plz help

Answers

Answer 1

Answer:

(x-2) 2

Step-by-step explanation:

Answer 2

Answer:

We see that the equation: x^2 - 4x + 4 is a perfect square trinomial as it is in the form of a^2 + 2ab + b^2, meaning that it is the square of a binomial. In this case, we see that we can multiply (x-2) with itself to obtain x^2 - 4x +4.

So the factored form is : (x-2)^2, or (x-2)(x-2)

We can check this by multiplying this out, and we obtain the same trinomial.

x^2-2x-2x+4

x^2-4x+4

Answer:

21 for the first one, 144 for the second

Step-by-step explanation:

If you're seeing the same problem I am in class, the rule is: N + 9

N is equal to 12 in this equation

12 + 9 is 21.

So, the answer is 21

If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-

Is 12(12)= 144

Hope this helps!

If f(x)=x+5, what is f-'(x)?

Answers

Step-by-step explanation:

Given

f(x) = x + 5

Let

y = f(x)

y = x + 5

Interchanging the roles of x and y we get

x = y + 5

y = x - 5

f^-1 (x) = x - 5

When solving this system by elimination, which variable is the most convenient to eliminate,
x or y?
2x + y = 7
3/2 x - y = 7/2

Answers

Answer:

Y is the appropriate variable and the most easiest and convenient to eliminate

name 2x + y = 7 as equation i

and 3/2 x - y = 7/2 as equation ii

then add equation i and ii together

(3/2 + 2) x + y - y = (7 + 7/2)

(7/2) x = (21/2)

x = 3

then put in x = 3 in equation i

4 + y = 7

x = 7 - 4

x = 3

Therefore x = 3 and y = 3

If the base angles of a triangle are congruent, use the Law of Sines to show the triangle is isosceles.

Answers

Answer:

The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!

The law of sins says: a/SinA = b/SinB = c/sinC

For this to be an isosceles triangle then side a must equal side c

so then a/sinA = c/sinC

Then you can divide both sides by a and raise to the power of -1 and you would get angle A = angle C which makes this isosceles.

Write an equation in point-slope form for the line through the given point with the given slope. (3,−4);m=−14

Answers

Answer:

y=-14x-4

Step-by-step explanation:

Answer:

y + 4 = - 14(x - 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = - 14 and (a, b ) = (3, - 4 ) , then

y - (- 4) = - 14(x - 3) , that is

y + 4 = - 14(x - 3)

Answer:

  12

Step-by-step explanation:

The prime factorization of 144 is ...

  144 = 9·16 = 2·2·2·2·3·3

Grouping pairs of similar factors, we have ...

  144 = (2·2)·(2·2)·(3·3) = (2·2·3)·(2·2·3) = 12·12

  √144 = √(12²) = 12

Mega Movies hosted a film premiere on Friday night. They charged $7 for adults and $4 for
children. Ninety-four adults and children attended, and $592 was made in ticket sales. How
many children and how many adults went to the film premiere?

Answers

Answer:

72 adults

22 children

Step-by-step explanation:

Let c = no. of children

     a = no. of adults

Then 4c = total sales for the children and

         7a = total sales for the adults

So,   a + c = 94      and 7a + 4c = 592  

                                    -4a - 4c = -376

                                      3a = 216

                                        a = 72 adults

        72 + c = 94

                c = 22 children
