In the diagram AB is parallel to CD. Calculate the value of A ?
olga55 [171]

The image of the diagram is missing, so i have attached it.

Answer:

a = 30°

Step-by-step explanation:

From the diagram attached, we can see that the 2 angles a and 5a are interior supplementary angles.

The sum of interior supplementary angles is 180°

Thus;

5a + a = 180

6a = 180

a = 180/6

a = 30°

Find the equation in slope-intercept form of the line parallel to y = 4x + 23 and passes through the point (2,3).
kupik [55]

Answer: y=4x-5

Step-by-step explanation:

The slope of y=4x+23 is:4 m=4  

The parallel line needs to have the same slope of 4

Solve it using the "point-slope" equation of a line:   y− y1 = 2(x − x1)

substitute or put in the point (2,3):

y − (3) = 4(x − 2)

y - 3 = 4x - 8      

 put it in slope intercept form y = mx + b  

y  = 4x − 5

Brainly didnt let me copy and paste lol check the picture
lozanna [386]

Answer:

A 5040

B 35

Step-by-step explanation:

A  There are 7 ways to put the first picture.  There are 6 pictures left and 6 ways to put the 2nd picture.  There are now 5 pictures left and 5 ways to put the 3rd picture.  And so on

7 * 6*5*4*3*2*1

5040

B  If we can only have 3 pictures and order does not matter

7 choices for the first * 6 *5

But

We have to take into account order

The first picture can go into 3 slots, the second into 2 and the third 1 so divide by 6

(7*6*5)/ (3*2*1)

35

What is 4C (matrix) ?
Cerrena [4.2K]
The 4C matrix is obtained when all elements of matrix C are multiplied by 4. It <span>has all the same elements as C, only multiplied by 4.
Let's analyze all matrices
A. Not all elements of A can be divided by 4 (3 can not be divided by 4, the solution is not a whole number).
B. All elements of matrix B can be divided by 4, which means that B is a $C matrix (there is a matrix C which multiplied by 4 gives the matrix B).
C. Not all elements of C can be divided by 4.
D. Not all elements of D can be divided by 4.

Solution: B
