3. 1. Solve the equation |x + 2| = 62. Solve the equation |3x - 2| = 2x + 43. Solve |2x - 1| = |x + 4|tolong, Kak. ini harus sekarang
Jawaban:
1. |x+2|=6
x+2=6
x= 6-2
x= 4
x+2=-6
x= -6-2
x= -8
maka hp nya adalah x= -8; x= 4

3x-2= 2x+4
3x-2x= 4+2
x= 6
3x-2= -2x-4
3x+2x= -4+2
5x= -2
x= -2/5
maka hp nya adalah x= -2/5; x=6
3. |2x-1|= |x+4|
2x-1= x+4
2x-x= 4+1
x=5
2x-1= -x-4
2x+x= -4+1
3x= -3
x= -3/3
x= -1
maka hp nya adalah x= -1; x=5
4. Solve the equation 6n + 3= 2n + 31
6n + 3 = 2n + 31
4n = 28
n = 7
Mapel : Matematika dan Bahasa Inggris
Jawaban :
n = 7
Cara:
6n + 3 = 2n + 31
6n - 2n = 31 - 3
4n = 28
n = 28/4
n = 7

12. Solve the equation 8a + 4 = p + 18?
Diketahui :
8a + 4 memiliki hasil operasi yg sama dengan p + 18
Ditanya :
Nilai A?
Nilai P?
Penyelesaian:
8a + 4
= 8² + 4 = 20
Maka nilai A nya adalah 2
p + 18
= 2 + 18 = 20
Maka nilai P nya adalah 2
Maaf apabila salah

14. The equation for the line running through P (-5,2) and Q (3, -4) is
EQUATION of a STRAIGHT LINE
The equation for the line running through P (-5,2) and Q (3,-4) is [tex]y=-\frac{3}{4}x-\frac{7}{4}[/tex].
-------------------
EXPLANATION
Equations of a straight line are written in the form
[tex]y = mx + c[/tex] or [tex]y - mx = c[/tex]
In which [tex]m[/tex] is the gradient of the line and [tex]c[/tex] is the [tex]y[/tex]-intercept or where the graph crosses the y-axis.
The value of [tex]m[/tex] is determined with the formula
[tex]m = \frac{y_{1}-y_{2}}{x_{1}-x_{2}}[/tex]
To find the equation we use
[tex]y-y_{1} = m (x-x_{1})[/tex]
Or, we can bypass finding [tex]m[/tex] with this formula
[tex]\frac{y-y_{1}}{y_{2}-y_{1}}=\frac{x-x_{1}}{x_{2}-x_{1}}[/tex]
--------------
Given:
P is (-5,2)
[tex]x_{1}=-5\\y_{1}=-2[/tex]
Q is (3,-4)
[tex]x_{2}=3\\y_{2}=-4[/tex]
Find:
the equation for the line running through P and Q
Step by step solution:
1. Determine which formula you want to use to find [tex]m[/tex] and [tex]c[/tex]. I use [tex]\frac{y-y_{1}}{y_{2}-y_{1}}=\frac{x-x_{1}}{x_{2}-x_{1}}[/tex] because it is simpler IMHO.
[tex]\frac{y-y_{1}}{y_{2}-y_{1}}=\frac{x-x_{1}}{x_{2}-x_{1}} \\\frac{y-2}{(-4)-2}=\frac{x-(-5)}{3-(-5)}\\\frac{y-2}{-6}=\frac{x+5}{8}\\[/tex]
2. Cross multiply the two fractions
[tex]8(y-2)=-6(x+5)\\8y-16=-6x-30\\[/tex]
3. Put the above equation into the [tex](n)y = mx + c[/tex] form
[tex]8y=-6x-30+16\\8y=-6x-14[/tex]
3. Now, we need to put it in the [tex]y = mx + c[/tex] form. Do this by dividing the equation with 8.
[tex]\frac{8y=-6x-14}{8}\\y=-\frac{6}{8}x-\frac{14}{8}\\[/tex]
4. Simplify the fractions and we get
[tex]y=-\frac{3}{4}x-\frac{7}{4}[/tex]
Thus, the equation for the line running through P (-5,2) and Q (3,-4) is [tex]y=-\frac{3}{4}x-\frac{7}{4}[/tex]
or
[tex]y=-0,75x-1,75[/tex].
