Answer:
-1
Step-by-step explanation:
you can look at the graph or the equation. input= x value output=y value
y=1/2x-1 is the equation
It says when x is zero what is y so put in 0 for x
y=1/2(0)-1
y=-1
Answer:
2
Step-by-step explanation:
6 quarters is 1.50
Now you have 1.02
You have a least 2 pennies,
5 times 2 is $1.00
So that leaves 2¢ left over for the pennies
Answer:
The answer to your question is Ф = 45°
Step-by-step explanation:
Data
A (1, 4)
B (-1, 2)
Process
1.- Find the slope of the line
formula
m =
Substitution
m =
Slope definition, is the steepness of a line and also is the tangent of the angle of the line.
tangent Ф = slope
tangent Ф = 1
Ф = tangent⁻¹ 1
Ф = 45°
All you do is multiply across. For example...
1/3 x 2/5
Multiply the numerators and denominators.
(1 x 2) / (3 x 5)
= 2/15
If you need to, you can simplify but in this case you don't have to.
I hope this helps love! :)
Answer:
20789
Step-by-step explanation:
The equation of exponential growth is y=A(1+r)^t
A=10,000
r (rate)=0.05 (5% as a decimal)
t (time)=15 (2035-2020=15)
y=10,000(1+0.05)^15
y=20789.2817
you can't have part of a person, so y=20789
