Answer:

6 and 2 is the solution

9 and 7 is not the solution

Step-by-step explanation:

6 and 2 is the correct answer as 3*y must equal or smaller than 18, we got:

3y = 3*6 = 18 (Yes)

3y = 3*2 = 6 (yes)

3y = 3*9 = 27 (No)

3y = 3*7 = 21 (No)

Hope this helped :3

Answer: (-1, 2)

explanation:

3(2x-y=-4)
6x-3y=-12

9x+3y=-3
6x-3y=-12

15x=-15
x=-1

2(-1) - y = -4
-2-y=-4
-y=-2

Tim wants to determine the height, x, of a nearby tree. He stands 35 feet

kodGreya [7K]

Answer:

x ≈ 29.4 ft

Step-by-step explanation:

The model is a right triangle.

Using the tangent ratio

tan40° = $\frac{opposite}{adjacent}$ = $\frac{x}{35}$ ( multiply both sides by 35 )

35 × tan40° = x , then

x ≈ 29.4 ft ( to 1 dec. place )

Determain the equation, in slope intercept form, of the line of the line that has a slope of -6 and passes through the point P(-

Vinil7 [7]

Answer:

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

m = -6

(-3, 2) ⇒ x₀ = -3, y₀ = 2

The point-slope form of the equation:

y - 2 = -6(x + 3)

So:

y - 2 = -6x - 18 {add 2 to both sides}

y = -6x - 16 ← the slope-intercept form of the equation

Si mi hermano gana 589 pesos diarios si ha trabajado 15 días de este mes ¿cuánto dinero ha ganado?

weeeeeb [17]

Mi hermano ha ganado un dinero devengado de 8835 pesos en 15 días.

En esta pregunta debemos determinar el dinero devengado por un período de 15 días a partir de una tasa diaria constante. Esa cantidad es igual al producto de la tasa diaria constante, en pesos por día, y el número de días trabajados, en días:

$x = 589\,\frac{\$}{dia}\times 15\,dias$

$x = 8835\,\$$

Mi hermano ha ganado un dinero devengado de 8835 pesos en 15 días.
