Answer: $45
Step-by-step explanation: 10 for the hour she scrubbed the floor half of that which is 5 for the half hour she scrubbed so that would be $15, then 7.50 times 4 for the hours she dusted which would be 30, and 30 plus 15 is 45
None of these are right. the only equation that works id y=17x-76
Answer:
36,42,102
Step-by-step explanation:
A triangle is 180° total so your equation to find x is:
3x+6+4x+2+10x+2=180°
17x+10=180
17x=170
x=10
to find the individual sides:
3(10)+6=36
4(10)+2=42
10(10)+2=102
to make sure this is right, add 36+42+102. It should equal 180 and it does
Answer:
-16
Step-by-step explanation:
You have to start by answering the parenthesis first then continue with the question
Hello :
f(x) = <span>a(x-k)²+k....... the point vertex is (h , k )
in this exercice : h = -3 and k = -1 s0 f(x) = a(x+3)²-1
find : a
but f(0)=8
a(0+3)² -1 = 8
9a-1=8
9a =9
a=1
f(x) =(x+3)²-1 =x²+6x+9-1
f(x) = x²+6x+8 .... (</span><span>the quadratic function in standard form )</span>
