1..) 2x +15 = 35 

Mathematics
1 answer:
Masja [62]2 years ago
3 0

Answer:

1) x=10

2) x=3

Step-by-step explanation:

1)

2x+15=35

Subtract 15 from both sides

2x=20

Divide both sides by 2

x=10

2(10)+15=35

20+15=35

35=35

this shows that 10 is the right answer

2)

7x-3=18

Add 3 to both sides

7x=21

Divide both sides by 7

x=3

7(3)-3=18

21-3=18

18=18

this shows that 3 is the right answer

Hope this helps

If the subspace of all solutions of Ax 0 has a basis consisting of vectors and if A is a ​matrix, what is the rank of​ A
Nuetrik [128]

Question: If the subspace of all solutions of

Ax = 0

has a basis consisting of vectors and if A is a ​matrix, what is the rank of​ A.

Note: The rank of A can only be determined if the dimension of the matrix A is given, and the number of vectors is known. Here in this question, neither the dimension, nor the number of vectors is given.

Assume: The number of vectors is 3, and the dimension is 5 × 8.

Answer:

The rank of the matrix A is 5.

Step-by-step explanation:

In the standard basis of the linear transformation:

f : R^8 → R^5, x↦Ax

the matrix A is a representation.

and the dimension of kernel of A, written as dim(kerA) is 3.

By the rank-nullity theorem, rank of matrix A is equal to the subtraction of the dimension of the kernel of A from the dimension of R^8.

That is:

rank(A) = dim(R^8) - dim(kerA)

= 8 - 3

= 5

6) If 1 Inch = 2.54cm, then set up and solve a proportion that finds how many
Roman55 [17]

Answer:

3.93700787402, almost  4

Step-by-step explanation:

10 ÷ 2.54

3 × 2.50 = 7.50

3 × 0.04 = 0.12

7.50 + 0.12 = 7.65

7.65 + 2.54 = 10.19

The precise number is use calculator.

Pavel [41]
If you have a picture that shows line c on a graph, you could find your y-intercept or b. If not, you need the y-intercept to make an equation.
