we need the graph/ lines,

but just remember

wherever 2 lines intersect, that is a solution

if they are paralell, no solutions

if they cross, 1 solution

if they are the same line/ the lines are on top of each other exactly, infinite solutions

The drama club spent $35 on decorations and $8.50 per person on food for a cast party. The total cost of the food

jenyasd209 [6]

Answer:

Option C) 27 people

Step-by-step explanation:

Let

x ----> the number of people

we know that

The cost of decorations ($35) plus the number of people (x) multiplied by the cost per person on food ($8.50) must be equal to $264.50

The linear equation that represent this situation is

$35+8.50x=264.50$

solve for x

Subtract 35 both sides

$8.50x=264.50-35$

$8.50x=229.50$

Divide by 8.50 both sides

$x=229.50/8.50$

$x=27\ people$

X/4 = 3/8 solve for x

Andrei [34K]

The ratio of 4 to 8 simplifies to 1:2. X will therefore be 3/2, as 3/2:3 simplifies to 1/2 (3 = 6/2).

Gg easy

point slope:
for opint (x1,y1) and slope m
y-y1=m(x-x1)

so example
(1,2) and slope 3
y-2=3(x-1)

slope intercept
y=mx+b
m=slope
b=y intercept
if slope is 2 and y intercept is 3
y=2x+3

standard form
Ax+By=C
easies of all, just put randome numbers

2x+3y=4
A=2
B=3
C=4
