Solve the equation 3-x/5-4-x/2=1

Answers

Answer 1

Answer:

Hi Ponie

Simplify both sides of the equation

3-x/5-4-x/2=1

3+ -1/5 x+ -4+ -1/2 x =1

Combine like terms

(-1/5 x + -1/2 x)+(3+-4)=1

-7/10 x +-1=1

-7/10 x -1=1

Add 1 to both sides

-7/10 x-1+1=1+1

-7/10 x=2

Multiply both sides by 10/-7

(10/-7)*(-7/10 x )= (10/-7)*2

x= -20/7

I hope that's help and I am sorry for the late answer !

Find the center of the circle that can be circumscribed about ABC with A(0,0) B(6,0) C(6,4)

Answers

This can be solved by the distance formula.
If the center of the circle is at (h,k)
r² = (h - 0)² + (k - 0)²
r² = (h - 6)² + (k - 0)²
r² = (h - 6)² + (k - 4)²

Equating the equations
h² + k² = (h - 6)² + k²
h = 3

(h - 6)² + k² = (h - 6)² + (k - 4)²
k = 2

Therefore, the center of the circle is at (3,2).

a student was given the equation x^2+6x-13=0 the next step in the students process was x^2+6x+c=13+c state the value of c that creates a perfect square trinomial explain how the value of c is determined

Answers

This is the process of completing the square.
Keep this equation in mind: $ax^2+bx+c$
Basically, to make this a perfect square trinomial, you take half of b and square that value. This will make it so you can compress the left side of the equation into $(x+b)^2 \ or \ (x-b)^2$ depending on the sign in the middle of the original equation.

The total number of cookies needed for the bake sale is 812 dozen. Two of your friends will each bake 14 of the cookies. Your sister will bake 18 of the cookies. What fraction of the cookies do you need to bake?

Answers

Answer: $(28)/(51)$

Step-by-step explanation:

1 dozen = 12

Given, Total cookies needed = $8\frac12\ dozen = (17)/(2)\ dozen$

$=(17)/(2)* 12\n\n=102$

2 friends bake 14 cookies each, and your sister will bake 18.

So total cookies already assigned = 2 (14)+18

= 28 + 18 = 46

Remaining cookies you need to bake = 102 - 46 =56

Required Fraction = $\frac{\text{Number of cookies you bake}}{\text{Total}}=(56)/(102)=(28)/(51)$

Hence, fraction of the cookies you need to bake $=(28)/(51)$ .

What is the end behavior of the graph of the polynomial function f(x) = 2x3 – 26x – 24?

Answers

The degree of the function is 3, so it's odd. The leading coefficient is 2, so it's positive. Therefore, the end behavior of the graph of the functions is:
as x approaches negative infinity, f(x) approaches negative infinity
as x approaches positive infinity, f(x) approaches positive infinity

The end behavior of a polynomial function is the behavior of the graph of as approaches positive infinity or negative infinity. The degree and the leading coefficient of a polynomial function determine the end behavior of the graph.

Degree - 3 (odd);

Leading coefficient - 2 (positive).

Then

when $x\rightarrow -\infty,$ then $f(x)\rightarrow -\infty;$
when $x\rightarrow \infty,$ then $f(x)\rightarrow \infty.$

See attached graph of the function for graphical illustration.
