For what value of k does the equation 6(x + 1) + 2 = 3(k5x + 1) + 3 have no solution?
Answers
Answer:
k = (6/15)
Step-by-step explanation:
The equation is:
6*(x + 1) + 2 = 3*(k*5*x + 1) + 3
To have no solutions, we need to have something like:
x + 7 = x + 4
where we can remove x in both sides and end with
7 = 4
So this equation is false, meaning that there is no value of x such that this equation is true, then the equation has no solutions.
First, let's try to simplify our equation:
6*(x + 1) + 2 = 3*(k*5*x + 1) + 3
6*x + 6 + 2 = 3*k*5*x + 3*1 + 3
6*x + 8 = 15*k*x + 6
if 15*k = 6, then the system clerly has no solution.
then:
k = 6/15
then we get:
6*x + 8 = (6/15)*15*x + 6
6*x + 8 = 6*x + 6
8 = 6
The system has no solutions.

Answer:
-x + 5y = 12
Step-by-step explanation:
Eliminate the fractional coefficient by multiplying both sides by 5:
5y - 15 = x - 3
Combine the constants: 5y = x + 12
Subtract x from both sides: -x + 5y = 12 This is in standard form

Answer:
eric=12
bill=16
Step-by-step explanation:
you can solve this using two simple algebraic equations. this is the key I will be using:
x=bill
y=Eric
x+y=28
x=y+4
since x is by itself in the second equation, I can replace the x in the first equation with y+4
(y+4)+y=28
subtract 4 from both sides
y+y=24
which is also 2y=24
divide both sides by two.
y=12
so now we know Eric is 12 years old.
using this, we can replace the "y" in the second original equation (x=y+4)
x=12+4
x=16
Bill is 16 years old.

Step-by-step explanation:
The interest formula is ...
I = Prt . . . . interest rate r on principal P for t years
We can fill in the known values and solve for t.
60 = 750·0.04·t
60/30 = t = 2
The loan was repaid in 2 years.

Answers
Answer:
these are tough, it takes a lot of practice to get used to these, sooo
Step-by-step explanation:
we know the slope, m= -5/3, and we're given a point so use the point slope formula
y= mx + b
the point we are given is in this form (x,y)
then plug the information into our point slope formula
y = (-5/3) x + (-2)
y = -5x/3 -2

“B” is the y-intercept when x = 0. They give this in the table as “-2” so b = -2
Find slope (m) = (-8)-(-2)/(-2)-0 = 3
Equation A is y = 3x - 2 (y = mx + b)
Equation B find “m” and “b”:
Find m = (-9)-(-5)/(-3)-(-1) = 2
To find be, plug in m, x, and y from ANY coordinates in table b into y = mx + b:
-9 = 2(-3) + b
-9 = -6 + b
b = -3
Equation b is y = 2x -3
Use substitution and substitute all of equation “b” for “y” in equation a:
2x - 3 = 3x - 2
Algebra: x = -1
Plug back into equation a:
y = 3(-1) -2
y = -5
x = -1
(-1, -5) final answer (B)

Three corners of a city bloc is located at (2,2) (2,-4) (-5,-4) on a coordinate plane what are the coordinates of the fourth corner
Answers
Answer:
(-5, 2)
Step-by-step explanation:
Three corners of a rectangular city block are located at (2,2), (2,-4) and (-5,-4) on a coordinate plane. What are the coordinates of the fourth Coordinate?
Solution:
A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. Also, all the angles are at 90 degrees.
Since the city block is rectangular in shape, therefore the fourth coordinate would have the same y coordinate as the point (2, 2) and it would also have the same x coordinate as (-5, -4).
Hence the fourth coordinate is (-5, 2)
