I think it’s 3 because of y=mx+b so the right answer would be 3

Answer:

3.

Step-by-step explanation:

If Andre's representation is correct, that the slope is 3. The question is confusing me a bit, because it isn't very clear, but Andre's Representation is in Point Slope Form, (y=mx+b) where m represents the slope. So again, if Andre's representation is for the graph and is correct, the slope is 3.

In a pen of goats and chickens, there are 40 heads. and 130 feet How many goats and chickens are there?

timama [110]

Answer:

25 goat and 15 chicken

Step-by-step explanation:

Say the number of goats is G, then the number of chickens is 40 - G as there are 40 heads and each chicken and each goat has one head.

The number of feet is 130

So 2(40 - G) + 4G = 130

So 80 - 2G + 4G = 130

2G = 50

G = 25

icang [17]

Answer:

2/5 of a mile

Step-by-step explanation:

The easiest approach is to realise that one hour is 3 times longer than

20 minutes. The longer the time, the more they will pave.

2/5 of a mile, in 20 minutes, how much in 60 minutes?(#)

They will pave 3 times more.

2/15 x 3/1 = 6/15 of a mile

6/15 = 2/5 of a mile

Answer:

-1 and -3

(n+7)(n-8)

Step-by-step explanation:

1. Find the Zeros

$f(x)=x^{2} +4x+3$

$f(x)=\left(x+1\right)\left(x+3\right)$

$x+1=0\\x=-1\\x+3=0\\x=-3$

2. Factoring Trinomials

$f(x)=n^{2} -n-56$

$f(x)=\left(n+7\right)\left(n-8\right)$

$n+7=0\\n=-7\\n-8=0\\n=8$
