Answer:
![25x+12y+4 \leq 130](https://tex.z-dn.net/?f=25x%2B12y%2B4%20%5Cleq%20130)
Step-by-step explanation:
Here, x represents the number of tickets and y represents the number of T-shirts.
As per the statement:
Each ticket costs $25, and souvenir T-shirts are $12 each
⇒Total cost of ticket = 25x and Total cost for T-shirt = 12y
It is also given that there is a $4 service fee for the entire purchase.
![25x+12y+4](https://tex.z-dn.net/?f=25x%2B12y%2B4)
Since, she has $130
⇒![25x+12y+4 \leq 130](https://tex.z-dn.net/?f=25x%2B12y%2B4%20%5Cleq%20130)
Therefore, an inequality could you use to answer the problem is, ![25x+12y+4 \leq 130](https://tex.z-dn.net/?f=25x%2B12y%2B4%20%5Cleq%20130)
Answer:
x= -10
Step-by-step explanation:
Subtract 8x from 4x ( -4x )
-4x-34=6
Add 34 to 6 ( 40 )
-4x=40
Divide by -4 ( -10 )
x= -10
Answer:
m = 2/3
b = -3
Step-by-step explanation:
Rearrange the equation to slope-intercept form (y = mx + b).
x and y are points on the graph.
m is the slope.
b is the y-intercept.
Isolate "y". This means separating it from the other numbers.
-2x +3y = -9
-2x + 2x +3y = -9 + 2x Add 2x to both sides
3y = 2x - 9
3y/3 = 2x/3 - 9/3 Divide both sides by 3
y = 2x/3 - 9/3 Simplify
y = (2/3)x - 3
Think about which numbers and "m" and "b" now that the equation is in y = mx + b. Include the plus and minus signs.
m = 2/3
b = -3
You first wanna find <BAD, because if AB is perpendicular to AC, then it has to form a 90 degree angle. So 90-56=34 degrees. So now you have a 34 & 63 degrees in the ABD triangle. In a triangle, all angles add up to equal 180 degrees. So 34+63+x=180...and x=83. So <ADB= 83 degrees. Now you want to find angle ADC...which you can just subtract 83 from 180 (because <ADB & <ADC forms 180 degree angle). You will then get 97 as angle ADC. So, the same thing as before, add up 56+97+x=180, because all angles (in the triangle ADC) add up to be 180 degrees. X will then equal 27 degrees. Angle ACB= 27 degrees.
