Answer:

Undetermined x=x

Step-by-step explanation:

First, you need to simplify each side by combining like terms:

(5x - 7x)(+3-4) = (2x - 4x) +1

-2x - 1 = -2x + 1 is your simplified expression.

After adding 1 to both sides, you're left with: -2x = -2x

You <em>can</em> divide both sides by -2, you'd get: x = x

Therefore, it's undetermined. Meaning, there are no possible solutions or there's infinite solutions. In this case, there's infinite solutions.

In the diagram, is the perpendicular bisector of and is also the angle bisector of . If m = x, which quantity is equal to sin ?

earnstyle [38]

Given that line PN is a perpendcular bisector of line AB, then angles APN and BPN are equal to 90 degrees each.

Also, given that line PN is an angle bisector to angle CPD and angle CPD measures x, then the measure of angle DPN is $\frac{1}{2} x$ .

Thus, the measure of angle DPB = angle BPN - angle DPN
$=90- \frac{1}{2} x$

Therefore,
$\sin DPB=\sin\left(90- \frac{1}{2} x\right) \\ \\ =\sin(90)\cos\left(\frac{1}{2} x\right)-\sin\left(\frac{1}{2} x\right)\cos(90) \\ \\ =\cos(\frac{1}{2} x)$

a waiter had nine tables he was waiting on, with seven women and three men at each table. how many customees total did the waite

Greeley [361]

Since each table had 7 women and 3 men at each table, that would mean each table has 10 people. Since there are 9 tables he was waiting on, and 10 people at each table, multiply 9 x 10, and you will find that he served 90 people in total.

If the gradient of the line joining the points (-3,-7) and (4,p) is 3/5, find the value of P.

adelina 88 [10]

Given:

Two points (-3, -7) and (4, p).

To find the value of P if the gradient is 3/5:

The gradient in a linear equation is the same thing as the slope of the line.

So, the formula is,

$\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \frac{3}{5}=\frac{p-(-7)}{4-(-3)} \\ \frac{3}{5}=\frac{p+7}{7}\Rightarrow3(7)=5(p+7) \\ 21=5p+35 \\ 5p=21-35 \\ 5p=-14 \\ p=-2.8 \end{gathered}$

Hence, the value of p is -2.8.
