0=0
all real numbers are solutions
b. x-y+(-x)=x-y+(-x)
-y=-y
0=0
x=0/0 0 over 0
Answer:
<u>Length of 1 piece= Length of total divided by 8</u>
Step-by-step explanation:
Length of total= 5.24 feet long
Width of total= 1.34 feet wide
Width is divided by 1 line so, there are 2 parts.
Width= 1.34 divided by 2
Width= 0.67 feet wide
Length is divided by 7 lines, so there are 8 parts.
Length= 5.24 divided by 8
Length=0.655 feet long
They are asking for formula to find the length of each piece
<u>Length of 1 piece= Length of total divided by 8</u>
<u></u>
Hope that helps!
Answer: f(0) = 6.
Explanation:
Ther ordered pairs are: (x,y) or (x, f(x) )
So, (1,0) means that f(1) = 0 which denies the fourth choice.
(-10,2) means that f(-10) = 2 which denies the first choice
(0,6) means that f(0) = 6, which is the third choice. So, that is the true equation.
Answer: 5 • (2x2 - 17x - 2)
———————————————————
x - 8
Step-by-step explanation:
Step by step solution :
Step 1 :
Equation at the end of step 1 :
Step 2 :
10x2 - 85x - 10
Simplify ———————————————
x - 8
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
10x2 - 85x - 10 = 5 • (2x2 - 17x - 2)
Trying to factor by splitting the middle term
3.2 Factoring 2x2 - 17x - 2
The first term is, 2x2 its coefficient is 2 .
The middle term is, -17x its coefficient is -17 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -17 .
-4 + 1 = -3
-2 + 2 = 0
-1 + 4 = 3
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Answer:
Step-by-step explanation:
No. Of miles Yelina plan to run =5.6 miles
No. Of miles Yelina ran today = 3.1 miles
So we have to minus both the no.
=2.5 miles
Thus 2.5 miles left for her to run today
