Answer:

The correct answer would be 8x - 12.

Step-by-step explanation:

2 ( -6 + 4z)

= (2) ( -6 + 4z)

= (2) ( -6) + (2) (4z)

= 12 + 8z

= 8z - 12

Hope this helps!

Answer:

Expanded answer: 8z - 12

OR

Factored answer: 4(2z - 3)

Step-by-step explanation:

Solve using the <u>distributive property</u>. This is when you multiply the number outside the brackets by each number inside the brackets.

2(-6 + 4z)

= (-6)(2) + (4z)(2)        Multiply each number by 2

= -12 + 8z        When you can, try not to start with a negative number.

= 8z - 12        This is the answer in <u>expanded form</u>

Refactored:

"8z" and "12" have a GCF (greatest common factor) of 4. Take out "4" from the expression to factor.

8z - 12

= 4( 8z/4 - 12/4 )        Divide each term by 4.

= 4(2z - 3)         This expression is equivalent when you need it <u>fully factored</u>.

3. Write an equation in point-slope form for the line through the given point with the given slope.
jok3333 [9.3K]

Answer:

B

Step-by-step explanation:

recall that point-slope form of a linear equation is expressed as follows

y - y1 = m (x - x1)

where m = slope and (x1, y1) is the coordinate of any point on the line

so, here we have m = (3/5), x1 = 4 and y1 = -6

substitute these into the formula

y - (-6) = (3/5) (x - 4)

y + 6 = (3/5) (x - 4)----> answer

Three equivalent ratios for 6: 54
vodka [1.7K]
Treat it as a fraction where it must stay equal
6/54
with fractions, you can do anything as long as you do it so top and bottom
so 6/54=1/9=2/18=3/27=4/36=5/45 etc

but don't forget to convert back to ratios
so some examples are 1:9
2:18
3:27
4:35
5:45

What is the equation of the line (-2,-3) (4,5)
sleet_krkn [62]
Slope = m = y2-y1/x2-x1
 = 5-(-3)/4-(-2)
m=8/6
m=4/3
so  eq of line we select any of one point . i select (4,5)
y - y1 = m(x-x1)
y- 5 = 4/3 (x-4)
3y -15 = 4x-16
4x-3y = 1

Therefore the amount of gas that would be left after 6 hours can be calculated as follows

= 13-6

= 7

Hence there will be 7 gallons of fuel left
