Your answer would be y = (-1/4)x - 1
Seeing as they give us the slope, all we have to is find the y intercept of the line. We can do this by substituting in the coordinates (8, -3), and using the 8 as x and the -3 as y.
This gives us:
-3 = (-1/4 × 8) + c
-3 = -8/4 + c
-3 = -2 + c
c = -1
So therefore the final answer is y = (-1/4)x - 1
I hope this helps!
Answer:
Step-by-step explanation:
4 (x + 3) = 2x + 8 <----"four times the sum of a number and three is equal to eight more than twice the number."
Second, we want to solve the equation:
4 (x + 3) = 2x + 8
4x + 12 = 2x + 8
2x + 12 = 8 <-------subtract 2x from both sides of the equation.
2x = -4 <-------subtract -12 from both sides
x = -2 <-------divide both sides by 2 which leaves a negative answer
Third, we want to check the answer by substituting the value of -2 for x in the original equation.
4 (x + 3) = 2x + 8
4 (-2 +3) = 2(-2) + 8
-8 + 12 = -4 + 8
4 = 4
4 (x + 3) = 2x + 8 <----"four times the sum of a number and three is equal to eight more than twice the number."

Answer:
4
Step-by-step explanation:
circumference = 2πr
or, 20 = 2π r
or, π r = 10
or, r= 10/π
72 ° = 2π/5
length of arc = r∅ = 10/π × 2π/5
= 4
Answer:
the answer is: 3/4
Step-by-step explanation:
because, 1/4 + 1/4 + 1/4 = 3/4
