Does anyone know the answer to this? I can't understand why it isn't -7.​
faltersainse [42]

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

<h3>How to calculate the value?</h3>

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7

What do I use to find the answer?
Volgvan

Answer:

164 Yards

Step-by-step explanation:

With the information in this problem, we need to assume that triangle ADE and ABC are similar, otherwise we would not have enough information to solve it.

1. AE/DE=AC/BC (Since the triangles are similar, the corresponding parts will have the same ratio. In other words, you should be able to multiply the length of any side in one triangle by the same number and get a side length of the similar triangle.)

2. AE/DE=(AE+EC)/BC (Rewrite side length AC as the sum of its parts)

3. 230/120=(230+85)/BC (Insert the values given for each side length into the equation)

4. 230/120=315/BC (Add 230 and 85)

5. 230*BC=315*120 (Cross multiply)

6. BC=315*120/230 (Divide each side by 230 to isolate BC)

7. BC=164.347826... (Plug the equation into a calculator)

8. BC=164 (Since the problem asks to round to the nearest yard and the number in the tenths place is below 5, round your answer down to 164)

btw definitely ignore that guy posting links

please lmk if i made any errors, hope this helps!!!

The slope of MN is -6, which segments are parallel to MN, select each correct answer
hram777 [196]

Answer: The correct options are 1 and 2.

Explanation:

It is given that the slope of line MN is -6.

The slope of parallel lines are always equal. Therefore the line which have slope -6 is parallel to MN.

The formula to find the slope is,

m=\frac{y_2-y_1}{x_2-x_1}

Slope of PQ,

m_1=\frac{12-6}{4-5}= \frac{6}{-1}=-6

Slope of TU,

m_2=\frac{18-6}{6-8}= \frac{12}{-2}=-6

Slope of RS,

m_3=\frac{2-3}{7-1}= \frac{-1}{6}

Slope of WX,

m_3=\frac{0-6}{4-5}= \frac{-6}{-1}=6

Therefore, the correct options are 1 and 2.
