Answer:
x = 45
Step-by-step explanation:
(2x + 6)/3 = (5x - 1)/7
<em>Cross multiply</em>
7(2x + 6) = 3(5x - 1)
<em>Expand both expressions</em>
14x + 42 = 15x - 3
<em>Collect like terms</em>
42 + 3 = 15x - 14x
45 = x
x= 45
<em>Check:</em>
7(2*45 + 6) = 3(5*45 - 1)
7(90 + 6) = 3(225 - 1)
7 * 96 = 3 * 224
672 = 672
Answer:
-69
Step-by-step explanation:
k(-5) = 10*-5 -19
= -50-19
=-69
Answer:

Step-by-step explanation:
Look at the picture.
The formula of a slope:

From the graph we have two points (0, -4) and (3, 0).
Substitute:

Answer:
reflex angle
Step-by-step explanation:
Acute is less than 90
Right = 90
Obtuse is greater than 90 and less than 180
Straight is 180
Reflex is greater than 180 and less than 360
This is greater than 90 and less than 180 so it is a reflex angle
