Answer:
It should be 4 or (0,4)
Step-by-step explanation:
The y-intercept is just where one of the lines of the graph crosses the y-axis, which in the picture shows it crosses at (0,4)
Answer:
The last one at the right
Step-by-step explanation:
It is a function because not of the x axis numbers are repeated.
Answer:
<h2>The missing value is 2. The coordinate will be (-5, 2)</h2>
Step-by-step explanation:
The question is not properly written. Find the correct question below.
If x – 5y = -15
. Complete the missing value in the solution to the equation (-5, ____)
Let the coordinate of the variables be (x, y). Comparing the coordinates (x, y) with the given coordinate (-5, __), we will discover that x = -5. To get the y coordinate, we will substitute x = -5 into the given expression as shown;
If x – 5y = -15
-5 - 5y = -15
Adding 5 both sides
-5-5y+5 = -15+5
-5y = -10
Dividing both sides by -5;
-5y/-5 = -10/-5
y = 2
<u>Hence the missing value in the solution of the equation is 2</u>. The coordinate will be (-5, 2)
Discriminant = square root (b^2 -4*a*c)
square root (64 -4*1*12) =
square root (16) =
4
Therefore it has 2 rational soltions
