What is the y-coordinate of the solution of the system? <br> {3x+10y=7, x-10y=29}
alexandr402 [8]
We know that:

3x + 10y = 7

We also know that:

x - 10y = 29

Which means that:

x = 29 + 10y

If, x = 29 + 10y,

3(29 + 10y) + 10y = 7

3*29 + 30y + 10y = 7

3(20+9) + 40y = 7

60 + 27 + 40y = 7

87 + 40y = 7

40y = 7 - 87

40y= -80

y=(-80)/40

y=-2

Answer y=-2.

If y=-2,

x-10(-2)=29

x+20=29

x=29-20

x=9

Let's see if these results are true:

3(9)+10(-2)=7

27-20=7 (Correct)

-----------

9-10(-2)=29

9+20=29 (Correct)

Answer once again:

y=-2

A college football coach wants to know if there is a correlation between his players’ leg strength and the speed at which they c
Leto [7]

Answer:

Please Read below! As a professional athlete, I think I can help. :)

Step-by-step explanation:

First, what is correlation? Correlation is when there is a mutual relationship or connection between two separate things. More studying, better grades. Less sleep, worse focus. In this instance, the football coach wants to see if better leg strength means a faster 40 yard sprint!

As a professional athlete, I can answer immediately that stronger legs, does generally mean a faster sprint. However, this does not mean better endurance in a long distance race!

So the correlation is: stronger legs = faster 40 yard run

A player that can reach 22 leg-presses is likely going to run a faster 40 yard dash, then someone who can only do 10 leg presses. At the same time, however, it's important to take into account the weight of each player, because the person with stronger legs, might have more weight to carry!

I cannot see any chart provided, but I'm going to assume that there is a positive linear graph, with equations being in slope form (y = mx + b).

Let me know if this helps! :)

6.A = 23 × 3 × 5 B = 22 × 3 × 52
frez [133]

Given:

The two numbers are

A=23\times 3\times 5

B=22\times 3\times 52

To find:

The highest common factor (HCF) of A and B

Solution:

We have,

A=23\times 3\times 5               ...(i)

B=22\times 3\times 52

All the factors of A are prime but the factors of B are not prime. So, it can be written as

B=2\times 11\times 3\times 13\times 2\times 2          ...(ii)

From (i) and (ii), it is clear that 3 is the only common factor of A and B. So,

HCF(A,B) = 3

Therefore, the highest common factor (HCF) of A and B is 3.
