Find the Slope intercept form using points (-5,-1) and (2,3)

MariettaO [177]

Answer:

y = 4/7x + 13/7

Step-by-step explanation:

m = 3+1/2+5 = 4/7

i used the coords (-5, -1)

y + 1 = 4/7 (x+5)

y + 1 = 4/7x + 20/7

y = 4/7x + 20/7 - 1

y = 4/7x + 13/7

Given csc(A) = 65/16 and that angle A is in Quadrant I, find the exact value of sec A in simplest radical form using a rational

charle [14.2K]

Answer:

$secA = \frac{65}{63}$

Step-by-step explanation:

$cosec A = \frac{65}{16}\\\\sin A = \frac{1}{cosecA} = \frac{16}{65}\\\\cos^2 A = 1 - sin^2 A$

$= 1 - (\frac{16}{65})^2\\\\=\frac{4225-256}{4225}\\\\=\frac{3969}{4225}\\$

$cos A = \sqrt{\frac{3696}{4225}} = \frac{63}{65}$

$secA = \frac{1}{cosA} = \frac{65}{63}$

5x + 3 = x + 11<br> Please help

taurus [48]

Answer:

Step-by-step explanation:

5x + 3 = x + 11

5x - x + 3 = x - x + 11

4x + 3 = 11

4x + 3 - 3 = 11 - 3

4x = 8

4x / 4 = 8/ 4

x = 2

Hope this helps ^-^
