Answer:

Its position is labeled as -5

Step-by-step explanation:

For elevator 1.

Its position after moving 10 ft up is;

p1 = r + 10

r = reference position.

given that p1 = +10

+10 = r + 10

r = 10 - 10 = 0

The reference position (ground floor) is zero

Since the Elevator 2 moves downward from the reference position (ground floor), it moves in the negative direction.

Its position can be written as;

p2 = r - 5 = 0 - 5 (since r = 0)

p2 = -5

Its position is labeled as -5

Steven's savings account switches from compounding interest annually to quarterly. His account earns 3% interest yearly. Steven

V125BC [204]

Answer:

$0.95 more.

Step-by-step explanation:

The principal of $500, when invested at APR of 3% for 5 years compounded annually will become

$S_1 = 500(1 + \frac{3}{100})^{5} = 579.64$ dollars.

Again, the principal of $500, when invested at APR of 3% for 5 years compounded quarterly will become

$S_2 = 500(1 + \frac{3}{100 \times 4})^{5 \times 4} = 580.59$ dollars.

Therefore, Steven will have $(580.59 - 579.64) = $0.95 more money in his account due to switching from annually to quarterly compounding. (Answer)

How do I solve 2m + n = 2 and 3m - 2n = 3 using substitution?

Leona [35]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Solve 2m + n = 2 and 3m - 2n = 3 using substitution.

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

We can use the substitution method to solve linear equations of this form. Let's solve for m & n.

$\left. \begin{array} { l } { 2 m + n = 2 } \\ { 3 m - 2 n = 3 } \end{array} \right.$

To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.

$2m+n=2, \: 3m-2n=3$

Choose one of the equations and solve it for m by isolating m on the left-hand side of the equal sign.

$2m+n=2$

Subtract n from both sides of the equation.

$2m=-n+2$

Divide both sides by 2.

$m=\frac{1}{2}\left(-n+2\right) \\$

Multiply 1/2 times -n+2.

$m=-\frac{1}{2}n+1 \\$

Substitute $-\frac{n}{2}+1\\$ for m in the other equation, 3m-2n=3.

$3\left(-\frac{1}{2}n+1\right)-2n=3 \\$

Multiply 3 times $-\frac{n}{2}+1\\$ .

$-\frac{3}{2}n+3-2n=3 \\$

Add $-\frac{3n}{2}\\$ to -2n.

$-\frac{7}{2}n+3=3 \\$

Subtract 3 from both sides of the equation.

$-\frac{7}{2}n=0 \\$

Divide both sides of the equation by $-\frac{7}{2}\\$ , which is the same as multiplying both sides by the reciprocal of the fraction.

$\large \underline{\underline{ \bf \: n=0 }}$

Substitute 0 for n in $m=-\frac{1}{2}n+1\\$ . Because the resulting equation contains only one variable, you can solve for m directly.

$\large \underline{ \underline{\bf \: m=1 }}$

The system is now solved.

$\huge \boxed{ \boxed{ \bf \: m=1, \: n=0 }}$
