Hiya. I'm going to rewrite the second equation.
By subtracting 5x by both sides, I'll be able to have y by itself:
-y=-5x+13
I'm going to then divide both sides by -1 to get:
y=5x-13.
Then, I'm going to plug that equation into the first equation
3x+2(5x-13)=39
Factor:
3x+10x-26=39
Combine like terms:
13x=65
Divide both sides by 13 to get x by itself to get x=5
Plug this back into the equation of y=5x-13
y=5(5)-13 to get y=12
Answer:
It's 13
Step-by-step explanation:
Well, just use the triangle inequality theorem and pay close attention to angles CAB and EAC... that's all I can say
Hope that helped
Answer:
y=-1/3x+4
Step-by-step explanation:
1/3x+y=4
y=4-1/3x
y=-1/3x+4
Answer:
-1
Step-by-step explanation:
The y-intercept is where the line crosses the y-axis.
