Answer:
y=(-3/2)x+24
Step-by-step explanation:
a perpendicular line should have the negative reciprocal of the line that it is perpendicular to.
negative reciprocal of 2/3 is -3/2
out line should look something like this
y=(-3/2)x+b
then we use the given point to find b
6=(-3/2)12+b
6=-18+b
b=24
Answer:
(a) A is steeper; 4/5 > 2/5
Step-by-step explanation:
The slope of A is the coefficient of x, so is 4/5. This eliminates choices B and D.
The line in the graph has a rise of 2 units for each run of 5 units, so has a slope of ...
slope = rise/run = 2/5
This eliminates choice C.
The correct description of the relationship is the first one:
Equation A has a steeper slope, because 4/5 is greater than 2/5.
910 is 9.1 × 10^2 in scientific notation
Answer: The slope, 20, represents the miles driven per gallon of gas. The y-intercept is 0, it represents the number of miles driven after 0 gallons.
Explanation:
(100-0)/(5-0)=20
(160-100)/(8-5)=20
(180-160)/(9-8)
When x=0 y=0
Answer:
78.8 %
Step-by-step explanation:
From the question,
Area of the square = L²
A = L²
Where L = Length of the square.
From the diagram,
L = 4 in
Therefore,
A = 4²
A = 16 in².
Also,
Area of the circle (A') = πr²
Where r = radius of the circle.
Given: r = 2 in
Therefore,
A' = 22/7(2²)
A = 12.6 in²
Hence,
The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A
Pr = 12.6/16
Pr = 0.7875
Pr(%) = 78.75
Pr(%) = 78.8 %
