If you would like to solve the equation a^2 - 8*a + 12 = 0 for a, you can calculate this using the following steps:
a^2 - 8*a + 12 = 0
(a - 6) * (a - 2) = 0
1. a = 6
2. a = 2
The correct result would be B; 2, 6.
Answer:
2
Step-by-step explanation:
Given the average rate of change formula, we must first find the x and y values of the function.
We are provided with the two x values, 1 and 2. We now need to find the output, or y.
ƒ(x)=3^x-4x
ƒ(1)=3-4=-1
ƒ(2)=9-8=1
Then, we use the formula (ƒ(2)-ƒ(1))/x2-x1(subscripts here, in case you multiplied) which gets us 2/1, or 2. Therefore, the average rate of change(ARC) is 2. I believe you just need to find the output and subtract if they are exactly one whole number apart, but don't quote me on that.
Answer: 16-7

Hello!
To do seventh grade ratios, you take a ratio and turn it into a fraction. Look at this example problem. (v v v)
A boy has a spinner with three different colors, red green and blue. Find the ratio of red to green if spun 10 times. 3:5. It'd be 3/5 as a final result.
Hope this helps! ☺♥
Answer:
The freezing point of the water with the added potassium is 24 degrees Fahrenheit.
Step-by-step explanation:
To find the freezing point of the water with the added potassium, you need to subtract 8 degrees from the initial freezing point of water, This is because you know that after adding potassium to water, the freezing point went down by 8 degrees Fahrenheit. So you need to subtract 8 degrees from the initial freezing point of water (32 degrees Fahrenheit). 32º F - 8º = 24º F. So the freezing point of the water with the added potassium is 24 degrees Fahrenheit.
