Answer:

Option A is correct

Step-by-step explanation:

because,

2b+b and 3b

if b= 1

2(1)+1 and 3(1)

2+1 and 3

3 and 3

Hence Both have same value if b=1

What is its domain?
What is its range?

Write the answer in interval notation.

Answers

Answers:

Domain = [-3, 3]

Range = [-1, 2]

=============================================

Explanation:

The domain is the set of all allowed x inputs. Visually, the left-most point is when x = -3, so -3 is the smallest allowed x input. We have a closed circle at this endpoint, so this endpoint x value is included. In contrast, if you had an open circle, then you would exclude the endpoint.

Similarly, we have a closed endpoint at the other side as well when x = 3. This is the largest allowed x value. The domain is the set of x values such that [tex]-3 \le x \le 3[/tex] meaning x is between -3 and 3, including both endpoints. This translates to the interval notation of [-3, 3]. The square brackets say "include the endpoint".

------------

The range is the set of possible y outputs of a function. The lowest the function goes is when y = -1, and the highest is when y = 2. We include both endpoints. The range as a compound inequality is [tex]-1 \le y \le 2[/tex] which converts to the interval notation of [-1, 2]

Step-by-step explanation:

in the bag, there are certain number of toy- blocks with alphabets A,B,C and D written on them. The ratio of blocks A:B:C:D is 4:7:3:1. if the number of A blocks is 50 more than the number of C blocks, what is the number of B blocks?​

Answers

Given, the ratio of blocks A, B, C,D are in the ratio 4:7:3:1

Let us consider the common ratio to be ‘x’.

So, toy blocks with alphabet A is 4x and

toy blocks with alphabet B is 7x and

toy blocks with alphabet C is 3x and

toy blocks with alphabet D is x


Again, the number of ‘A’ blocks is 50 more than the number of ‘C’ blocks.

As no. of ‘A’ and ‘C’ blocks are 4x and 3x respectively.

So,

4x=50 + 3x

x=50

Thus, the number of ‘B’ blocks is 7x = 7(50) = 350

350 is the required number.

9514 1404 393

Answer:

  350

Step-by-step explanation:

There are 4 ratio units of A blocks and 3 ratio units of C blocks, so 1 more ratio unit of A blocks than of C blocks. That 1 ratio unit corresponds to 50 blocks, since there are 50 more A blocks than C blocks.

There are 7 ratio units of B blocks, so the number of B blocks is ...

  7×(50 blocks) = 350 blocks . . . . . number of B blocks

d = 3

an = 43

an = a + (n - 1)d

43 = 4 + (n - 1) 3

43 = 4 + 3n - 3

43 = 1 + 3n

43 - 1 = 3n

3n = 42

n = 42 ÷

n = 14

So, 14th term is 43

Answers

Answer:

E. (7, 5)

Explanation:

vertices C and D have the same coordinate x and x of D = 7

hence

x of C = 7

vertices A and D have the same coordinate y and y of D = 2

hence

m = 2

and

m+3 = 2+3 = 5

and since vertices B and C have the same coordinate y and y of B = 5

hence

y of C = 5

thus

coordinates x, y of C: (7, 5)
