What is the answer for number 2? Plz help

Hello! So, the sum of the angles of a triangle is 180 degrees. There’s already an angle that is 60 degrees. So, there are 120 degrees left to be found. You set this formula up as 3y = 120. Divide each side by 3 to isolate the y. When you solve that, you should get y = 40.
2y = 80 degrees
y = 40 degrees

9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing

Andre45 [30]

Step-by-step explanation:

Hey there!

The equation, of a st. line that passes through point (5,9) is,

$(y - y1) = m1(y - y1)$

Put the values,

$(y - 9) = m1(x - 5)$

It is 1st equation.

Now, another equation is,

y = 3x-1.........(ii)

Comparing the equation with y = mx+c.

Slope (m2)= 3

As per the parallel lines,

m1=m2=3

Putting,

the value of m1 in equation(i)

(y-9)= 3(x-5)

y-9= 3x - 15

y = 3x - 6.

So, Krista equation is correct.

Hope it helps...

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
