Kerille is reading a book at the rate of 4.5 pages per minute. What ordered pair on a graph of his reading rate would represent
viva [34]
This is a linear equation y = mx, where:
m= slope or reading rate:
x = the number of minutes
y = the number of pages read.

So the equation becomes: y = 4.5.x
How many minutes it will take to read 90 pages (y):
90 = 4.5.x    or x = 90/4.5  and x = 20 minutes
So the ordered pair will be (20,90)

4x + 3y = 16<br> 7x+6y=31<br> O A. (1,3)<br> B. (1.4)<br> C. (4,0)<br> OD. (4,3)<br> SUBMIT
klasskru [66]

Answer:

B

Step-by-step explanation:

Given the 2 equations

4x + 3y = 16 → (1)

7x + 6y = 31 → (2)

Multiplying (1) by - 2 and adding to (2) will eliminate the term in y

- 8x - 6y = - 32 → (3)

Add (2) and (3) term by term

- x = - 1 ( multiply both sides by - 1 )

x = 1

Substitute x = 1 in either of the 2 equations and solve for y

Substituting in (1)

4(1) + 3y = 16

4 + 3y = 16 ( subtract 4 from both sides )

3y = 12 ( divide both sides by 3 )

y = 4

Solution is (1, 4 ) → B

Select ALL the sets that are the three side lengths of right triangles.
Gre4nikov [31]

Answer: It would be C and D

Step-by-step explanation:

By the phythagorean theorem, the 2 legs would equal to the hypothesize.

Choice A would not form a triangle.

Choice B does not follow the pythagorean theorem. 84 plus 16 does not equal 100.

Choice C does. 8 + 121 = 129.

Choice D does. 1 + 3 = 4.
