Answer:
D) ,
Step-by-step explanation:
The blue boundary line has a y-intercept of 2 and a slope of 2.
It has equation :
Since the boundary line is not solid and the lower half plane of this line is shaded, its inequality is
The blue boundary line passes through the origin and has slope .
Its equation is
Since the boundary line is not solid and the right half-plane is shaded, its inequality is
The correct choice is D.
Answer: (-2,5)
Step 1: Rewrite equations
-3x+2y=16
x-2y=-12
Step 2: Changing the second equation
With substitution, you have to already have the equation to solve for the specific variable (ex: x=y+1;y=x+1). Since the equation doesn’t give us one, we can flip the second equation to give us this.
Let’s add 2y on both sides.
x-2y=-12
+2y +2y
_________
x=2y-12
Now we have the equation to solve for x!
Step 3: Substituting
Now we need to substitute x into the first equation. Let’s do this now.
-3(2y-12)+2y=16
Step 4: Solving for y
-3(2y-12)+2y=16
*distribute*
-6y+36+2y=16
*combine like terms*
-4y+36=16
*subtract 36 on both sides*
-4y=-20
*divide both numbers by -4*
y=5
This is y! Now we need to solve for x.
Step 5: Solving for x
To find x, let’s just substitute y into the equation and solve
x=2y-12
x=2(5)-12
x=10-12
x=-2
Step 6: Ordered pair
(X,y) —> (-2,5)
This is your answer! Hope this helps comment below for more questions :)
ok that is easy but it is sideways so I cant read it well I am dislexic
For the first one, it would be a mile every half hour, or a mile and a half every hour. The second one would be 1 mile every twenty minutes. I think it would be safe to say an 1 hour and a half or answer choice "D" for this problem.
Let me now if I can be more of an assistance!
Hello!
1. What is the degree of the monomial 4x^6 A. 4B. 10C. 6D. 24
The answer is C.6 because it is to the 6th power
2. What is the degree of the monomial?5A. 0B.1C. -1D. 5
The answer is B. 1
Hope I helped!
