Answer:

(5,4) is the solution

Step-by-step explanation:

2x + y = 14 --> y = -2x + 14

Substitute y = -2x + 14 into 3x - 2y = 7


3x - 2( -2x + 14) = 7

3x + 4x - 28 = 7

7x = 35

x = 5

y = -2(5) + 14

y = -10 + 14

y = 4

Answer:

C) (5,4)

Step-by-step explanation:

So 4x+2y=28. So now we can write 7x=35. X=5. So now we can plug it in! So y=4.

You are interested in the relationship between leisure activities and mood. One group of participants watches at least 2 hours o
Romashka [77]

Answer:

The most appropriate statistical test to use to compare the mood scores from the different groups is independent sample t-test.

Step-by-step explanation:

The Independent Samples t-test examines the means of two independent groups to see if statistical evidence exists to show that the related population means differ significantly.

The Independent Samples t-test is also known as Independent t-test, Independent Two-sample t-test, and among others.

It should be note that only two (and only two) groups can be compared using the Independent Samples t-test. It is not possible to use it to make comparisons between more than two groups.

Therefore, the most appropriate statistical test to use to compare the mood scores from the different groups is independent sample t-test.

Solve x2 – 5x – 24 = 0 by completing the square
boyakko [2]

The solutions of the equation x² – 5x – 24 = 0 will be 8 and -3. Then the correct option is D.

<h3>What is a factorization?</h3>

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The quadratic equation is given below.

x² – 5x – 24 = 0

Then the factor of the equation will be

       x² – 5x – 24 = 0

x² – 8x + 3x – 24 = 0

x(x – 8) + 3(x – 8) = 0

       (x – 8)(x + 3) = 0

                          x = 8, -3

Then the correct option is D.

More about the factorization link is given below.

G(x) f(x) = −6x − 3 cosine function with y intercept at 0, negative 3 h(x) = 2 cos(x + π) − 1 Using complete sentences, explain
kicyunya [14]

A function assigns the values. The function that has the greatest y-intercept is h(x).

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

There are three function, g(x){given in the graph below}, f(x)= -6x-3, and -3h(x) = 2 cos(x + π) − 1, the y-intercept of the function is the point at which the graph intersects the y-axis. Therefore, the y-intercept are,

g(x) = -3

f(x) = -3

h(x) = 1

Hence, the function that has the greatest y-intercept is h(x).
