jane says that she can use addition to show that the graph of 2x-3y=1 and 2x+3y=2 are intersecting lines.In two or more complete sentences, describe the process of using addition to show that the lines are intersecting
Solution 1
+2x+3y=2
4x=3 substitute 3/4 for x in the first equation..you get y=2/9.
x=3/4
Solution 2
Answer:
Step-by-step explanation:
Two lines in a plane can intersect, overlap, or be parallel. When two lines intersect they have a common point which lies on both lines. when graphed represent straight lines. Adding the two equations uses the Elimination method to solve for x and y. The x and y value obtained is the common point lying on both lines.

Then Subtract the greater answer from the smaller one.
so 4 ft=1,2192
but 1,4 deeper than 4ft
Step 1: Simplify both sides of the equation.
1.5(x+4)−3=4.5(x−2)
(1.5)(x)+(1.5)(4)+−3=(4.5)(x)+(4.5)(−2)(Distribute)
1.5x+6+−3=4.5x+−9
(1.5x)+(6+−3)=4.5x−9(Combine Like Terms)
1.5x+3=4.5x−9
Step 2: Subtract 4.5x from both sides.
1.5x+3−4.5x=4.5x−9−4.5x
−3x+3=−9
Step 3: Subtract 3 from both sides.
−3x+3−3=−9−3
−3x=−12
Step 4: Divide both sides by -3.
−3x−3=−12−3
x=4

The required value of x in the equation is 3.43.
Given that,
Equation is, 1.5(x + 4) – 3 = 4.5(x – 2)
We need to find,
The value of x in the equation.
According to the question,
Equation = 1.5(x + 4) – 3 = 4.5(x – 2)
Simplify the equation, to determine the value of x
The value to x is 3.42.
Hence, The required value of x in the equation is 3.43.

The better buy is 16 ounces of the same brand for 3.68.
Given that
20 ounces of cereal for 4.40 or 16 ounces of the same brand for 3.68.
We have to determine
Which is the better buy?
According to the question
The amount of cereal for 20 ounces is 4.40.
Then
The cost per cereal is,
The cost per cereal is 4.45.
And the amount of cereal for 16 ounces is 3.68.
Then
The cost per cereal is,
The cost per cereal is 4.34.
Hence, the better buy is 16 ounces of the same brand for 3.68.

$6.72 for 4 sandwiches is $1.68 for each sandwich.
6.72/4=1.68
Obviously, go for the three sandwiches!
where a and b are the legs and c is the hypotenuse
so a = 6 and c = 8
lets solve for b
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 64 - 36
b^2 = 28
b = sqrt(28)
b = 5.29
b = 5.3 yards
Answer:
It's 5.3 yd, hope this helps
Step-by-step explanation:
The number would be - 8
lets do the work:
(8 x 4) - 6 = 26
Therefore your answer is 8.
Hope this helps!
