Will mark brainliest!! solve & simplify the following equation: 2x²-7x=4

Answers

Answer 1

Answer:

Answer:

x= −1/2 or x=4

Step-by-step explanation:

This is ALGEBRA, equations, factoring and zero property. ok.. let's solve this step-by-step

2x^2−7x=4

Step 1: Subtract 4 from both sides.

2x^2−7x−4 =4 −4

2x^2−7x−4=0

Step 2: Factor left side of equation.

(2x+1)(x−4)=0

Step 3: Set factors equal to 0.

2x+1=0 or x−4=0

x= −1/2 or x=4

(BTW, there are supposed to be two answers, it's factoring)

Sorry if the format is not clear, but I hope this helped (really feel you, algebra can be brain-striking)!! Please leave a comment, rating and/or mark as the brainliest-whichever you think I deserve! Thank You :)

Mario has a business selling muffins. Let x be the price of a muffin. Then, the profit P for Mario’s business is given by p(x)=-100x2+350x-150 Choose the inequality that shows the business will make a positive profit.

Answers

The first question's answer is:

0<-100x^2+350x-150

The second question "Look at the factorization shown below.

0 < –100x2 + 350x – 150

0 < –50(2x2 – 7x + 3)

0 < –50(2x – 1)(x – 3)

Select the range that Mario can choose from to price his muffins and make a positive profit.

Polynomial function in standard form with zeros 5,-4,1

Answers

Answer:

$\boxed{\sf \ \ \ x^3-2x^2-19x+20 \ \ \ }$

Step-by-step explanation:

hello,

by definition we can write

$(x-5)(x+4)(x-1)$

as 5,-4,1 are the zeroes

now we have to write it in the standard form, let's do it

$(x-5)(x+4)(x-1)=(x^2+4x-5x-20)(x-1)\n=(x^2-x-20)(x-1)=x^3-x^2-20x-x^2+x+20\n=x^3-2x^2-19x+20$

hope this helps

SOLVING QUADRATIC EQUATIONS BY SQUARE ROOT
4m^2-1=-23

Answers

4m^2-1=-23
⇒ 4m^2= -23+1
⇒ 4m^2= -22
⇒ m^2= -22/4
⇒ m^2= -11/2
⇒ m is undefined for all m∈R (for m^2 is always ≥0 for all m∈R)

Final answer: m is undefined for all m∈R~

4m^2 -1 = -23 Add 1 to both sides 4m^2 = -22 then divide both sides by 4. m^2 = -11/2. Square root both sides. m = ((square root of 22)/2) times i
