Answer:
t= -1
Step-by-step explanation:
where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
cross multiply:
1(t -6)= 7(-1)
t -6= -7
+6 on both sides:
t= -7 +6
t= -1
Answer:
95
Step-by-step explanation:
Use the mean formula: mean = sum of elements / number of elements
Plug in the mean and number of elements, then solve for the sum of the numbers:
mean = sum of elements / number of elements
19 = sum of elements / 5
95 = sum of elements
So, the sum of the numbers is 95.

Answer:
12.6
Step-by-step explanation:
The question requires you to estimate the product of 0.12 * 105
12/100 * 105 ----multiply 12 and 105
12 * 105 = 1260
Divide the answer by 100
1260/100 = 12.6
Answer:
y will increase by 8
Step-by-step explanation:
y = 8x+2
We increase x by 1
Replace x with x+1
y = 8(x+1) +2
y = 8x+8+2
y = 8x+2 +8
y will increase by 8
