Answer:
x=1
y=-4
Step-by-step explanation:
4x+y=0 -> y= -4x
2(-4x)+x=-7
-8x+ x=-7
-7x=-7
x=-7/-7=1
y=-4 . 1 = -4
Check the picture below.
in the picture below, the bottom part
notice, 69° + 21° = 90°, so 21° and 69° are really complementary angles, sharing the same quadrant, meaning for any two sides of lengths say, a,b one angle will have a tangent of say b/a, then the other will have a tangent of a/b.
namely the tangent of each angle, is simply the other's tangent upside-down.
Answer:
Equation of the line with m=3 and b = 8.25 is y=3 x+8.25
Step-by-step explanation:
m = 3 and b = 8.25
To get equation of line we use y=mx+b
Where m represents the slope = 3
b represents the y intercept = 8.25
Plug in the values in y=mx+b
y= 3x + 8.25
Equation of the line with m=3 and b = 8.25 is y=3 x+8.25
Answer: 16
Step-by-step explanation:
if we were to list all the factors of 64 and 144
64= 1,2,4,8,8,16,32,64
144= 1,2,3,4,6,8,9,12,12,16,18,24,36,48,72,144
therefore the GCF of 64 and 144 is 16
Answer: Ron
