THE OPPOSITE of -7 would be 7. -7 is a negative, and the opposite of a negative is a positive, and so the opposite of -7 would be 7 (which is positive 7.)

Need help on solving this ?
katovenus [111]
For the first question, simply plug in the value of 3 into the polynomial question. The final answer is your volume of the hot water tub.

For the second question, you can figure out that x = -5 is not a real root because it does not touch or cross the x axis.

If it does it would be an solution.

Simplify 26-18b+11(b-3)
xxMikexx [17]

Answer:

<u>-7b-7</u>

Step-by-step explanation:

First you have to distribute 11 throughout the parentheses.

26-18b+11(b-3)\\26-18b+11b-33

Now we can combine like terms. (-18b, 11b, -33, 26)

-18b+ 11b  and -33+26

-7b-7

This is your simplified answer for your expression.

<u>-7b-7</u>

Answer:

An equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

  • y=-6x+7

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

Given the equation

6x+y=6

Writing in the slope-intercept form of the line equation

y = -6x + 6

comparing with the slope-intercept form of the line equation

y = mx+b

Thus, the slope of line = m = -6

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line is also -6.

As the line passes through the point (2,−5).

Thus, using the point-slope form of the line equation

y-y_1=m\left(x-x_1\right)

where m is the slope and (x₁, x₂) is the point

substituting the values m = -6 and the point (2,−5)

y-y_1=m\left(x-x_1\right)

y - (-5) = -6 (x - 2)

y+5=-6\left(x-2\right)

subtract 5 from both sides

y+5-5=-6\left(x-2\right)-5

y=-6x+7

Therefore, an equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

  • y=-6x+7
