Answer:
2. y = 7
3. x = 4
Step-by-step explanation:
Slope 0 is when the line is horizontal.. has a constant coordinate
(-5,7) lies on the line so the x-coordinate is 7
Equation: y = 7
A vertical line has all same x-coordinates.
Since (4,-2) is on the line, every point had x-coordinate of 4.
Equation: x = 5
Answer:
0.81241
if i'm wrong i'm rlly rlly sorry!!
No solution because 3rimes something doesn't equal 5
Answer:
2(4x + 1)(x + 1)
Step-by-step explanation:
Given
8x² + 10x + 2 ← factor out 2 from each term
= 2(4x² + 5x + 1)
To factor the quadratic
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 4 × 1 = 4 and sum = + 5
The factors are + 1 and + 4
Use these factors to split the x - term
4x² + x + 4x + 1 ( factor the first/second and third/fourth terms )
= x(4x + 1) + 1 (4x + 1) ← factor out (4x + 1)
= (4x + 1)(x + 1), thus
4x² + 5x + 1 = (4x + 1)(x + 1) and
8x² + 10x + 2 = 2(4x + 1)(x + 1) ← in factored form
