Raise 8 to the 5th power, then subtract the result from h. What would the expression be?

lawyer [7]

The equation would look like this:

h - 8⁵

To solve for the value of h.
It must be in standard form, where one side is equal to 0.

h - 8⁵ = 0
h = 8⁵
h = 8 x 8 x 8 x 8 x 8
h = 32,768

The exponent above the number indicates the number of time its base will be multiplied by itself. In this case, the base will be multiplied 5 times.

To check: h = 32,768
h - 8⁵ = 0
32,768 - 32,768 = 0
0=0

If Morgan and Kira have a number of jelly beans in a ratio of 5 : 3. Kira and Mann have a

castortr0y [4]

Answer:

Step-by-step explanation:

Kira has 3/8 of the total of Jelly Beans available. Morgan has the other 5/8

So if there are 56 Jelly beans in total 3/8 * 56 = 21 which would be Kira's share.

Morgan would have 5/8 * 58 = 35 Jelly beans (Not that this is really relevant).

Now Kira and Mann have a ratio of 6:1 which means that she has 6/7 of the total between those two. He therefore must have 1/7 of the total.

Her total is 21.

1/7 of 21 = 3

Therefore Mann would have 3 jelly beans.

3/8 * 1/7 is the total the number of Jelly Beans that he would have if the total was N

N(3/8 * 1/7) = N (3/56)

without building the graph, find the coordinates of the point of intersection of the lines given by the equation y=3x-1 and 3x+y

DaniilM [7]

<h2><u>1. Determining the value of x and y:</u></h2>

Given equation(s):

$y = 3x - 1$
$3x + y = -7$

To determine the point of intersection given by the two equations, it is required to know the x-value and the y-value of both equations. We can solve for the x and y variables through two methods.

<h3 /><h3><u>Method-1: Substitution method</u></h3>

Given value of the y-variable: 3x - 1

Substitute the given value of the y-variable into the second equation to determine the value of the x-variable.

$\implies 3x + y = -7$

$\implies3x + (3x - 1) = -7$

$\implies3x + 3x - 1 = -7$

Combine like terms as needed;

$\implies 3x + 3x - 1 = -7$

$\implies 6x - 1 = -7$

Add 1 to both sides of the equation;

$\implies 6x - 1 + 1 = -7 + 1$

$\implies 6x = -6$

Divide 6 to both sides of the equation;

$\implies \dfrac{6x}{6} = \dfrac{-6}{6}$

$\implies x = -1$

Now, substitute the value of the x-variable into the expression that is equivalent to the y-variable.

$\implies y = 3(-1) - 1$

$\implies$ $\ \ = -3 - 1$

$\implies$ $= -4$

Therefore, the value(s) of the x-variable and the y-variable are;

$\boxed{x = -1}$ $\boxed{y = -4}$

<h3 /><h3><u>Method 2: System of equations</u></h3>

Convert the equations into slope intercept form;

$\implies\left \{ {{y = 3x - 1} \atop {3x + y = -7}} \right.$

$\implies \left \{ {{y = 3x - 1} \atop {y = -3x - 7}} \right.$

Clearly, we can see that "y" is isolated in both equations. Therefore, we can subtract the second equation from the first equation.

$\implies \left \{ {{y = 3x - 1 } \atop {- (y = -3x - 7)}} \right.$

$\implies \left \{ {{y = 3x - 1} \atop {-y = 3x + 7}} \right.$

Now, we can cancel the "y-variable" as y - y is 0 and combine the equations into one equation by adding 3x to 3x and 7 to -1.

$\implies\left \{ {{y = 3x - 1} \atop {-y = 3x + 7}} \right.$

$\implies 0 = (6x) + (6)$

$\implies0 = 6x + 6$

This problem is now an algebraic problem. Isolate "x" to determine its value.

$\implies 0 - 6 = 6x + 6 - 6$

$\implies -6 = 6x$

$\implies -1 = x$

Like done in method 1, substitute the value of x into the first equation to determine the value of y.

$\implies y = 3(-1) - 1$

$\implies y = -3 - 1$

$\implies y = -4$

Therefore, the value(s) of the x-variable and the y-variable are;

$\boxed{x = -1}$ $\boxed{y = -4}$

<h2><u>2. Determining the intersection point;</u></h2>

The point on a coordinate plane is expressed as (x, y). Simply substitute the values of x and y to determine the intersection point given by the equations.

⇒ (x, y) ⇒ (-1, -4)

Therefore, the point of intersection is (-1, -4).
