Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x - 6 is in this form with slope m = 5
• Parallel lines have equal slopes
y = 5x - 2 is the only line with a slope of 5 → B
Answer:
(a + 2b)(a - b)
Step-by-step explanation:
Assuming you require the expression to be factored
Given
a² + ab - b² ← factor out from each term
= (a² + ab - 2b²) ← factor the quadratic
Consider the factors of the coefficient of the b² term(- 2) which sum to give the coefficient of the ab- term (+ 1)
The factors are + 2 and - 1, since
2 × - 1 = - 2 and 2 - 1 = + 1, thus
a² + ab - 2b² = (a + 2b)(a - b) and
a² + ab - b² = (a + 2b)(a - b)
Answer:
1/2
Step-by-step explanation:
1/4÷1/2
1/4*2/1
2/4
1/2
Points to remember:if u change dividion sign into multiplication sign do it's reciprocal.
-/7? imagine that there is an -1 as the numerator. so now -/7 turns into -1/7
