(5x)/7 - x/14 = 9/7 solve for the unknown value this is a linear equation

Ahat [919]

Step-by-step explanation:

$\longmapsto \rm \dfrac{5x}{7} - \dfrac{x}{14} = \dfrac{9}{7} \\$

$\longmapsto \rm \dfrac{10x + x}{14} = \dfrac{9}{7} \\$

$\longmapsto \rm \dfrac{11x}{14} = \dfrac{9}{7} \\$

→ 11x(7) = 14(9)

→ 77x = 126

→ x = 126 ÷ 77

→ x = 1.63

Quadratic function of Y=x2-2x-3

Svetach [21]

Ok! So, given a quadratic function, y = ax2 + bx + c, when "a" is positive, the parabola opens upward and the vertex is the minimum value. On the other hand, if "a" is negative, the graph opens downward and the vertex is the maximum value. Now, let's refer back to our original graph, y = x2, where "a" is 1.

Hope this helps.

Find the ordered pairs for x and y intercepts of the equation 3x - 2y =18

My name is Ann [436]

   3x - 2y = 18
Wherever the line crosses the
x-axis, y=0.    3x        = 18
   x = 6
The x-intercept is (6, 0) .

   3x - 2y = 18
Wherever the line crosses the
y-axis, x=0.    - 2y = 18
   y = -9
The y-intercept is    (0, -9) .

exterior angle of a triangle is equal to the sum of two opposite interior angle

4n-18+n+8=133-6n

5n+6n=133+10

11n=143

n=143/11

n=13

exterior angle =133-6*13=55°

option A.55°
