Answer: The cost of 3 jackets= $69.75

Step-by-step explanation:

From the given table, we can see that

The cost of 2 jackets=$46.50

Thus, the cost of 1 jacket= $\frac{46.50}{2}=\$23.25$

To find the cost of 3 jackets, we need to multiply 3 to the the cost of 1 jacket, we get

The cost of 3 jackets= $3\times23.25=\$69.75$

Hence, the cost of 3 jackets= $69.75

Which of the following equations represents a line parallel to 4x - y = -5?

pickupchik [31]

Correct answers are A, C and D.

Parallel lines have equal slopes.

4x - y = -5 ⇒ y = 4x + 5 ⇒ m = 4
8x - 2y = -10 ⇒ 4x - y = -5 ⇒ m = 4
4x + y = -2 ⇒ y = -4x - 2 ⇒ m = -4
4x - y = 2 ⇒ y = 4x - 2 ⇒ m = 4
$2x - \frac{1}{2}y = -\frac{5}{2}\Rightarrow4x-y=-5 \Rightarrow y=4x+5 \Rightarrow m=4$
