Hurry! pls!

the graph shows the acceleration of a racehorse taking off from a starting gate. by how much did the horse's speed increase between 4 seconds and 6 seconds?

a) 20 m/s

b) 27 m/s

c) 45 m/s

d) 65 m/s

The answer is 27

Step-by-step explanation: The reason it is 27 is because in between the 4-6 if you count it from 19-27 so you would get your answer 20 is to less 45 is to much and 65 is greater then 4-6 seconds. Please mark brainiest.

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
