1) First, solve one linear equation for y in terms of x .

2) Then substitute that expression for y in the other linear equation.

3)Solve this, and you have the x -coordinate of the intersection.

4)Then plug in x to either equation to find the corresponding y -coordinate.

The relationship between numbers in list X and list Y follows the rule Y = X +2.05 what diagram shows this relationship
dexar [7]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=x+2.05

This is a linear equation ( equation of a line)

To graph the line find the intercepts

<u>The y-intercept</u> is the value of y when the value of x is equal to zero

For x=0

y=0+2.05=2.5

The y-intercept is the point (0,2.05)

<u>The x-intercept</u> is the value of x when the value of y is equal to zero

For y=0

0=x+2.05

x=-2.05

The x-intercept is the point (-2.05,0)

To graph the line plot the intercepts and then join the points

using  graphing tool

see the attached figure

Determine m∠U if m∠R = 9x - 10 and m∠U = 3x + 4.
german

Answer:

50.5 degrees

Step-by-step explanation:

Since this is a parallelogram then...

Angle U + Angle R = 180

3x+4+9x-10=180

Combine like terms

12x-6=180

Add 6 to both sides

12x=186

Divide both sides by 12

x=15.5

Now we plug 15.5 in for x to find Angle U

3(15.5)4=46.5+4=50.5

Angle U = 50.5 degrees

What is the primary difference between exponential and linear functions?
Yanka [14]

Answer:

A

Step-by-step explanation:

We know that the growth of a linear function will always be constant. So, that eliminates B and C.

A quadratic function can be a function such as x^2, or 5x^2+7x, etc.

An exponential function wouldn't be x^2, it would be 2^x! Or 3^x, or (1.738283)^x, etc. Therefore, D is eliminated.

So, the answer is \boxed{A} and we're done!
