X=-9y+61/4.

Now substitute and solve
7(-9y+61/4)+6y=58

Combine like terms

-63/4y+427/4+6y=58
-63/4y+6y=-195/4
-39/4y=-195/4
-39y=-195
y=5 now input into other equation
4x+9*5=61
4x=16
x=4

if the graph of a quadratic function intersects with the x axis two times, how many solutions are there to the equation when set
konstantin123 [22]
Hello there!

This is a conceptual question about quadratic functions.

Remember that a solution of ANY function is where it intersects the x-axis, so if the quadratic function intersects the x-axis TWO times, this means that there are TWO real solutions.

Here's a list of things to remember that will help you out for quadratic functions...
•if a quadratic function intersects the x-axis twice, it has two real solutions.
•if a quadratic function intersects the x-axis once, it has one real solution and one imaginary solution.
•if a quadratic function intersects the x-axis zero times, it has zero deal solutions and two imaginary solutions.


Please NOTE: If you want to know how many solutions a polynomial function has, look at it's highest exponent. If it is 2, then it has 2 solutions whether they be real or imaginary. If it is 3, then it has 3 solutions.

Also, if one of the factors are the same for a polynomial function, the way it hits the x-axis changes! This is just some extra information to help you in the long run!


I hope this helps!
Best wishes :)

16 - 2r = -3r + 6r +1
Alona [7]

Answer:

r=3

Step-by-step explanation:

Simplify the expression

16-2r=3r+1

isolate r by adding 2r to both sides

16=5r+1

isolate the numbers by subtracting 1 from both sides

15=5r

divide both sides by 5 to completely isolate r

r=3
