Answer:
Each piece of ribbon lengths 2.55 feet.
Step-by-step explanation:
A 30-foot piece of ribbon that Elena has cut for a craft project. Then she cuts off 7 feet from this.
So, the remaining length of the ribbon for the craft project will be (30 - 7) = 23 feet.
Now, then she cuts the remaining piece into 9 equal lengths of feet each.
Hence, each piece of ribbon lengths 
feet. (Answer)
Point slope form again
-3-9/3+1= -3
y+1=-3(x-9)
y+1=-3x+27
y=-3x+26
5+1/2+1=2
y+1=2(x+1)
y+1=2x+2
y=2x+1
For your system of equations you have
y={y=-3x+26}
y={y=2x+1}
There is a couple ways you can solve this. You could either use a subtraction method, or a substitution method. since they are both y = something i would just substitute one y in one or the other equation.
2x+1=-3x+26
5x+1=26
5x=25
x=5
So now you just plug in x = 5 for each quotation and you have your y's for both solution points
y=-3(5)+26
y=11
y=2(5)+1
y=11
So this works out nice, your solutions for the set of equations is (5,11) since they are the same points
Answer:
1. 0
Step-by-step explanation:
I don't know the even number one. (−1)^r when r is an odd integer greater than 1 always will equal -1 then -1 + 1 = zero
Answer:
-2
Step-by-step explanation:
slope = difference of y/difference of x
slope = (-6 - 16) / (-7 - -18) = -22/11 = -2
