Answer: The money has to remain in the account for a specified period of time.
Answer:
27°,63°
Step-by-step explanation:
Let the two angles be a and b.
They are complementary, meaning they add up to 90. Thus:
And we are told their difference is 36. Therefore:
Solve for the system of equations. Add b to both sides in the second equation:
Substitute this into the first:
Combine like terms;
Subtract 36:
Divide by 2:
So, b is 27 degrees.
Use the second equation again:
Now that we know b is 27, substitute:
Add 27 to both sides:
So, a is 63 degrees.
And we're done :)
Answer:
80 is the actual number
Step-by-step explanation:
(28/7)(6)=24
24 x 100=2400
2400/30=80
80 x .3 = 24
(0,16)
<span>y - 4 = -2(x - 6)
y - 4 = -2x + 12
y = -2x + 12 + 4
y = -2x + 16
and the y-intercept is (0,16) which lies on the line of </span><span>y - 4 = -2(x - 6). </span>
Answer:
gradient = 2
line: y = 2x - 4
Step-by-step explanation:
Find the slope from the slope intercept formula
y = mx + b
b is the y intercept
b = -4 and the point is (0,-4)
So far the equation looks like this.
y = mx - 4
Use the other intercept (x intercept) to find m
x = 2
y = 0
0 = m*2 - 4 Add 4 to both sides
4 = 2m Divide by 2
4/2 = m
m = 2
So the gradient or slope is 2
