Y=x<br> y=-6x–14<br><br> (substitution method)

olga_2 [115]

Answer:

The solution is the point (-2,-2)

Step-by-step explanation:

we have

$y=x$ ----> equation A

$y=-6x-14$ ----> equation B

Solve the system by substitution

substitute equation A in equation B

$x=-6x-14$

Solve for x

$6x+x=-14\\7x=-14\\x=-2$

Find the value of y

substitute the value of x in the equation A

$y=x$

$y=-2$

therefore

The solution is the point (-2,-2)

A right triangle has a hypotenuse of 10 mi. and a leg of 6 mi., what is the length of the other leg?

slava [35]

Answer:

8mi

Step-by-step explanation:

Using Pythagoras theorem

Hypotenuse square = opposite square + adjacent square.

Let the other leg be x

10 square = 6 square + x square

100 = 36 + x square

Collect like terms

X square = 100 -36

X square = 64

Find square root of both sides

X = square root of 64

X =8mi

Dale is 35 years old and planning to retire at age 65. He will invest an average of $155 each month with an average annual retur

weeeeeb [17]

Since he is investing the same amount monthly, we have to apply annuity formula. And it is planned for the future. So that, we'll apply future value annuity formula. The formula is $FV=A[ \frac{(1+ \frac{r}{s})^{Ns} -1 }{r} ]$ , where A is the monthly payment, r is the percentage rate, s is 12 (monthly compound) and N is the time, which is 30. Plugging the numbers into the formula, we write that $FV=155[ \frac{(1+ \frac{0.037}{12} )^{12*30} - 1 }{0.037} ]$ = $8485.450857
