-7 - -3(x+3)>5 how do I work this problem

Mathematics
1 answer:
charle [14.2K]3 years ago
5 0

Answer:

x > 1

Step-by-step explanation:

It's actually a pretty simple algebra problem, you can pretend the > is an = for the most part.  The only difference is if you ever multiply or divide by a negative you flip the direction

-7 + 3(x+3)>5 (as long as that double minus sign was accurate)

-7 + 3x + 9 > 5

2 + 3x >5

3x > 3

x > 1

Now, like I mentioned if you divide or multiply by a negative the inequality flips.  so say you multiply by -1 on both sides you will get -x < -2.  I just want to make sure you remember that because it can be hard to remember.

Write the equation that represents the line that goes through the point (5, -7) and has slope m=-3
RUDIKE [14]

Answer:

<u>y = -3x + 8</u>

Step-by-step explanation:

<u>Given :-</u>

Point on line = (5, -7)

Slope (m) = -3

<u>To find :-</u>

Equation of line

<u>Solving :-</u>

Using point-slope form of equation,

y - y₁ = m(x - x₁)

y + 7 = -3(x - 5)

y + 7 = -3x + 15

<u>Solution :-</u>

<u>y = -3x + 8</u>

Find a whole number x in x/113 so that the ratio is a good estimate for pi
NISA [10]
So the initial question is x / 113 = 3.14 (we're keeping it a smaller decimal for now)

What you should do first is multiply both sides by 113

Your answer should be x = 354.82

Round this up to x = 355. <-- This is why we only used 3.14 at the start

Now check your work:
x / 113 = ?
355 / 113 = 3.14159265358979... which essentially is pi

A line has a slope of 1/4 and passes through point (0.4,-1/2). What is the value of the y-intercept?
AVprozaik [17]

Answer: The value of the y-intercept is -\frac{3}{5}

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

In this case we know that the line passes through point (0.4,-\frac{1}{2}) and has a slope of \frac{1}{4}. Then we can substitute the following values into  y=mx+b:

x=0.4\\\\y=-\frac{1}{2}\\\\m=\frac{1}{4}

Then:

-\frac{1}{2}=\frac{1}{4}(0.4)+b

And finally, we must solve for "b":

-\frac{1}{2}=\frac{1}{4}(0.4)+b\\\\-\frac{1}{2}-\frac{1}{10}=b\\\\b=-\frac{3}{5}
