Answer:

x =-14     x=13

Step-by-step explanation:

Let x be the unknown number

x^2 +x = 182

Subtract 182 from each side

x^2 +x -182 = 182-182

x^2 +x -182=0

What two numbers multiply to -182 and add to 1

14*-13 = 182

14-13 =1

(x+14)(x-13) = 0

Using the zero product property

x+14=0  x-13 =0

x =-14     x=13

Which of the following transformations are used when transforming the graph of the parent function...
hram777 [196]

1. 1st transformation is translation the parent function y=\log_5x 6 units to the right to get the function y=\log_5(x-6).

2. 2nd transformation is reflection the function y=\log_5(x-6) over the x-axis. This transformation gives you the function y=-\log_5(x-6).

3. 3rd transformation is vertical stretch of the function y=-\log_5(x-6) by a factor of 2 to get the function y=-2\log_5(x-6).

Only last two are present in options, then

answer: C and D.

solong [7]
1.8:12.06=\dfrac{1.8}{12.06}=\dfrac{1.8\cdot100}{12.06\cdot100}=\dfrac{180}{1206}=\dfrac{180:6}{1206:6}=\dfrac{30}{201}=\dfrac{30:3}{201:3}=\dfrac{10}{67}

The number in each column are related. The goal is to determine how they are related, determine which numbers belongs in the bla
andre [41]

Answer:

If you cube the numbers in the left column, you get the numbers in the right column! We can figure this out by understanding that 1^3 = 1, 3^3 = 27, and 6^3 = 216. Then it all falls into place!

1 -> 1

2 -> 8

3 -> 27

5 -> 125

6 -> 216

11 -> 1331

8 -> 512

10 -> 1000

7 -> 343

14 -> 2744

p -> p^{2}

\sqrt{q} -> q

The value of x is: <br><br><br> A. 40 <br><br><br> B. 20 <br><br><br> C. 13
tangare [24]
Hey there!

Write a proportion. 8/5=32/x. Cross multiply. You get 8x=160. You have to isolate x, so divide each side by 8. X=20. Since x is by itself, you have your answer. The answer is B. Another way to do this is to see how much it takes to get from 8 to 32. You would multiply by 4. So multiply 5 by 4 to get 20.

I hope this helps!
