in what step did audrey make her mistake in
Answer:
step A
Step-by-step explanation:
she should have added x to both sides.
Answer:
-x+6=5x+30
6=6x+30
6x=-24
x=4
if you want to get rid of the -x you have to add x not take away x

Please help, we're supposed to be writing an equation from the table here. But I don't know.
Answer:
y = 3x - 3
Step-by-step explanation:
This more of a guess than a reality of method. You have to try and guess which number when multiplied by 4 will give 9. It won't happen directly.
The best clue is provide by (0,-3).
So let's start with a general linear equation.
y = mx + b
If you put in 0 for x then mx disappears and you are are left with y = - 3
That means that b = - 3
So now you have
y = mx - 3
Now try another one
y = mx - 3
y = 9
x = 4
9 = mx - 3
9 = 4m - 3 Add 3 to both sides
9+3 = 4m-3+3 Combine
12 = 4m Divide by 4
12/4 = 4m/4
3 = m
So the equation you want so far, is y = 3x - 3 Does it work for anything else?
Try - 3 , - 12 . If it works for this, it should work for anything.
y = 3*-3 - 3
y = -9 -3
y = - 12
and it does work, so that's your answer.
can someone help? No explanation needed :')

Find the value of c that makes the trinomial a perfect square: x^2– 40x + c
Answer:
c=400
Step-by-step explanation:
Use the perfect square formula:
ax^2+bx+c=0
x^2-40x+c=0
bring c to the other side
x^2-40x+___=-c
divide -40 by 2 then square it; 400
add 400 to each side
c=400
(x-20)(x-20)
The value of c that makes the trinomial a perfect square x²– 40x + c is 400.
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
We have to find the value of c that makes the trinomial a perfect square: x²– 40x + c
Lets use the perfect square formula:
ax²+bx+c=0
The given equation is given below.
x²-40x+c=0
Take the c term to the right hand side
x²-40x=-c
x²-40x+400=-c+400
c=400
Hence, the value of c that makes the trinomial a perfect square x²– 40x + c is 400.

What is the area of a room that is 3 3/4 yards long by 3 1/3 yards wide?
Answer:
Depends on what your question asks for (in mixed or improper form) your answer would be: 150/12 yards or 12 1/2 yards
brainliest please?<3
Step-by-step explanation:
To find the area, first convert the mixed numbers to improper form:
3 3/4 = 15/4 & 3 1/3 = 10/3
Now multiply them together:
15/4 x 10/3
= 150/12
Answer: 12.5

Write an inequality that represents the graph below:
Answer:
x< 0
Step-by-step explanation:
[] An open circle means we will be using < or > and not ≤ or ≥ because the number is not included in the inequality
[] The direction of the inequality sign will go in the direction of the graph, so we will be using < as our number is less than the value given
[] Our final answer, assuming we can use x for this graph, is x < 0
