Please further explain your question...
You have to find the greatest common factor GCF for each number, you can do it for both at the same time:
foot ---- hand
GCF 48 60
2 24 30
2 12 15
3 4 5
From here you dont have more numbers (GCF) for this pair, now for finding the greatest number of identical kits multiply the GCFs: 2*2*3=12 you have 12 kits containing 4 foot-warmer packets and 5 hand-warmer packets (from table the last row in foot and hand)
Equation of the line is 3x + y + 4 = 0
Step-by-step explanation:
- Step 1: Given points are (1, -7) and (-4,8)
⇒ x1 = 1, x2 = -4, y1 = -7, y2 = 8
- Step 2: Form equation for the line using (y-y1) = m(x-x1). Find slope m.
⇒ m = (y2 - y1)/(x2-x1) = (8 - -7)/(-4 - 1) = 15/-5 = -3
- Step 3: Substitute the values and form the equation.
⇒ y - -7 = -3(x - 1)
⇒ y + 7 = -3x + 3
⇒ 3x + y + 4 = 0
Answer:
B
Step-by-step explanation:
In the answer choice B, the " is the same as" can be used to denote an equal sign, and can therefore be written as an equation because an equation requires an equal sign.
