The Answer is A.
To solve the equation for x you need to find a, b and c of the quadratic then apply the quadratic formula resulting in that answer.
An equation has infinitely many solutions if it can be manipulated all the way to an identity (i.e. an equality where the right and left hand side are the same). We have:
A) 
which is impossible
B) 
which is an equality
C) 
which has a unique solution
D) 
which has a unique solution
slope-point form:
we need the slope (m) and a point.
y-y₀=m(x-x₀)
Given two point A(x₁,y₂) and B(x₂,y₂), the slope of the line is :
m=(y₂-y₁) /(x₂-x₁)
Example 3:
we can take two points:
A(12,2)
B(13,7)
m=(7-2) / (13-12)=5/1=5
therefore:
y-2=5(x-12)
y-2=5x-60
y=5x-60+2
y=5x-58
answer: y=5x-58
Example 4:
we can take two points.
A(0,0)
B(3,1)
m=(1-0)/(3-0)=1/3
Therefore:
y-0=1/3(x-0)
y=x/3
answer: y=x/3
Answer:
158.333333
Step-by-step explanation:
do the percent correct divided by the number of questions then multiply it by 100
95/60=1.58333333
1.58333333*100=158.333333
Answer:
so, lauren isn't correct
Step-by-step explanation:
3x + 4 (2x + 5) = 6x + 5x + 5
3x + 8x + 20 = 11x + 5
11x + 20 ≠ 11x + 5
