Answer:
he number 7 is a prime number because it can't be divided by any other other number
Step-by-step explanation:
Answer:
13. y = -4x + 6
14. y = 1/2x - 2
Step-by-step explanation:
You want to put y on one side and the rest of the numbers on the other side. You can do this by adding or subtracting or dividing the numbers/variables on the left.
13.
4x + y = 6
subtract both sides by 4x
y = 6 - 4x
or rewritten as:
y = -4x + 6
14.
-3x + 6y = -12
add both sides by 3x
6y = 3x - 12
divide both sides by 6
y = 1/2 x - 2

Answer:
A, D, and E
Step-by-step explanation:
The ratio between the sides of the rectangle is 12/3 = 4. In a scaled copy of rectangle A, the ratio between the sides needs to be 4 too.
For answer A the 6/1.5 = 4, has the same ratio therefore is a scaled version of rectangle A
For answer B the 10/2 = 5, it does not has the same ratio therefore is not a scaled version of rectangle A
For answer C the 13/4 = 3.25, it does not has the same ratio therefore is not a scaled version of rectangle A
For answer D the 18/4.5 = 4, has the same ratio therefore is a scaled version of rectangle A
For answer E the 80/20 = 4, has the same ratio therefore is a scaled version of rectangle A
