Complete the Point-Slope equation of (-8,-8) (-7,9)

Mathematics

Answer:

y = 17x +128

Step-by-step explanation:

P1(-8,-8)

P2(-7,9)

Slope,

m = (y2-y1)/(x2-x1) = (9-(-8))/(-8-(-7)) = 17/(-1) = 17

The point-slope equation is

y-y1 = m(x+x1)

y-(-8) = 17(x-(-8))

y+8 = 17x + 136

y = 17x +128

Given the line segment , state the ratio of the segment partitions as. Be sure to reduce fractions

Effectus [21]

Answer/Step-by-step explanation:

Line segment AB consists of segment AC and segment CB.

AC = 7 cm

CB = 21 cm

The entire segment, AB = 21 + 7 = 28cm

The ratio of the segments partitions can be stated as follows:

Ratio of AC to CB = AC:CB = 7:21 = 1:3 = $\frac{1}{3}$

AC is ¼ of AB $(\frac{1}{1 + 3} = \frac{1}{4})$

CB is ¾ of AB $(\frac{3}{1 + 3} = \frac{3}{4})$

Find x and y…………….????????

emmasim [6.3K]

Answer:

$let \: \alpha \: be \: the \: 45 \\ \tan( \alpha ) = \frac{p}{b} \\ \tan(45) = \frac{x}{3 \sqrt{2} } \\ 1 = \frac{x}{3 \sqrt{2} } \\ x = 3 \sqrt{2} \\ by \: using \: pythagoras \: therom \\ {y}^{2} = {3 \sqrt{2} }^{2} + {3 \sqrt{2} }^{2} \\ {y}^{2} = 18 + 18 \\ y = \sqrt{36} \\ y = 6$

Area of the plane figure

Viefleur [7K]

Answer:

Area = 16.8 * 7 / 2 = 58.8 ft2

Step-by-step explanation:

Have

18.2^2 = 7^2 + a^2

-> a^2 = 18.2^2 - 7^2

-> a^2 = 282.24

-> a = 16.8

Area = 16.8 * 7 / 2 = 58.8 ft2
