Mathematics
1 answer:
ruslelena [56]3 years ago
8 0

Answer:

C' = (2,8)

A' =  (4,4)

T' = (10,10)

Step-by-step explanation:

Given

k =2

C =(1,4)

A = (2,2)

T =(5,5)

Solving (a): The new points

To do this, we simply multiply the old points by the scale factor.

i.e.

New = Old * k

So:

C' = (1,4) * 2 = (2,8)

A' = (2,2) * 2 = (4,4)

T' = (5,5) * 2 = (10,10)

Solving (b): The graph of the original image

Simplify The Complex Fraction. 6/7 over 1/7 ​
Likurg_2 [28]

Answer: 6

Step-by-step explanation:

6/7 divided by 1/7 would be the same as 6 times 7 over 7 times 1 because to divide fractions you multiply by the reciprocal etcetera. Therefore, the fraction would become 42/7 which, if simplified, gives you 6/1, and thus the answer of one. Hope this helps!

The midpoint of AB = ([?], [])<br> M = (x¹+x², ¹2²)<br> PLS HELP I WILL MARK BRAINLIEST
OlgaM077 [116]

Answer:

\sf M=\left(-\dfrac{1}{2},0\right)

Step-by-step explanation:

Let (x₁, y₁) = Point A = (-2, 1)

Let (x₂, y₂) = Point B = (1, -1)

\sf Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)

\implies \sf Midpoint=\left(\dfrac{-2+1}{2},\dfrac{1+(-1)}{2}\right)

\implies \sf Midpoint=\left(-\dfrac{1}{2},0\right)

i dont know how to solve this questions without a graphing on a calculator but i can't use calculator for this question pls help
hoa [83]

Answer:

<em><u>D</u></em>

Step-by-step explanation:

When the denominator is equal to 0, the function doesn't exist. So factor the bottom, luckily its already partially factored.

(x^2 + 8x + 12) = (x+2)(x+6)

So now the denominator is (x+2)(x+6)(x-3)

The function doesn't exist when x = -2, -6, 3

Now we know there are 3 total discontinuities.

<u>A and B can be eliminated</u>

Since there is an (x+2) on the top and the bottom, they don't affect the shape of the function, but only causes a removable discontinuity when x = -2.

However, (x+6) and (x-3) are only on the bottom, so they DO change the shape, so they are non-removable

The answer therefore is 1 removable and 2 non-removable; D
