Answer:

First notice that θ is in quadrant I, where the sine and tangent will also be positive.

Then draw the angle in quadrant I. Drop a perpendicular to the x axis.

Since cosθ= 7/25, label the horizontal leg 7, and the hypotenuse 25; the vertical leg will be 24 by Pythagorean theorem.

Then sinθ=vertical/hypotenuse= 24/25 and tanθ= vertical/horizontal= 24/7

Write the equation of the line with a slope of 3/7 passing through the point (9,-2) in standard or slope-point form? ...?

Musya8 [376]

$y-y_1=m(x-x_1)
\\
\\ m= \frac{3}{7} 
\\
\\(9,-2) \Rightarrow x_1=9,y_1=-2
\\
\\ y-(-2)=\frac{3}{7} (x-9)
\\
\\y+2=\frac{3}{7}x-\frac{27}{7}
\\
\\y=\frac{3}{7}x-\frac{27}{7}-2
\\
\\y=\frac{3}{7}x-\frac{41}{7}$

Solve 2(y – 3) = 1.2 – y.

Anna007 [38]

Answer:

y = 2.4

Step-by-step explanation:

first distribute into the parenthesis' -

2(y-3) = 1.2 -y

2y - 6 = 1.2 - y

+y +y

3y -6 = 1.2

+6 +6

3y = 7.2

/3 /3

y = 2.4

hope this helps!!
