What is the rate of change of the linear relationship modeled in the table? (4 points) x y −2 5 −1 4 0 3 1 2 a −2 b −1 c negativ

Ostrovityanka [42]

Answer:

rate of change=slope= y2-y1/x2-x1

Step-by-step explanation:

x: -2|-1|0|1

y : 5|4|3|2

so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)

now we plug them in: $\frac{4-5}{-1-(-2)}$

4-5=-1

-1-(-2)=1

so -1/1 is equal to -1, meaning it's answer option b.

Which number line represtents the solution to |x+4|=2?

vlada-n [284]

Answer:

Points -2 and -6 on the number line are the two solutions.

Step-by-step explanation:

Use the definition of absolute value as a starting point

$|x|=x\,\,\mbox{for}\,\,x\geq 0\\|x|=-x\,\,\mbox{for}\,\,x$

To solve the equation, you need to treat the two cases as above:

$|x+4|=x+4=2\,\,\,\mbox{for}\,\,x+4\geq 0\implies x\geq -4\\x+4=2\implies x=-2$

The solution x=-2 is consistent with the condition x>=-4, so it is the first and valid solution. Now the second case of the absolute value:

$|x+4|=-(x+4)=2\,\,\,\mbox{for}\,\,x+4< 0\implies x$

Again, the second solution -6 complies with the requirement that x<-4, so it is valid.

If a dozen eggs cost $1.35,what is the unit cost?

Lemur [1.5K]

Answer:

The cost of an egg is $0.11

Step-by-step explanation:

Given : The cost of one dozen of eggs is $ 1.35

We have to find the cost of one egg.

We know, one dozen has 12 units

Thus, One dozen of eggs contain 12 eggs

So cost of 12 eggs is $ 1.35

So to find the cost of one egg divide the cost by 12.

We get,

1 egg = $\frac{1.35}{12}=0.1125$

Thus, The cost of an egg is $0.11
