It is equilateral triangle, so the 3 sides have the same length

5x - 22 = 4x - 10
5x - 4x = -10 + 22
x = 12

The value of x is 12

What is the multiplicative rate of change of the function shown on the graph? Express your answer in decimal form. Round to the
allsm [11]
In linear models there is a constant additve rate of change. For example, in the equation y = mx + b, m is the constanta additivie rate of change.


In exponential models there is a constant multiplicative rate of change.


The function of the graph seems of the exponential type, so we can expect a constant multiplicative exponential rate.


We can test that using several pair of points.


The multiplicative rate of change is calcualted in this way:

 [f(a) / f(b) ] / (a - b)

Use the points given in the graph: (2, 12.5) , (1, 5) , (0, 2) , (-1, 0.8)

[12.5 / 5] / (2 - 1) = 2.5


[5 / 2] / (1 - 0) = 2.5


[2 / 0.8] / (0 - (-1) ) = 2.5


Then, do doubt, the answer is 2.5

A pair of parallel lines is cut by a transversal, as shown below.
MA_775_DIABLO [31]

Answer:

x=45\degree

Step-by-step explanation:

In the diagram, the measure of the (x+30\degree) angle is equal to the 75\degree angle.

These two angles are alternate angles.

We therefore set up the following equation and solve for x.

x+30\degree =75\degree

\Rightarrow x =75\degree-30\degree

\Rightarrow x =45\degree

Determine whether each equation is a linear equation. Write yes or no. If yes, write the equation in standard form.
Svetllana [295]
This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
