Answer:
Step-by-step explanation:
If the given is x^2 then the degree is 2.
Degree: 4 - x^2 = 2.
It is what is on the x to the highest power. If the question was
x^3 - 3x^2 + 2x + 4
The the degree would be 3
Answer:
I am literally dying from boredom because of quarantine
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
y = 8x − 9
y = 4x − 1
Since the two equations are both equal to y set them equal to each other
8x -9 = 4x-1
Subtract 4x from each side
8x - 9 -4x = 4x-1-4x
4x -9 = -1
Add 9 to each side
4x-9+9 = -1+9
4x = 8
Divide by 4
4x/4 = 8/4
x=2
Now find y
y =4x-1
y = 4(2) -1
y = 8-1
y = 7
(2,7)
The solution to the system of equations is where the two lines intersect. When the two lines are graphed, they will intersect at (2,7)
Answer:
The graph in the attached figure
Step-by-step explanation:
Graph the solution of the inequality

we know that
The solution is the interval ---> (-∞,-4]
All real numbers less than or equal to -4
In a number line the solution is the shaded area at left of t=-4 (closed circle, because the number -4 is included in the solution))
using a graphing tool
