Csc(x) tan(x) =1/cos(x) says to move everything to the right but i don’t know how

lara31 [8.8K]

Answer:

see below

Step-by-step explanation:

csc(x)tan(x)=

rewrite in terms of sin and cos (csc = 1/sin; tan = sin/cos)

(1/sin(x)) (sin(x)/cos(x))=

the sin(x) cancel out and you are left with 1/cos(x)

Can someone help me with this ????

Answer:

A.

$(\frac{3}{3+5})(2 - (-14))+ (-14)$

Step-by-step explanation:

Given

Ratio = 3:5

Q = -14

S = 2

Required

Which solution uses $(\frac{m}{m+n})(x_2 - x_1)+ x_1$

From the given parameters;

$m:n = 2:5$

$m = 2\ and\ n = 5$

$x_1 = -14\ and\ x_2 = 2$

Substitute the above values in $(\frac{m}{m+n})(x_2 - x_1)+ x_1$

This gives:

$(\frac{m}{m+n})(x_2 - x_1)+ x_1$

$(\frac{3}{3+5})(2 - (-14))+ (-14)$

From the list of given options, only option A uses the given form of the formula...

Find the x - and y -intercepts of the graph of the linear equation -4x+8y=-16 .

Sav [38]

Answer:

x: (4, 0)
y: (0, -2)

Step-by-step explanation:

To find the x-intercept, set y=0 and solve for x. That will mean dividing by the coefficient of x:

-4x +0 = -16

x = -16/-4 = 4 . . . . the x-intercept

__

To find the y-intercept, set x=0 and solve for y. That will mean dividing by the coefficient of y:

0 +8y = -16

y = -16/8 = -2 . . . . the y-intercept

__

The x- and y-intercepts are (4, 0) and (0, -2), respectively.

_____

Additional comment

The standard form equation of a line, ax+by=c, is especially nice for finding the intercepts, as they are always (c/a, 0) and (0, c/b). Once you see this, you can do a question like this in your head.
