Answer:
y = - 
x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = 
= -
The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = - x - 1 ← equation of line
Answer:
17.5 hours
Step-by-step explanation:
5x-5 over 4 days and the plan to travel 4.5 hours each day. WE have to find how many hours will they drive each day. Now, to find the total time pu x to 4.5 in the above expression. 5(4.5)-5
= 22 * 5-5 = 17. 5 hours over the four days of traveling
Answer:
9
Step-by-step explanation:
How I got my answer:
a+ bc turns into 7 + 4 x 1/2
First, you do 4 x 1/2 which equals 2 ( 4/1 x 1/2 = 2)
Then, you add 7 and 2

Answer:
12 years
Step-by-step explanation:
From the formula;
A = P(1 + r)^n
A = Amount = $2733.19
P = Principal = $2150
r = rate = 2%
n = time in years = ???
2733.19 = 2150(1 + 0.02)^n
2733.19/2150 = (1 + 0.02)^n
1.27 = (1.02)^n
Taking logarithm of both sides
log 1.27 = n log 1.02
n= log 1.27/log 1.02
n= 0.1038/0.0086
n = 12 years
