Can someone please help me with all of these. And thank you.

Answer/Step-by-step explanation:

1. x = -3.6

Add 1 on both sides.

18x = 23x + 18

Subtract 23x on both sides.

Combine like terms.

Divide the answer.

-5x = 18

x = -3.6

2. x = 11/3 (2.66666...)

Add 5 on both sides.

6x = 3x + 11

Subtract 3x on both sides.

Combine like terms.

Divide the answer.

3x = 11

x = 11/3

3. x = 23

Subtract 12 on both sides.

5x = 6x - 23

Subtract 6x on both sides.

Combine like terms.

Divide the answer.

-x = -23

x=23

(that's all.)

Exponential function

laiz [17]

A typical exponential function is y=a $b^{x}$
when x=3.5, y=16.2
when x=6, y=3936.6
plug these values into the exponential function:
16.2=a $b^{3.5}$
3936.6=a $b^{6}$
divide the second equation by the first to eliminate a:
243= $b^{(6-3.5)}$
log both sides: log243=2.5logb
logb=log243/2.5
use your calculator to find b: b=3.6
plug b=3.6 in the first equation to find a:
16.2=a $* (3.6)^{3.5}$
a=0.183

please double check my calculation

What is the answer for this Evaluate 3|-3|.

zhenek [66]

Answer: 9

Concept:

Here, we need to know the idea of absolute value.

The absolute value of a number or integer is the actual distance of the integer from zero, in a number line.

There are no negatives in absolute value. So in practice "absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive.

Solve:

Given

3 |-3|

Expand absolute value sign, which means making [-3] positive

= 3 × (3)

Simplify by multiplication

= $\boxed{9}$

Hope this helps!! :)

Find the length of dm in the given fig.

lesya692 [45]

Answer:

$DM=12$

Step-by-step explanation:

(Let the point where the altitude from $D$ intersects $AB$ be called as point $E$ .) First, let's find the area of parallelogram $ABCD$ . The area of a parallelogram is simply $b*h=bh$ , where $b$ is the parallelogram's base and $h$ is the parallelogram's height. If we let $AB$ and $DE$ be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram $ABCD$ will be $AB*DE=15*8=120$ .

Now, how does this information matter, you might ask? Well, we can take either $AB$ or $CB$ to be the base and either $DE$ or $DM$ to be the height. In this case, let's take the latter two options, as we are looking to find the length of $DM$ .

Therefore, we know that the area of parallelogram $ABCD$ can also be found by calculating $CB*DM$ . Since we know the values of the area and $CB$ , we can write the following equation to solve for $DM$ :
