### Terri is analyzing a circle, y2 + x2 = 36, and a linear function g(x). Will they intersect? y2 + x2 = 36 g(x) graph of the function y squared plus x squared equals 36 x g(x) −4 −4 −2 −2 2 2 Yes, at positive x-coordinates or zero Yes, at negative x-coordinates or zero Yes, at negative and positive x-coordinates or zero No, they will not intersect

The graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

Step-by-step explanation:

The equation of circle is given as:

also the graph of the function g(x) is given by:

We are given a set of values in a table as:

x         g(x)

−4       −4

−2        −2

2          2

Hence, the function g(x) could be computed with the help of slope intercept form of a equation as:

y=mx+c; where m denotes the slope of the line and c denotes the y intercept.

when x=-4 g(x)=y=-4

-4=-4m+c

also when x=-2 then y=g(x)=-2

-2=-2m+c

on solving the above two equations using elimination method we get,

m=1 and c=0

hence, y=g(x)=x

Now we are asked tgo find whether the graph of the circle and g(x) intersect each other or not.

Clearly from the graph we could see that the graph of the circle and function g(x) intersects at the positive and negative x-coordinates as well as at the origin.

That would be C.

20x + 5y = 50
5y = - 20x + 50
y = -20/5x + 50/5
y = - 4x + 10

If a is a rational number and b is a rational number, why could c be an irrational number? represents the solution set of the compound inequality mc011-1.jpg?

Because even though 'a' and 'b' are rational, and their squares are

has a rational square root.

√5 is irrational

'c' is rational only when 'a', 'b', and 'c' form a . . . . . wait for it . . . . .

### How many solutions exist for the given equation? 12x + 1 = 3(4x + 1) – 2

There are infinite number of solution

Step-by-step explanation:

We have to tell the number of solution of given equation

12x+1=3(4x+1)-2

We solve the expression on the right hand side

i.e.   3(4x+1)-2

=  12x+3-2

= 12x+1

Which is equal to the expression on the left hand side.

Hence, for any value of x right hand side equals left hand side

Hence, there are infinite number of solution

Range defined as the complete set of possible values of the dependent variable,

The range is defined as the resulting y-values we get after substituting all the possible values of x from domain.

Given the function:

Also, x ∈Domain = {-1, 0, 1, 2, 3}

For x = -1;

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

For x = 0;

y = 4(0)-1 = 0 -1 = -1

For x = 1;

y = 4(1)-1 = 4-1 =3

For x = 2;

y = 4(2)-1 = 8-1 =7

For x = 3;

y = 4(3)-1 = 12-1 =11

Therefore, the range of the function are the set of all values of y i,e

Range = {-5, -1, 3, 7 , 11}

You skiped one operator.

I assume that the function is f(n+1) = f(n) - 2.

f(1) = 10
f(2) = f(1) - 2 = 10 - 2 = 8
f(3) = f(2) - 2 = 8 - 2 = 6
f(4) = f(3) - 2 = 6 - 2 = 4
f(5) = f(4) - 2 = 4 -2 = 2

We have two unknowns from the equation therefore, two equations are needed. These equations are:

3x + y = 9
y = –4x +10

To solve for y, we first substitute the second equation to the first one.
3x + –4x +10= 9
x = 1

We substitute the value of x to either of the equations and solve for y.

y = –4(1) +10
