Simone invests 1200 into two savings accounts. One account earns 4% annual interest and the other earns 5.9% annual interest. At
Allisa [31]

Answer: He invested $350 at 4% and $850 at 5.9%

Step-by-step explanation:

Let x represent the amount which he invested in the account earning 4% interest.

Let y represent the amount which he invested in the account earning 5.9% interest.

Simone invests 1200 into two savings accounts. One account earns 4% annual interest and the other earns 5.9% annual interest. This means that

x + y = 1200

The formula for determining simple interest is expressed as

I = PRT/100

Considering the account earning 4% interest,

P = $x

T = 1 year

R = 4℅

I = (x × 4 × 1)/100 = 0.04x

Considering the account earning 5.9% interest,

P = $y

T = 1 year

R = 5.9℅

I = (y × 5.9 × 1)/100 = 0.059y

At the end of 1 year, Simon earned 64.15 in interest. it means that

0.04x + 0.059y = 64.15 - - - - - - - - -1

Substituting x = 1200 - y into equation 1, it becomes

0.04(1200 - y) + 0.059y = 64.15

48 - 0.04y + 0.059y = 64.15

- 0.04y + 0.059y = 64.15 - 48

0.019y = 16.15

y = 16.15/0.019

y = 850

x = 1200 - y = 1200 - 850

x = 350

What is the rate of change between (-8,- 8) and (0,8)
iren [92.7K]

{ \qquad\qquad\huge\underline{{\sf Answer}}}

We need to find thr rate of change (slope) of the line joining these two points ~

\qquad \sf  \dashrightarrow \: m =   \dfrac{rise}{run}

\qquad \sf  \dashrightarrow \: m =  \cfrac{8 - ( - 8)}{0 - ( - 8)}

\qquad \sf  \dashrightarrow \: m =  \cfrac{8  +  8}{0  + 8}

\qquad \sf  \dashrightarrow \: m =  \cfrac{16}{8}

\qquad \sf  \dashrightarrow \: m = 2

Slope of the line (m) joining the two points is 2 ~

Select the locations on the number line to plot the points 9/2 and −7/2 .
myrzilka [38]
To plot these points on the number line, you should label the long lines on the number line as such starting from the left (-5-already there, -4,-3,-2,-1,0,1,2,3,4,5-already there).

Now take each number and convert the improper fraction into a mixed number. 9/2 = 4 1/2 and -7/2 = -3 1/2.

4 1/2 would plotted on the line exactly in between the 4 and 5.

-3 1/2 would be plotted on the line exactly halfway between -3 and -4.

You will draw a dot to show each of these positions on a number line.
