Answer:
exactly one
Step-by-step explanation:
The system of linear equations have:
one solution, infinitely many solutions or no solution.
One solution if the lines intersect.
Infinitely many solutions if the lines are the same (overlap)
There is no solution if the lines are parallel (they do not have a common point).
In the graph, two lines intersect. Therefore, the system of equations has one solution (0, 3).
White roses - 5 30 40 50
Pink roses - 7 42 56 70
To solve, take the pink rose amount, divide by 7 to get the times given pink roses. Multiple it by 5 to get the amount of white roses.
For the last one, divide by 5 to get the amount of times given white roses. That’s ten times. Multiple it by 7, as that’s 10 times you get 7 pink roses, answer is 70.
Answer:
the third one
Step-by-step explanation:
im right
Answer:
Option (4)
Step-by-step explanation:
Given system of equations is,
y = -x²- 4x - 3
y = 2x + 5
To get the solution of the system of equations algebraically,
2x + 5 = -x²- 4x - 3
Now combine like terms onto one side of the equation.
-x² - (4x + 2x) - (3 + 5) = 0
x² + 6x + 8 = 0
Then factorize the equation,
x² + 4x + 2x + 8 = 0
x(x + 4) + 2(x + 4) =0
(x + 2) (x + 4) = 0
x = -2, 4
Option (4) is the answer.
