Hello,

Do you mean
h(x)=2x+5
g(x)=8-3x

h(g(x))=h(8-3x)=2(8-3x)+5=16-6x+5=21-6x

h(g(1.5))=h(g(3/2))=21-6*3/2=21-9=12

$\large\bf{\underline{Given :}}$

An isosceles triangle ABC
AD is a bisector of ∠‎A

__________________________________________

$\large\bf{\underline{To \:prove :}}$

BD = DC

__________________________________________

$\large\bf{\underline{In \: triangle \: ABD\:and\: triangle\:ADC}}$

${⟹AD = AD\:\:\:\:\:\:\:\:\:\:\:\:\:\:( common)}$

${⟹∠BAD = ∠CAD\:\:\:\:\:\:\:\:\:( given : AD \:is \:bisector \:of \:∠A )}$

${⟹∠ABD = ∠ACD\:\:\:\:\:\:\:\:\:( given : angles\: in \:isosceles\: trianlge )}$

$\large\bf{\underline{Hence}}$

By ASA criteria ∆ABD congurant to ∆ADC

__________________________________________

$\large\bf{\underline{So}}$

By CPCT ( corresponding parts of congurant triangle )

$\large\bf{BD = DC}$

Does -2(z+3)-z=-z-4(z+2) have one,zero or infinite solutions

Andrew [12]

Hello from MrBillDoesMath!

Answer:

One solution (z = -1)

Discussion:

-2(z+3)-z=-z-4(z+2) =>

-2z -6 -z = -z -4z - 8 =>

-3z -6 = -5z -8 => add 6 to both sides

-2z = -5z -2 => add 5z to both sides

3z = -5z +5z -3 =>

3z = -3 =>

z = -1

Thank you,
