Step-by-step explanation:
x= 3/8 = 0.375 , x= -4/5= -0.8
8x-3=0
8x=3
8x/8 = 3/8
x= 3/8 converted to decimal will be =0.375
for 5x+4=0
5x= -4
5x/5 = -4/5
x= -4/5 = converted to decimal will be = -0.8
Slope=4/5
This is the formula to find the slope of lines:
y2-y1/x2-x1 (look it up to learn more)
9-1/1+9
8/10
4/5
The slope is 4/5
Hope this helps :)
Answer: 78
(The solution is (4, -11).
Step-by-stp explanation:
Let f(x) = g(x) = y:
y = 3x − 23
y = -4.5x + 7 Subtract the second equation from the first to eliminate y:
0 = 7.5x - 30
7.5x = 30
x = 4
Plug this into the first equation:
y = 3(4) - 23
y = -11.
