Answer:

-X=9

Step-by-step explanation:

f(x)=-x-1

Plug in -10

-10=-x-1

add 1 to -10

-9=-x

which means -x=-9

to check, plug everything in

-10=-9-1

-10=-10

Find the greatest common factor of the expressions.<br> 5x^7, 30x

kogti [31]

To find the GCF (greatest common factor) we must find the largest thing that can go into both of them.

We cannot divide by any exponents because only one has them, however we can divide by 5x.

5x^7, 30x

x^7, 6

So, the GCF is 5x

Hope this helps,

1. What is the value of h? (1 point)

irinina [24]

The value of h is 11.3.

Solution:

Given data:

The triangle is a right triangle.

θ = 45° and opposite side of θ = 8

The value of sin 45° = $\frac{1}{\sqrt{2} }$

Using trigonometric formula,

$$\sin\theta=\frac{\text{Opposite side}}{\text{Hypotenuse}}$

$$\sin45^\circ=\frac{{8}}{h}$

$$\frac{1}{\sqrt{2} } =\frac{{8}}{h}$

Do cross multiplication.

$h = 8\sqrt 2$

h = 11.3

The value of h is 11.3.
