Choose the correct words from the drop-down menu to make a true statement about the system of equations.

Artist 52 [7]

Answer:

Step-by-step explanation:

Given the 2 equations

y = $\frac{1}{3}$ x + 2 → (1)

- x + 3y = 6 → (2)

Substitute y = $\frac{1}{3}$ x + 2 into (2)

- x + 3( $\frac{1}{3}$ x + 2) = 6 ← distribute left side

- x + x + 6 = 6, that is

6 = 6 ← True

This statement indicates the system has infinitely many solutions

Anit [1.1K]

Answer:

40oz glycol and water

10% is glycol

4oz is glycol

36oz is water

if glycol is to be added to make glycol 25% of all then

note: water does not change

100-25=75

water does not change so

36oz=75%

12=25%

there should be 12 oz of glycol total

explain the transformation needed to convert the following data to a linear data set {(1, 0.98), (2, 1.39), (3, 1.71), (4, 1.98)

The given numbers are a set of points. To convert this into a linear data set, you can do data fitting. The easiest way to do this is using a software. In this case, I used MS Excel. You plot the points and set a linear trendline. The linear equation for this set of data is: y = 0.286x + 0.784

You can refer to the image to further understand the procedure.
