Find the value of r 4(x-3) -r +2x =5(3x-7) -9x <br> Please help me

lbvjy [14]

$4(x-3)-r+2x=5(3x-7)-9x\ \ \ |\text{use distributive property}\\\\(4)(x)+(4)(-3)-r+2x=(5)(3x)+(5)(-7)-9x\\\\4x-12-r+2x=15x-35-9x\\\\(4x+2x)-12-r=(15x-9x)-35\\\\6x-12-r=6x-35\ \ \ \ |-6x\\\\-12-r=-35\ \ \ \ |+12\\\\-r=-23\to\boxed{r=23}$

Please help me with this

Answer:

For the question on the right, I assume b is the exponential factor, or growth factor.

Step-by-step explanation:

Linear:

$Y=aX + b\\(X, Y) = (0, 15) => b = 15\\(X,Y) = (1, 12) => a = -3\\Y = -3X + 15$

You can find the equation by using two points and the equation for a line.

Exponential:

$Y = a^{bX+c}\\(X, Y) = (0, 81) => a^{c} = 81 => a^{c} = 3^{4} => a=3, c=4\\(X, Y) = (1, 27) => a^{b+c} = 27 => a^{b}a^{c} = 27 => a^{b} = \frac{27}{81} = \frac{1}{3} => b=-1\\Y = 3^{-X+4}$

<1 and <2 are supplementary angles. The measure of <1 is 87º. The measure of <2 is 15x + 18º.

Kay [80]

Answer: x= 5

Step-by-step explanation: If angles 1 and 2 are supplementary, that means they add up to 180. So if angle 1 is 87, angle 2 has to be 180-87=93. Then the equation would be 15x+18=93. Subtract 18 on both sides. 15x=75. Divide by 15 and your answer is 5.
