Answer:
12 3/8
Step-by-step explanation:
6 1/2 + 5 7/8 =
= 6 4/8 + 5 7/8
= 11 11/8
= 11 + 8/8 + 3/8
= 11 + 1 + 3/8
= 12 3/8
To find the x-intercept you must make y=0
3x+2y=12 - substitute 0 for y
3x+2(0)=12 - multiply 2 and 0
3x+0=12 - add zero
3x=12 - divide by 3
x=4
To find the y-intercept you must make x=0
3x+2y=12 - substitute 0 for x
3(0)+2y=12 - multiply 3 and 0
0+2y=12 - add 0 and 2y
2y=12 - divide by 2
y=6
-4(-1.5 - 9)
-4 x -1.5 = 6
-4 x 9 = -36
Answer is -30
Answer:
solution
is
you minus smallest x(you minus because the opposite of positive ia negative)
so you do x-x=0 and 4-x=3
so 2y/2. and 3÷2
so x is 1.5
for the 2nd question 3x -2y= -12
you do add 2y on both sides
so -2y+2y =0 and -12 +2y= -10 y
so 3x/3 and -10y /3
x= - 3.3333333333

The solution of the quadratic equation is x = 0 or x = 6 ⇒ 4th answer
Step-by-step explanation:
The form of the quadratic equation is ax² + bx + c = 0, where
- a is the coefficient of x²
- b is the coefficient of x
- c is the numerical term
The quadratic equations has two roots, to find them factorize it into two factors and equate each factor by zero
∵ 3x = 0.5 x²
- Subtract 3x from both sides
∴ 0 = 0.5x² - 3x
- Multiply both sides by 2 to make the coefficient of x² integer
∴ 0 = x² - 6x
- Switch the two sides
∴ x² - 6x = 0
- Factorize it by taking x as a common factor
∴ x(x - 6) = 0
- Equate each factor by 0
∴ x = 0 → 1st root
∴ x - 6 = 0
- Add 6 to both sides
∴ x = 6 → 2nd root
∴ The roots of the equation are 0 or 6
The solution of the quadratic equation is x = 0 or x = 6
