Answer:
150
Step-by-step explanation:
Since EC is 180,
180-30=150
A) This one has no solutions because the answer of the equation is 0=-1 which isn't true.
b) 6t-3=3t+6 ==> 3t=9 ==> t=3 This means that this has one solution.
c) 6 (2m-3)-3m=2m-18+m ==> 12m-18=2m-18+m ==> 9m=0 ==> m=0 so this one has no solutions.
d) 10+3y-2=4y-y+8 ==> 8+3y=3y+8 ==> 0=0 ==> Infinitely many solutions.

Undefined slope is rise/0
run is equal to 0
that means it doesn't go left or right
means it is vertcal
means it is x=somethig
(x,y)
(-6,4)
x=-6 is the equation
oh, forgot about standard form
standard form is
ax+by=c
so
x+0y=-6 would be the equation in standard form
1) we find the slope of this line:
Given two points, (x₁,y₁) and (x₂,y₂) the slope of the line passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
In this case, we have the points (1,4) and (5,8) and the slope will be:
m=(8-4)/(5-1)=4/4=1
2)Point-slope form of a line:
We need a point (x₀,y₀) and the slope (m);
y-y₀=m(x-x₀)
we can chooso either point of this line (1,4) or (5,8) the end result will be the same.
For example, we choose the point (1,4);
y-y₀=m(x-x₀)
y-4=1(x-1) (point-slope form y-y₀=m(x-x₀))
y=x-1+4
y=x+3 (slope-intercept form y=mx+b)
-x+y=3 (standard form Ax+By=C)
if we choose the point (5,8)
y-8=1(x-5) (point-slope form)
y=x-5+8
y=x+3
-x+y=3
Therefore:
Answer: D. -x+y=3
Answer:
$535
Step-by-step explanation: $681 + 2,150 = 2831 $2831- 691 = 2,140 $2,140/4 = 535 which means they need to sell 535 candy more.
