20y=-25x+180[/tex]
[tex]y=\dfrac{-25x+180}{20}[/tex]
[tex]y=\dfrac{-25x}{20}+\dfrac{180}{20}[/tex]
[tex]y=\dfrac{-5x}{4}+9[/tex] ...(iii)
On comparing (i) with slope intercept form, we get
[tex]m_1=\dfrac{4}{5}[/tex]
On comparing (iii) with slope intercept form, we get
[tex]m_2=-\dfrac{5}{4}[/tex]
Now,
[tex]m_1\times m_2=\dfrac{4}{5}\times (-\dfrac{5}{4})[/tex]
[tex]m_1\times m_2=-1[/tex]
The product of slopes of both lines is -1. We know that the product of slopes of two perpendicular lines is -1.
Therefore, the given lines are perpendicular.
