The answer is the last choice. It says the triangle is dilated by a scale factor of $\frac{1}{4}$ . To check this we can just look at the side lengths if the triangles. $AB$ has a length of 8 by looking at the graph, and $A'B'$ has a length of 2 from the graph too. So when we put those lengths $\frac{2}{8}$ into a fraction, it simplifies to $\frac{1}{4}$ . The only answer that says this is the last answer choice.

Triangle ABC is similar to triangle A prime B prime C prime. because triangle A prime B prime C prime. is obtained by dilating Triangle ABC.by a scale factor of 1 over 4. and then rotating it about the origin by 180 degrees

If f(x) is defined as follows,

Phantasy [73]

Answer: The required values are

f(-2) = 120, f(0) = 64 and f(1) = 84.

Step-by-step explanation: We are given the following function f(x) :

$f(x)=16x^2+4x+64~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We are to find the values of the following :

$(a)~f(-2),\\\\(b)~f(0),\\\\(c)~f(1).$

To find the values of the function at the given points, we need to substitute the corresponding values of x in equation (i).

Substituting x = -2 in equation (i), we get

$f(-2)=16\times(-2)^2+4\times(-2)+64=64-8+64=120.$

Substituting x = 0 in equation (i), we get

$f(0)=16\times0^2+4\times0+64=0+0+64=64.$

Substituting x = 1 in equation (i), we get

$f(1)=16\times1^2+4\times1+64=16+4+64=84.$

Thus, the required values are

f(-2) = 120, f(0) = 64 and f(1) = 84.

Factorise <br> a) 4p²-81<br> b) x²-13x+36

taurus [48]

Answer:

A = (2p + 9) (2p - 9)

B = (x - 9) (x - 4)

Step-by-step explanation:

For A : Rewrite 4p^2 as (2p)^2.

(2p)^2−81

Rewrite 81 as 9^2.

(2p)^2−9^2

Since both terms are perfect squares, factor using the difference of squares formula, a^2 − b^2 = ( a + b ) ( a − b ) where a = 2p and b = 9 .

(2p + 9) (2p − 9)

For B : Consider the form x^2 + bx + c . Find a pair of integers whose product is c and whose sum is b . In this case, whose product is 36 and whose sum is − 13 .

-9, -4

(x - 9) (x - 4)

I hope this helps.

Is -2x-6=2x+6 no soulution

Olegator [25]

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

−2x−6=2x+6

Step 1: Subtract 2x from both sides.

−2x−6−2x=2x+6−2x

−4x−6=6

Step 2: Add 6 to both sides.

−4x−6+6=6+6

−4x=12

Step 3: Divide both sides by -4.

−4x/−4 = 12/-4

x=−3
