3. Jeremy stands on the edge of a river and throws a rock into the water. The rock leaves his hands at a height of 5 feet above the water. It moves upward and then
down before splashing into the center of the river. The rock is 20 feet in the air
when it is 10 feet away from Jeremy. The rock reaches the highest point along its
path when it is horizontal distance of 20 feet from his hand and 25 feet above the
water.
Write a function h to represent the height of the rock in terms of its distance, d,
from Jeremy's hand.

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

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

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.

just pick what you think i need more time let me know if this
