Answer:
Step-by-step explanation:
the graphs of the equation x=3 and y=3 intersect each other at point (3 , 3)
x = 3 is parallel to x-axis and y = 3 is parallel to y- axis
Answer:
You asked to solve questions 3 and 5
<h3>#3</h3>
Since CD = EF,
- 9x - 1 = 41 - 5x
- 9x + 5x = 41 + 2
- 14x = 42
- x = 3
<h3>#5</h3>
MN = NP as their perpendicular bisectors are of same length.
- 9x - 43 = 5x + 33
- 9x - 5x = 33 + 43
- 4x = 76
- x = 19
- mMP = 360 - (mMN + mNP)
- mMP = 360 - (9*19 - 43 + 5*19 + 33)
- mMP = 104
<span>x is the number of tacos needed to make $210
3.25x greater than or equal to $210
x is greater than or equal to 210/3.25
x is greater than or equal to 64.6
The stand needs to sell at least 65 tacos to make a profit.

Answer:
x=3or-1
Step-by-step explanation:
x-3 (5x-6)=3-10x
5x^2-15x-6x+18=3-10x
collect like terms
5x^2+18-3=15x+6x-10x
5x^2+15=11x
5x^2-11x+15=0
factorise
(x-3) (5x+5) =0
...... x=3 or -1
