Erin invests $7000 in stocks and bonds. The bonds earn 5% annual interest and the stocks earn 8% interest. If she earns $404 in

Marina CMI [18]

Answer:

$\large \boxed{\$5200}$

Step-by-step explanation:

Let b = the amount invested in bonds

Then 7000 -b = the amount invested in stocks

0.05b = interest from bonds

0.08(7000 - b) = interest from stocks

$\begin{array}{rcll}0.05b +0.08(7000 - b) & = & 404 &\\0.05b + 560 - 0.08b&=&404&\text{Distributed the 0.08}\\-0.03b + 560 & = & 404 & \text{Simplified}\\-0.03b & = & -156 & \text{Subtracted 560 from each side}\\\\b & = & \dfrac{-156}{-0.03} & \text{Divided each side by -0.03}\\\\b & = &\mathbf{5200}\\\\\end{array}\\\text{Erin invests $\large \boxed{\mathbf{\$5200}}$ in bonds}$

Line passes through the point (2,10) and has a y-intercept of 4. what is the equation of the line?

ZanzabumX [31]

Answer:

y = 3x + 4

Step-by-step explanation:

y = mx + b

b = y-intercept so:

b = 4

Since 4 is the y-intercept that means (0, 4).

To find slope:

m=(y2-y1)/(x2-x1)

m=(4 - 10)/(0 - 2)

m= (-6)/(-2)

m= 3

Slope-intercept:

y - y1 = m(x - x1)

y - 10 = 3(x - 2)

y - 10 = 3x - 6

y = 3x + 4
