We will determine the length of the segment DF as follows:

*We have that the triangles are similar, and therefore the following is true:

\frac{2}{1.34}=\frac{4}{DF}

Now, we solve for DF:

\Rightarrow DF=\frac{1.34\cdot4}{2}\Rightarrow DF=2.68

From this, we have that the length of the segment DF equals 2.68 units.

Y = –x + 4
aliina [53]
Y = -x + 4.....so sub in -x + 4 in for y in the other equation

x + 2y = -8
x + 2(-x + 4) = -8
x - 2x + 8 = -8
x - 2x = -8 - 8
-x = -16
x = 16

y = -x + 4
y = -16 + 4
y = - 12

one solution (16,-12)

Solve the system of equations using the elimination method. 1.Solve {x + 3y = -15
shutvik [7]

An equation is formed of two equal expressions. The solution is (-9,-2).

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the equation x + 3y = -15 and -3x + 2y = 23,

Step 1- Multiply the equations to make the coefficients match in either the x- or y-variable.

x + 3y = -15

3x + 9y = -45

Step2- After you multiply, add or subtract the two equations.

3x + 9y -3x + 2y = -45 + 23

Step 3- Then solve for the variables that is left.

11y = -22

y = -2

Step4- Substitute the value of y in any one of equations to solve for x.

x + 3(-2) = -15

x - 6 = -15

x = -9

Hence, The solution is (-9,-2).
