Write the equations for 74,2 and 49

serious [3.7K]

Answer:

$x+10y=94$

Step-by-step explanation:

Assuming we want to find the equation (74,2) and (4,9)

This is an equation of a straight.

Let this equation be y=mx+b.

$m=\frac{9-2}{4-74} =-\frac{1}{10}$

We substitute the slope and (4,9) to get:

$y-9=-\frac{1}{10}(x-4)$

We rewrite in standard form to get:

$x+10y=94$

Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, squ

vivado [14]

Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.

Solve the following system of equation

krok68 [10]

Answer:

x = 6 , y = -4 , Z = -1

Step-by-step explanation:

Solve the following system:

{2 x + 3 y - Z = 1 | (equation 1)

3 x + y + 2 Z = 12 | (equation 2)

-3 + x + 2 y = -5 | (equation 3)

Express the system in standard form:

{2 x + 3 y - Z = 1 | (equation 1)

3 x + y + 2 Z = 12 | (equation 2)

x + 2 y+0 Z = -2 | (equation 3)

Swap equation 1 with equation 2:
