How do I solve for X?

ladessa [460]

All the angles should add up to 360°.

8x+10x+9+21x-12+90=360°

Group like terms together.

So,8x+10x+21x+9+90-12=360

39x+87=360

39x=360-87

39x=273

x=7

6,666,666×666,666 /1+2+3+4+5+6+5+4+3+2+1 − 777,777×777,777/1+2+3+4+5+6+7+6+5+4+3+2+1

Answer:

111111 $\times$ 1111110 is the simple expression.

Step-by-step explanation:

The expression to be solved:

$\dfrac{6,666,666\times666,666 }{1+2+3+4+5+6+5+4+3+2+1} - \dfrac{777,777\times777,777}{1+2+3+4+5+6+7+6+5+4+3+2+1}$

First of all, let us solve the first term:

$\dfrac{6,666,666\times666,666 }{1+2+3+4+5+6+5+4+3+2+1}\\\Rightarrow \dfrac{6666666\times666666 }{36}\\\Rightarrow \dfrac{6666666\times666666 }{6\times 6}\\\Rightarrow 1111111\times 111111$

Now, the right term:

$\dfrac{777777\times777777}{1+2+3+4+5+6+7+6+5+4+3+2+1}\\\Rightarrow \dfrac{777777\times777777}{49}\\\Rightarrow \dfrac{777777\times777777}{7 \times 7}\\\Rightarrow 111111 \times 111111$

So, the expression to be solved becomes:

$1111111\times 111111-111111\times 111111\\\Rightarrow 111111(1111111-1)\\\Rightarrow 111111\times 1111110$

F(x)=x^2 what is g(x)

MrRissso [65]

The answer is C. g(x) = (4x)^2

We can see the transformation applied to the function is a compression which means:

g(x) = f(c•x) , c > 1

We can find c using the point in the graphic of g(x), (1, 16)

so we can replace x=1 and g(x) = 16
g(x) = f(c•x)
g(x) = (c•x)^2
16 = (c•1)^2
16 = c^2
√16 = c
4 = c

Then we can replace c in the formula
g(x) = (4x)^2

- Please help this is a Rational Inequality problem

Katyanochek1 [597]

1. The solution for the equation is -16t² + 64t > 0

2. The interval notation for the equation is (0, 4)

Given,

The height of the building = 400 feet

A ball is thrown straight up from the top of the building.

The initial velocity of the ball = 64 feet/second

The height of the object is modeled by, s(t) = -16t² + 64t + 400

1. Solution for the equation:

s(t) > 400

So,

-16t² + 64t + 400 > 400

Add -400 to both sides

ie, -16t² + 64t + 400 - 400 > 400 - 400

We get,

-16t² + 64t > 0

2. Now find the interval notation for the equation:

-16t² + 64t > 0

Here, 64/16 = 4

So,

-16t (t - 4) > 0

Now,

t = 0 and t - 4 = 0

The interval notation for the equation is (0, 4)
