What is the value of x in the equation 3x -1/9<br> y = 18, when y = 27?<br> 5<br> 7<br> 45 63

almond37 [142]

Answer:

$x=7$

Step-by-step explanation:

we have

$3x-\frac{1}{9}y=18$

Substitute the value of y=27 in the equation and find the value of x

$3x-\frac{1}{9}(27)=18$

$3x-3=18$

$3x=18+3$

$3x=21$

$x=7$

Put answer in coordinate form: 2x + 2y = -2 and 9x - 6y = 36

zhannawk [14.2K]

Coordinate form is (x,y) using the variables respectively.

2x+2y=-2
-2y
2x= -2-2y
/2

x=-1-y

9x-6y=36
9 (-1-y)-6y=36
-9-9y-6y=36
+9.
-9y-6y=45
-15y=45
/-15
y=-3

x=-1-y
x=-1- (-3)
x=2

answer: (2,-3)

Answer:

f(-2) = 90

Step-by-step explanation:

Plugging in the value of f(x) into the equation:

f(-2) = 5(-2)3^(-2)

f(-2) = 5(-2)(-9) - evaluate the power first

f(-2) = 90 - multiply from left to right to obtain answer
