Answer:

The slope of this line is 1021.

Step-by-step explanation:

A regression line has the following format:

y = b + ax

In which a is the slope, that is, how much y changes with a variation of a single unit in x.

In this problem, our line is:

forest loss=7500+1021x

In which x is the number of years after 2000.

So the slope of this line is 1021.

How many solutions does the equation 3x − 7 = 4 + 6 + 4x have
Sunny_sXe [5.5K]

Answer:

The given equation 3x − 7 = 4 + 6 + 4x has one solution.

Step-by-step explanation:

Given : Equation 3x − 7 = 4 + 6 + 4x

We have to find the number of solutions of the given equation.

Consider the given equation 3x − 7 = 4 + 6 + 4x

Simplify, we have,

3x − 7 = 10 + 4x

Now subtract 3x both side, we hvae,

-7 = 10 + 4x - 3x

Simplify, we have,

- 7 = 10 + x

Subtract 10 both side, we have,

-7 - 10 = x

x = - 17

Thus, The given equation 3x − 7 = 4 + 6 + 4x has one solution.

Solve for x. 3/4 = x/12 <br> I need work shown to
marta [7]

\frac{3}{4} = \frac{x}{12}

To solve for x you have to bring the 12 to the other side

How  do we do this?

Well if you think about it this is technically what the equation shows

\frac{3}{4} = x * \frac{1}{12}

This means to isolate x you can multiply both sides by 12 and that will cancel \frac{1}{12} from the right side

\frac{3}{4} * 12 = x * \frac{1}{12} * 12

\frac{36}{4} = x * 1\\\frac{36}{4}  = x

\frac{36}{4} can be further simplified to...

9

^^^This is the answer

Check:

3/4 = 9/12

3/4 = 3/4

Hope this helped!

Maristella is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 cm.
Vlada [557]

Isolating s, the equation written in terms of s is:

s = 12 - 0.5b

-------------------------

  • The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

b = 24 - 2s

  • To solve for the lengths of the congruent sides, we isolate s, thus:

b = 24 - 2s

2s = 24 - b

Inverse of multiplication is division, thus:

s = \frac{24 - b}{2}

Separating into two fractions:

s = \frac{24}{2} - \frac{b}{2}

Solving each fraction:

s = 12 - 0.5b
