Step-by-step explanation:
6. -18x = 6+ 2= 8
x = 8/-18 = -4/9
7. 20x= -2+4 = 2
20x=2 x= 1/10
8. 8x - 4 = -2
8x= -2+4 = 2
x= 2/8= 1/4
9. -6x-8= -2
-6x= -2+ 8 =6
x= -1
10. -x-3 = -10
-x= -10+3= -7
x=7

Factorise:x^2 + 7x + 10 =0
Answer:
x = − 5, − 2
Step-by-step explanation:
x² + 7x + 10 = 0
x² + 5x + 2x + 10 = 0
x(x + 5) + 2 (x + 5) = 0
(x + 5)(x + 2) = 0
x = − 5, − 2

Determine the constant rate of change for each table.
1. Age (yr) Height (in.)
9514 1404 393
Answer:
2 3/4Step-by-step explanation:
The rate of change in each case can be found by dividing right-column differences by left-column differences.
Table 1
(56 -54)/(10 -9) = 2/1 = 2 . . . the constant rate of change
__
Table 2
(3 -0)/(4 -0) = 3/4 . . . the constant rate of change
_____
Additional comment
Often, in math problems of this sort, you fill in a blank with a number. Above, we have computed those numbers. In real life, it is useful to consider the units that go with that number. The units are divided in the same way the numerical values are.
Table 1: 2 in/yr
Table 2: 3/4 °C/h
Given the Following function; g(t) = 450 (0.34)t , what would the Domain and Range be for the Function?
a
Domain is \large -\infty
b
Domain is \large 450\le x<\infty, Range is \large -\infty
c
Domain is \large 0
d
Domain is 0, Range is 450
Answer:
Given the formula for a function, determine the domain and range.
Exclude from the domain any input values that result in division by zero.
Exclude from the domain any input values that have nonreal (or undefined) number outputs.
Use the valid input values to determine the range of the output values.

Solve 5 – b = 2t for t.
Answer:
[tex] \rm t = \dfrac{5 - b}{2} [/tex]
Step-by-step explanation:
Solve for t:
[tex] \longrightarrow [/tex] 5 - b = 2t
5 - b = 2t is equivalent to 2t = 5 - b:
[tex] \longrightarrow [/tex] 2t = 5 - b
Divide both sides by 2:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{2t}{2} = \dfrac{5 - b}{2} [/tex]
[tex] \sf \dfrac{2}{2} [/tex] = 1:
[tex] \longrightarrow [/tex] [tex] \sf t = \dfrac{5 - b}{2} [/tex]

A brand new car costs $18,000, this price depreciates at 25% every year, how much would the car be after 12 years? 20 years?
Answer:
C(12)=$570.18
C(20)=$57.08
Step-by-step explanation:
Exponential Decay Function
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The depreciation of goods is often modeled as an exponential function. The new car costs $18,000 and its price depreciates at r=25%= 0.25 every year.
The depreciation model is:
[tex]C(t)=18,000\cdot(1-0.25)^t[/tex]
Operating:
[tex]C(t)=18,000\cdot 0.75^t[/tex]
At t=12 years, the price will be:
[tex]C(12)=18,000\cdot 0.75^{12}[/tex]
C(12)=$570.18
At t=20 years, the price will be:
[tex]C(20)=18,000\cdot 0.75^{20}[/tex]
C(20)=$57.08
