Have you learned slope yet? Pick two points from the graph and do x-y on the top and x-y on the bottom. That would give you your slope then you can graph it. For example (-2,-1) (-1,1)
-2-(-1)
-1-1
Then that would give you -1/-2 so technically -1/2<< this is what you graph

12) 12, 8

12 - 8 = 4

12 + 8 = 20

Answer: 4 < x < 20

13) 11, 3

11 - 3 = 8

11 + 3 = 14

Answer: 8 < x < 14

Hope this helps :)

Write an equation or inequality to represent the scenario:

aniked [119]

<h3>The value of x is equal to 1.</h3><h3>6(x + 2) = 20x - 2</h3>

Distributive property.

6x + 12 = 20x - 2

Add 2 to both sides.

6x + 14 = 20x

Subtract 16x from both sides.

14 = 14x

Divide both sides by x.

x = 1

What’s the answer to the top question and steps how to solve?

Leviafan [203]

Answer:

-3.69

Step-by-step explanation:

Exponential equations can be solved by taking Ln (natural logarithm) of both sides. The rule we need to know is:

$Ln(a^b)=bLn(a)$

Now lets work out this problem:

$16^{2x+3}=13^{x-1}\\Ln(16^{2x+3})=Ln(13^{x-1})\\(2x+3)Ln(16)=(x-1)Ln(13)$

Using calculator, we take the values of Ln 16 and Ln 13 as:

Ln 16 = 2.7726

Ln 13 = 2.5649

Now, we can solve for x:

$(2x+3)Ln(16)=(x-1)Ln(13)\\(2x+3)2.7726=(x-1)2.5649\\5.5452x+8.3178=2.5649x-2.5649\\2.9803x=-10.8827\\x=-3.69$

x is -3.69 (rounded to 2 decimal places)
