Answer: y=-2x-9
Step-by-step explanation:
If ANGL is a square, then NG and LG are adjacent sides.
Adjacent sides are perpendicular. [Each angle is 90°]
The equation of line NG is 
.
By comparing it to equation in slope intercept form y=mx+c ( where , m= slope , c=y-interecpt)
slope =
Let slope of LG be <em>n</em>, then
[Product of slopes of two perpendicular line =-1]
Equation of a line passes through (a,b) and have slope m is given by :-
Equation of LG :
[In intercept form]
Answer:
rate of change: $0.35; initial value: $2.50; Equation: y= 0.35x + 2.50
Step-by-step explanation:
The rate of change is $0.35 because it's the one to change the total cost of the ice cream. If you get 3 toppings, you'll end up with 1.05 more dollars than if you had 0 toppings. And because of that, the initial value would also be $2.50, that's the minimum price you'll have to pay if you do want a sundae.
The equation is just restating all that, you start with the inital value b=$2.50, and the price will go up by 0.35 for every topping you add to the sundae.
Hope this helped :)
Answer:
(a) 3d=81
(b) 27
Step-by-step explanation:
every day, kojo write 3 pages
number of days he has written his story= d days
therefore number of pages he has written= 3d
from the final sentence,
3d= 81
<h3>(a) the equation to describe the situation: </h3><h3>3d= 81</h3>
(b) number of days kojo has been writing his story
3d= 81
dividing through by d
3d/3= 81/3
d = 27
<h3>therefore number of days = 27</h3>
Answer:
1. 2
2. -3/5
3. Undefined
Step-by-step explanation:
Using the rise over run method you get 4/2, -3/5, and then for the straight vertical line, its undefined.
