Pablo folds a straw into a triangle with side lengths of 4x2 – 3 inches, 4x2 – 2 inches, and 4x2 – 1 inches. The perimeter of the triangle is 12x2 – 6 inches. If x = 1.5, what was the length of the straw before it was folded?

Answers

side 1 : 4x² - 3 inches
side 2 : 4x² - 2 inches
side 3 : 4x² - 1 inches

perimeter = 12x² - 6 inches

x = 1.5

12(1.5²) = 12(2.25) = 27 inches

I think the length of the straw before it was folded was 27 inches. - 6 inches is the fold of the straw.

Find the value of y when x equals 2 , -8x-5y=1

Answers

-8x - 5y = 1
when x = 2
-8(2) - 5y = 1
-16 - 5y = 1
5y = -16 - 1 = -17
y = -17/5

Which represents the solution(s) of the system of equations, y = x2 – 4x – 21 and y = –5x – 22? Determine the solution set algebraically.(–1, –17)

(–1, –17) and (1, –27)
no solutions

Answers

Answer:

D. No solutions.

Step-by-step explanation:

We have been given a system of equations and we are asked to find the solution set for our given system.

$y=x^2-4x-21$

$y=-5x-22$

To find the solution for our given system we will equate our both equations as:

$x^2-4x-21=-5x-22$

$x^2-4x+5x-21=-5x+5x-22$

$x^2+x-21=-22$

$x^2+x-21+22=-22+22$

$x^2+x+1=0$

We will use discriminant formula to check for the solution of our given system.

$√(b^2-4ac) \geq 0$ for real solutions.

Upon substituting our given values in above formula we will get,

$√(1^2-4*1*1) \geq 0$

$√(1-4) \geq 0$

$√(-3) \ngeq 0$

Therefore, our given system has no solutions and option D is the correct choices.

Determine the function's value when x = -1.O g(-1) = -3
Og(-1) = 0
O g(-1) = 1
Og(-1) = 27

Answers

The value of function's when x = -1 is,

⇒ g (- 1) = 1

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;'

The function is,

⇒ g (x) = x³ + 6x² + 12x + 8

Now, Substitute x = - 1 in above function, we get;

⇒ g (x) = x³ + 6x² + 12x + 8

⇒ g (-1) = (-1)³ + 6 (-1)² + 12 (-1) + 8

⇒ g (-1) = - 1 + 6 - 12 + 8

⇒ g (-1) = 1

Thus, The value of function's when x = -1 is,

⇒ g (- 1) = 1
