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
so
The linear equation that represent this situation is
solve for x
Subtract 35 both sides
Divide by 8.50 both sides
Its increasing by 4 so it is 4x
The y intercept(other missing value) is 18
34-4=30
30-4=26
26-4=22
22-4=18
So its 4x+18
Answer:
y = 7
Step-by-step explanation:
0.3y+0.6 = 9.7 - y
0.3y+y = 9.7 -0.6
1.3y = 9.1
y= 7

Step-by-step explanation:
Answer:
Step-by-step explanation:
Solve the quadratic equation by factorizasion
- x² + x - 6 = 0
- x² - 2x + 3x - 6 = 0
- x(x - 2) + 3(x - 2) = 0
- (x + 3)(x - 2) = 0
- x + 3 = 0 or x - 2 = 0
- x = - 3 or x = 2
