y = 3x - 7

Add 7 to both sides

7 + y = 3x

Divide both sides by 3

(7 + y)/3 = x

A man drops a ball from the top of a 300 foot cliff. The height of the falling ball is modeled
netineya [11]

Answer:

The ball reaches 44 ft above the ground after 4 sec.

Step-by-step explanation:

Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t.  Indicate exponentiation with " ^ "

-16t^2 + 300 = 44 becomes

-16t^2 + 256 = 0, or 16t^2 = 256.  Then, taking the square root of both sides, we get:

4t = 16, or t = 4 sec.  The ball reaches 44 ft above the ground after 4 sec.

Given that f(x) = x2 − 3x + 3 and g(x) = the quantity of x minus one, over four, solve for f(g(x)) when x = 5.
Katena32 [7]

g(x) = the quantity of x minus one, over four

g(x) = (x-1)/4

g(5) = (5-1)/4

g(5) = 4/4

g(5) = 1


f(x) = x2 − 3x + 3

f(g(5)) =1^2 − 3(1) + 3

f(g(5)) = 1 - 3 + 3

f(g(5)) = 1

A child must be at least 36 inches, but no more than 48 inches to ride. Write the compound inequality to represent the heights w
NeX [460]

Answer:

36≤x≤48

Step-by-step explanation:

Let x represents the height of the child if a child must be at least 36 inches, this means that the child can has a height greater than or equal to 36in. This is expressed as;

x≥36

If the same child has height of no more than 48in, this can be expressed as;

x≤48

Combining both inequality

If x ≥36, this means 36≤x

Combining with x≤48 will give the compound inequality;

36≤x≤48

A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than
Dima020 [189]

Answer:

  • first side: 55 cm
  • second side: 60 cm
  • third side: 50 cm

Step-by-step explanation:

The problem statement gives all the side lengths in terms of that of the second side. Let s represent the length of the second side in cm. Then the length of the first side is (2s-65), and the length of the third side is (s-10). The perimeter is the sum of all the side lengths:

  165 = (2s -65) +s +(s-10)

  165 = 4s-75

  240 = 4s

  60 = s . . . . . . . . second side

  2s-65 = 55 . . . . first side

  s-10 = 50 . . . . . . third side

In order, the side lengths are 55 cm, 60 cm, 50 cm.
