Ugh I’m going insane trying to do this. Please help.
olga nikolaevna [1]

Answer:

y(x)=6^(x)-3

Step-by-step explanation:

Let the exponential function be y(x) = ab^(x) but since the graph is translated 3 units down, y(x) = ab^(x)-3. Now, y(0)=-2=a*b^(0)-3. a=1. The equation is nearly complete but we need b, we can find it by using the point y(1)=3. y(x)=b^(x) - 3. y(1)=3=b-3, b=6. The equation of the function is y(x)=6^(x)-3

Pls pls pls answer! I will mark brainliest!!!! tysm<br> xy = 72<br> (x + 2)(y - 4) = 128
zheka24 [161]

Answer:

x=2 and y=36

Step-by-step explanation:

you have two equations

1) xy=72 and 2) (x+2)(y-4)=128

solve for one of the variables in equation 2), lets do y

(x+2)(y-4)=128, divide by (x+2) to both sides and add 4 to isolate variable y

therefore, y=(128/(x+2))+4

then plug in y into equation 1)

so x(our new y)=72

x( 128/(x+2) +4 )=72

distribute the x so you will get

(128/(x+2))x +4x=72

we are now solving for x, so isolate the x by subtracting 4x and multiplying by (x+2) to get

128x=(x+2)(72-4x)

multiply by distribution and combine like terms

-4x^2 -64x +144 =0

solve for x by quadratic formula, you'll get x=2 or x=-18

substitute back into equation 1), (2)(y)=72, solve for y to get 36

then you can check by substituting back into equation 2)

(2+2)(36-4)=128

(4)(32)=128, 128=128

In your own words write the rules for multiplying integers
Harrizon [31]
Positive=+
negative=-
(+)(+)=(+)
(-)(-)=(+)
(+)(-)=(-)
(-)(+)=(-)

\frac{(+)}{(+)}=(+)
\frac{(-)}{(-)}=(+)
\frac{(+)}{(-)}=(-)
\frac{(-)}{(+)}=(-)

that is regarding the signs

the rest is the same
and any integer times 0=0
