Supplementary angles sum to 180 degree

Let one angle be x

Then the other angle is x+80

Summing the 2 angle gives

x+x+80=180

2x+80=180

2x=180-80

X=50

Thus the angles are 50 degree and 50+80= 130 degree

If (-6,-38) and (5,28) are two anchor points on the trend line, then find the equation of the line

Delicious77 [7]

Answer:

The equation of the line is y = 6x - 2 .

Step-by-step explanation:

Formula for the equation of line is.

$(y - y_{1}) = m (x - x_{1})$

Where m is the slope.

$m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$

As given

If (-6,-38) and (5,28) are two anchor points on the trend line.

Than

$m = \frac{28 - (-38)}{5 - (-6)}$

$m = \frac{28 + 38}{5 + 6}$

$m = \frac{66}{11}$

m = 6

Put the value in the equation of a line.

$(y - (-38)) = 6 (x - (-6))$

$(y + 38) = 6 (x + 6)$

$(y + 38) = 6x + 6\times 6$

$(y + 38) = 6x + 36$

y = 6x +36 - 38

y = 6x - 2

Therefore the equation of the line is y = 6x - 2 .

17. $2u +5.2 \leq 9.4 + u \\2u - u \leq 9.4 -5.2\\u \leq 4.2$

18. $3(f+2) > 2f + 4\\3f + 6 > 2f + 4 \\3f-2f > 4-6\\f > -2\\$ The answer is I.

19. $4 < 6b -2 \leq 28\\4+2 < 6b \leq 28+2\\6 < 6b \leq 30\\6/6 < b \leq 30/6\\1 < b \leq 5$

a train of length 100 m is moving at speed of 50km/ hr. a horse is running alongside the train at a speed of 56km/h. How long wi

scoray [572]

Distance = 100 m = 100/1000 = 0.1 km speed of train = 50 km/hr speed of horse = 56 km/hr resultant speed = (56 – 50) 6 km/hr time = distance/speed time = 0.1/6 = 1/60 hr = 1 min
