Suppose point z is halfway between point w and x a standard numberline, and point x is halfway between points z and y. Where is
Delicious77 [7]

Answer:

The point w is located at -4/3

Step-by-step explanation:

Point z is halfway between point w and x

Point x is halfway between point z and y

Point z is located at 1/3 and point y is located at 11/3

Please refer to the number line attached

Then the x is located at the mid-point of z and y

x = \frac{z+y}{2} \\\\x = \frac{\frac{1}{3}+ \frac{11}{3} }{2}

x = 2

Since z is the mid-point of w and x

z = \frac{w+ x }{2}\\\\\frac{1}{3}  = \frac{w+ 2 }{2}\\\\\frac{2}{3}  = w+ 2 \\\\w = \frac{2}{3} - 2\\\\w = -\frac{4}{3}

Therefore, the point w is located at -4/3

Simplify the expression using the distributive property. –4(–3x + 11) 1. Distribute the –4 through the parentheses: -4(–3x) + (-
diamong [38]
Let’s start with -4(-3x + 11) so, -4•-3x is 12x,because multiplying 2 negatives creates a positive. As for -4•11, it is -44. So, it should be 12x + -44. I hope this helps!

Which equation is correct
Sergeeva-Olga [200]
1. Two of the main identities used in trigonometry for right triangles (Triangles that have an angle of 90°) are: Sine (Sin) and Cosine (Cos).


 Sin x°=Opposite/Hypotenuse

 Cos x°=Adjacent/Hypotenuse

 2. The inverse of Sinx° is Cosec x°, then:

 Cosec x°=1/Sin x°

 3. The inverse of Cos x° is Sec x°, then:

 Sec x°=1/Cos x°

 4. Keeping this on mind, you have:

 Cosc x°=Hypotenuse/Opposite

 Sec x°=Hypotenuse/Adjacent

 5. Therefore, the correct answer is:

 The third option: Cosec x°=Hypotenuse/Opposite.
