Answer:

Third choice: {3, 4, 6, 7, 9}

Explanation:

Please, find the Venn diagram attached.

You have to find the set that represents the union of the set M and N (M ∪ N). That is a set with the elements that belong either to set M or set N.

The elements that belong to the set M are the numbers inside the circle M: 3, 4, 7 and 9.

The elements that belong to the set N are the numbers inside the circle N: 4, 6 and 7.

The complete list of the numbers in the union set is 3, 4, 6, 7, and 9, as you must not repeat the elements that belong to both sets.

So, the set that represents M ∪ N is the third option {3, 4, 6, 7, 9}.

Step-by-step explanation:

tony is 5 years younger than Marvin's age 1 year from now.

t = (m+1) - 5

t = m - 4

6 years ago tony was half as old as marvin was then.

t - 6 = 1/2(m - 6)

Get rid of the fraction, multiply both sides by 2

2(t-6) = m - 6

2t - 12 = m - 6

2t = m - 6 + 12

2t = m + 6

from the first statement, replace t with (m-4)

2(m-4) = m + 6

2m - 8 = m + 6

2m - m = 6 + 8

m = 14 is Marvin's present age

how old is tony now?

t = 14 - 4

t = 10 yrs is tony's age

A bookcase has two shelves. The top shelf has 10 more than 1/3 the number of books on the bottom shelf. There are 12 books on th

kobusy [5.1K]

Answer: b.14

Step-by-step explanation:

We have two shelves, the top shelf $s_{t}$ and the bottom shelf $s_{b}$ .

Now, firstly we are told the top shelf has 10 more than 1/3 the number of books on the bottom shelf. This can be expressed as:

$s_{t}=10+\frac{1}{3}s_{b}$ (1)

Then, we are told there are 12 books on the bottom shelf:

$s_{b}=12$ (2)

Substituting (2) in (1):

$s_{t}=10+\frac{1}{3}(12)$ (3)

$s_{t}=10+\frac{12}{3}$ (4)

$s_{t}=14$ (5) This is the number of books on the top shelf

Hence, the correct option is b.

suppose a parabola has an axis of symmetry at x=-2, a maximum height of 8, passes through the point (-6, 2). Wrire the equation

Virty [35]

Answer:

y = -3/8(x + 2)^2 + 8

Step-by-step explanation:

vertex form is

y = a(x - b)^2 + c where a is a constant and (b,c) is the vertex.

The maximum is at (-2, 8) because x 8 = height and x =-2 is equn. of symmetry

So here we have

y = a(x - (-2))^2 + 8

y = a(x + 2)^2 + 8

Now at the point (-6, 2):

2 = a(-6+2)^2 + 8

2 = 16a + 8

16a = -6

1 = -3/8.

So our equation is y = 3/8(x + 2)^2 + 8
