3:5:7:15
?:?:?:180
by using cross multiplication 3×180÷15=36
the measure of the smallest angle is 36°
I hope this helps you
x'=0 y'= -4
slope (x'-x)=y'-y
-3. (0-x)= -4-y
-3.-x= -4-y
3x= -4-y
y= -3x-4
I believe the answer is none of the above
Answer:
z ≤ 25
Step-by-step explanation:
multiply each side by 3 to get:
8 - z ≥ 33
-z ≥ 25
z ≤ -25
(you have to switch the inequality symbol when dividing or multiply by a negative)
Answer:
r = 3 + sin(θ)
Step-by-step explanation:
The curve extends below the x-axis, so the added constant must be larger than the coefficient of the sine function. There are two choices matching that description.
The extent in the -y (θ=-π/2) direction looks to be about 2/3 of the extent in the +x (θ=0) direction, so we expect the appropriate equation is ...
r = 3 + sin(θ)
