PLEASE HELP! 30 POINTS AND WILL MARK BRAINLIEST. One group of hikers hiked at a steady rate of 6.5 kilometers per hour for 4 hours. The function f(t) represents the distance this group of hikers hiked in t hours. The graph shows the distance a second of hikers hiked, g(t) (in kilometers), as a function of t (in hours).

Write a rule for each function, and then compare their domain, range, slope, and y-intercept.

answer:

125 yards

explanation:

75+50=125. that is my answer

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

60: 45 =12: 9 =4: 3 so the answer is 4: 3
