Answer:

y + 2 = –3(x – 4)

y − 5 = 3(x  + 11)

y = -3x –  

y = x – 2

3x + y = 7

was it not all of them?

How to calculate the perpendicular distance from a line produced?? Thanks!!!
kykrilka [37]

Answer:d=a2+b2 ∣a(x0)+b(y0)+c∣. So given a line of the form a x + b y + c ax+by+c ax+by+c and a point ( x 0 , y 0 ) , (x_{0},y_{0}), (x0,y0), the perpendicular distance can be found by the above formula.

In one month, Juan worked 5 more hours than Carlito. Sara worked 3 times as many hours as Juan. Altogether they worked 80 hours
tamaranim1 [39]

Answer:

The answer to your question is  a) C + J + S = 80

                                                     b) C = J + 5

                                                      c) S = 45 hours

Step-by-step explanation:

a) To represent the number of hours that they work together, just add the variables and equal them to 80.

            Carlito  +  Juan  +  Sara  = 80

               C + J + S = 80                                 Equation l

b) Juan worked 5 hours more than Carlito

              Juan = Carlito + 5

                  J = C  + 5                                     Equation ll

c) Hours worked by Sara

                  S = 3J                                          Equation lll

                  C = J - 5

Substitute equation ll and lll in equation l to find J

                J - 5 + J + 3J = 80

                5J = 80 - 5

                5J = 75

                  J = 75/5

                  J = 15

-Find S

                S = 3(15)

                S = 45 hours

Indicate a general rule for the nh term of this sequence.<br> 12a, 15a, 18a, 21a, 24a,...
adelina 88 [10]

Answer:

The general rule for the nth term of this sequence will be:

a_n=3na+9a

Step-by-step explanation:

Given the sequence

12a, 15a, 18a, 21a, 24a,...

An arithmetic sequence has a constant difference 'd' and is defined by  

a_n=a_1+\left(n-1\right)d

Here,

a₁ = 12a

computing the differences of all the adjacent terms

d = 15a-12a = 3a, d = 18a-15a=3a, d=21a-18a=3a, d=24a-21a=3a

using the nth term formula

a_n=a_1+\left(n-1\right)d

substituting a₁ = 12a, d = 3a

a_n=12a+\left(n-1\right)3a

     =12a+3na-3a

     =3na+9a

Therefore, the general rule for the nth term of this sequence will be:

a_n=3na+9a

LAST ATTEMPT! MARKING AS BRAINLIEST! PLEASE <br><br> Algebra topic is on logarithms
xenn [34]

Answer:

Step-by-step explanation:

Not entirely sure about the first one, but I'll try the others:

2- log base 8 (8x) = log base 8 (8) + log base 8 (x) = 1 + log base 8 (x)

3 - log base 3 (5^x) = x log base 3 (5)

4 - log base 2 (5/x) = log base 2 (5) - log base 2 (x) = In 5 - In x

5 - log base 2 (2^x) = x log base 2 (2) = x · 1 = x
