6x^2=12x-20
26x=12x-20
14x=-20
x= -1.4285714286
or x= -1.43. simplify to the hundredths place
The relation maps a unique output value to each input value. It is a function.
Note that Cheryl wants to find the number of hours <u>seventh grade boys and girls</u> spend on homework each week.
There are multiple causes of a biased sample. Two of the most obvious ones I find are:
1. She's surveying <u>girls</u>, but she is trying to get data on the number of hours <em>all</em> seventh graders (boys <em>and</em> girls) spend.
2. She's surveying 50 girls from the <u>entire school</u>, although she is trying to get data on seventh graders only.
Answer:
first you need to make that into an equation here i think your equation that will help you on that question is 46°+63°=X
Step-by-step explanation:
K-is (4°k+5°y)+(4°k+10°y)=118°
and then what ever you get out of the K's and Y's you will divide that number by 118 and that is the value of K
and this is my opinion
Answer:
1. (x+2y)^2-ab x^2+4xy+4y^2-ab
2. 3n-13<9 n<22/3
3. 6+n/7=4 n/7=-2
