Answer:
D
Step-by-step explanation:
The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)
Step-by-step explanation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size
- If the equation of a line is ax + by = k is dilated, with center origin and scale factor k, then the equation of the image of the line is kax + kby = kc
- The line and its image are parallel
- The coordinates of a general point on the image is (kx , ky)
Line L is mapped onto the line T by a dilation centered at the origin and a scale factor of 3.
That means lint T is the image of line L after dilation
∵ The equation of line L is 2x - y = 7
∵ Line L is dilated by scale factor 3 and centered at origin
- That means multiply the equation of line L by 3 to find the
equation of line t
∵ Line T is the image of line L after dilation
∴ The equation of line T is (3)(2x) - (3)(y) = (3)(7)
∴ The equation of line T is 6x - 3y = 21
<em>Very important note:</em>
The equation of line T is the same with equation of line L but multiplied by the scale factor 3 ⇒ L and T are coincide lines (same line)
That means the equation of lines T and L is 2x - y = 7
The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)

Answer:
Choose the correct answer from your choices.
Step-by-step explanation:
First, we find the price of the turkey by multiplying the weight of turkey by the price per pound.
2.1 pounds of turkey at the deli. The price of the turkey was 2.87 per pound.
2.1 lb * 2.87 $/lb = $6.03
Then, we find the price of the ham by multiplying the weight of ham by the price per pound.
She also bought 4.8 pounds of ham. The price of the ham was 2.11 per pound.
4.8 lb * 2.11 $/lb = $10.13
Now we add the two prices together.
$6.03 + $10.13 = $16.16
The total price was $16.16
Answer:
b x 5 = 30
Step-by-step explanation:
This is one of the many correct answers. The reason why is because it shows that the variable is correct. And if you didn’t know what the variable was you could just divide 30 / 5.
