36 squared-46-22=0 quadratic formula

Mathematics

Your question isn't quite formatted correctly to be a quadratic equation as it has no variable for the "a" and "b" terms but I'll just insert them and hopefully it will match what you're asking. 

Let x be our variable. 

36x² - 46x - 22

The quadratic formula for a quadratic equation in the format ax² + bx + c = 0 is:

x =  \frac{- b +/-  \sqrt{b^{2} - 4ac} }{2a}

Now we just insert our terms to the formula:
x =  \frac{46 +/-  \sqrt{(-46)^{2} - 4(36)(-22)} }{2(36)}

And now we solve:
x =  \frac{46 +/-  \sqrt{2116 + 3168}}{72}
x =  \frac{46 +/-  \sqrt{5284}}{72}
x =  \frac{46 +/-  2\sqrt{1321}}{72}

Your final answers when you simplify:

x =  \frac{23 +  \sqrt{1321} }{36} and x =  \frac{23 -  \sqrt{1321}}{36}

Answer:

Part 3) Miguel scored 29 points and Alonzo scored 25 points

Part 4) Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years

Step-by-step explanation:

Part 3) Let

x ----> the number of points that Miguel scored

y ---> the number of points that Alonzo scored

we know that

x+y=54 ----> equation A

x=y+4 ----> equation B

substitute equation B in equation A and solve for y

(y+4)+y=54\\2y=54-4\\2y=50\\y=25

Find the value of x

x=25+4=29

the solution is the point (29,25)

That means ----> Miguel scored 29 points and Alonzo scored 25 points

Part 4) Let

x ----> Morgan's age

y ---> Mr Santos' age

we know that

x+y=44 -----> equation A

x=y-15 ----> equation B

substitute equation B in equation A and solve for y

(y-15)+y=44\\2y=44+15\\2y=59\\y=29.5

Find the value of x

x=29.5-15=14.5

the solution is the point (14.5,29.5)

That means ----> Morgan's age is 14 1/2 years and Mr Santos' age is 29 1/2 years

Solve the system of linear equations by elimination.<br><br> x+4y=1<br> 3x+5y=10
laiz [17]

Answer:

x = 5 , y = -1

Step-by-step explanation:

Solve the following system:

{4 y + x = 1 | (equation 1)

5 y + 3 x = 10 | (equation 2)

Swap equation 1 with equation 2:

{3 x + 5 y = 10 | (equation 1)

x + 4 y = 1 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:

{3 x + 5 y = 10 | (equation 1)

0 x+(7 y)/3 = -7/3 | (equation 2)

Multiply equation 2 by 3/7:

{3 x + 5 y = 10 | (equation 1)

0 x+y = -1 | (equation 2)

Subtract 5 × (equation 2) from equation 1:

{3 x+0 y = 15 | (equation 1)

0 x+y = -1 | (equation 2)

Divide equation 1 by 3:

{x+0 y = 5 | (equation 1)

0 x+y = -1 | (equation 2)

Collect results:

Answer: {x = 5 , y = -1

15 points PLEASE HELP!!!<br><br> Factor the following equation:<br> <img src="https://tex.z-dn.net/?f=x%5E2%2B3x%2B4" id="TexFor
ycow [4]

Step-by-step explanation:

x²+3x+4=0

x²+3x_ +2=0

x²+3x_2=-2

x²+3x_2+(3x_4)²=-2+(3/4)²

(x+3/4) =-2+9_16

x+3_4 = -32+9__16 =√-23_6

x+3_4 =-√23_4

x = -3+√-23___4

x = -3- √-23___4 , -3+√-23___4 //
