If the slope of the line through points (3 , -2) and (1 , k) is 3/5 , find the value of k

Answers

Answer 1

Answer: Point slope formula is:
(y₂-y₁)=m(x₂-x₁)
(k - (-2) = $(3)/(5)$ (1 - 3)
k + 2 = $(3)/(5)$ (-2)
k + 2 = $- (6)/(5)$
k = -16/5 = -3 1/5

check:
$(-3.2 + 2)/(1 - 3) = (3)/(5)$

A student drops a penny from the top of a tower and decides that she will establish a coordinate system in which the direction of the penny's motion is positive. what is the sign of the acceleration of the penny?

Can someone please help me, this is my last question I have been stuck on it for 30 minThe work of a student to solve a set of equations is shown:

Equation A: y = 15 − 2z
Equation B: 2y = 3 − 4z

Step 1: −2(y) = −2(15 − 2z) [Equation A is multiplied by −2.]
2y = 3 − 4z [Equation B]
Step 2: −2y = 15 − 2z [Equation A in Step 1 is simplified.]
2y = 3 − 4z [Equation B]
Step 3: 0 = 18 − 6z [Equations in Step 2 are added.]
Step 4: 6z = 18
Step 5: z = 3

In which step did the student first make an error?
Step1
Step 2
Step 3
Step 4

Answers

step 2
he didn't distribute
what he did:
-2(15-2z)=15-2z
that is obviously false

what should have happened is
-2(15-2z)=-30+4z
then add

-2y=-30+4z
2y=4-4z
0=-26
false
no solution
inconsitient, these lines ar paralell

anyway, step 2 is error

The mistake was made in step 2. In simplifying the equation, he has to distribute the -2 through the parentheses. Step 2 simplification should be

-2y = -30 + 4z

When the 2 equations are added, the resultant equation is 0 = -27 therefore it has no solution.

How do solve 4v-13-10v=12-24v+5

Answers

You get all the v's on one side by adding 24v to both sides
4v-13-10v = 12-24v +5
+24v +24v
And then you would get
4v-13-10v+24v = 12+5
Then combine like terms
18v-13=17
Then you would get v alone by adding 13 to both sides
18v-13= 17
+13 +13
That would give you
18v=30
Then divide both sides by 18 to get your final answer
18v = 30
/18 /18
Your final answer is...
V=1.66

Answer: 1.67

Step-by-step explanation:

Collect the like terms.

4v-10v+24v = 12+5+13

This gives:

-6v+24v = 30

This gives:

18v =30

Divide both sides by 18

v = 30/18

v = 1.67

How to write g(x)=2x+3/x+1 in the form of:g(x)=a/x+p +q

Answers

Hello,

Please write correctly.

g(x)= (2x+3)/(x+1) to be written like a/(x+p) + q

It is very simple!

(2x+3)/(x+1)= [(2x+2)+1]/(x+1)= (2(x+1)+1)/(x+1)= 2+1/(x+1)
