Answer: x = 4 , y = 6
Step-by-step explanation:
4 x = 3 y − 2 , 18 = 3 x + y
Solve for y
in the second equation.
Tap for more steps...
4 x = 3 y − 2 y = 18 − 3 x
Replace all occurrences of
y in 4 x = 3 y − 2
with
18 − 3 x . 4 x = 3 ( 18 − 3 x ) − 2 y = 18 − 3 x
Simplify
3 ( 18 − 3 x ) − 2
Tap for more steps...
4 x = − 9 x+ 52 y = 18 − 3 x
Move all terms in
4 x = − 9 x + 52
to the left side and simplify.
Tap for more steps...
13 x − 52 = 0 y = 18 − 3 x
Solve for x
in the first equation.
Tap for more steps...
x = 4 y = 18 − 3 x
Replace all occurrences of
x in y = 18 − 3 x
with 4 . x = 4 y = 18 − 3 ⋅ 4
Simplify
18− 3 ⋅ 4
Tap for more steps...
x = 4 y = 6

4x=3y-2 in slope intercept form
Explain
Answer:
y = 1-1/3x + 2/3
Step-by-step explanation:
Slope-intercept form is y=mx+b
Subtract 3y from both sides to move it to the left side. You now have:
-3y + 4x = -2
Subtract 4x from both sides to move it to the right side. You now have:
-3y = -4x -2
Divide by -3 to get y alone:
y = 1-1/3x + 2/3
Two of the lowest temperatures ever recorded in the U.S. are -79.8 *F in Alaska and -69.7*F in Montana. Write an inequality that compares the temperatures.
Answer:
During cool or cold weather episodes, fuel must be consumed to make buildings comfortable living spaces. A useful indicator of fuel consumption for heating purposes is the determination of heating degree-days. They are calculated by accumulating one heating degree-day (HDD) unit for each Fahrenheit degree the daily mean (average) temperature is below the base value of 65°F (18°C). For example, a day with a maximum temperature of 60°F and a minimum of 40°F has a mean temperature of 50°F. Subtracting 50 from 65 yields 15 heating degree-day units for that day. Hence, a day with a high temperature of 45°F and a low of 25°F produces ______ HDDs.

A machine packs boxes at a constant rate of 2/3 of a box every 1/2 minute. What is the number of boxes per minute that the machine packs?
A 1/3
B 3/4
C 1 1/6
D 1 1/3
Answer:
I would say C. 1 1/6
Step-by-step explanation:
Answer: D (1 1/3
Step-by-step explanation:
if it’s 2/3 every half a minute then you do 2/3 times two, or you can just add two onto the numerator. that would give you 4/3 which simplifies to 1 1/3
Prove that the median to the base of an isosceles triangle is also: the altitude to the base.
Also, Prove that the median to the base of an isosceles triangle is also: the angle bisector of the angle from which it is drawn.
Please provide statement and reason proof. Would really appreciate it. Best Answer will get brainliest, and please don't spam stuff just for points. Thanks, and have a great day!
Hey there!
The base angles theorem converse states if two angles in a triangle are congruent, then the sides opposite those angles are also congruent. The Isosceles Triangle Theorem states that the perpendicular bisector of the base of an isosceles triangle is also the angle bisector of the vertex angle.
Let me know if you are still confused and need a better explination :)

Write a polynomial in standard form that represents the area of the shaded region.
A rectangle. Its length is labeled 2 x minus 9 and its width is labeled x plus 5.
Answer:
2x²+x-45
Step-by-step explanation:
In standard form the area of the rectangle is -
A = (2x² + x - 45) square units.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is to write a polynomial in standard form that represents the area of the shaded region which is rectangle whose length is labeled (2x - 9) and its width is labeled (x + 5).
We can write the area of the rectangle as -
A = (2x - 9)(x + 5)
A = 2x(x + 5) - 9(x + 5)
A = 2x² + 10x - 9x - 45
A = 2x² + x - 45
Therefore, in standard form the area of the rectangle is -
A = (2x² + x - 45) square units.

Help.......?!!?!/1?!
Answer:
I think 157 pavers
Step-by-step explanation:
I may be able to help with number 10, if the trees are to be decorated with a ring of decorative pavers then we have to find the circumference, if the radius is 5 then using the circumference formula, 2×3.14(pi)×the radius, you'll get 31.4 and since there is 5 trees to be decorated then multiply 31.4 times 5 which will give you 157 feet of pavers to surround all five trees. I apologize if it is incorrect.

A perimeter is a sum of lengths of sides of a lateral.
Directions: Answer the following questions, showing all pertinent work. Paul has a 40 ft. by 30 ft. pole barn on his farm that he wants to move. The southeast corner of the pole barn is currently located 50 ft. west and 25 ft. north of the stock tank where the cows get their water. Paul wants to move the pole barn so the southeast corner of the barn is located 80 feet east and 80 feet south of the stock tank. 1. Complete the transformation statement for moving Paul’s pole barn. (x, y)→(x + _______ , y + _______ ) —continue to the next page—
Answer: (x + 130, y - 55)
Step-by-step explanation: If the southeast corner of the pole barn is the only reference point, it only requires this one point and not the size of the barn.
Let's set this up first: West/South= Negative x/y, and East/North= Positive x/y.
Currently, the corner is at -50, 25. The corner needs to be moved to 80, -80.
For x: |-50|+80=130
For y: |25|+(-80)=-55
The formula for this is |a|+b=c.
This leaves it with (x + 130, y - 55)
