Answer:
y= -1/23
Step-by-step explanation:
The equation y(5)-4y(4)+4y(3)=1 can be solved thus:
Work on brackets first:
5y-16y+12y=1
Add up y values
5y-28y=1
Divide both sides of equation
-23y=1
y=1/-23
Therefore the value of y is -1/23
A if a parallelogram is not a rectangle then it doesnt have congruent diagonals
Answer:
-2x-7y=-4
Step-by-step explanation:
We want to add the two expressions
First we add the Left Hand Sides and do the same to the Right Hand Sides. This gives us:
(5x-9y)+(-7x+2y)= 1 +( -5)
Open the brackets
5x-9y-7x+2y=1-5
Regroup like terms
5x-7x-9y+2y=-4
-2x-7y=-4
The result of adding the two given expressions is -2x-7y=-4.
Answer d is the right one;(
Answer:the relative ages of the rocks exposed in the circle cliff area are given below.
1. older rocks are exposed in the center and younger rocks in the flanking flatirons.
2. younger rocks are exposed in the center and older rocks in the flanking flatirons.
Step-by-step explanation: this is because whenever older rocks are exposed in circle cliffs, exposure occur at the center while younger rocks will be exposed in the flanking flatirons at this time.
2. But when younger rocks are exposed in contrast to the older rocks, these younger rocks are exposed at the center while the older ones receive exposure at the flanking flatirons.
Note that both cases interchange, exposure of a particular rock occur at the center and the next category of rock receive theirs at flanking flatirons.
