Answer:
D. infinitely many solutions
Step-by-step explanation:
to find how many solutions the equation have, we can solve it
here's the given equation:
2(2x-3)+6=4x
our goal is to isolate the variable onto one side
do the distributive property shown in the equation (multiply both 2x and -3 by 2)
4x-6+6=4x
combine like terms (add -6 and 6)
4x=4x
subtract 4x from both sides, as we still have the variable on both sides
0=0
0 is always equal to 0; that's an identity
if we get to a point in an equation where we get an identity as the answer (ex. 3=3 or in this case, 0=0), the answer is all real numbers, or infinitely many solutions
Answer:
-10,-4
Step-by-step explanation:
Use the midpoint formula also plz give brainliest
F(x) = 1/2x +4
replace f(x) with y
y = 1/2x+4
switch x and y
x = 1/2y +4
solve for y
multiply both sides by 2
2x = y+8
subtract 8 from both sides
2x-8 = y
rewrite with y on the left side: y = 2x-8
replace y with f(x)^-1 (inverse notation)
f(x)^-1 = 2x-8
solve for f^-1(4)
replace x with 4 in the equation and solve:
2(4) -8 = 8-8 = 0
1) The Maximum amount of minutes that Chad can run for each kilometer is 5 minutes. 2) A member has spent $50 at a gym, The charge without swimming is $30 per month. So the gym member has spent another $20 and divide by $4 and the member can swim for a total of 5 hours.

Answer:
Slope = 4/9
Step-by-step explanation:
The slope formula is ...
m = (y2 -y1)/(x2 -x1)
m = (6 -2)/(5 -(-4)) = 4/9
The slope is 4/9.
