First, you would determine how much more this new weekly payment is. As we are getting a raise of .06 times our old payment, our new payment will be (old payment)+(.06*(old payment)), or more simply, 1.06 times the old payment. Multiplying this out gives us 1.06*250, or 265
Another way to do this, which is also two steps, is to multiply the old payment by .06 then add that to our old payment.
.06*250 = 15
250+15 = 265
I hope this helps!
Answer:
y=3
Step-by-step explanation:
The answer will be 144 because if u had 72 × 2 u would get 11
The answer is A since you just plug in -2for all the x’s
If a system of linear equations has exactly one solution then the slopes of both the lines should be different.
Given A system of linear equations has exactly one solution.
Linear equation is a type of equation when when plotted on the graph gives a straight line. The slope is the ratio of the vertical change to the horizontal change between two distinct points on a line.
let two equations be who have one solution
2x+3y=7
5x+6y=1
solving them
x=7-3y/2
put the value of x in second equation
5(7-3y)/2+6y=1
35-15y/2+6y=1
35-15y+12y=2
-3y=-33
y=11
put the value of y in x=7-3y/2
x=7-3*11/2
x=7-33/2
x=-26/2
x=-13.
There is only one solution which is (-13,11)
Taking equations and convert them into standard form
first
y=7/3-2/3x
second
y=1/6-5/6x
The standard form is y=a+bx where b is slope
from the above equations we can find that the slope of first equation is -2/3 and the slope of second equation is -5/6. In this way we are able to conclude that slopes should be different for one solution.
