Solve for x, then find mZY. Justify your answer.
X
(6x – 23)
Y
(4x + 9)
Z

 y = z and y = 137/5

Step-by-step explanation: From the equation xy = xz, x cancels out on both ends so you end up with y = z.

Additionally, you can use the second equation, x = 6x - 23 and simplify it to 5x = 23, then x = 23/5.

You can then plug in that value of x into the third equation: z = 4(23/5) +9, then z = 92/5 + 9, then z = 137/5

Since z = y, this applies to y as well

Therefore, y = z and y = 137/5

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
