Please help first correct will get brianliest. Find the value of x that makes DEF XYZ

erica [24]

Answer:

x = 7

Step-by-step explanation:

The larger triangle is twice as big as the smaller triangle. Therefore, the length of the side EF is twice as large as the side YZ.

I multiplied 4.5 (the length of YZ) and 2 to get 9. The value of side EF is 3x-12 and should be equivalent to 9.

3x - 12 = 9

I solved this equation by adding 12 to both sides and dividing 3 on both sides.

The value of x is 7.

t = 19 weeks

Step-by-step explanation:

Linear Modeling

Some situations can be modeled as linear functions. If we are in a situation where a linear model is suitable, then we need two sample points to make the model and predict future behaviors.

The linear function can be expressed in the slope-intercept format:

y = mx + b

Another equation of the line can be used when two points are given.

The equation of a line passing through points (x1,y1) and (x2,y2) can be written as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The population of beetles is a situation where we must apply linear modeling. Two points are given. For time t=0, the population is P=13. The point is (0,13). For time t=8, P=75. The point is (8,75).

Find the equation of the line:

$\displaystyle P-P_1=\frac{P_2-P_1}{t_2-t_1}(t-t_1)$
