Answer:
CD = AC
Step-by-step explanation:
CD = AC. "bisect" means "to divide in half." Half of AD is either AC or BC, which are equal to each other.
Answer:
X=4, y=-7
Step-by-step explanation:
To use elimination method, you want to cancel x or y when adding the equations together. So let’s multiply the first equation by -2
2(y)=2(-x-3)
2y=-2x-6
——————
add above equation 2y=-2x-6
to second equation Y=2x-15
add together. 3y=-21
Y=-7
—————————————-
solve for x by substituting y value (7) into either equation
y=-x-3
-7=-x-3
-4=-x
4=x
Answer:
I'm not sure if I'm correct but I'm pretty 75% sure it's option 2
Distance1 ÷ (Jaime's velocity + wind velocity) =
Distance2 ÷ (<span>Jaime's velocity - wind velocity)</span>
57 / (Jaime's velocity + 4) = 33 / (<span>Jaime's velocity -4)
</span>
57 / 33 = (Jaime's velocity + 4) / (Jaime's velocity - 4)
(57 * -4) +57 * (Jaime's velocity) = (33 * 4) +33 * (Jaime's velocity)
-228 + 57 JV = 132 + 33 JV
24 JV = 360
Jaime's velocity = 15

Square roots are most often written using a radical sign, like this, . But there is another way to represent the taking of a root. You can use rational exponents instead of a radical. A rational exponent is an exponent that is a fraction. For example, can be written as .
Can’t imagine raising a number to a rational exponent? They may be hard to get used to, but rational exponents can actually help simplify some problems. Let’s explore the relationship between rational (fractional) exponents and radicals.
