Answer:
b = 3/4
Step-by-step explanation:
Using point slope: y - y1 = m(x - x1).
Substitute your given slope, given point, and subsitute 0 in for x and solve for y since the y intercept is the y value when x = 0.
0.2 = 1/5, so 1/5 * 1/4 = 1/20
Therefore: y - 4/5 = 1/4(0 - 0.2) → y - 4/5 = -1/20 → y = 4/5 - 1/20 → 15/20 → <em>3/4</em>
3/5 is the greatest because when you change 3/5 to percantage, it will be 60%.
Let x be the first of the four consecutive numbers.
Then x+1 is the second,
and x+2 is the third,
and x+3 is the fourth.
If their sum is 810, then
x + x+1 + x+2 + x+3 = 810
If you solve that equation for x, you'll have the answer to your question.
Answer: The side length of the pet shop sign=5/4 inches
Step-by-step explanation:
Given: Candy draws a square design with a side length of x inches for the window at the pet shop.
She takes the design to the printer and asks for a sign that has an area of
square inches.
Let y(x) =
differentiating both sides w.r.t x we get
y'(x)=32x-40
to find critical point x ,Put y'(x)=0 then
⇒32x-40=0
⇒x=5/4
Therefore the side length of the pet shop sign=5/4 inches.
This can be translated in two ways.

or

Either way, the only way that this could be equal to 0 is if x = 0.
Therefore the solution is x = 0.
