Hey there! :)
y = 3/4x - 2
To find the slope and y-intercept, simply use slope-intercept form to understand this.
Slope-intercept form is : y = mx + b ; where m = slope, b = y-intercept.
Therefore, you must ask yourself : which value is in the "m" spot and which value is in the "b" spot in our given equation?
Using this logic, we can come to the conclusion that :
Slope = 3/4 & Y-intercept = -2
~Hope I helped! :)
Suppose
At the same time, we can write
Note that 
(just reverse the sum). Let's pair the first terms of 
and 
, and the second, and the third, and so on:
Now, each grouped term in the sum on the right side adds to 151. There are 52 grouped terms on that same side (because there are 50 numbers in the range of integers 51-100, plus 50 and 101), which menas
But , as we pointed out, so
60% of 20 is (0.6 x 20) = 12 passes
There are a further 30 quizzes remaining (50 total during the year minus 20 already written)
80% of 30 is (0.8 x 30) = 24 passes
The student has passed (12 + 24) = 36 quizzes out of 50 total, giving an overall pass percentage of ((36 / 50) x 100)) = 72%.
Move all the x terms to one side and solve for x. 15x-10x=21-6 : 5x/5=15/5 : x=3
Answer:
2S + J = 24000
Step-by-step explanation:
let Susan be S
let Jinan be J
they paid 24000
susan paid twice as muh as jinan did
2S + J = 24000
therefore equation is
2S + J = 24000
