5 0

Answer:

D. 6

Step-by-step explanation:

Suppose the triangles are similar:

The side lenghts would be proportional as follows

XZ/DF = XY/DE

12/8 = 9/x cross multiply expressions

12x = 72 divide both sides by 12

x = 6

Answer:

The required equation of the line is y = [x]+2

Step-by-step explanation:

From the graph shown, we can see that the line dotted points forms a straight line. We are to find the required equation of the line formed.

The formula for calculating the equation of a straight line is expressed as y = mx+b where

m is the slope b is the y-intercept

<u>Get the slope 'm'</u>

m=\frac{y_2-y_1}{x_2-x_1}

Using the coordinate points (2, 0) and (4, 2)

m=\frac{2-0}{4-2}\\m=\frac{2}{2}\\m=1

<u>Get the y-intercept 'b'</u>

Substitute m = 1 and (2, 0) into y = mx+b as shown;

2=1(0)+b\\2=0+b\\b=2

Get the required equation. Recall that y = mx+b, hence;

y = 1x + 2\\y=x+2

The expression can also be written as  y = [x]+2

Whats the fraction 18/24 reduced to its lowest items?
asambeis [7]
Hello!

\sf Answer:

The fraction 18/24, reduced to its lowest terms, is: \boxed{3/4}
_____________________________

Divide both the numerator and the denominator by the GCD of 18 and 24, which is 6:

18 ÷ 6 = 3

24 ÷ 6 = 4

It's simplest form would be 3/4. This cannot be reduced further.
