Answer:
4 and 20
Step-by-step explanation:
The sum of two numbers is 24.
One of the numbers is 5 times larger than the other.
Let x be the first number.
Let y be the second number.
x + y = 24
x = 5y
Put x as 5y in the first equation.
5y + y = 24
6y = 24
y = 4
Put y as 4 in the second equation.
x = 5(4)
x = 20
Answer:
8 seconds
Step-by-step explanation:
Given
h = - 5t² + 40t
When the object hits the ground then h = 0
Substitute h = 0 into the function and solve for t
- 5t² + 40t = 0 ← factor out - 5t from each term
- 5t(t - 8) = 0
Equate each factor to zero and solve for t
- 5t = 0 ⇒ t = 0
t - 8 = 0 ⇒ t = 8
t= 0 denotes the time of launch
t = 8 denotes the time it hits the ground
Answer:
Always
Step-by-step explanation:
Coplanar lines are lines that intersect making intersecting lines always coplanar.
4y ≥ 3x + 2
Plugging in the values in the options, then the required values are when x = 6 and y = 5, then
4(5) ≥ 3(6) + 2
20 ≥ 18 + 2
20 ≥ 20
Combining like terms would be defined as multiplying each term in a set of parentheses by the number outside of the parentheses.
