Answer:

Step-by-step explanation:
The line that passes through the two points (6, -23) and (11, r) has a slope of 4.
We want to determine the missing value of r.
We can use the slope formula:

Let (6, -23) be (x₁, y₁) and let (11, r) be (x₂, y₂). The final answer should be 4. Therefore:

Simplify and evaluate:

Multiply both sides by 5:

Therefore:

Answer:
Tn = 17-6n
Step-by-step explanation:
d = 5-11 = -6
Tn = a + (n-1)d = 11 + (n-1)×-6
= 11 -6n +6 = 17-6n
It’s the 3rd one I believe
Answer:
ok Betty what are they my dude
Answer:
x = -2
∠A = 35
Step-by-step explanation:
x + 37 + x + 57 = 90
reduce:
2x = -4
x = -2
∠A = 37-2 = 35
