**Answer 1**

**Answer:**

B is the Answer.

**Step-by-step explanation:**

A transformation of a function can be represented by

[tex]a(bx - h) + k[/tex]

where a is the vertical stretch or compression, b is the horizontal stretch or compression. H is the shift horizontally and k is the shift vertically.

The new function has a 2 instead of 1 on the orginally function. The function will stretch since 2 is greater than 1.

B is the answer.

### Answers

**Answer:**

A.) 6.4 units

**Step-by-step explanation:**

We can use the Pythagorean theorem to find the length of AB.

If we find the horizontal and vertical distance of A and B, we form a triangle, with leg lengths of 5 and 4.

Now, we just solve using the Pythagorean theorem.

5^2 = 25

4^2 = 16

25 + 16 = 41

sqrt 41 ≈ **6.4 units**.

find x, plzz helpp only have an hour to do this

### Answers

**Answer:**

E. None of these

**Step-by-step explanation:**

Using the **angle 43**, we see that we will **use Cos to find x**.

This is because the sides are the** adjacent and the hypotenuse**

**Cos (43) = 14/x**

**Multiply both sides by x**

X (cos (43)) = 14

**Then divide both sides by (cos(43))**

x = 14 / cos(43)

**Plug it into the calculator you get:**

**x = 25.22**

Since this is not an answer choice, the answer is **E. None of these**

Are shape I and shape II similar? If so, give the dilation that proves they are similar. If not, explain why the shapes are not similar.

### Answers

**Answer:**

The answer is "**They are similar**".

**Step-by-step explanation:**

They were comparable in this respect because both aspect ratios of the top triangle are one square more. The top triangle is equal to the base triangles if you remove one square away from the height and width.

Otherwise, we can say that it forms all different. The dilation factor which translates that bottom left point of shape I to form II is 2. But this does not map the other shape I vertices onto form II. There's, therefore, no dilation in form I of maps on form II.

3x - 4y = 17

+ ------------------

8x = 24

8 8

x = 3

Step 2.

a car can complete a journey of 300 km with a speed of 60 km per hour I) how much does it take the to complete the journey and what is the speed of the car if it covers only 200 km in the same interval of time

### Answers

**Step-by-step explanation:**

First step:

Distance = 300km

Speed = 60km/hr

We know,

Using Speed = Distance ÷ Time

Time = Distance ÷ Speed

we have Total Time = 300÷60

Total Time = 5hr

Again,

Distance = 200km. (Time = 5hr,

Speed =? Distance = 200)

Speed = Distance÷ Time

= 200÷5

= 40km/hr

Okay bro who gave you this question. I attempted to do this and I assumed it was a right triangle. That means a^2 + b^2 = c^2:

I plugged this into symbolabs and got a positive value for x to be [tex]\frac{2\sqrt{103}-15}{11}[/tex] which is approx 0.482. It does work when you plug it back in but that means x-5 < 0 which isn't possible. So unless you wrote something down wrong, this question technically doesn't make any logical sense.

Hello, stuck on 1 problem:

4/8 - 3/4 = ?

### Answers

**Answer:**

-2/8

**Step-by-step explanation:**

All you need to do is to find the common denominator which is 8

so 4/8 is good to go and remains as it is

For 3/4 you have to multiply the fraction by 2, both numerator and denominator

you will get 6/8

so 4/8-6/8 would give you -2/8 or -1/4

prove that √2 + √3 is irrational

### Answers

**Step-by-step explanation:**

Let √2 + √3 be a / b.

a and b are co - primes.

a and b have 1 as a common factor.

√2 + √3 = a / b

( √2 + √3 )^2 = ( a / b )^2

(√2)^2 + (√3)^2 + 2.√2.√3 = a^2 / b^2

2 + 3 + 2.√2.√3 = a^2 / b^2

5 + 2.√2.√3 = a^2 / b^2

2.√2.√3 = ( a^2 / b^2 ) - 5

2.√2.√3 = ( a^2 - 5b^2 ) / b^2

√2.√3 = ( a^2 - 5b^2 ) / 2b^2

a and b are not co - primes, as they more than 1 as a common factor.

So,

√2 + √3 is irrational.

Hence, proved.
