How many solutions does this equation have? 3(n + 4) = 3n + 11

Mathematics

1 answer:

Basile [38]3 years ago

4 0

Answer:

No solution.

Step-by-step explanation:

3(n + 4) = 3n + 11

Distribute on the left side.

3n + 12 = 3n + 11

Subtract 3n from both sides.

12 = 11

Since 12 = 11 is a false statement, there are no solutions.

Answer:

Psychology textbooks = 98 and physics textbooks = 294

Step-by-step explanation:

Let there are x psychology textbooks sold.

No of physics textbooks sold = 3x

ATQ,

A textbook store sold a combined total of 392 physics and psychology textbooks in a week.

x + 3x = 392

4x = 392

x = 98

It means there are 98 psychology textbooks sold and 3x = 3(98) = 294 physics textbooks sold.

write the slope-intercept form of the line that passes through the point (1,0) and is parallel to x-y=7. type your answer in the

Brilliant_brown [7]

Parallel lines have the same slope but different y intercepts.
turn x-y=7 into slope intercept form by isolating y which would be -y=-x+7
divide the equation by -1 in order to make y positive and you get y=x-7
So rewrite the equation with the same slope but this time solving for b
y=x+b
plug in your coordinates
0=1+b
subtract 1 from both sides
-1=b
so your equation would be
y=x-1
