Set contain all the elements present in both the sets.

Step-by-step explanation:

Definition:

The union of two mathematical sets can be defined as the set that consists of all the elements present in both the sets without the repetition of elements.

Consider, A and B be the sets.

A = {1,7,5,6,0}

B = {2,3,4,5,6}

U is the symbol of union of sets, so A U B = {1,2,3,4,5,6,7,0}

Here 5 and 6 are the elements present in both the sets, so written only once in the set of A U B.

Jeo is comparing the price of different boxes of cereal. One box has 16 oz. and costs $3.50. Another costs $3.89 for a 24 oz. bo

velikii [3]

Answer:

The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.

Step-by-step explanation:

☆Let's solve using proportion.

☆One box:

$\frac{16 \: oz.}{3.50 \: dollars} = \frac{1 \: oz.}{x} \\ \\ \frac{3.50}{16} = \frac{16x}{16 } \\ \\ 0.22 = x$

☆Another box:

$\frac{24 \: oz.}{3.89 \: dollars} = \frac{1 \: oz.}{x } \\ \\ \frac{3.89}{24} = \frac{24x}{24} \\ \\ x = 0.16$

☆All we need to do is subtract: $0.22 - 0.16 = 0.06$

☆The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.

What is the slope of this graph? −1/3 3 1/3 −3

FromTheMoon [43]

I'm assuming there is probably a graph that goes with this problem so here is all the info I can give you with the four choices: If it is -1/3, the line will go DOWN 1, over 3 (just count on the graph) If it is 3, the line will go UP 3, over 1 If it is 1/3, the line will go UP 1, over 3 And if it it -3, it will go DOWN 3, over 1 (If the slope is 3 or -3, it would be quite steep compared to a slope of 1/3 or -1/3) Hope that helps!

Which is an equation in point slope form of the line that passes through the points 7,5 and -4,-1

Free_Kalibri [48]

Answer:

the second option is the correct one

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

To calculate m use the slope formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (7, 5) and (x₂, y₂ ) = (- 4, - 1)

m = $\frac{-1-5}{-4-7}$ = $\frac{-6}{-11}$ = $\frac{6}{11}$

Use either of the 2 points as (a, b)

using (- 4, - 1), then

y- (- 1) = $\frac{6}{11}$ (x - (- 4)), that is

y + 1 = $\frac{6}{11}$ (x + 4)
