Answer:
k = 5
Step-by-step explanation:
Given
+ 
= 3 ( multiply through by 3 to clear the fractions )
k + 1 = 6 ( subtract 1 from both sides )
k = 5
Percent decrease = (change in value) / (original value)
change in value = 9965-10100 =-135
We will just use 135 because the negative just that the value decreased
original value = 10100
So 135 / 10100 = .0134
This is a decrease of 1.34%
Y intercept is (0,-7). slope is 2.
Change the function to y=mx+b format first. m=slope and plug in 0 as x to get y intercept.
The value of x would be 60 degrees
explanation
===============================
the triangle has one missing angle that would be congruent to x since they are corresponding angles which means they are congruent.
We know that the triangle has to add up to 180 degrees. We add the 2 angles and get 120 degrees. We subtract 120 degrees from 180 to find the 3rd missing angle that is congruent to x degrees. 180-120=60 degrees. If 60 degrees is corresponding to x degrees, therefore, x should be equal to 60 degrees.
Hope this helps :)
Answer:
the price is 250
Step-by-step explanation:
let cp be x.
the marked price is 116x/100=1.16x.
25x/100=6250/100
x=250
