Answer:

L’M’ = 4.5 units

Step-by-step explanation:

We start by getting the dilated coordinates

we specifically work with the points LM

The dilated points can be obtained by multiplying the individual coordinates by 1.5

for L (1.5 * -4 and 1.5 * -3) = L’ (-6, -4.5)

M (-4,0) and ; (1.5 * -4 and 0 * 1.5) = M’ (-6,0)

Now, we can use the distance formula

D = √(y2-y1)^2 + (x2-x1)^2

D = √(0+ 4.5)^2 + (-6+6)^2

D = √(4.5)^2

D = 4.5 units

Answer:

7x° + 11x° = 90°

(Required equation)

Step-by-step explanation:

7x° + 11x° = 90°

(complementary angles)

18x° = 90°

18x = 90

x = 90/18

x = 5

Answer:

As time goes by the virus expands, and evolves causing more people to get infected. Although people who have made it before when the virus had affected them do not get affected by the evolved virus. People who have weak immune systems when infected die. Therefore, the reason thatthe deaths and recoveries happen to rappidly is because of the virus evolving, when some people are able to withstand it whilst others die.

Hope this helped.

Answer:

234.784 ~ 235

Step-by-step explanation:

One side = 210

other side = 105

a2+b2 = c2

210 ^2 + 105 ^2 = c2

55125 = c ^2

c = [tex]\sqrt{55125}[/tex] = 234.784 ~ 235

hope its right!!!

Answer:

D) a 13% decrease in value each year

Step-by-step explanation:

Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.

What does 0.13 represent?

The expression given above represents and expression of exponential decrease.

This is represented by the formula

y = a(1 - r)^t

Where

y = Value after time t

a = Initial value

r = Rate of decrease

t = Time

Comparing both expressions

y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t

We can see that:

r = 0.13

This is the rate of decrease.

Converting to Percentage = 0.13 × 100

= 13%

Option D is the correct option.

Answer:

When you reflect a point across the X-axis, the X-axis coordinate remians the same, but it's opposite ( It's sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the X-axis (The line of reflection) to see where the new figure will be located

Answer:

5/4

Step-by-step explanation:

7.5/6=1.25

15/12=1.25

10/8=1.25

1.25 is basically 5/4 in a fraction

So 5/4

Rememeber that the Scale factor is the ratio of correspondind sides

Answer:

a) 4c+3b=11.67

   8c+b=12.89

b)One loaf of bread cost $2.09

  One can of soup costs $1.35

Step-by-step explanation:

Let c= can of soups    Let b= loaf of bread

a) To find the equation, you know that Khalil buys four cans of soup and 3 loafs of bread and 4 cans of soup for $11.67 so that means that the first equation will be 4c+3b=11.67. Then, you know that Khalil buys 8 cans of soup and one bread for $12.89. so the next equation will be 8c+b=12.89. This means the system of linear equations will be

4c+3b=11.67

8c+b=12.89

b) Use elimination to solve this. You want to make one variable from each equation the same so multiply 4c+3b=11.67 by 2. This will look like 2(4c+3b=11.67). Then simplify to get 8c+6b=23.34 and 8c+b=12.89. Because 8 and 8 are the same, you have to subtract the equations from each other making 5b=10.45. Simplify that and you get b= 2.09 so the one loaf of bread cost $2.09. Then  plug 2.09 into 8c+b=12.89. It will look like this 8c+2.09=12.89. Simplify that and you get 8c=10.8. Simplify that again and you will get 1.35 so a can of soup will costs $1.35

Therefore

a) 4c+3b=11.67

   8c+b=12.89

b) One loaf of bread cost $2.09

   One can of soup costs $1.35

Answer:

C

Step-by-step explanation:

Using Pemdas:

3 (1 + 4) / 3 + 4^2

3 (5) / 3 + 4^2

3 (5) / 3 + 16

15 / 3 + 16

Answer:

A

Step-by-step explanation:

First you have to simplify the equation, you should use PEMDAS. This means you first have to simplify the parenthesis.  simplify it, multiply 3 by 1 and 4. This makes the equation 3+12/3+4^2. Then following PEMDAS, you simplify the exponent. 4^2 is the same as 4x4 so 4^2 is 16. 3+12/3+16, then you can simplify either side first. 3+12/18, then you simplify the only part left. 15/18. The GCM of this fraction is 3 so you divide both sides by 3. 15/3/18/3. Simplify this to get 5/6.

When you simplify equation A, you get 15/3/6. First simplify 15/3 to get 5. This equation answer is 5/6 which is equal to 5/6 so this is the correct answer.

When you simplify equation B, you get 15/3/8. Simplify 15/3 again and get 5. This equation answer is 5/8 which is not equal to 5/6 so this is not the correct answer.

When you simplify equation C, you get 15/3/16. Simplify 15/3 first and get 5. 5/16 is not equal to 5/6 so this is not the correct answer.

Therefore, Equation A is the correct answer.

Answer:

I cant see your problome I dont know why but what is it

Step-by-step explanation:

Answer:

Question 1: g = 6

Question 2: v = 84

Question 3: y = 60

Question 4: w = 496

Question 5: Kyle had $400 to begin with.

Step-by-step explanation:

Question 1 explanation: 12g = 72 ⇒ g = [tex]\frac{72}{12}[/tex] = 6

Question 2 explanation: [tex]\frac{v}{4}[/tex] = 21 ⇒ v = 21 * 4 = 84

Question 3 explanation: [tex]\frac{1}{6}[/tex] y = 10 ⇒ 6 * [tex]\frac{1}{6}[/tex] y = 10 * 6 ⇒ y = 60

Question 4 explanation: w + 376 = 872 ⇒ w = 872 - 376 = 496

Question 5 explanation: K - 85 = 315 ⇒ K = 315 + 85 = 400, so Kyle had $400 originally in his account.
