Answer:
x = - 4, x = 6
Step-by-step explanation:
To find the x- intercepts let y = 0 , that is
- 3(x + 4)(x - 6) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 6 = 0 ⇒ x = 6
Step-by-step explanation:
25(2x) + 25(3y)
25 · (2 · x) + 25 · (3 · y)
(25 · 2) · x + (25 · 3) · y <em>Associative property </em><em>(a · b) · c = a · (b · c)</em>
(25 · 2)x + (25 · 3)y
(2 · 25)x + (3 · 25)y <em>Commutative property</em><em> a · b = b · a</em>
<em>50x + 75y</em>
The answer is 164. 5x4=20 and so on
Answer:
The Quantity 10$ per shirt represent a unit rate .
Step-by-step explanation:
Given:
There are 3 white shirts and 2 black shirts . per 10$ dollar.
To find:
Which quantities represent the unit rate ?
Solution:
Total of 5 shirts .
which means total of 50 dollar among 5 shirts.
i.e.50/5=10 dollars .
Hence each shirt causes 10 dollars or 10$ per shirt.
The Quantity 10$ per shirt represent a unit rate .
The sequence is arithmetic since the common difference that is equal
d=11-15=7-11=-4
a(n) = a1 +(n-1)d
a1=15
=
a(n) = 15+(n-1)-4
