Pleaseeee help me with these 2 questions! I’m very confused and need help

Answer 1

Answer:

Q22.

9x - 2/3 y = -4

-2/3 y = -9x - 4

y = (-3/2) (-9x - 4) = (27/2)x + 6

That's a slope of 27/2 which means for every increase of 1 in x, y increases by 27/2.

Q23.

g(x) = (3/4) x + 5

Is that steeper than y=x? The function g has a slope of 3/4 and y=x has a slope of 1, which is more.

Answer: FALSE, g is less steep than y=x

Taking the slope about different points, we have
$m_(1) = ( y_(2)- y_(1) )/(x_(2)- x_(1)) = (100-63)/(18-12) = (37)/(6) =6 (1)/(6) \n m_(2) = ( y_(2)- y_(1) )/(x_(2)- x_(1)) = (30-88)/(8-16) = (-58)/(-8) =7 (1)/(4)$
The slopes are positive but are not equal, which means that that the association is positive non linear association.

What is the rate of change of the function?

Answers

Answer:

Option A

Step-by-step explanation:

The given function is a linear function therefore rate of change of this function will be the slope of the given line.

Since this line passes through two points ( 0,1 ) and ( 0.5 0 )

the slope of the line = $((y-y'))/((x-x'))$

slope = $((1-0))/((0-0.5))$

= ( -2 )

Therfore, Option A will be the answer.

The rate of change of function is,

m = - 2

We have to given that,

A function is shown in figure.

Since, The rate of change of linear function is slope of line.

Here, Two points on the line are (1, - 1) and (0, 1)

Since, The equation of line passes through the points (1, - 1) and (0, 1)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-1)) / (0 - 1)

m = 2 / - 1

m = - 2

So, The rate of change of function is,

m = - 2

I need answers for 32 to 26

Answers

The numbers are 48, 56, 29, __, 42 and 27
The median is 37 and the range is 29.
First arrange the numbers in order from smallest to largest.

27, 29, 42, 48, 56
The median is 37 so the unknown number must fall between 29 and 42.

27, 29, ___ , 42, 48, 56
Because there are 6 numbers there is no middle number. The median will be the average of the 3rd and 4th number.
Let the unknown number be X
(X + 42) divided by 2 = 37
X + 42 = 74
X = 32

The range is from 27 to 56 which is 29
