2. Help ASAPfind the equation of line that pass the point -2,4 and 3,-6
Jawaban:
y = -2x
Penjelasan dengan langkah-langkah:
x1 = -2, y1 = 4, x2 = 3, y2 = -6
Now, we substitute that points to
(y - y1)/(y2 - y1) = (x - x1)/(x2 - x1)
(y - 4)/(-6 - 4) = (x + 2)/(3 + 2)
(y-4)/(-10) = (x+2)/5
5y - 20 = -10x - 20
5y = -10x
y = -2x
So, the equation of line that pass the point (-2,4) and (3,-6) is y = -2x

4. The difference between a number and three is multiplied by negative six. The result is eighteen. What is the number? Write an equation that can be used to find the number, n. Solve the equation you wrote in part A to find the value of the number. Include all of your work in your answer.
Algebraic eguation
The difference between a number and three is multiplied by negative six. The result is eighteen.
The number = n
Equation:
(n - 3) * (-6) = 18
The value of the number is 0.
(n - 3) = 18 ÷ (-6)
(n - 3) = (-3)
n = (-3) + 3
n = 0
ーーーーー
Penjelasan
difference = selisih
jadi selisih sebuah angka (n) dengan 3 dikali -6 hasilnya adalah 18.
Persamaannya adalah:
(n - 3) * -6 = 18
Nilai n dari persamaan tersebut adalah 0.

5. 6 × (5x-3)=15 find x in each equation
6 ( 5x - 3 ) = 15
30x - 18 = 15
30x = 33
x = 1,1
6 × (5x-3)=15

7. Given that a = 2x + 4, b = -x + 1, a = b. Write down an equation in x and solve it!
a = b
2x + 4 = -x + 1
2x + x = 1 - 4
3x = -3
x = -1
Chapter : Linear Equation
given that a = b , and we got :
a = b
2x + 4 = -x + 1
2x + x = 1 - 4
3x = -3
x = -1
So, the value of x is -1 . Hence, we can also get the value of a dan b :
a = b = -x + 1
a = b = -(-3) + 1
a = b = 3 + 1
a = b = 4
8. show that the equation log10(x-4)=2-log10x can be written as quadratic equation in x
Penjelasan dengan langkah-langkah:
[tex] log10(x - 4) = 2 - log10x[/tex]
[tex] log10(x - 4) = log(100 ) - log10x [/tex]
[tex] log10(x - 4) = log( \frac{100}{10x} ) [/tex]
[tex]10(x - 4) = \frac{100}{10x} [/tex]
[tex](x - 4) = \frac{1}{x} [/tex]
[tex] {x }^{2} - 4x = 1[/tex]
[tex] {x}^{2} - 4x - 1 = 0[/tex]
gunakan rumus ABC
x1,2 = (4 ±2√5)/2
x1,2= 2 ±√5
x1= 2-√5
x2=2+√5

12. Find the equation of the line passing through the point (6,3) that is perpendicular to the line 4x−5y=−10. Step 1: Find the slope of the line 4x−5y=−10.What would the perpendicular slope be?Step 2: Use the slope to find the y-intercept of the perpendicular line.Step 3: Write the equation of the line that passes through the point (6,3) that is perpendicular to the line 4x−5y=−10
Find the equation of the line passing through the point (6,3) that is perpendicular to the line 4x - 5y = -10?
Solution :
4x - 5y = -10
- 5y = 4x - 10
Divide both sides by -5
y = (4/-5)x - (10/-5)
y = (-4/5)x + 2
From the slope intercept form we get
m = - 4/5
The slope of a perpendicular is a negative inverse of - 4/5
m = (5/4)
Slope intercept form for the perpendicular line is
y = (5/4) x +b
Solve for b using (6, 3)
3 = (5/4) (6) + b
3 = 30/4 + b
b = 3 - 30/4
b = (12 - 30)/4
b = -18/4
b = -9/2
So the perpendicular line is y = (5/4)x - 9/2
The equation of the line passing through the point (6,3) that is perpendicular to the line 4x-5y=-10 is y = (5/4)x - 9/2.

16. Given that x = 7t - 48, y = -15t - 4, x = y. Write down an equation in t and solve it
Jawab:
t = 2
Penjelasan dengan langkah-langkah:
x = 7t - 48
y = -15t - 4
Because x = y, we can make an equation like this :
x = y
7t - 48 = -15t - 4
22t = 44
t = 2
So the value of t = 2.
Chapter : Linear Equation
Given that :
x = 7t - 48
y = -15t - 4
x = y , Hence we got :
7t - 48 = -15t - 4
7t + 15t = -4 + 48
22t = 44
t = 2
So , we have a value of t = 2
