Answer: x=\frac{23}{4} and  x=-\frac{17}{4}

Step-by-step explanation:

Given the equation |4x - 3| = 20, you can set up two cases:

Case 1: 4x-3>0

4x-3=20

Solve for the variable "x", therefore you get:

4x=20+3\\\\x=\frac{23}{4}

Case 2: 4x-3

-4x+3=20

Solve for the variable "x". Then, you  get:

-4x=20-3\\\\x=\frac{17}{-4}\\\\x=-\frac{17}{4}

Therefore, the solution is:

x=\frac{23}{4} and  x=-\frac{17}{4}

3/8x+1/3y=17/24<br> X+7y=8
guajiro [1.7K]
Multiplying the first equation and multiplying it by -8/3 (to get rid of the x), we get -8y/9+7y= -64+8=-56. Therefore, -56/(-8/9+7)=y and 8- 7(-56/(-8/9+7))=x by plugging it into the second equation

If h(x) = x – 7 and g(x) = x2, which expression is equivalent to (5 – 7)2 (5)2 – 7 (5)2(5 – 7) (5 – 7)x2
rodikova [14]
E are given with two functions: h(x) = x – 7 and g(x) = x2. In this problem, we are asked to determine the value of g(h(5)). first we get g(h(x)) which is equal to (x-7)2, when x is substituted by 5, then g(h(5)) = (5-7)^2 equal to 4
