Answer:

no solution

Step-by-step explanation:

first you have expand the equation and so you will get

18x-12=18x+2

after you cancel 18x on both sides and so you will get

-12=2

and since that equation is false you will get

no solution

Answer:

rate of change is -1/3 (table) and 4 (graph)

Function 2 has the greater rate of change because the graph is steeper, and |4| is bigger than |-1/3|

Step-by-step explanation:

Answer:

(a) Function 1 : -2 Function 2 : 3.

(b) Function 2

Step-by-step explanation:

For function #1, you can calculate the rate of change (another word for slope) by counting the change between each y value. So, when x is 2, y is -3. When x is 3, y is -5. The rate of change is -2!

Show your work by marking an arrow for each y and writing -2.

Function #2, you need to find the slope (rate of change) by drawing a rise/run line when the equation line hits a point on the graph. One point is (-1,1) another point is (0,4). The slope/rate of change is 3.

Answer:

B

Step-by-step explanation:

Range is Y and the point is -4 to 2

The sum of the interior angles of a triangle is 180° is proved below.

We are given that;

To prove angle sum property of triangle

Now,

There are different ways to prove that the sum of the interior angles of a triangle is 180°. Here are three common proofs:

Proof : Using parallel lines and alternate interior angles

Since the line PQ is parallel to the side BC, and AB and AC are transversals, we can use the property that alternate interior angles are congruent.

Therefore, we have:

∠QAC = ∠ACB

∠PAB = ∠ABC

Adding these equations, we get:

∠QAC + ∠PAB = ∠ACB + ∠ABC

But ∠QAC + ∠PAB is a straight angle, which measures 180°. So, we have:

180° = ∠ACB + ∠ABC

Adding ∠CAB to both sides, we get:

180° + ∠CAB = ∠ACB + ∠ABC + ∠CAB

Simplifying, we get:

180° = ∠ACB + ∠ABC + ∠CAB

Hence, by the triangles the answer will be given above.

Answer with explanation:

The equation of a line passing through (a,b) and (c,d) is given by :-

[tex](y-b)=\dfrac{d-b}{c-a}(x-a)[/tex]

Equation of line passing through (2,-1) and (6,5) is given by :-

Jared and Pedro walked a total of 4.3 miles

        (multiply both sides by time)

        Distance = Speed × Time

        1 mile ÷ 15 = 0.06m/minute

        Distance = 0.06 × 65 = 4.3miles (rounded to the nearest decimal place)

The expression that most effectively represents u's value would be:

D). u = 2s

An expression is a sentence with a minimum of two numbers or variables and at least one math operation.

Given that,

In ΔABC,   E is the midpoint in the segment AC and  D is the midpoint of BC.

Now,

CE = 0.5 × AC(midpoint)

CD = 0.5 × CB (midpoint)

Thus,

CE/AC = CD/CB = ED/AB = 1/2        

As ED = s and AB = u

So,  u = 2s

Answer:

Step-by-step explanation:

Given

a) The volume formula will be:

As 150 is y-intersect (volume at zero time) and the rate of change (the slope) is 30 gal per hour

b) Increase of volume by percent:

30 gal increase on top of 150 gal

Answer:

20%

Step-by-step explanation:

The volume formula is V = 30t + 150 → where 150 is y-intersect and the slope is 30 gals per hour

So you can do:

30 gals of increase on top of the 150 gals to get:

30/150×100%  which equals 20%
