The rate of change is the slope.

That equation is (practically) in the form of y=mx+b because T(d) is very similar to y.

T(d) = 39.27d+36.77

y = mx+b

In this case, d would equal x. T(d) would equal y. 36.77 would equal b.

m is the slope, or the rate of change.

The rate of change is the variable, d, or the answer choice, a: the number of drinks purchased.

How to solve compound inequality

ElenaW [278]

first, you separate it into two inequalities.then, you determine whether the answer should be a union of sets or an intersection of sets. lastly, solve both inequalities and graph :)

I believe its 1/2 because m always stands for slope for slope formula

4. ABCD below is a rectangle. BE=6x+2 and ED=4x+6. Find the length of AC.

Nikolay [14]

Answer:

28 units

Step-by-step explanation:

ABCD is a rectangle. AC and BD are diagonals intersecting at point E.

Diagonals of a rectangle bisect each other.

$\therefore BE = ED$

$\therefore 6x + 2 = 4x + 6$

$\therefore 6x - 4x= 6-2$

$\therefore 2x= 4$

$\therefore x= \frac{4}{2}$

$\therefore x= 2$

$\therefore 6x + 2= 6*2+2= 12+2= 14$

$\therefore BE= 14\: units$

$\because BD = 2BE$

$\therefore BD = 2(14)= 28\: units$

$\because AC = BD$ (diagonals of a are equal in measure)

$\therefore AC = 28\: units$

Simplify this expression<br> 5*sqrt(x^22) where x<0

Doss [256]

Answer:

$\boxed{5x^{11}, x < 0}$

Step-by-step explanation:

$5\sqrt{x^{22}}$

Remember that we evaluate the term under the radical first.

Even though x < 0, x²² > 0

So,

$5\sqrt{x^{22}} = 5x^{11}$

The simplified expression is

$\boxed{5x^{11}, x < 0}$

Given that r||s and q is a transversal, we know that by the [________]. corresponding angles theorem alternate interior angles t

neonofarm [45]

Answer:

alternate interior angles theorem

Step-by-step explanation:

The alternate interior angles theorem states that when two parallel lines are cut by a transversal, the resulting angles produced are a pair of congruent alternate interior angles.

Given the image attached below, both line k and line l are parallel to each other and also, line t is the transversal, therefore the resulting congruent alternate interior angles produced are:

∠ 4 ≅ ∠6, ∠1 ≅ ∠7
