Answer:
y = 3 - 4x
To find the y intercept let x = 0
y = 3 - 4(0)
y = 3 or ( 0 ,3)
Hope this helps.
Width of the rectangle is 10 m
<u>Step-by-step explanation:</u>
Step 1:
Let the width of the rectangle be x. Then length of the rectangle will be 8 + 6x. Perimeter = 156m
Perimeter of a rectangle = 2 (length + width)
⇒ 156 = 2 (8 + 6x + x)
⇒ 156 = 16 + 14x
⇒ 140 = 14x
∴ x = 140/14 = 10 m
⇒ Width of the rectangle is 10 m
Answer:
C. 2/3
Step-by-step explanation:
12 female / 18 male
Dividing by 6 we get:
2 female / 3 male
or 2/3
The functions that model R for men and women are missing.
Nevertheless, I searched for them and here they are:
For women, R = 143 - 0.65a
For men, R = 165 - 0.75a
You are asked for the age of a man whose desirable R is 135, so you must use the equation for men, R = 165 - 0.75a, replace 135 for R and solve for a.
=> 135 = 165 - 0.75a
=> 0.75 a = 165 - 135
=> 0.75 a = 30
=> a = 30 / 0.75
=> a = 40.
Answer: option b. 40 years old.
