Answer:
The equation is y = 4x + 5
Step-by-step explanation:
To find the equation to this table, pick two ordered pairs and use the slope formula to find the slope. For this we'll use (4, 21) and (8, 37).
m(slope) = (y2 - y1)/(x2 - x1)
m = (37 - 21)(8 - 4)
m = 16/4
m = 4
Now we can use that slope along with any point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 21 = 4(x - 4)
y - 21 = 4x - 16
y = 4x + 5
Answer:
$3846.87
Step-by-step explanation:
Assuming the interest is compounded annually, the value in 3 years is ...
FV = P(1 +r)^t
FV = $3500(1.032^3) ≈ $3846.87
Sarah's account will be worth about $3846.87.

Answer:
25, 55, 100
Step-by-step explanation:
Let's call the smallest angle x, therefore the other two angles would be x + 30 and 4x. Since the sum of angles in a triangle is 180° we can write:
x + x + 30 + 4x = 180
6x + 30 = 180
6x = 150
x = 25°
x + 30 = 25 + 30 = 55°
4x = 25 * 4 = 100°
