Answer:

A. {-4, -3, 7, 8}

Step-by-step explanation:

The ordered pairs representing a function are always written ...

(input, output)

<h3>Inputs</h3>

The set of inputs for the given function is the list of first-numbers of the ordered pairs. Those numbers are -3, -4, 8, 7. When we express them as a set, we like to have the elements of the set in increasing order:

inputs = {-4, -3, 7, 8} . . . . . . matches the first choice

a solution of trioxonitrate (v) acid contained 0.67g in 100cm³. 31cm³ of this solution neutralized 25cm³ of a sodium trioxocarbo

FinnZ [79.3K]

Answer:

0.67 / 100 : 31^3 : 31^3 / 25cm^3

x 10

0.67 / 100 = 67 / 10000000 grams/cm : 29791 / 15625 / 29791

149253.731 : 0.52

divide by 1000

= 149.253731

= 149.3 kg

Ratio kg = 149.3 : 0.5

Step-by-step explanation:

Mole Ratio

The mole ratio compares the number of moles in a balanced equation.

This is the comparison between the coefficients in front of the chemical formulas.

If a formula lacks a coefficient, it is the same as saying there is 1 mole of that species.

Mole ratios are used to predict how much product a reaction forms or to determine how much reactant is needed to make a set amount of product.

Mole Ratio Units

Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2 to 1 mole of H2 is 3:1 or 3 mol O2: 1 mol H2.

Questions are in the image please help

For the first one use the slope formula: $m= \frac{ y_{2}- y_{1} }{ x_{2}- x_{1} }$
So for you that would look like this: $m= \frac{-4+1}{-2-7}= \frac{-3}{-9}= \frac{1}{3}$
For number 2, in order for a slope to be 0, it has to be a completely horizontal line with no steepness whatsoever. That can ONLY happen with lines that are "y=some constant with no x". So that answer has to be y = -5. For that last one, we have to use the slope-intercept form of a line and use the point they give us along with the slope to find the y-intercept, or the "b". That looks like this for us: $\frac{5}{6}=1(0)+b$ so b= 5/6. So our equation, fitting the slope and y intercept back in, gives us $y=x+ \frac{5}{6}$
