Slope~formula = (y_2-y_1)/(x_2-x_1) = (-1 (1)/(2)- (1)/(2) )/(2 (1)/(2)-\left ( -(1)/(2) \right) ) = (-2)/(2 (1)/(2) + (1)/(2) ) = (-2)/(3) =\boxed {- (2)/(3) }

Andre received $60 for his birthday and put it in his piggy bank. Each week, he puts 3 more dollars in his bank. The amount of money in dollars D in his bank is given by D = 3w + 60 where w is the number of weeks he has saved 3 dollars. His sister Lana makes a table of reasonable values for w. Lana selects 42 as a value for w. What is the corresponding table entry for D?(TEACHER HINT: They are asking what D will be if w is 42.)

A.54
B.105
C.186
D. 402

I Don't Get Algebra At All ._.

Answers

The answer is 186. You replace 42 where (W) is then 3X42 gives you 126. Then add 60 and get 186. D=186
The answer is C. What you do is 3 times 42 (W=42) then that will be 126 then just add 60 and D=186

Write the resultant of the two vectors as an ordered pair. <3, 6> and <5, –5>

Answers

Answer: The resultant of the two vectors as an ordered pair is given by

<8,1>

Step-by-step explanation:

Since we have given that

There are two vectors :

\vec{a}=<3,6>=3\hat{i}+6\hat{j}\n\n\vec{b}=<5,-5>=5\hat{i}-5\hat{j}

So, we need to find the "Resultant of the two vectors":

\vec{a}+\vec{b}=(3+5)\ha{i}+(6-5)\hat{j}\n\n\vec{a}+\vec{b}=8\hat{i}+\hat{j}

Hence, the resultant of the two vectors as an ordered pair is given by
