Answer: For the graph,

43. y=2.5x−4

45. y=−15x+3

47. y=12x+−94

Step-by-step explanation:

43.

Let's solve for x.

y=2.5x−4

Step 1: Flip the equation.

2.5x−4=y

Step 2: Add 4 to both sides.

2.5x−4+4=y+4

2.5x=y+4

Step 3: Divide both sides by 2.5.

2.5x2.5=y+42.5

x=0.4y+1.6

Answer:

x=0.4y+1.6

45.

Let's solve for x.

y+15x=3

Step 1: Add -y to both sides.

15x+y+−y=3+−y

15x=−y+3

Step 2: Divide both sides by 1/5.

15x15=−y+315

x=−5y+15

Answer:

x=−5y+15

47.

Let's solve for x.

2x−3=4y+6

Step 1: Add 3 to both sides.

2x−3+3=4y+6+3

2x=4y+9

Step 2: Divide both sides by 2.

2x2=4y+92

x=2y+92

Answer:

x=2y+92

If Q = {all perfect squares less than 30} and p={ all odd numbers from 1 to 10}
Soloha48 [4]

When Q = {all perfect squares less than 30} and p={ all odd numbers from 1 to 10) Q ∩ P = { 1, 9}

<h3>How to calculate the value?</h3>

Set theory simply means the branch of mathematical logic that deals with sets, that can be described as collections of objects.

It should be noted that perfect squares are the numbers that can be divided to give same number.

Q = {all perfect squares less than 30}. This will be 1, 4, 9, 16, 25

P ={ all odd numbers from 1 to 10}. This will be 1, 3, 5, 7, and 9.

In this case, the common numbers to set of P and Q are 1 and 9.

Therefore, the numbers are 1 and 9 since they're common to both sides.

Hi! Can someone help me with the following question?
valina [46]

Answer:

9√2

Step-by-step explanation:

√32 = √(16*2) = √(4²*2)=4√2

√200 = √(2*100) = √2*10²) = 10√2

3√50 = 3√(25*2) = 3√(5²*2) = 15√2

the original can then be rewritten as

4√2 - 10√2 + 15√2 = 9√2
