Answer:
7
Step-by-step explanation:
10.5*2/3= 3.5*2=7
Answer:
a = 0.3 and b = - 1.1
Step-by-step explanation:
(x - 2)² = x² -4x + 4
Hence, x² - 4x + 4 = 3x - 6
x² - 7x + 10 = 0
(x - 5)(x - 2) = 0
∴ x = 5 or 2
f(5) = 25a + 5b = 2 ----- (i)
f(2) = 4a + 2b = -1 ------ (ii)
(i) X 2: 50a + 10b = 4 ----- (iii)
(ii) X 5: 20a + 10a = -5 ---- (iv)
Subtract (iv) from (iii): 30a = 9
a = 0.3
Substitute a into (ii) to obtain b
4(0.3) + 2b = -1
2b = -1 - 1.2 = -2.2
∴ b = -1.1
Answer:$2175
Step-by-step explanation:
set up an equation
15x+675
15(100) +675= 2175
15 is the additional cost per person
675 is the renting fee for the building
100 is the number of people attending
Hope this helps
Answer:
(5√x) / [(3√x)-4]
Step-by-step explanation:
You cannot solve this because 5, 3, and 4 are not factors/multiples of one another
I simplified it though
when the exponent is 1/2, it is the same as taking the square root of something
5x^1/2 is the same as 5√x
3x^1/2 is the same as 3√x
