I'm guessing you mean which equation Equals -9
In each equation you are needing to get rid of X so you divide on both sides
A) -45=5x
-45/5=x
-9=x
and I double checked to make sure nothing else equaled -9 so Your answer Is A
Hope this helped!
The equation can be written in vertex form as
y = a(x +2)² - 3
Substituting the given values, we can find the coefficient "a".
-5 = a(-1+2)² -3
-2 = a . . . . . . . . . add 3 and simplify
The coefficient of the squared term is -2.
One correct answer:
D
Because all of the sides are even, and it has no 90 degree angles.
Answer:
5√2 units ≈ 7.07 units
Step-by-step explanation:
The ratio of leg to hypotenuse in an isosceles right triangle is ...
leg/hypotenuse = 1/√2
Multiplying by the length of the hypotenuse, we have ...
leg = hypotenuse/√2 = 10/√2
leg = 5√2 . . . . rationalize the denominator
The length of one leg is 5√2 units, about 7.07107 units.
