Answer:

the decimal measuring system based on the meter, liter, and gram as units of length, capacity, and weight or mass. The system was first proposed by the French astronomer and mathematician Gabriel Mouton (1618–94) in 1670 and was standardized in France under the Republican government in the 1790s.

How to you get the radical form?
Over [174]

Answer:

Note: this answer is kind of long so jump to picture to see a visual process.

In order to find the simplest radical form of a square root, you need prime factorize the number. In order to do this, you take a number and divide it by different prime numbers until all of its factors are now prime. We will use 24 as our example. 24 divided by 2 (which is prime) is 12. 12 divided by 2, is 6. 6 divided by 2 is 3. Therefor, our prime factorization of 24 is 2^3 * 3, which basically means 8 * 3. Then, take take out pairs of the same number and put on the OUTSIDE of the root. However, make sure that it is NEXT to the square root and not inside the mini hook that the square root makes. This means that that number is multiplying the square root of the number. Now, the only pair in this prime factorization is 2, so take two out of the prime factorization and that leaves us with square root 6 times 2, which is the answer.

Also, when taking out pairs, only take one number from the pair (in this case 2) and put it on the outside. If there is another pair, multiply that number by the other number. So if there was a pair of 3 and a pair of 2, take out 1 three and 1 two and multiply them and put on the outside.

Slope intercept! Please help! Will mark brainliest.
avanturin [10]

3) y = -\frac{1}{2}x + 3

Slope-intercept form is y = mx + b when m is the slope and b is the y-intercept

b = 2 (line hits y-axis at 2)

m = \frac{rise}{run} or\frac{change.in.y}{change.in.x} so \frac{1}{2} and the line is negative, so -\frac{1}{2}

Write our equation by putting the parts together, and we get:

y = -\frac{1}{2}x + 3

4) y =  -\frac{2}{3}x - 1.67

Point slope form is y - y1 = m (x - x1) when y1 is the y coordinate of the point, m is the slope, and x1 is the x coordinate of the point

y - y1 = m (x - x1)

Finding the slope (same as above) results in -\frac{2}{3}
