3y=6+x
y=(6+x)/3
y=2+x/3
y=mx+b
y=x/3+b
so m(slope) is 1/3
use the point (3, 5), sub this for x and y
5=3/3+b
5-1=b
b=4
therefore, y=x/3+4
or y=(1/3)x+4 (you can write it like this as well)
The correct option is D. In fact, you can evaluate this function at every possible input x.
All this function does is:
- Take a number x
- Add 6
- If the result is negative switch the sign, otherwise keep it as it is
As you can see, you can perform these operations regardless of the input x.
Answer:
The student ticket is 200 and the adults is 550
Step-by-step explanation:
So the set up is :
750 = x + y
5300 = 8x + 4.5 y
x will be adults and y will be students
Assuming you don't have calculator then you want to be able to eliminate either x or y from this system. The easiest is X cause its a whole number.
So multiply all the numbers from the first equation by 8 which gives
6000 = 8x + 8 y
5300 = 8x + 4.5 y
Then subtract the numbers (6000-5300 and 8x-8x and 8y-4.5y)
which gives :
700 = 3.5y
Solve for y = 200
and plug 200 back into any equation to solve for X
750 = x + 200
x = 550
Answer:
<h2><em><u>
1. x = 36 is the answer.</u></em></h2><h2><em><u>
2. x = 123 is the answer.</u></em></h2>
Step-by-step explanation:
1. 4x = angle 4
x = angle 1
Angle 1 + angle 4 = 180
4x + x = 180
5x = 180
<h2><em><u>
x = 36.</u></em></h2>
<em><u></u></em>
2. 55 = angle 2
angle 1 = 68
angle 3 = 55 + 68 = 123 = 180 - 123 = 57
Angle 4 = 57
<h2>180 - 57 = 123</h2><h2><em><u>
x = 123</u></em></h2><h2><em><u>
</u></em></h2>
