Make quadratic equation with :-5 and -4
Answer:
x² + 9x + 20 = 0
Step-by-step explanation:
Given a solution x = - a for a quadratic equation then (x + a) is a factor
Here x = - 5 and x = - 4 , then corresponding factors are
(x + 5) and (x + 4)
The quadratic equation is then the product of its factors, that is
(x + 5)(x + 4) = 0 ← expand using FOIL
x² + 9x + 20 = 0

Which equation represents this graph?
what is the x and y equal in y=8x+1 and y=3x+26
Answer:
x=5, y=41
Step-by-step explanation:
Because both equations are equal to Y, you can set them equal to each other like this:
8x+1=3x+26
From here, solve for x:
1. 5x+1=26
2. 5x=25
3. x=5
Once you have x, plug it back in to one of the original equations:
y=8(5)+1
y=41 and then you have your answer
If this answer was particularly helpful, please feel free to give it brainliest!! I would greatly appreciate it.
Answer:
(x, y) = (5, 41)
Step-by-step explanation:
y = 8x + 1
y = 3x + 26
Substituting the value of y (first equation) into the second equation, we get:
8x + 1 = 3x + 26
5x = 25
x = 5.
So, to get y, all we have to do is to substitute the value of x into the second equation.
y = 3 * 5 + 26
y = 15 + 26
y = 41
