Answer:
m∠CBD=68
Step-by-step explanation:
BA ⊥ BD
m∠ABD=90°
So m∠CBD+m∠ABC=90
(4x+52)+(8x-10)=90
12x=48
x=4
m∠CBD= 4(4)+52
=<u>68 </u>

Answer:
-7
Step-by-step explanation:
-9x-3=60
add 3 to each side to cancel -3
-9x-3+3=60+3
simplify
-9x=63
divide by -9 to cancel the -9
-9x/-9=63/-9
simplify
x=-7
That equation has no graph. If it had a solution, the solution would be a single number. But that particular equation has no solution either ... there is no number that 'x' could be that would make the equation true.
