Answer:

-226,981

Step-by-step explanation:

This is how you do it.

First, you do 3-2 which is 1.

Then, you do 3-4 to the 3rd power which is -61.

After, you do 1*-61 because there are parenthesis, which equals -61.

Then, you do -61, which is the total of everything in parenthesis, and do it times the power of 3 to get -226,981.

Hope it helps!!^_^

First, you have to solve what is the () which is 3-4.
Then you should get -1
Then you (-1)^3
That should equal -1
Then you do 2 x (-1)
That should equal +2
Then you add 3+2
That should equal 5
Then you do (5)^3
Which should equal 125

WILL MARK BRAINLIEST!!!!!!!!!!!!!!!!!! Why would someone choose to use a graphing calculator to solve a system of linear equatio

ohaa [14]

Answer:

A graphing calculator is more accurate than graphing by hand. If the slope and/or y-intercept is a fraction or decimal, it is more difficult to accurately graph by hand.

Find the vertex of the graph of f(x) = x2 + 4x - 5.

Fofino [41]

You can solve this in two ways.

1. Graphical. Plot the graph for x between -5 and 1 (see attachement).
The vertex of the graph is the peak of the curve, which has the coordinates x=-2, y=-9.

2. Analytical. Calculate the derivative of the function f(x)
$\frac{df}{dx}=2x+4$
Solve the equation:
$2x+4=0$
will give the solution x=-2.
Replace x=-2 in the f(x) function and you'll get the value of y:
$(-2)^2+4 \cdot (-2)-5=4-8-5=-9$

You get the same answer: x=-2, y=-9

So the answer is
B. (-2, -9)

Solve 169x^2-42.25=0 by using square roots? NEED HELP!!!

jekas [21]

Answer:

x = 1/2 , x = -1/2

Step-by-step explanation:

Given equation;

169x² - 42.25

Find:

Solution of equation using square root

Computation:

169x² - 42.25

We know that 13² = 169 and 6.5² = 42.25

So,

[13x]² - [6.5]²

a² - b² = (a + b)(a - b)

So,

[13x]² - [6.5]² = [13x + 6.5][13x - 6.5]

So,

13x + 6.5 = 0 , 13x - 6.5 = 0

x = 6.5 / 13 , x = -6.5 / 13

x = 1/2 , x = -1/2
