Equation describes a sloping line. For any
equation ax+by+c = 0, slope is .<span>X intercept is found by setting y to 0: ax+by=c becomes ax=c. that means that x = c/a. 30/5 = 6.Y intercept is found by setting x to 0: the equation becomes by=c, and therefore y = c/b. Y intercept is 30/-3 = -10.Slope is -5/-3 = 1.66666666666667.<span> Equation in slope-intercept form: y=1.66666666666667*x+-10.</span></span>

Can anyone help with these ? I'll give brainlyiest to anyone that can help with all of them! :) Thank you in advance .

Answer:

1. (a) A function is a mapping f:x\rightarrow y where there should be different values of y for different x.

So, given ordered pairs:

(3,7), (3,8) ,(3,-2) ,(3,4) ,(3,1)

It is not a function because there are multiple y values for single x-value.

Option 2 is correct.

(b) We need to find range of the function f(x)= -4x +1

So, we have given the domain which means the value of x we will put thses given values of x to find y

Values of y is the range in a function

So, given domain is: {-5,-1,0,2,10}

When x= -5

y=-4(-5)+1=21

When x=-1

y=-4(-1)+1=5

when x=0

y=-4(0)+1=1

when x=2

y=-4(2)+1=-7

when x=10

y=-4(10)+1=39

So, Range is: {-39,-7,1,5,21}

Option 1 is correct.

(c) We have given a function v(c)=98c

Where c is the number of cup jug of milk which is 16.

Put c=16 in given function

v(c)=98\cdot 16

v(c)=1568

So, c=16, v(c)=1568 is reasonable domain and range of the function.

Option 1 is correct.

(d) We need to find the inverse of given ordered pairs (1,2) (3,4) ,(6,8)

So, the inverse means values of x and y interchange.

So, the required inverse is: (2,1) ,(4,3) ,(8,6)

Option 3rd is correct.

2. We need to find the inverse of given scatter plot in which we have to find the inverse

So, given scatter plot represents (-4,-2) ,(1,-1) ,(2,1) ,(3,2)

So, in inverse values of x and y interchange

So, inverse scatter plot should represent (-2,-4) ,(-1,1) ,(1,2), (2,3)

Attached is the scatter plot inverse

Graph 1 is correct.

3.We have been given a function:

f(x)=3x

So, f(x)=y

That is y=3x

We will find x from above equation we get

x=\frac{y}{3}

Now, interchange x and y

y=\frac{x}{3}

\Rightarrow f(x)=\frac{x}{3} is the required inverse

Therefore, option 3rd is correct.
