Answer:
yes
Step-by-step explanation:
because both of them are horizontal straight lines
Answer:
D, B, F
Step-by-step explanation:
$2 each pound
x= pounds
y= total cost
1 pound= $2
the $2 : constant
the number of pounds: variable
the equation is y=2x
1 pound: $2
2 pounds: $4
4 pounds: $8
5 pounds: $10
these also could be written as coordinates
the coordinates are (1,2),(2,4),(4,8),(5,10)
Answer:
(D) -k2 + k - 13
Step-by-step explanation:
Pulling out like terms :
2.1 Pull out like factors :
-k2 + k - 13 = -1 • (k2 - k + 13)
Trying to factor by splitting the middle term
2.2 Factoring k2 - k + 13
The first term is, k2 its coefficient is 1 .
The middle term is, -k its coefficient is -1 .
The last term, "the constant", is +13
Step-1 : Multiply the coefficient of the first term by the constant 1 • 13 = 13
Step-2 : Find two factors of 13 whose sum equals the coefficient of the middle term, which is -1 .
-13 + -1 = -14
-1 + -13 = -14
1 + 13 = 14
13 + 1 = 14
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
-k2 + k - 13

Answer:
I don't know I'm sorry
Step-by-step explanation:
But you can do it I belive in you!!!!
The third angle is 60 degrees. A triangle has 180 degrees so 180-30-90=60
