How do u show that these 2 lines are parallel
L is y=3x-2
L*2 is 3y-9x+5=0
Answers
Answer:
If two lines are parallel, then they have the same gradient.
Step-by-step explanation:
L is y=3x-2
L*2 is 3y-9x+5=0
The gradient for the first equation is 3
We need to rearrange the second equation and see if it has the same gradient as the first equation.
L*2 is 3y-9x+5=0
3y = 9x - 5
L*2 y = 3x - 5/3
As you can see, once you rearrange and simplify the equation, the second line has the same gradient as the first equation.
So that means these two lines are parallel

If A=1/2 h (b1 +b2) is the formula for the area of a trapezoid, find the height of the trapezoid that has an area of 78 in ^2 and base lengths 5 in and 8 in.
Answers
Answer:
A is the answer
12 in
first substitute the variables
then 78=1/2h(5 + 8)
this makes it an equation
add similar terms which equals to
78=1/2xhx13
then divide both sides by 13
6=1/2xh
lastly divide both sides by 1/2
12=h
Step-by-step explanation:
proof
A=1/2x12(5 + 8) then
A=1/2x12x13 then
A=6x13 then
A= 78in^2

Billy and Tommy went to the movies. They are going to combine their money for snacks. Popcorn costs $8 and a box of candy costs $1.50 each. They each want their own popcorn. They spent the rest of the money on candy. If the total cost was $25.00, how many boxes of candy did they buy? Create a algebraic equation and solve for the number of candy boxes.
Answers
Answer:
6 candy boxes
Step-by-step explanation:
Since they both bought their own popcorn that means they both spent $8 on popcorn making that a total of $16. Therefore we now only need to find one variable which is the number of candy boxes that they bought in order to reach the $25 total that they spent. This variable can be represented as x in the following algebraic equation.
(2*8) + 1.50x = 25
16 + 1.50x = 25 ... subtract 16 from both sides
1.50x = 9 ... divide both sides by 1.50
x = 6
Finally, we can see that Billy and Tommy bought a total of 6 candy boxes.
What should be the first step to solve the equation? 2x + 9(x - 1) = 8(2x + 2) - 5

Subtract 4 on both sides
2x=14
Divide 2 on both sides
X=7
Answer:
x = 7
Step-by-step explanation:
3x - (x - 4) = 18 =
3x - x + 4 = 18 =
2x + 4 = 18 =
2x + 4 - 4 = 18 - 4
2x = 14
x = 7
