Answer:
B) (8, 0) and (-4,0)
Step-by-step explanation:
x-intercept when y = 0
so
x^2 - 4x - 32 = 0
Factors
(x - 8)(x + 4 ) = 0
x - 8 = 0; x = 8
x + 4 = 0; x = -4
(8, 0) and (-4,0)
Answer:
All of the whole numbers
Step-by-step explanation:
absolute value" means to remove any negative sign in front of a number, and to think of all numbers as positive
Answer:
33.33%
Step-by-step explanation:
We need to calculate the <u>unit selling price and cost of each cosmetics.</u>
If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then for 1 cosmetics, we will say;
x = 1 cosmetic
since 360 = 12 cosmetic
cross multiply
12x = 360
x = 360/12
x = 30
Hence the unit cost price of the cosmetics will be Rs. 30
Similarly, if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40 (a pair is 2 cosmetics)
Selling price per unit = Rs. 40
Cost price per unit = Rs. 30
percent gain = SP-CP/CP * 100%
percent gain = 40-30/30 * 100
percent gain = 10/30 * 100
percent gain = 100/3
percent gain = 33.33%
Hence the percentage gain is 33.33%
Answer:
It would be 125m^2
Step-by-step explanation:
17*10=170
170/2=85
8*10=80
80/2=40
85+40=125
If x < - 2 and x ∈ { - 5, - 2.6, - 2, - 0.8, 1, 1.5 }
- 5 < - 2 and - 2.6 < - 2
The solution set is:
A ) { - 5 , - 2.6 }
