Answer:

<h2>This equation has no natural roots.</h2>

Step-by-step explanation:

3x^2+x-5=0\\\\\text{Use the quadratic formula for}\ ax^2+bx+c=0\\\\x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\\text{For the given equation:}\\\\a=3,\ b=1,\ c=-5\\\\b^2-4ac=1^2-4(3)(-5)=1+60=61\\\\x=\dfrac{-1\pm\sqrt{61}}{(2)(3)}=\dfrac{-1\pm\sqrt{61}}{6}\notin\mathbb{N}

5x + 2y = 7<br> –2x + 2y = –14
Anuta_ua [19.1K]
5x + 2y = 7....multiply by -1
-2x + 2y = -14
----------------
-5x - 2y = -7 (result of multiplying by -1)
-2x + 2y = -14
---------------add
-7x = - 21
x = -21/-7
x = 3

5x + 2y = 7
5(3) + 2y = 7
15 + 2y = 7
2y = 7 - 15
2y = - 8
y = -8/2
y = -4

solution is (3,-4)

Divide the difference of 20 and 6 by the product of 7 and 2
lukranit [14]

Step-by-step explanation:

<h3>Vocabulary (what the words mean):</h3>

Divide, the same as ÷

divide 6 <u>by</u> 3

<u>by</u> is the same as the symbol

6 ÷ 3 = 2

Difference, This is another way of saying take away or minus

the difference of 6 and 3 is

6 - 3 = 3

Product, This is another word for multiply or times

the product of 2 and 3 is

2 × 3 = 6

<h3>Write as an equation</h3>

divide <em>(÷)</em>  the difference of 20 and 6 <em>(20 - 6)</em> <u>by</u> the product of 7 and 2       <em>(7 × 2)</em>

<em />

<em>so </em>

<em>(20 - 6) ÷ (7 × 2)</em>

<em />

<em>can you do the rest???</em>

Can someone help me with this?
Arte-miy333 [17]

Answer:

(x-2)(x-2)

Step-by-step explanation:

You should be trying to find two numbers that add to make the coefficient of x (in this case, -4), and two numbers that multiply to make the constant term (in this case, +4). The two numbers that work for both of those criteria are -2 and -2.

-2 x -2 = +4 (satisfies the constant term)

-2 + -2 = -4 (satisfies the coefficient of x)

Some History teachers at Riverside High School are purchasing tickets for students and their adult chaperones to go on a field t
Mariana [72]

Answer:

Cost of student ticket =  $7

Cost of Adult ticket = $17

Step-by-step explanation:

Let cost of student ticket = x

Cost of Adult ticket = y

Making expressions from statements

Mrs. Levin bought 27 student tickets and 25 adult tickets, which cost a total of $614. 27x+25y=614

Mr. Lawson spent $733, getting 27 student tickets and 32 adult tickets. 27x+32y=733

Now solving these equations to find values of x and y

Let

27x+25y=614--eq(1)\\27x+32y=733--eq(2)

Subtracting both equations

27x+25y=614\\27x+32y=733\\-\:\:\:-\:\:\:\:\:\:\:\:\:\:\:\:-\\-------\\-7y=-119\\y=\frac{-119}{-7}\\y=17

So, we get value of y = 17

Now, finding value of x, by putting value of y in eq(1)

27x+25y=614\\Put\:y=17\\27x+25(17)=614\\27x+425=614\\27x=614-425\\27x=189\\x=\frac{189}{27}\\x=7

So, we get value of x = 7

Cost of student ticket = x = $7

Cost of Adult ticket = y = $17
