Answer:
Step-by-step explanation:
in order to solve this system of equation we would say that let
3x+2y=-8........................................................ equation 1
1 x - y = -1 ........................................................ equation 2
from equation 2
1 x - y = -1 ........................................................ equation 2
x = -1 + y....................................... equation 3
substitute for equation 3 in equation 1
3x+2y=-8........................................................ equation 1
3( -1 + y) + 2y = 8
-3 + 3y +2y = 8
collect the like terms
-3 + 5y = 8
5y = 8 + 3
5y = 11
divide both sides by the coefficient of y
5y/5 = 11/5
y = 2.2
put the value y = 2.2 into equation 3
x = -1 + y....................................... equation 3
x = -1 + 2.2
x = 1.2
therefore th value of x is 1.2 and y is 2.2
Your not wrong I don’t know why your teacher said that
Answer:
Step-by-step explanation:
We are given the following in the question:
Flat fee = 6 dollars
Charges per hour = 10 dollars per hour
Let Steve work for h hours.
Then, we can write the total charge in the following manner:
Total charge =
Putting values, we get,
is the required equation for total charges if Steve worked for h hours.
Factors are the numbers another number can be divided from. example-
8÷4=2, 4 is a factor of 8.
so the factors of 4 are 1,2and 4itself. like this-
4×1=4
1×4=4
2×2=4
answer- 1,2 and 4.
