Answer:

see attached

Step-by-step explanation:

a) A system of equations has no solutions when the graphs of those equations do not intersect. If the equations are equations of a line, then the lines must be parallel in order for them not to intersect.

Any parallel line will do.

b) There is one solution when the graphs intersect in exactly one point.

Any line that crosses the one shown will do.

c) There are infinite solutions when the graphs describe the same curve.

A line overlapping the one shown is the one you want.

Sveta_85 [38]

$\text {Hello! Let's Solve this equation!}$

$\text {Since there is a negative in the problem this tells us that the answer we get will be a negative.}$

$\text {Here are some tips on dividing/multiplying equations like this.}$

$\text {Multiplying/Dividing a Positive to a Positive will equal a Positive}\\\text {Multiplying/Dividing a Positive to a Negative will equal a Negative}\\\text {Multiply/Dividing a Negative to a Negative will equal a Positive}\\\text {Multiplying/Dividing a Negative to a Positive will equal a Negative}$

$\text {Now Divide!}$

$\text {12/-4=}$

$\fbox {-3}$

$\text {As you can see 4 is a negative number so our result came out as a negative number.}$

$\text {Want to see if your answer is correct? Sure! Do the opposite of Dividing and Multiply!}$

$\text {-3*-4=12}$

$\text {Best of Luck!}$

Rose and Dennis each open a savings account at the same time. Rose invests $2,600 in an account yielding 4.1% simple interest, a

vodka [1.7K]

The formula is
A=p (1+rt)
A future value
P present value
R interest rate
T time in years

Rose investment
A=2,600×(1+0.041×9)
A=3,559.4

Dennis investment
A=2,200×(1+0.057×9)
A=3,328.6

So Rose investment is greater than Dennis investment by
3,559.4−3,328.6=230.8

Hope it helps!
