-3x=2x+19 solve for x

1 answer:

8 0

-3.8
-3x=2x+19
First you need to get rid of 2x so subtract 2x from each side
You should have -5x=19
Then divided by -5
And you get x=-3.8
I hope this is correct hope it help

The length of FD = 0.76 feet.

Step-by-step explanation:

Given that in ΔDEF, the angle F measures 90° and the angle D measures 83° and EF=6.2 feet

To find the length of FD, let us use the tangent function. The tangent of an angle is the length of opposite side divided by the length of the adjacent side.

$\tan \theta=\frac{o p p}{a d j}$

From the given data, θ=83°, $o p p=6.2$ and $a d j=x$

Substituting these values in the tangent formula, we get,

$\begin{array}{r}{\tan \theta=\frac{o p p}{a d j}} \\{\tan 83^{\circ}=\frac{6.2}{x}}\end{array}$

Using calculator, the value of $\tan 83^{\circ}=8.14$ and substituting and solving the equation, we get,

$\begin{aligned}8.14 &=\frac{6.2}{x} \\x &=\frac{6.2}{8.14} \\x &=0.76\end{aligned}$

Thus, the length of FD = 0.76 feet.

For the function f(x) = (x − 2)2 + 4, identify the vertex, domain, and range.

DanielleElmas [232]

I think the correct answer from the choices listed above is option D. For the function f(x) = (x − 2)2 + 4, the vertex is (2, 4), the domain is all real numbers, and the range is y ≥ 4. The domain is all x-values available for the function and the range are the y values and in this case it should be greater than or equal to 4. Hope this answers the question.

An 8.5 centimeter green bean pod contains peas that average

Aleksandr-060686 [28]

Answer:

18 peas

Step-by-step explanation:

18.89 peas are in the pod, or about 18 peas, because you can divide 8.5 by 0.45 and get 18.8 recurring, or about 18.89, or 18
