Hey there! :)
y = 3/4x - 2
To find the slope and y-intercept, simply use slope-intercept form to understand this.
Slope-intercept form is : y = mx + b ; where m = slope, b = y-intercept.
Therefore, you must ask yourself : which value is in the "m" spot and which value is in the "b" spot in our given equation?
Using this logic, we can come to the conclusion that :
Slope = 3/4 & Y-intercept = -2
~Hope I helped! :)
Answer: 5931.8m^2
Explanation:
Explanation:
85.9 x 48 + 3.14 x 24^2
= 4123.2 + 1808.64
= 5931.8m^2
Answer:
x = 3
Step-by-step explanation:
5.8x - 1.4 = 16 {add 1.4 to both sides}
5.8x = 16 + 1.4
5.8x = 17.4 {Divide both sides by 5.8}
x = 17.4/5.8
x = 3
For the answer to the question above,
since the only variable used to determine earnings is the number of doors knocked, you can eliminate options 1 and 3 as they are based on the number of books sold, which is not a part of the equation.
That leaves the only options being the increase of $20 or $50 for each door knocked. As the x value we multiply by 20, the correct answer is #2, her earnings will increase by $20 for each door knocked.
You can also check this by plugging in values:
Assume 10 doors are knocked:
E(10) = 20(10)-50 = 200-50 = 150
Assume 11 doors (1 more door) is knocked:
E(11) = 20(11)-50 = 220-50 = 170
<span>The increase from 1 door is $20. the answer is B</span>
