I’m not sure what the negative fours are at the end of your problem are for, but the slope of the line passing through those points is 4.
The line itself is y = 4x - 11
The answer is 39 degrees <span />
Answer:
A)2.6x06x5x6x8,700000
B) -4.0.063,-6x2.5x10x10
Step-by-step explanation:
I'm pretty sure it's like that
so it would be 8x13/8+13, which would simplify out to be 104/8+13 which would then simplify out even more to be 104/21 as a fraction or 4.95 as a decimal
hope this helps!! :) ❤❤❤❤
Answer:
Desiree answered 40 questions correctly
Step-by-step explanation:
Let
x = number of questions answered correctly
y = number of questions unanswered
z = number of wrong answers unanswered
The system of equations can be expressed
x + y + z = 50
3*x - 0.5*y -1*z = 110
Desiree did not leave any question unanswered
This means that the equations become
y = 0
x + z = 50
3*x -z = 110
If we add them together, we get
4x = 160
x = 40
z = 10
