Bruno claims that the solution to the linear equation –3(2x + 6) + 25 = 1 is x = 1. He shows the steps below to justify his solution. Step 1:
Step 2:
Step 3:
Step 4:
-312x+6) + 28-1
-6 x - 18 +25 - 1
-6x + 7 = 1
-6 x = -6
x-1
Which of the following statements shows correct reasoning regarding the solution?
The solution is incorrect since Step 2 should be -6 - 43 = 1, so the correct solution is x = -7
The solution is correct since the solution x = 1 follows from the constant shown on the right side of the original equation
The solution is correct since the solution x = 1 follows from the equality of numbers asserted in each of the previous steps
The solution is incorrect since Step 1 should be -6 x + 18 + 25 = 1, so the correct solution is x = 7

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
