Full Question:
<em>Tony rounded each of the numbers 1,143 and 1,149 to the nearest hundred. Which choice correctly compares the rounded numbers? </em>
<em></em>
Answer:
Step-by-step explanation:
Given
1,143 and 1,149
Required
Which of the option is correct
We start by approximating both numbers to nearest digit
<em>1,143; when approximated to nearest hundred is 1,100</em>
<em>1,149; when approximated to nearest hundred is also 1,100</em>
Hence;
1,143 ≅ 1,100
1,149 ≅ 1,100
Comparing both results, we have that
From the list of given options, option C is correct;
Answer: y=-5x-8
Step-by-step explanation:
Answer: y = -2x + 1 or y +2x - 1 = 0
Step-by-step explanation
Recall, equation of a line passing through two coordinates is
y - y₁ = y₂ - y₁ ( x - x₁ )
₋₋₋₋₋₋₋₋ x
x₂ - x₁
note , (x₁ = -3), (x₂ = 1), (y₁ = 7), (y₂ = -1)
Now substitute for those values in the above equation
y - (7) = -1 - 7
------ X ( x - (-3)
1 - (-3)
y - 7 = -8/4 X ( x + 3 )
y - 7 = -2(x + 3 )
y - 7 = -2x - 6
The equation now
y = -2x -6 + 7
y = -2x + 1 or
y + 2x - 1 = 0.
