Answer: -5/3
Step-by-step explanation:
Use the slope formula: 
You substitute the numbers in and subtract to get -5/3.
Part A
5x - 5 >= 10 or-3x + 1 > 13
1) This is a disjunction (OR)
5x - 5 >= 10
5x >= 15
x >= 3
or
-3x + 1 > 13
-3x > 12
x < -4
Answer
x <- 4 or x >= 3
Part C:
1) This is a conjunction (And)
5x+ 3 <= 18 and 4 - x < 6
5x <= 15 and - x < 2
x <= 3 and x > -2
Answer
-2 < x <= 3
Answer:
f(x) = 1.50x - 15
Step-by-step explanation:
Given that:
Worth of prepaid charge card = $15
Cost per ride = $1.50
Amount after each ride :
In solpe - intercept form:
Cost per ride = slope = 1.50
Intercept = $15
Amount left after each ride, f(x)
Number of ride, x
f(x) = 1.50x - 15
Answer:
x = 17
<2 = 121
Step-by-step explanation:
We know that angle 1 and angle 3 form a linear pair, which means they add to 180
7x+2 + 3x+8 = 180
Combine like terms
10x+ 10 = 180
Subtract 10 from each side
10x+10-10 = 180-10
10x = 170
Divide by 10
10x/10 =170/10
x = 17
Angle 1 and angle 2 are vertical angles and vertical angles are equal
<1 = <2 = 7x+2 = 7(17) +2 =119+2=121
