Answer:
Solving the quadratic equation we get:
Step-by-step explanation:
We need to solve the quadratic equation:
We can solve the quadratic equation of form using quadratic formula:
We need to put values of a , b and c in order to find the solutions of quadratic equations.
In the given equation: we have, a =8, b=37, c=0
Putting values and finding the values for n:
So, solving the quadratic equation we get:
m^2-2mn+n^2 m=-2
(-2)^2-2*-2*4+(4)^2
=>4+16+16
=>36

Answer:
a. -0.89
Step-by-step explanation:
The easiest way to solve this is that 0.03 - 0.92 is also the same thing as -0.92 + 0.03, your answer should be -0.89 which you are adding up 0.03.
Answer:
Step-by-step explanation:
These equations are all written in slope-intercept form, so the question is relatively easy to answer. These rules apply.
- if slopes are different: 1 solution
- if slopes are the same and y-intercepts are different, 0 solutions
- if slopes are the same and y-intercepts are the same, infinitely many
1. y=-6x-2; y=-6x-2 --- infinitely many
2. y=0.5x+5; y=0.5x+1 --- zero
3. y=0.25x-2; y=5x-4 --- one
4. y=2x+3; y=4x-1 --- one
5. y=2x+1.5; y=2x+1.5 --- infinitely many
6. y=-x-3; y=-x+3 --- zero
_____
Slope-intercept form is ...
y = mx +b
m is the slope
b is the y-intercept
