Triangle DEF has vertices D(0,0), E(7,0), and F(3,7).
Leni [432]

Answer:

(3, 1.7)

Step-by-step explanation:

The point at which the vertices of a triangle meet is known as the orthocenter of the triangle. The orthocenter passes through the vertex of the triangle and is perpendicular to the opposite sides.

Two lines are perpendicular if the product of their slopes is -1.

The slope of the line joining D(0,0), F(3,7) is:

m_1=\frac{7-0}{3-0}=\frac{7}{3}

The slope of the line perpendicular to the line joining D and F is -3/7. The orthocenter is perpendicular to the line joining D and F and passes through vertex E(7, 0). The equation is hence:

y-y_1=m(x-x_1)\\\\y-0=-\frac{3}{7} (x-7)\\\\y=-\frac{3}{7}x+3 \ .\ .\ .\ (1)

The slope of the line joining E(7,0), and F(3,7). is:

m_1=\frac{7-0}{3-7}=-\frac{7}{4}

The slope of the line perpendicular to the line joining E and F is 4/7. The orthocenter is perpendicular to the line joining E and F and passes through vertex D(0, 0). The equation is hence:

y-y_1=m(x-x_1)\\\\y-0=\frac{4}{7} (x-0)\\\\y=\frac{4}{7} x\ .\ .\ .\ (2)

The point of intersection of equation 1 and equation 2 is the orthocenter. Solving equation 1 and 2 simultaneously gives:

x = 3, y = 1.7

Determine which of the following statements is NOT correct. 00:00 The equation x + 1.793 = 2.42 can be rewritten as x-1.793 = 2.
Mademuasel [1]

• x+1.793= 2.42

x-1.793= 2.42-1.793 FALSE

• 5.25x = 15.75

Solve for x, by dividing both sides of the equation by 5.25

x = 15.75/5.25

x = 3 TRUE

• The equation x = 2.4 *11.62 can be rewritten as x = 11.62 * 2.4. TRUE

• The solution to the equation x + 9.43 = 16.09 is x = 6.66.​

x+9.43 = 16.09

Subtract 9.43 from both sides of the euqation:

x-9.43+9.43= 16.09-9.43

x = 6.66 TRUE
