A student received a coupon for 11% off the total purchase price at a clothing store. Let z be the original price of the purchase. Use the expression below for the new price of the purchase. Write an
equivalent expression by combining like terms.
Z-0.112
Z-0.117=

  0.89z

Think of it like 100% - 11% = 89%

You save 11%, so you need to pay the remaining 89%

Taking 89% of z then leads to 0.89z

So that's why z - 0.11z = 0.89z

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

f(x)=2/3x-8, which give g(x) the greatest value.
