Substitute y = 1/5 x + 1 into x + 5y = -15

x + 5y = -15

x + 5(1/5 x + 1) = -15

x + x + 5 = -15

2x = -20

x = -10

Plug in x = -10 into y = 1/5 x + 1

y = 1/5 (-10) + 1

y = -2 + 1

y = -1

(-10 , -1)

Answer is the last one

(-10 , -1)

(The answer I have marked was random) Please tell me the answer and explain. Thanks.

Formula for probability
$\frac{given \: number}{total \: number} \times 100$
Theorically probability will be equal for all cases, that means each case will have a 25% chance
Now we will find the probability experimentally
Given number = 28
Total number = 100
28/100 × 100 = 28%

Since Theorically it is 25 and experimentally it is 28, The experimental probability is 3 % higher
Therefore the answer is the first option (the one u marked randomly)
Hope I helped... Please give me Brainlest answer

Micah rows his boat on a river 4.48 miles downstream, with the current , 0.32 hours. He rows back upstream the same distance, ag

pentagon [3]

Short Answer: Current speed = 3 miles per hour.
Givens
Downstream
d = 4.48 miles
t = 0.32 hours.
c = ??
r_boat = ??

Upstream
d = 4.48 miles
t = 0.56 miles
c = ??
r_boat =??

Equations.
Since the distances are the same, you can equate the distances and come back to them later.
d = r*t
(r - c) * 0.56 = (r + c) * 0.32 This will give you r in terms of c. Notice the minus sign on the left. It's there because the current is going against you, slowing you down.
Remove brackets
0.56r - 0.56c = 0.32r + 0.32c Add 0.56c to both sides.
0.56r = 0.32r + 0.32c + 0.56c
0.56r = 0.32r + 0.88c Subtract 0.32r from both sides.
0.56r - 0.32r = 0.88c
0.24r = 88c Divide by 0.24
r = 0.88/0.24 c
r = 3 2/3 c

Now we have enough information to solve for c

4.48/(r + c) = 0.32
4.48 = 0.32 * (r + c) Substitute r = 3 2/3c into this equation.
4.48 = 0.32 * (3 2/3c + c) Add c and 3 2/3c together.
4.48 = 0.32 * (4 2/3c) Change 4 2/3 to  14/3
4.48 = 0.32 * 14/3 c
4.48 = (4.48 / 3 ) * c
4.48 = 1.493333333 c Divide 4.48 by 1.493333333
c = 4.48 / 1.4933333
c = 3 mph <<<<<<<<<<<<<<Answer
