Answer:
She has 60% of money left.
Step-by-step explanation:
You have to find out how much Php that Lei has left :
Php 150 - Php 48 - Php 12 = Php 90
She has a remaining of Php 90. Next, you have to find the percentage by dividing hy original amount and then, multiply by 100 :
(90/150)×100 = (3/5)×100 = 60%
A constant can either shift the graph up or down. If coefficient is less than 1 it will make the graph wider, if it's more than 1 it will make graph more narrow
Answer:
y=-2x+8
Step-by-step explanation:
Evaluate the slope:
(8-0)/(0-4)= 
Find the Y-intercept:
y=8 $=c$ when x=0
Using the form: $y=mx+c$, we have the equation as:
$y=-2x+8$
To graph a slope, first you should get the equation into y-intercept form (y=mx+b) m is the slope and b is the y-intercept. When graphing, a person would vertically (up or down depending whether or not b is positive or negative). Slope is diagonal in most cases. If slope is positive then the line should move up going left to right, and if it is negative the line should move downward. I always remember slope by thinking to get to the elevator then move up or down. An example would be if the equation is y=2x-1. I would start at y-intercept. In this case it would be (0,-1), then I would move right 1 and up 2 because slope is technically 2/1. The new point would be (1, 1). Keep doing the step with slope until you have enough points to draw a line through the points. I hope I was able to help you.
