Answer:
X= 1/9 decimal form x=0.1
Step-by-step explanation:
3^x+1=3²(5x)
x+1 =2(5x)
solve for x
x=1/9
Exact form: x= 1/9
Decimal form x=0.1
-7 is the slope of the linear function represented in the table
Answer:
For the table on the left the rate of change is ![22.8](https://tex.z-dn.net/?f=22.8)
For the table on the left the rate of change is ![-2](https://tex.z-dn.net/?f=-2)
Step-by-step explanation:
The range of change is the slope. The slope can be found with the following formula:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
<u>For the table on the left</u>
Choose two points. In this case you can choose (-1,-24), (4,90)
You can say that:
![y_2=-24\\y_1=90\\\\x_2=-1\\x_1=4](https://tex.z-dn.net/?f=y_2%3D-24%5C%5Cy_1%3D90%5C%5C%5C%5Cx_2%3D-1%5C%5Cx_1%3D4)
Substituting these values into the formula, you get:
![m=\frac{-24-90}{-1-4}\\\\m=22.8](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-24-90%7D%7B-1-4%7D%5C%5C%5C%5Cm%3D22.8)
<u>For the table on the right</u>
Choose two points. You can choose (3,-6), (-6,12)
You can identify that:
![y_2=-6\\y_1=12\\\\x_2=3\\x_1=-6](https://tex.z-dn.net/?f=y_2%3D-6%5C%5Cy_1%3D12%5C%5C%5C%5Cx_2%3D3%5C%5Cx_1%3D-6)
Substituting these values into the formula, you get:
![m=\frac{-6-12}{3-(-6)}\\\\m=-2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B-6-12%7D%7B3-%28-6%29%7D%5C%5C%5C%5Cm%3D-2)
Hello! For this question, we are looking for the percent of change. The formula for percent of change is change/original = x/100, where change is tge difference between two numbers, and the original is the previous number. 136,500 - 130,000 is 6,500. The original number is 130,000. It would be set up like this:
6,500/130,000 = x/100
Let's cross multiply the values. 6,500 * 100 is 650,000. 130,000 * x is 130,000x. That makes 650,000 = 130,000x. Now, divide each side by 130,000 to isolate the x. 130,000x/130,000 cancels out. 650,000/130,000 is 5. There. x = 5% increase. The answer is A: 5%.
