answer:
1. yes
2. no
3. yes
4. no
step-by-step explanation:
- for 1, yes because no matter what they are the signs are still the same
- for 2, no because the signs have changed — 2/5 is positive now
- yes because even though there is addition now, the signs are the same. when you use kcc (keep change change), the sign changes to +
- no, because the coefficient for p is changed, which won't be true or give us the same result
To get the function form, the y must be the only variable on one side. So, we need to solve for it.
We have:
-x + y = 6
then we get
y = 6 + x
when we move the x to the other side to get y by itself.

Answer:
the Answer is 3x+12)+X=180
Answer:
x = 79
Step-by-step explanation:
This is an isosecles triangle so the bottom angles have equal measure
and since the sum of interior angles in a triangle is equal to 180
2x + 32 = 180 subtract 32 from both sides
2x = 158 divide both sides by 2
x = 79
The two lines in this system of equations are parallel
Step-by-step explanation:
Let us revise the relation between 2 lines
- If the system of linear equations has one solution, then the two line are intersected
- If the system of linear equations has no solution, then the two line are parallel
- If the system of linear equations has many solutions, then the two line are coincide (over each other)
∵ The system of equation is
3x - 6y = -12 ⇒ (1)
x - 2y = 10 ⇒ (2)
To solve the system using the substitution method, find x in terms of y in equation (2)
∵ x - 2y = 10
- Add 2y to both sides
∴ x = 2y + 10 ⇒ (3)
Substitute x in equation (1) by equation (3)
∵ 3(2y + 10) - 6y = -12
- Simplify the left hand side
∴ 6y + 30 - 6y = -12
- Add like terms in the left hand side
∴ 30 = -12
∴ The left hand side ≠ the right hand side
∴ There is no solution for the system of equations
∴ The system of equations represents two parallel lines
The two lines in this system of equations are parallel
