Answer:
x=87 degrees
Step-by-step explanation:
Answer:
We verify: a < b + c; b < a + c; c < a + b;
Only a = 9, b = 12, c = 7 verify the conditions: 9 < 19; 12 < 16; 7 < 21;
The correct answer is D.
Step-by-step explanation:
Answer:
The distance is 
or 
.
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula 
Insert (0,7) and (4,5)
= 
Answer:
Step-by-step explanation:
Let x represent the number of miles after which the cost of both options will be the same.
You have two payment options. Option A is to buy a monthly pass for $30 and pay $0.80 per ride. This means that the total amount that you would pay for x miles if you use this option is
0.8x + 30
Option B is to pay $2.30 per ride. This means that the total amount that you would pay for x miles if you use this option is
2.3x
An equation to show after how many rides the cost will be the same would be
0.8x + 30 = 2.3x
2.3x - 0.8x = 30
1.5x = 30
The product of 14x25x4 is 1400 but I don't understand why you put use subtraction.
