Which of these functions is not a linear function? Why?
f(x)=x-x
f(x)=3x
f(x)=x3
f(x)=23x-2
how am i supposed to know-
Answer:
f(x)=x3
Step-by-step explanation:
If you meant f(x)=x3 by f(x)=x^3 then that would be a cubic equation and not linear?

Answer:
x=92
Step-by-step explanation:
those to angles are supplementary meaning that they add up to equal 180
so you set up the equation 180=x+x-4
180=2x-4
step 1 add 4 to each side
184=2x
step 2 divide each side by 2
x=92
so the angles equal 92 and 88
Answer:
92°
Step-by-step explanation:
180 degrees on a straight line.
2x - 4 = 180
2x = 184
X = 92°

9x+6+45=100
Answer:
9x+6+45=100
Transposing (45) to RHS
= 9x+6=100-45
= 9x6=55
Now, transposing (6) to RHS
= 9x=55-6
= 9x=49
Now, transposing (9) to RHS
= x=49÷9
= x=5.44.....
Therefore, value of x=5.44..............

In order to find the value of x, we can write the following statements and reasons:
Triangle PQR:
1. Statement: PS = PS
Reason: Reflexive property of equality
2. Statement: angle PSQ is congruent to angle PSR
Reason: Given
3. Statement: SQ is equal to SR
Reason: Given:
4. Statement: Triangle PSQ is congruent to triangle PSR
Reason: Case SAS of congruency
5. Statement: PQ is congruent to PR, so PR = 8
Reason: Corresponding sides of congruent triangles
Quadrilateral VSTU:
1. Statement: VT = VT
Reason: Reflexive property of equality
2. Statement: angle SVT is congruent to angle UVT
Reason: Given
3. Statement: angle VST is congruent to angle VUT
Reason: Given
4. Statement: Triangle VST is congruent to triangle VUT
Reason: Case AAS of congruency
5. Statement: ST = TU
Reason: Corresponding sides of congruent triangles
So we have 5z = 2z + 3. Solving for z, we have z = 1, so ST = 5z = 5
factorise: x^{2} -49
Answer:
[tex] {x}^{2} - 49 = 0 \\ {x}^{2} = 49 \\ x = \sqrt{49} \\ x = 7[/tex]

2. rectangle with length (x+3) and width 7
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle?
Answer:
1= Perimeter =9.6
Area = 5.76m^2
Answer:
find the perimeter and area:
1. square with a side 2.4 m in length find the perimeter and area
answer:
length [l]=2.4m
area of square=l²=2.4²=5.76m²
perimeter of square=4l=4×2.4=9.6m
2. rectangle with length (x+3) and width 7
answer:
length [l]=x+3
Breadth [b]=7
perimeter of rectangle =2{l+b}=2(x+3+7)=2x+20
area of rectangle=l×b=(x+3)×7=7x+21
3. although a circle does not have sides, it does have a perimeter. what is the term for the perimeter of a circle.
answer:
the term for the perimeter of a circle=2πr (when radius is given ) and πd (when diameter Is given)

Fabiola's special seasoning mix has three ingredients. The recipe uses 4 parts thyme, 3 parts parsley, and 1 part green onion. If she is making 24 tbsp. of the mix, how many tbsp. of parsley does she need?
3
5
15
9
Answer: 9
Step-by-step explanation: First, you find how many parts are needed. 4+3+1=8
So, we then divide 24 by 8 to find out what one part is. This is 3
As she needs 3 parts of parsley, we multiply 3 by 3 (each part) to get 9 tbsp.
Fabiola's special seasoning mix of 24 tbsp. needs 9 tbsp. of parsley.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, Fabiola's special seasoning mix has three ingredients. The recipe uses 4 parts thyme, 3 parts parsley, and 1 part green onion.
Let, 'x' be the ratio multiplier.
Therefore, 4x + 3x + x = 24.
8x = 24.
x = 3.
So, She needs 3×3 = 9 tbsp. of parsley.

B. ~240°

Step-by-step explanation:
24 is 3/4% of what number
Answer:
32
Step-by-step explanation:
Alright, so think of the "what number" as x in this case. (Or any number/symbol you choose.)
So our simple equation looks something like this:
[tex]24= x *\frac{3}{4}[/tex]
So, to find out what the "what number" would be we'd flip the fraction around/find the reciprocal and multiply 24 by it. That gives us "x" or the number we're missing.
So: [tex]24 * \frac{4}{3} = x[/tex]
Doing the simple math we get:
[tex]24 * \frac{4}{3} = 32[/tex].
32 is your answer.
Hope this helps and have a nice day! Sorry I'm not great at explaining it!

Graph the relation. Is the relation a function? Why or why not?
{(-5, 6), (-2, 3), (3, 2), (6, 4)}
Yes; there is only one domain value for each range value.
Yes; there is only one range value for each domain value.
No; a domain value has two range values.
No; a range value has two domain values.
Answer:
Yes; there is only one range value for each domain value.
Step-by-step explanation:
For a relation to be a function, every input, x-value, needs to have a unique output, y-value. This means that one x-value cannot have multiple y-values. So, in a function x-values will never repeat. Since x-values do not repeat in this relation, it is a function.

y = 2x - 4
x + 2y = 12
Answer:
algebraically.
y = 2x - 4........….....(1)
x + 2y = 12..............(2)
substituting the value of y in equation (2) we get
x+2(2x - 4)=12
x+4x-8=12
5x=12+8
x=20/5=4
substituting the value of x in equation(1) we get
y=2×4-4=8-4=4
:.(x,y)=(4,4)answer
The value of x = 4
The value of y = 4
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be = A
Let the second equation be = B
Now ,
y = 2x -4
Subtracting 2x on both sides , we get
y - 2x = -4 be equation (1)
And ,
x + 2y = 12 be equation (2)
Now , on simplifying the two equations , we get
Multiply equation (1) by 2 , we get
2y - 4x = -8 be equation (3)
Now , subtract equation (3) from equation (2) , we get
5x = 20
Divide by 5 on both sides , we get
x = 4
Therefore , the value of x is 4
Substitute the value of x in equation (2) , we get
4 + 2y = 12
Subtracting 4 on both sides , we get
2y = 8
Divide by 2 on both sides , we get
y = 4
Therefore , the value of y is 4
Hence , The value of x and y is 4

can someone plz help me
Answer:
I believe D is the answer
Step-by-step explanation:
how I find the slope it by looking at the y-axis and what hits directly on that line. you can see that 3 hits directly on that line so the b in y=mx+b is three which is your starting point. then you follow the line and see where it hits directly on a point. then count the blocks. remember that it's rise over run so that's y over x. so you go down five and over one. since you go down five it's negative. the negative is only added onto the five not the one. and since it's five over one, you don't need to put the over one, it's just automatically there. hope this helps! good luck!
