BRUH HELP

Mathematics
1 answer:
TEA [102]3 years ago
4 0

Answer:

(E) 9

Step-by-step explanation:

I found what numbers worked in all three cases. I found that when a = 4  b = 5  c = 0, all of the equations were satisfied.

Equation 1   4 + 5 = 9

Equation 2  4 + 0 = 4

Equation 3  5 + 0 = 5

Also, a + b+ c or 4 + 5 + 0 = 9

If these answers are correct, please make me Brainliest!

PLEASE HELP!!! Does anyone know the answer to this?!? (Y^3z^4)^(-3/4)
Svetach [21]

Answer:

y^ ⁻⁹/⁴ * z^⁽⁻³⁾

Step-by-step explanation:

(Y^3 z^4)^(-3/4)   = (y^3)^(-3/4) * (z^4)^(-3/4)

         =  y^3* ⁽⁻³/⁴⁾   * z^4 *⁽⁻³/⁴⁾

           =y^ ⁻⁹/⁴ * z^⁽⁻³⁾

Which graph shows a set of ordered pairs that represent a function?<br><br>Need help​
Sveta_85 [38]

Answer:

The third graph, the top right graph

Step-by-step explanation:

A function when determined graphically is a graph that passes the straight line test, which means if there is any two points on the graph which you can plot a vertical straight line going through both of them it is not a function.  If 1 x value is equal to 2 y values, it is not a function.

You are given a vector in the xy plane that has a magnitude of 87. 0 units and a y component of -66. 0 units. Determine the dire
Natalka [10]

You are given a vector in the XY plane that has a magnitude of 87. 0 units and a y component of -66. 0 units. The direction of the vector V is;

<h3>How to know the direction of a vector?</h3>

We know that the formula for 2 vectors like this in the x and y directions is; A = xi^ + yj^

Where A is the magnitude of the resultant

x is the value of the x-component

y is the value of the y-component

We are given;

Magnitude of vector = 84 units

Y-component of the vector = -67 units

Thus,

A = \sqrt(x^2 + y^2)\\\\87 = \sqrt(x^2+ (-66)^2)\\\\87^2= x^2+ 4356\\\\7569 = x^2+ 4356\\\\x= \sqrt(7569 - 4356)\\\\x = 56.68 units

From A above, let us take the positive value of the x-component and as such our original vector will be;

A = 56.68i^ - 66j^

The direction of the vector V is;

\theta = tan^{-1} \dfrac{y}{x}  \\\\\theta =  tan^{-1} \dfrac{-66}{56.68}  \\\theta =-27.15°

Since it points entirely to the negative x-axis, then the angle is;

180 - (-27.15) = 207.15°
