Answer:
-3
Step-by-step explanation:
If we directly evaluate the function at -1, we get 0/0, meaning we may still have a limit to find.
In this case, factoring the polynomial at the top would be helpful.
The polynomial can be factored to (x+1)(x-2), so the function would now turn out to be (x+1)(x-2)/(x+1)
The (x+1) cancel out, leaving you with (x-2), which you can directly evaluate by plugging in x as -1:
-1-2 = -3
Quick disclaimer: the function is still undefined at -1; it's just that the function gets closer and closer to -3 as you approach -1.
I hope this helped you.

What’s the answer to this question HELP ME !!
Answer:
x=6
Step-by-step explanation:
The picture is a little unclear but I hope this is true...
To find the perimeter you need to add the sides of the triangles and the question says that the perimeters of the triangles are equal. So,...
(2x+4)+(2x)+(2x+3)=(3x+1)+(2x)+(2x)
2x+4+2x+2x+3=3x+1+2x+2x
4+2x+3=3x+1
7+2x=3x+1
2x-3x=1-7
-x=-6
x=6
the question is in the picture can someone PLSSS answer!!!

Problem 1
Answer: Choice B) x = -2------------------
Explanation:
Add the equations straight down.
The x terms add to 5x+(-3x) = 2x
The y terms cancel out since 3y+(-3y) = 0y = 0
The right hand sides add to -7+3 = -3
After adding the equations you should get 2x = -4 which solves to x = -2
=====================================================
Problem 2
Answer: y = 4------------------
Explanation:
Since 5x = 0, this means x = 0 after dividing both sides by 5.
Use this to find y
y = -4x+4
y = -4(0)+4
y = 4
If you want the value of z, then
x = -3y+z+6
0 = -3(4)+z+6
0 = z-6
6 = z
z = 6
The width of a rectangle is 5 times the length. If the perimeter is 72, find the dimensions of the rectangle.

Step-by-step explanation:
if 6 members has paid, then the remaining 8 will be 8 x 12.55 = 100.4
Answer:
The answer is $100.40
Step-by-step explanation:
ok. their are 14 members. 6 members payed their dues in week 1. so, subtract 6 from 14. 14 - 6 = 8. Now, the due is $12.55. 8 members payed their dues in week 2, so multiply 8 by 12.55. 8 x 12.55 = 100.50 the answer SHOULD be $100.50 i would think, but there is not an option for that. so, i would pick option 4, because that is .10 off from 100.50. Good luck!!

Please help me i don’t understand it :(
Answer:
Step-by-step explanation:
Explaining the Basic Concept:
This is a piecewise function, which means that it is made up of several different functions which all have different domains
In this question, we have 3 'pieces' in our piecewise function
the domain of each piece is:
1. x < -1
2. -1 ≤ x ≤ 2
3. x > 2
we will use the function related with the respective domain
Finding the values of the function:
h(-4)
Here, our input value is -4
we notice that -4 is in part of the first domain
therefore, -4 is in the domain of the first function
So, we will use the first function
h(x) = -(x/4) + 2 (for x < -1)
replacing x with -4
h(-4) = -(-4/4) + 2
h(-4) = 1 + 2
h(-4) = 3
h(1):
Here, our input value is 1
we notice that 1 is a part of the second domain
Hence, 1 is in the domain of the second function
So, we will use the second function
h(x) = -(x-1)² + 2 (for -1 ≤ x ≤ 2)
replacing x with 1
h(1) = -(1-1)² + 2
h(1) = -(0)² + 2
h(1) = 2
h(2):
Here, out input value is 2
We notice that 2 is a part of the second domain
Hence, 2 is a part of the domain of the second function
So, we will use the second function
h(x) = -(x-1)² + 2 (for -1 ≤ x ≤ 2)
replacing x with 2
h(2) = -(2-1)² + 2
h(2) = -(1)² + 2
h(2) = - 1 + 2
h(2) = 1
Therefore:
h(-4) = 3
h(1) = 2
h(2) = 1
which of the following describes controlled variables
A what you change for testing
B what you keep the same
C what you measure
Answer:
b, controlled variables are constant and unchanged
A controlled variable is what is held constant. When doing an experiment, it is ideal to only focus on one variable at a time while keeping everything else in check. This way you can compare two items effectively.
In contrast, a manipulated variable is one that is intentionally changed to see how it affects the subject. For example, if you're testing various fertilizers, then the fertilizer brand would be the manipulated variable. The soil, moisture, amount of sunlight, and other environmental factors are kept the same (each subject gets the same about of each) making them to be controlled variables.
What is the prime number?
Answer:
In math, prime numbers are whole numbers greater than 1, which have only two factors – 1 and the number itself. Prime numbers are divisible only by the number 1 or itself. For example, 2, 3, 5, 7, and 11 are the first few prime numbers.

Write an equation in slope-intercept form for this line.
Answer:
y = -5/4x -19
Step-by-step explanation:
It is often convenient to simplify a point-slope form of the equation.
y = m(x -h) +k . . . . . line with slope m through (h, k)
y = -5/4(x -(-8)) -9 . . . . fill in given values
y = -5/4x -10 -9
