Answer:
<em>I</em><em> </em><em>answered </em><em>y</em><em>our</em><em> </em><em>question </em><em>.</em><em> </em><em>Hope</em><em> </em><em>this</em><em> </em><em>helps</em><em>.</em>
you have to write a point slope equation which is formula: y-y1= slope(x-x1)
substitution this equation into your problem
y-7= -4(x-(-2)) ----------> y-7 = -4(x+2)
simplifying this equation
the equation is y=-4x -1
then you stated that (a,-2) then substitution this
-2 = -4x -1
-3 = -4x
x= 3/4
therefore a= 3/4
3 and a number that = 28 Let the number be n
3 + n = 28
n = 28 - 3
n = 25
The quotient of 25 and the sum 3 and a number
Sum = 25 + 3 = 28
Quotient = 25 / 28
Answer:
the most accurate answer would be option 3 relatively speaking
Step-by-step explanation:
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = 
= 
= 
( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = 
≈ 19.4 cm ( to 3 significant figures )
