believe the answer is 8 because sulfur has 6 valence electrons and when it becomes sulfide it gains two electrons making it 6+2=8.

I need help with this, please. Your family is driving from Harrisburg Pennsylvania to San Antonio, Texas a trip of 1430 miles. Y
olga_2 [115]

Estimate the total amount you should plan to spend on gasoline for the entire trip

<em>Total distance of the trip</em> = 1430 miles

<em>After 350 miles, refill tank</em> = $35

This means 350 miles cost $35

1430 miles cost $x

solve using ratio

350 : 35 = 1430 : x

350/35 = 1430 / x

10 = 1430/x

<em>cross product</em>

10x = 1430

<em>Divide both sides by 10</em>

x = 1430 / 10

x = $143

Therefore, the total amount you should plan to spend on gasoline for the entire trip is $143

If f(x)=4x-2 and g(x)=-8x+7, find h(x)=f(x) - g(x)
user100 [1]

Answer:

h(x)=12x-9

Step-by-step explanation:

We are given the two functions:

f(x)=4x-2\text{ and } g(x)=-8x+7

And we want to find:

h(x)=f(x)-g(x)

So, by substitution:

h(x)=(4x-2)-(-8x+7)

Simplify. Distribute:

h(x)=(4x-2)+(8x-7)

Rearrange:

h(x)=(4x+8x)+(-2-7)

Combine like terms. Hence:

h(x)=12x-9

Find the equation of a line that passes through the given point<br>(-3,-4) and (2,11)
valentina_108 [34]

Answer:

y = 3x + 5

Step-by-step explanation:

The slope of this line is (11 - (-4)) /  (2 - (-3))

= 15/5 = 3

Now we use the point slope form of an equation:-

y - y1 = m(x - x1)

y - 11 = 3(x - 2)

y - 11 = 3x - 6

y = 3x + 5  (answer)
