Put the following equation of a line into slope intercept form, simplifying all fractions. 8x+10y=-30
Mama L [17]

The slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.

<h3>What is the slope-intercept form of the given equation?</h3>

The slope-intercept form is expressed as;

y = mx + b

Where m is the slope and b is the y-intercept.

Given the equation in the question;

8x + 10y = -30

To convert to slope intercept form, we make y the subject of the formula and simplify.

8x + 10y = -30

10y = -8x - 30

Divide each term by 10

10y/10 = -8x/10 - 30/10

y = -4x/5 - 3

y = (-4/5)x - 3

Therefore, the slope-intercept form of the given equation ( 8x 10y=-30 ) is y = (-4/5)x - 3.

The coins in the store s cash register total $12.50. The cash register contains only nickels, dimes, and quarters. There are twi
Oduvanchick [21]
Nickels is 0,05 of dolar - n
dimes is 0,1 o dolar -d
quarters is 0,25 of dolar -q
dimes =2nickels
d=2n
quarters=2dimes
q=2d=4n
12,5=n(0,05)+2n(0,1)+4n(0,25)
12,5=0,05n+0,2n+n
12,5=1,25n
n=10
q=4n=40
There are 40 quarters

1.)The angle θ lies in Quadrant IV. sinθ=−2/3 What is cosθ?
AveGali [126]

Answer:

1. From sin²θ +cos²θ =1 and sinθ=-2/3, we see that cosθ=√(1-sin²θ) or cosθ=√5/3, where the sign of cosine is positive as it is in Quadrant IV. x lies in 4th quadrant , cos x is +ve. , cos x = √5/3. Answer.

answer : cos x = √5/3

2.  4/3

3.  sin (- theta)  = - sin (x)        so sin x = 1/6

 tan = sin / cos   =  1/6  /  cos  =  - sqrt35/35     solve for cos

                        cos =  1/6 * (-35/sqrt35)

                       

                                  = -35 sqrt35 /210

answer : −35/√210

4. The cosine function is an even function, so cos(θ) = cos(-θ).

The relationship between sin(θ) and cos(θ) is sin(θ) = ±√(1 -cos(θ)^2)

For sin(θ) < 0 and cos(θ) = (√3)/4,  sin(θ) = -√(1 -3/16) = -√(13/16)

sin(θ) = -(√13)/4   For sin(θ) < 0 and cos(0) = √(3/4), ...

sin(θ) = -√(1 -3/4) = -√(1/4)       sin(θ) = -1/2

answer : -13/√4

5.  answer : tan^2 θ ⋅ cos^2 θ = 1 − cos^2 θ would be the first step
