f(x)=x/3+4 where f(-9)

First you substitute

f(-9)=-9/3+4

Then you solve by doing -9/3

f(-9)=-3+4

Then finish solving

f(-9)=1


So the final answer is D. 1

A builder needs to cover 10 square yards of floor with tile. red tile costs $60 per square yard, and white tole costs $40 per sq
dsp73

Answer:40 square yards

Step-by-step explanation:

Given

Floor area A=10 square yards

Red tile costs \$ 60 per square yards

White tile costs \$40 per square yards

Total money spent=\$480 on tiles

Suppose red tiles cover an area of x square yards

So, we can write

60\times x+40\times (10-x)=480\\60x+400-40x=480\\20x=80\\x=40\ \text{square yards}

Red tiles cover an area of 40 square yards

I NEED THIS ASAP please. can someone please answer this question i put the picture its on Simplify Expressions im giving 15 poin
kakasveta [241]

Answer:

in step 4

Step-by-step explanation:

we have

0.5(-12c+6)-3(c+4)+10(c-5)\\\\step1=-12c(0.5)+6(0.5)-3(c+4)+10(c-5)\\\\=-6c+3-3(c+4)+10(c-5)\\\\

so step 1 is correct

step 2

-6c+3-3(c+4)+10(c-5)\\\\=-6c+3+c(-3)+4(-3)+10(c-5)\\\\=-6c+3-3c-12+10(c-5)

so step 2 is correct

step 3

-6c+3-3c-12+10(c-5)\\\\=-6c+3-3c-12+c(10)-5(10)\\\\=-6c+3-3c-12+10c-50

so step 3 is correct

step 4

-6c+3-3c-12+10c-50\\\\=(-6c-3c+10c)+(3-12-50)\\\\=(-6-3+10)c+(-9-50)\\\\=(-9+10)c-59\\\\=c-59

so step 4 is incorrect
