Answer:
Step-by-step explanation:
Lets add +5 in both the sides.
Now lets divide 12 on both the sides.
Answer:
Y=10x
(multiply 10 times the salamanders)
Step-by-step explanation:
a formula that can be used for this circumstance is a linear y=mx+b problem. for 1 salamander there are 10 frogs. so with this we can state that y=10x. whatever you plug into the x for the number of salamanders will give you the answer of how many frogs are in the pond. for example.
Y=10x
Y=10(3)
Y=30
30 frogs.
also because 10 is a nice number you can just multiply the number of salamanders times 10. 3*10=30
I factor it because you can't simplify
2x-8=2(x-4)
X^2+5x+4=(x+1)(x+4)
X^2-16=(x-4)(x+4)
X^2+8x+16=(x+4)(x+4)
Answer:
Usually the angles are measured from quadrant 1, where is the angle 0°.
If the angle moves counterclokwise, it is positive, if the angles goes clokwise, it is negative.
Then "On a coordinate plane, a ray moves counter-clockwise to form an angle. It moves from quadrant 1 to quadrant 4."
Will give a positive angle, and because we know that is in quadrant 4, the angle can be any angle between 270° and 360°
"On a coordinate plane, a ray moves counter-clockwise to form an angle. It moves from quadrant 1 to quadrant 2."
Same as before, this will create an angle with a positive measure, and the angle will be between 90° and 180°
