Answer:

D) y = 2x + 4

Step-by-step explanation:

plug the slope and the x-and-y coordinates into the slope-intercept form of a line to get the y-intercept:

y = mx + b

2 = 2(-1) + b

2 = -2 + b

4 = b

y = 2x + 4

8X +6Y+4<br> Y=-3X+9<br> using substitution what numbers are the variables X and Y

Svetach [21]

Answer:

(5,6)

Step-by-step explanation:

8X +6Y=4

Y=-3X+9

Substitute the second equation into the first. Every place you see y put -3x+9)

8x +6(-3x+9)=4

Distribute

8x-18x +54 = 4

Combine like terms

-10x +54 = 5

Subtract 54 from each side

-10x +54-54=4-54

-10x = -50

Divide by -10

-10x/-10 = -50/-10

x= 5

Now we need to find y

y = -3x+9

y = -3(5) +9

y = -15+9

y= 6

If you invest in a mutual fund that pays annual interest compounded monthly over 5 years, what annual interest rate is needed to

grigory [225]

Answer:

Step-by-step explanation:

This may seem a bit tricky because we are not given enough info really to plug in and solve for the rate. We are told, however, that we are interested in doubling whatever amount we invested. So it is up to us to pick an amount for P, then double it for A(t). Let's use P = 1000 so A(t) = 2000. Filling in then:

$2000=1000(1+\frac{r}{12})^{(12)(5)}$ and
