what is a triangle with a 90 degree angle

Answer:

Step-by-step explanation:

A.)  x² + 1 = 2x − 3   Make the equation into ax² + bx + c = 0. Subtract 2x on both sides, and add 3 on both sides to set the equation equal to 0

x² + 1 - 2x + 3 = 2x - 2x - 3 + 3

x² - 2x + 4 = 0      

a = 1

b = -2

c = 4    This is not the answer because b = 2 not -2, and c = -4 not 4

B.) x² - 2x − 1 = 3     Subtract 3 on both sides to set the equation = 0

x² - 2x - 4 = 0

a = 1

b = -2

c = -4      This is not the answer because b = 2 not -2

C. x² + 2x - 1 = 3    Subtract 3 on both sides to set the equation = 0

x² + 2x - 4 = 0

a = 1

b = 2

c = -4    This is your answer

D. x² + 2x - 1 = -3      Add 3 on both sides to set the equation = 0

x² + 2x + 2 = 0

a = 1

b = 2

c = 2       This is not the answer because c = -4 not 2

Hope this helps       :)

Answer:

M = 0

Step-by-step explanation:

Straight line is always slope of 0

Answer:

Step-by-step explanation:

Slope is defined as

m=(y2-y1)/(x2-x1) in this case

m=(5-5)/(5- -5)

m=0/10

m=0

This is a horizontal line, y=5, with a slope of zero.

Answer:

c. no solution

Step-by-step explanation:

This system of equations has no solution because when graphed, the lines are parallel to each other. Meaning they will never intersect. Since they will never intersect, there are no solutions.

Answer:

784000

Step-by-step explanation:

Given data

Profit =  700000

Let us begin by finding what 12% of  700000 is

=12/100* 700000

=0.12* 700000

=84000

Hence the profit made last years was

=84000+700000

=784000

Answer: 17°F

Step-by-step explanation:

Let the the town high temperature .In degrees Fahrenheit ,for January be represented by x

Since the town had low temperature for January was -8 Fahrenheit and the difference between the town high temperature and low temperature for January was 25. Then, the high temperature will be:

x - (-8) = 25

x + 8 = 25

x = 25 - 8

x = 17°F

Option C. 8 will be your answer

Answer:

y= 550-12x

Step-by-step explanation:

Given data

Content of tank= 550 gallons

Rate of drain= 12gallon per minute

let the time it will take to drain all 550 gallons be x minutes

Hence the expression for amount of water in the tank after x minutes will be

y= 550-12x

[tex]\frac{8}{10}[/tex] → [tex]\frac{4}{5}[/tex]

8 and 10 can both be divided by 2. So, 8 ÷ 2 is 4 and 10 ÷ 2 is 5.

Hope this helps :)

Answer:

4/5

Step-by-step explanation:

okay so to simplify, we first need to find the GCF of 8 and 10. The GCF of 8 and 10 would be 2. We now divide both 8 and 10 by 2. That will give us 4/5.

[tex]\frac{8}{10}[/tex]÷[tex]\frac{2}{2}[/tex]=[tex]\frac{4}{5}[/tex]

17.5

Step-by-step explanation:

Answer:

17.5

Step-by-step explanation:

Using Pythagoras theorem

X² = 15² + 9²

X² = 225 + 81

X² = 306

Take the square root of both sides

X = √306

X = 17.5

Answer:

p=x−7

Step-by-step explanation:

Let's solve for p.

px=x^2−7x

Step 1: Divide both sides by x.

px/x=x^2−7x/p

=x−7

Answer:

p=x−7

( I hope this was helpful) >;D

The value of p (x-1) is;

⇒ [tex]p(x - 1) = x^{2} -9x+8[/tex]

Here,

The function is given as;

[tex]p(x) = x^{2} -7x[/tex]

We have to find the value of p (x - 1).

What are the polynomials function?

A function that involves only non negative integer powers is called polynomial of function.

Now,

The function is given as;

[tex]p(x) = x^{2} -7x[/tex]

To find the value of p (x- 1), we can substitute x-1 in place of x, we get;

[tex]p(x-1) = (x-1)^2- 7(x-1)\\\p(x-1) = x^{2} -2x+1-7x+7\\\\\p(x-1) =x^{2} -9x+8[/tex]

Therefore, The value of p (x-1) is;

⇒ [tex]p(x - 1) = x^{2} -9x+8[/tex]
