Find y of this shape.

Mathematics
1 answer:
Phantasy [73]3 years ago
6 0

Answer:

y = 75

Step-by-step explanation:

The sum of the angles in a quadrilateral = 360°

∠DGF and 80° form a straight angle and are supplementary, hence

∠DGF = 180° - 80° = 100°

Subtract the sum of the 3 angles from 360 for the value of y

y = 360 - (65 + 120 + 100) = 360 - 285 = 75

Here’s a graph of a linear function. Write the equation that describes that function.
lord [1]

Answer:

y = 5x - 5

Step-by-step explanation:

It appears that the graph intersects the y-axis at (0, -5).  This point is the y-intercept of the line.

As we move from (0, -5) to the point (2, 5), x increases by 2 and y increases by 10.  Thus, the slope of the line through these two points is

m = rise / run = 10 / 2  = 5.

The slope-intercept form of the equation of a straight line, y = mx + b, becomes y = 5x - 5

Given the equation:
Alisiya [41]

Answer:

x = 1 and x = \frac{-4}{5}

Step-by-step explanation:

In this equation, a=5, b=-1, c=-4.

Plug these into the quadratic formula:

x = \frac{1+\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}   and x = \frac{1-\sqrt{-1^{2}-(-4)(5)(-4) } }{2(5)}

Now, simplify the equations:

x = \frac{1+\sqrt{81} }{10} = \frac{1+9}{10} = \frac{10}{10} = 1

and

x = \frac{1-\sqrt{81} }{10} = \frac{1-9}{10} = \frac{-8}{10} = \frac{-4}{5}
