Explanation / when you multiply 7 by -9 you get -63
Answer: .97
Step-by-step explanation:
Answer:
The solution set is (-20/9, -95/9)
Step-by-step explanation:
To solve using the substitution method, start by solving the second equation for y.
1/3y = 7/3x + 5/3
y = 7x + 5
Now that we have this, we can plug it in for y in the first equation. Then we can solve for x.
-4x - 2(7x + 5) = 30
-4x - 14x - 10 = 30
-18x - 10 = 30
-18x = 40
x = -20/9
Now that we have the value of x, we can solve for y by inputting the x value into either equation.
-4x - 2y = 30
-4(-20/9) - 2y = 30
80/9 - 2y = 30
80/9 - 2y = 270/9
-2y = 190/9
y = -95/9
Answer:
h = 11/9 or 1 2/9
Step-by-step explanation:
(-5/11)h+(7/9)=(2/9)
(-5/11)h=(2/9)-(7/9)
(-5/11)h=(-5/9)
h = (-5/9)(-11/5)
h = 11/9
or
h = 1 2/9
Yes becuase the x value is always the independent variable while R is dependent of that variable
therefore if 1 is the x and the graph is linear (a straight line) than it would be the unit rate of the situation/graph
