I don't think that you put parentheses around any numbers because when I solve it with parentheses between numbers I get other numbers like 16 or 17

5. Katie makes and sells scarves. Her monthly profit is given by P(s) = -s2 + 25s - 100, where "s" is the selling price. For wha
Marat540 [252]

Answer: s > 5

Step-by-step explanation:

-s² + 25s - 100 > 0

Coefficient of s² is -1, multiply the equation through by -1.

-1 × (-s² + 25s - 100)

s² — 25s + 100

ax² + bx + c

Then you get the factors x and y that gives x + y = b and xy = c

b = -25 and c = 100, x = -20 and y = -5

-20 × -5 = 100 and -20 + -5 = -25

Then

s² — 20s — 5s + 100 > 0

Factorising,

s (s — 20) — 5(s — 20) > 0

(s — 5)(s — 20) > 0

(s — 5) > 0 and (s — 20) > 0

s>5 and s>20

s > 5

Hope this Helps?

Is (1, 4) a solution to the equation y = 7x?
wolverine [178]

Answer:

No.

Step-by-step explanation:

No because if we substitute the given values into the equation they do not fit:

y = 7x

x = 1 and y = 4:

Left side = 4

right side = 7*1 = 7.

Holland added three decimals that made a sum of 2. One of the decimals was 0.34. What are two other decimals Holland could have
bogdanovich [222]
Using x to represent our missing values and the fact that there are two missing values gives us x + x = 2x. Because it's the sum of these numbers and 0.34, we get the equation 2x + 0.34; now we set it equal to 2, 2x + 0.34 = 2. 

To solve, 1st subtract 0.34 on both sides to get 2x = 1.66. Now divide by 2 on both sides to get x = 0.83. 

So your decimals are 0.34, 0.83, and 0.83
