Answer:

Read on:

Step-by-step explanation:

Step 1:

  System #1

y=\frac{1}{2}x-2

y=-3x+5

  System #2

y=4x-3

y=4x-3

  System #3

y=\frac{-2}{3}x-1

y=\frac{-2}{3}x+2

Step 2:

  Look at First Drawing:

  Look at Second Drawing

  Look at Third Drawing

Step 3: Intersecting

Step 4: Overlap (Same Line)

Step 5: Parallel

Step 6:

  Intersecting: If the slopes are unequal

  Parallel: If the slopes are equal but the y-intercept is unequal

  Same line: If the slopes and y-intercepts are all equal

Step 7: The lines are parallel because although the slopes are equal, the y-intercepts are not

The graph of the function g(x)= x^2+3x-4 is shifted 5 units to the left
omeli [17]
<h2><em><u>HEYA</u></em></h2>

<h3>THE MID TERM SPLITTING OF THE EQUATION IS :</h3>

{x}^{2}  + 3x - 4

{x}^{2}  + 4x - x - 4

x(x + 4) - 1(x + 4)

x =  -4 \: and \: 1

x = 1

now shifted to 5 units left

therefore,

x=-4

hope it helps you mate thanks for the question and if possible please mark it as brainliest

What is 245,893 in scientific notation
s2008m [1.1K]
<span>The goal of writing a number in scientific notation is to have a decimal number, with one digit to theleft of the decmial point, followed by a × 10to some power.
</span><span>
To format your number in this way, we'll divide the 245,893 by 10, 2time(s), making it a 2.45.
We do this, because each division by 10 moves the decimal point to the left one digit.
But in order to keep our number the same number, we must have a × 102next to the 2.45.
</span><span>
So, the final answer is 2.45 × 10<span>2 (: Hope im right!</span></span>

What is the coefficient of the x^5y^5- term in the biomial expansion of (2x-3y)^10
jasenka [17]

<u>Answer:</u>

 The coefficient of x^{5} \times y^{5} \text { is }=\left(252 \times 2^{5} \times(-3)^{5}\right)=252 \times 32 \times 243=1959552

<u>Solution: </u>

The given expression is (2 x-3 y)^{10}

As per binomial theorem, we know,

(x+y)^{n}=\sum n C_{k} x^{n-k} y^{k}

Now here a = 2x, b = (- 3y) and n = 10 and k = 0,1,2,….10

Now x^{5}\times y^5 will be the 6 term where k =5

Now, \mathrm{T}_{6}=10 \mathrm{C}_{5} \times(2 \mathrm{x})^{(10-5)} \times(-3 \mathrm{y})^{5}=10 \mathrm{C}_{5} 2^{5} \times \mathrm{x}^{5} \times(-3)^{5} \times \mathrm{y}^{5}

So, the coefficient of x^{5} \times y^{5} \text { is }=10\left(5 \times 2^{5} \times(-3)^{5}\right.

10 \mathrm{C}_{5}=\frac{10 !}{5 ! \times(10-5) !}=\frac{10 !}{5 !+5 !}=\frac{10 \times 9 \times 8 \times 7 \times 6 \times 5 !}{5 ! \times 5 !}=\frac{10 \times 9 \times 8 \times 7 \times 6}{5 \times 4 \times 3 \times 2 \times 1}=\left(\frac{30240}{120}\right)=252

The coefficient of x^{5} \times y^{5} \text { is }=\left(252 \times 2^{5} \times(-3)^{5}\right)=252 \times 32 \times 243=1959552
