f is correct

Step-by-step explanation:

A weak negative correlation. Correct option is E.

What is a correlation?

A correlation between two variables tells the how the first variable will change, with change in second variable.

Given,

Value of y decreases as the value of x increases and vice versa.

Also, x and y are nearly linearly related.

But, there is still some deviation in the values and are not perfectly linear.

Hence, there is a weak negative correlation between x and y.

Which equation below does NOT represent a function?

A
y = -4

B
y = x2 + 1

C
x2 + y2 = 6

D
y = 2x + 5

Answers

Answer:

C

Step-by-step explanation:

x2+y2=9 is an example of a non function because there is at least one x value with two or more y values .

The equation below does NOT represent a function is D x² + y² = 6

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) .

x² + y² = 9 is an example of a non function because there is at least one x value with two or more y values .

Now, y = 4

y = x - 4

y = x^2 - 4

Also, x² + y² = 6

This is not a function as there should be minimum one x value with two or more y values. this equation does not meet the criteria so this represent non-function.

Answer:

(0, 2 ) and (- [tex]\frac{4}{3}[/tex], [tex]\frac{2}{9}[/tex] )

Step-by-step explanation:

Given the 2 equations

2x² + 4x - y = - 2 → (1)

x² + y = 2 → (2)

subtract x² from both sides in (2)

y = 2 - x² → (3)

Substitute y = 2 - x² into (1)

2x² + 4x - (2 - x²) = - 2

2x² + 4x - 2 + x² = - 2

3x² + 4x - 2 = - 2 ( add 2 to both sides )

3x² + 4x = 0 ← in standard form

x(3x + 4) = 0 ← in factored form

Equate each factor to zero and solve for x

x = 0

3x + 4 = 0 ⇒ 3x = - 4 ⇒ x = - [tex]\frac{4}{3}[/tex]

Substitute these values into (3) for corresponding values of y

x = 0 : y = 2 - 0² = 2 - 0 = 2 ⇒ (0, 2)

x = - [tex]\frac{4}{3}[/tex] : y = 2 - (- [tex]\frac{4}{3}[/tex] )² = 2 - [tex]\frac{16}{9}[/tex] = [tex]\frac{2}{9}[/tex] ⇒ ( - [tex]\frac{4}{3}[/tex], [tex]\frac{2}{9}[/tex] )

Determine whether each number is a solution of the
given inequality.

6-n > 11
when n = -5

O YES (n = -5 is a solution of the inequality)
O NO (n = -5 is not a solution of the inequality)

Answers

Answer:

NO (n = -5 is not a solution to the inequality).

Step-by-step explanation:

Given

[tex]6-n-6>11-6[/tex]

Subtract 6 from both sides

[tex]6-n-6>11-6[/tex]

Simplify

[tex]-n>5[/tex]

Multiply both sides by -1 (reverse the inequality)

[tex]\left(-n\right)\left(-1\right)<5\left(-1\right)[/tex]

Simplify

[tex]n<-5[/tex]

Therefore, n = -5 is NOT a solution of the inequality because 'n' must be less than -5.

Hence,

NO (n = -5 is not a solution to the inequality).

Verification:

Given

[tex]6-n-6>11-6[/tex]

substitute n = -5

6 - (-5) - 6 > 5

6+5-6 > 5

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses

b. 2x - 7 and the opposite of 2x

Answers

Step-by-step explanation:

We need to write the sum of 2x - 7 and the opposite of 2x

Opposite of 2x is (-2x)

Sum means to add the number :

2x-7 + (-2x)

Remove parentheses,

2x-7 - 2x

Taking like terms together,

2x-2x-7= 0-7

= -7

Hence, the answer is -7.

Will is w years old.
Ben is 3 years older.
1. Write an expression, in terms of w, for Ben's age.
Jan is twice as old as Ben.
2. Write an expression, in terms of w, for Jan's age.
If you add together the ages of Will, Ben and Jan the total comes to 41 years.
3. Form an equation and solve it to work out how old Will, Ben, and Jan are.

Answers

Answer:

Will is 8 years old, Ben is 11 years old, and Jan is 22 years old

Step-by-step explanation:

Since Ben is 3 years older, his age can be represented by w + 3

Jan is twice as old as Ben, so her age can be represented by 2(w + 3)

Set up an equation that adds up these expressions and sets it equal to 41:

(w) + (w + 3) + 2(w + 3) = 41

Simplify, add like terms, and solve for w:

(w) + (w + 3) + 2(w + 3) = 41

(w) + (w + 3) + (2w + 6) = 41

4w + 9 = 41

4w = 32

w = 8

So, Will is 8 years old.

Find Ben's age by adding 3 to this:

8 + 3

= 11

Find Jan's age by multiplying this by 2:

11(2)

= 22

So, Will is 8 years old, Ben is 11 years old, and Jan is 22 years old
