1) -3x -3 -7x = 17
• start by grouping so add -3x and -7x which gives you -10x
• 10x -3 (+3) = 17 +3 = 20 add 3 on both sides)
• 10x (/10) = 20/ 10 = 2
1) x = 2

2) 10x -6 (+6) = 24 + 6 = 30
• 10x (/10) = 30/ 10 = 3
2) x = 3

3) -4 (+4) -5x = -39 +4 = -35
• -5x (/-5) = -35/ -5 = 7
3) x = 7

4) 3x - 5 > 10
this one i don’t understand, is there a typo maybe ?

5) -5x + x + 16 = -3 you can put a 1 to hold the place of x to make it 1x
• (-5x + 1x) + 16 = -3
• -4x + 16 (-16) = -3 -16 = -19
• -4x (/-4) = -19/ -4 = 4.75 or 4 3/4
5) x = 4.75

Cindy is buying a new car and wants to learn how the value of her car will change over time. Insurance actuaries predict the fut
lawyer [7]

Answer:

C=10000(0.852)^t

Step-by-step explanation:

Let the exponential function be,

C=a(b)^t

Here, C = cost of the car

t = Duration or period in years

From the given table,

Two points representing cost of the car and time are (10000, 0) and (8520, 1),

For (10000, 0),

10000=a(b)^0

a = 10000

For (8520, 1)

8520 = 10000(b)^1

b=\frac{8520}{10000}

b = 0.8520

Therefore, exponential equation will be,

C=10000(0.852)^t

An engineer stands 30 ft. from a building and notes a 55 degree angle of elevation to the top of the building. How high is the b
alexdok [17]
<h3>Answer:  42.8 feet</h3>

Work Shown:

h = height of the building

h is opposite the reference angle (55)

the adjacent side is 30 feet

tan(angle) = opposite/adjacent

tan(55) = h/30

h = 30*tan(55)

h = 42.84444 which is approximate

h = 42.8 feet
