We know that the interest decreased by 29.3%, therefore
what was left now is simply just 70.7% of the original, therefore we divide
this by 0.707
rate = 7.7% / 0.707
rate = 10.89%
<span>So the rate was 10.89% 10 years ago</span>
Answer:
The answer is B.
Step-by-step explanation:
because the starting point is 3 and by the use of the slope triangle, you end with 4 for the slope.
Answer:
<u>The equations system has multiple solutions for x, y.</u>
Step-by-step explanation:
Let's solve for x and y this equations system:
We can observe that the second equation is a simplification of the first (divided by 2) and therefore, the system has multiple solutions for x and this way:
x y
-27/5 -5
-21/5 -4
-3 -3
-9/5 -2
-3/5 -1
3/5 0
9/5 1
3 2
21/5 3
27/5 4
33/5 5
<h2>
Answer: y = ⁶/₇ ( x - 7 )</h2>
Step-by-step explanation:
The slope of tghe line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (- 6 -0) ÷ ( 0 - 7)
= ⁶/₇
We can now use the point-slope form to write the equation for this line:
y - y₁ = m(x - x₁) where (x₁ , y₁) = (7 , 0)
y = ⁶/₇ ( x - 7 )
