5x+8=4(3x+9) 5x+8=12x+36. 5x=12x+28
-7x=28. Divide both sides by -7 so x=-4
4y+8=4(2y-5). 4y+8=8y-20. 4y=8y-28
-4y=-28. Divide both sides by -4 so y=7
Is 495 just multiply 5 by 45 and then sum 6 by 45
No because the number 7 repeats no x-values can repeat.
1.
Use this rule: √ab = √a√b
√12√x^2
Simplify √12 to 2√3
2√3√x^2
Simplify √x^2 to x
2√3x^2
3.
Multiply the numerator and denominator by the conjugate.
2√x/x
Slope is rise/run
to find it we do (y1-y2)/(x1-x2)
y1 means the 1st y and y2 means the second y
in (x,y) form
y1=4
y2=4
x1=10
x2=7
(4-4)/(10-7)=0/3=0
slope is 0
