What is the point (-9,-3) after rotating 180 counterclockwise

sleet_krkn [62]

Answer:

(9, 3)

Step-by-step explanation:

When a point is rotated 180 degrees, you take the opposite of the coordinates.

i.e (5, 6) ---> (-5, -6)

Solve for F ------- 2/3 + f = 1/5 A= 13/15 B= 7/15 C= - !3/15 D= - 7/15

nikdorinn [45]

$\\ \sf\longmapsto \dfrac{2}{3}+f=\dfrac{1}{5}$

$\\ \sf\longmapsto f=\dfrac{1}{5}-\dfrac{2}{3}$

$\\ \sf\longmapsto f=\dfrac{3-10}{15}$

$\\ \sf\longmapsto f=\dfrac{-7}{15}$

Can someone help?

lutik1710 [3]

Answer:

21(a) 8 cm

21(b) 1.6 cm/sec

Step-by-step explanation:

21(a)

21 cm = 13 cm = 8 cm

21(b)

Increase in depth from 6 sec to 11 sec: 8 cm

Time from 6 sec to 11 sec: 11 sec - 6 sec = 5 sec

Rate = (8 cm)/(5 sec) = 1.6 cm/sec

what is the equation, in slope- intercept form, of the line that contains the points (-3,4) and (5,7)

gavmur [86]

Answer:

y = $\frac{3}{8}$ x + $\frac{41}{8}$

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

To calculate the slope use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (5, 7)

m = $\frac{7-4}{5+3}$ = $\frac{3}{8}$ , hence

y = $\frac{3}{8}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

using (5, 7 ), then

7 = $\frac{15}{8}$ + c ⇒ c = 7 - $\frac{15}{8}$ = $\frac{41}{8}$

y = $\frac{3}{8}$ x + $\frac{41}{8}$ ← equation in slope-intercept form
