Solve for x&y, y=3x-4 & y= 2x + 1
Please show step by step how you got the answer
Answers
Answer:
(5, 11 )
Step-by-step explanation:
Given the 2 equations
y = 3x - 4 → (1)
y = 2x + 1 → (2)
Substitute y = 3x - 4 into (2)
3x - 4 = 2x + 1 ( subtract 2x from both sides )
x - 4 = 1 ( add 4 to both sides )
x = 5
Substitute x = 5 into either of the 2 equationsfor corresponding value of y
Substituting into (2)
y = 2(5) + 1 = 10 + 1 = 11
solution is (5, 11 )
Answer:
This is a system. put the first equation under the second one and subtract. y - y = 0. 2x - 3x = -x. 1 - (-4) = 5. so the result is 0 = -x +5 or x = 5. plug x into either equation and y = 11. the answer is (5, 11).

It is possible to form a triangle with the given side lengths
What is a triangle?A triangle is a two-dimensional geometrical figure that has three sides, three vertices and three interior angles.
Given, three sides are 7 yards, 8 yards, 9 yards.
Let, three sides are 'a', 'b, 'c' and 'a' is the largest among these three.
Then, a triangle can be formed with these three sides if (b + c)>a.
Here, 9 yards is the largest.
Therefore, (7 + 8) yards = 15 yards > 9 yards
Therefore, with these three sides, a triangle can be formed.

How many triangles can be constructed with angles measuring 50º, 90º, and 40º?
Answers
Answer:
Infinite
Step-by-step explanation:
We know that in a triangle the sum of all the interior angles must be 180°.
The given angles 50º, 90º and 40º
The sum of the angles 50º+ 90º + 40º= 180°
Thus, a triangle is possible with the given measurement.,
Let there is another triangle with the given angles, then by AAA similarity criteria they are similar.
Similarly, all the triangles with the same measurements of the angles must be similar.
Therefore, there are infinite number of triangles can be possible with angles measuring 50º, 90º, and 40º.

what is the distance between points M(-3, 1)and N(7, -3)
Answers
Answer:
d = 2√29 units
Step-by-step explanation:
M(-3, 1)and N(7, -3)
To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Plug in the values.
d = √[(7 - (-3))² + (-3 - 1)²]
Simplify the parentheses.
d = √[(7 + 3)² + (-4)²]
d = √[(10)² + (-4)²]
Simplify the exponents
d = √[(100 + 16)]
Simplify the parentheses by adding.
d = √[116]
Simplify the brackets with the square root.
Since 116 is not a perfect square, we need to find two numbers that multiply to 116. One number must be a perfect square. The other must be a prime number.4 • 29 = 116. Therefore √4 • √29 = √116√4 = 2. Therefore 2√29 = √116d = 2√29 units

Area of rectangle is defined as the product of its length and width.
Let suppose two separate rectangles. Calculate area as length x width. Here’s that shows
1: 40x25 = 1000
2: 20x40 = 800
After that we calculate the square footage of each by adding them up to it’s sum.

Answer:
x = 3, y = 7
Step-by-step explanation:
Since we already have y's value, we can plug y into the bottom equation to get 3(5x - 8) = x + 18. We can distribute 3 into 5x and 8 to get 15x - 24 = x + 18. We can now subtract x from the both sides to get all terms on one side to get 14x - 24 = 18. We can now add 24 to both sides to get 42. We can now divide both sides of the equation by 14 to get x = 3. We can plug x into the top equation to get y = 5(3) - 8. We can multiply 5 and 3 together to get y = 15 - 8. We can simplify and subtract to get y = 7. Our final answer is (3, 7)
Cindy has a salary of $880 per week and is paid every two weeks.

Enter your answer as a number rounded to the nearest cent, such as: 150.12.
Answers
Answer:
244.80 If I'm not wrong.
Step-by-step explanation:
Add all of the deductions together and subtract them by 880
By using g00gle I found out that 195.82 + 63.60 + 134.64 + 176.00 = 635.24.
So now you subtract it by her salary down below:
880.00 - 635.24 = 244.76
244.80 or 245 if I'm not wrong
Cindy's net income on each paycheck will be $244.76.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given;
Federal income taxes: $195.82
State income taxes: $63.60
Insurance: $65.18
FICA: $134.64
Retirement plan: $176
Add all of the deductions together;
195.82 + 63.60 + 134.64 + 176.00 = 635.24.
So now we will subtract it by her salary down below:
880.00 - 635.24 = 244.76
Hence, Cindy's net income on each paycheck will be $244.76.

Jackie is buying crackers and wants to know how many crackers are in the box. The box is 8 cm long, 2.4 cm wide, and 60 cm high. The dimensions of the crackers are 3cm long, 4 cm wide, and 5 cm high. How many crackers are in the box? Round to the nearest whole number. Geometry
Answers
Answer:
19
Step-by-step explanation:
Number of crackers that can be fit into the box = volume of the box / volume of crackers
Volume = length x width x height
volume of the box = 8 cm x 2.4 cm x 60 cm = 1152 cm^3
Volume of the crackers = 3cm x 4 cm x 5cm = 60cm^3
1152/60 = 19.2
Rounding 19.2 to the nearest whole number gives 19
