Common factor of which term?
I do see that the 1st term can be re-written as (3x)y^2, so (?) is y^2.
We can rearrange the initial equation to y=mx+b
y=2x-5
Since perpendicular slopes must equal -1,
x=the perpendicular slope
2x=-1
x=-1/2
(Or you can just take the negative reciprocal above is just the "formula form" for it)
Therefore, the perpendicular slope is -1/2
Answer:
The length of BC = 28 units
Step-by-step explanation:
* In triangle ABC
∵ Angles B and C are congruent
∴ m∠B = m∠C
* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length
∴ AB = AC
∵ AB = 4x - 7
∵ AC = 2x + 7
∴ 4x - 7 = 2x + 7 ⇒ collect like terms
∴ 4x - 2x = 7 + 7
∴ 2x = 14 ⇒ divide both sides by 2
∴ x = 14 ÷ 2 = 7
* Now we can find the length of BC
∵ The length of BC = 4x ⇒ substitute the value of x
∴ The length of BC = 4 × 7 = 28 units
Answer: x-3
Step-by-step explanation:
Answer: x-3. Step-by-step explanation: f(x) = 3x-2 . g(x) = 2x + 1 (f-g)(x) = 3x-2 - ( 2x+1) Distribute the minus sign =3x-2 -2x-1. Combine like terms
Hope this helps
