In order to utilize the graph, first you have to distinguish which graph accurately pertains to the two functions.
This can be done by rewriting the equations in the form y = mx + b which can be graphed with ease; where m is the slope and b is the y intercept.
-x^2 + y = 1
y = x^2 + 1
So this will be a basic y = x^2 parabola where the center intercepts on the y axis at (0, 1)
-x + y = 2
y = x +2
So this will be a basic y = x linear where the y intercept is on the y axis at (0, 2)
The choice which depicts these two graphs correctly is the first choice. The method to find the solutions to the system of equations by using the graph is by determining the x coordinate of the points where the two graphed equations intersect.
Answer:
no real answer
Step-by-step explanation:
distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r
then we have 7-3r=-8-3r
from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.
since 7 doesn't equal -8, there is no answer.
if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers
Answer:
It will cost $72 Justice to fence in his garden.
Step-by-step explanation:
Total length of the fencing around the garden = 24 feet
Cost of fencing per inch = $0.25
Now, as we know 1 foot = 12 inches
⇒ 24 feet = 24 x 12 inch = 288 inches
⇒ 24 feet = 288 inches
Hence, the total length of fencing = 288 inches.
Now, Total cost of Fencing
=Total length of fencing x Cost of fencing par inch
= 288 inches x ($0.25)
= $ 72
or, the total cost of fencing = $72
Hence, it will cost $72 Justice to fence in his garden.
