Answer: X=2 and 3 = -1
Step-by-step explanation:Here we will use elimination method to solve the given system of an equation.
We have,
3x+y=5................equation 1
x−2y=4..................equation 2
Note: here we have unequal coefficient for both x and y. So we will first make coefficient of either x or y equal.
Here we well make coefficient of y equal by multiplying equation 1 by 2, we get
6x+2y=10..........equation 3
Now, we have coefficient of y equal with opposite sign, hence it can be eliminated on addition.
Adding equation 2 and 3, we get
x−2y=4
6x+2y=10
−−−−−
7x=14
Now divide both side by 7, we get
or, x=147=2
Plug the value of x= 2 in equation 1, we get
3X2+y=5
or, 6+y=5
Subtract 6 on both side, we get
or, y=5−6
Answer:
x^2+6x+5
Step-by-step explanation:
If the zeros are -1 and -5, then the equation factored is (x+1)(x+5). If you multiply that out you get x^2+6x+5.
Answer:
3/13
Step-by-step explanation:
First...
What we know
1. There is a set of 13 shapes.
2. With 2 triangles, 8 arrows, and circles.
Next...
Take the number of triangles and arrows and add them up.
2 + 8 = 10
Finally...
Convert it into the fraction 10/13 and subtract it by the total 13/13.
This results 3/13.
Answer: A,b,e
A:Each successive output is the previous output divided by 3.

Answer:
0.11
Step-by-step explanation:
It goes up by 0.2 each time because 0.5-0.3 = 0.2.
Do 0.9+0.2 to get 0.11
