Answer:

Step-by-step explanation:
We have been given a graph of similar triangles. We are asked to find the value of x.
Since we know that corresponding sides of similar triangles are always in same proportion, so we will use proportions to find the length of x.

Upon cross multiplying our equation we will get,
Upon distributing 4 we will get,

Let us subtract 12 from both sides of our equation.

Upon dividing both sides of our equation by 4 we will get,
Therefore, the value of x will be 12.

Step-by-step explanation:
we know that
A mixed number is the sum of a integer and a fractional part
we have

so


substitute

Group terms



The graphed line is y = 3/2x + 3.
In order to solve for this, we need to start by finding the slope. To find the slope, we start by selecting two points on the graph. We'll use (0, 3) and (-2, 0).
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - 0)/(0 - -2)
m = 3/2
Now that we have this, we can use a point and slope intercept form to find the intercept.
y = mx + b
0 = (3/2)(-2) + b
0 = -3 + b
3 = b
And we can use the slope and intercept to model the equation as y = 3/2x + 3
