Hi!
Explanation: <em><u>First you had to convert element to fraction is 2=2/1 ,and it gaves us -4/5÷2/1. Then apply to the fraction rules, -4/5 *1/2=-2/5 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie </u></em>
y = - 7x - 20
the equation of a line in ' slope- intercept form ' is
y = mx + c → (m is the slope and c the y- intercept)
here m = - 7 ⇒ y = - 7x + c
to find c substitute ( - 4 , 8 ) into the equation
8 = 28 + c ⇒ c = 8 - 28 = - 20
y = - 7x - 20 → equation in slope- intercept form
I think you need to post a graphic.
Answer:
a. 42, 48
Step-by-step explanation:
The angles being complementary means their total measure is 90°.
(12q -9) +(8q +14) = 90
20q +5 = 90 . . . . . . . . . . . simplify
20q = 85 . . . . . . . . . . . . . . subtract 5
q = 4.25 . . . . . . . . . . . . . . . divide by 20
Now, put this value into the expressions for the angle measures:
12q -9 = 12·4.25 -9 = 42
8q +14 = 8·4.25 +14 = 48
These two angle measures total 90, so our answer checks OK.
The measures of the angles are 42 and 48 degrees.
