Determining the slope A(-1 ,3) B (-2 , 5 )

Mathematics
1 answer:
Helga [31]3 years ago

A(-1,3), B(-2,5)

Slope equation : (y₂-y₁) / (x₂-x₁)

Plug in the values into the equation.

AB = (5 - 3) / (-2+1)

Simplify.

AB = 2 / -1

AB = -2

So, your slope is -2.

~Hope I helped!~

-3+11p
first you add 1+2p that gets you -3 then you do 9p-4 and you get 11p from there you can either solve it, or leave it as is, depending on what your teacher wants.

How many solutions can be found for the system of linear equations represented on the graph?
Anon25 [30]

Answer:

No Solution

Step-by-step explanation:

As the two lines have the identical slope (-1/2x), that means these two lines are parallel, and therefore they have no solution.

22/100 in simplest form
lubasha [3.4K]

22/100:

You can actually divided the numerator and denominator by a number that can go into both 22 and 100 but also not get a remainder.

So 22/2= 11

And 100/2=50

Combined you get 11/50

Hope it helps!!!

Need answer for 6 and 7 question ASAP will give brainlist to who answered
Arturiano [62]

Answer:

6.  x = 2

7.  35721

Step-by-step explanation:

<h3><u>Question 6</u></h3>

Given equation:

8^{-4} \times 8^7=8^{2x-1}

\textsf{Apply the exponent rule} \quad a^b \cdot a^c=a^{b+c}:

\implies 8^{-4+7}=8^{2x-1}

\implies 8^{3}=8^{2x-1}

\textsf{Apply the exponent rule} \quad a^{f(x)}=a^{g(x)} \implies f(x)=g(x):

\implies 3=2x-1

Add 1 to both sides:

\implies 3+1=2x-1+1

\implies 4=2x

Divide both sides by 2:

\implies \dfrac{4}{2}=\dfrac{2x}{2}

\implies 2=x

Therefore, x = 2.

<h3><u /></h3><h3><u>Question 7</u></h3>

Given identity:

\sf (a-b)^2=a^2-2ab+b^2

To find the square of 189, rewrite 189 as (200 - 11).

Therefore, a = 200 and b = 11.

Substitute these values into the given identity and solve:

\begin{aligned}\sf (a-b)^2 & =\sf a^2-2ab+b^2\\\implies \sf 189^2 = (200-11)^2 & =\sf 200^2-2(200)(11)+11^2\\& = \sf 40000 - 400(11)+121\\& = \sf 40000-4400+121\\& = \sf 35600+ 121\\& = \sf 35721 \end{aligned}
