Answer:
Step-by-step explanation:
39). y = 
x + 3
40). m = 
y - 
= m( x - 
)
(- 7, 5)
( - 12, 4)
m = ( 4 - 5 ) / ( - 12 + 7) = 1/5
y - 5 = (1/5)(x + 7) ⇒ y = 
x + 6.4
Answer:
8
Step-by-step explanation:
let the number=x
8(x-2)=16(x-5)
divide by 8
x-2=2(x-5)
x-2=2x-10
2x-x=-2+10
x=8
Answer:
-29/20
Step-by-step explanation:
The cosecant function is the inverse of the sine function. Both sine and cosecant are odd functions, meaning csc(-x) = -csc(x) = -1/sin(x).
csc(-θ) = -1/sin(θ) = -1/(20/29) = -29/20
To find your answer you must substitute y for 0.8
4x + (8)(0.8) = 40
Now solve for x
====================================================================
SOLVING...
<span>4x + (8)(0.8) = 40
</span><span>4x + 6.4 </span>= <span>40
</span>
Subtract 6.4 from each side
<span><span><span>4x</span>+ 6.4 </span>− 6.4 </span>= <span>40 − <span>6.4
</span></span>4x = 33.6
Divide each side by 4
4x ÷ 4 = 33.6 ÷ 4
x = 8.4
Sum of all exterior angle should be 360.
when the measure of each exterior angle is 36 then it has 10 sides and it is a
<span>Decagon </span>
