2x+3y=4 y+3x=6
find x and y
Answer:
x=-3/2y+2
y= y=−3x+6
Step-by-step explanation:
solve for x.
2x+3y=4
Add -3y to both sides.
2x+3y+−3y=4+−3y
2x=−3y+4
Divide both sides by 2.
2x/2= -3+4/2
x= -3/2 y+2
solve for y.
y+3x=6
Add -3x to both sides.
3x+y+−3x=6+−3x
y=−3x+6

A window in the room has an actual width of
2.5 feet.
Find the width of the window in the blueprint.
The width of the window in the blueprint is

The width of the window in the blueprint will be 2.7 inch.
What is the equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
From the given table choose;
⇒ (x₁ , y₁ ) = (3, 5) & (x₂, y₂ ) = (3, 5)
Since, We know that equation of line is,
⇒ y – y₁ = ((y₂ – y₁)/(x₂ – x₁ )) (x – x₁)
⇒ (y - 3) = ((10-5)/(6-3))(x - 3)
⇒ 3(y - 3) = 5(x - 3)
⇒ 3y = 5x -15+9
⇒ 5x- 3y = 6 ….(i)
This is the required equation.
Given that; the length of wall on blue print = 10 inch
Then, put x = 10 in equation (i) we get;
⇒ 5x10 – 3y = 6
⇒ -3y = 6 - 50
⇒ y = 14.6 ft
The actual length be = 14.6 ft
And, Also given that actual width of window = 2.5 feet
Then put y = 2.5 in equation (i) we get
⇒ 5x – 7.5 = 6
⇒ 5x = 13.5
⇒ x = 2.7 inch
Thus, The width of the window in the blueprint is 2.7 inch.

If the points are (-10, 3), (-2, 10) what is the slope?
Answer:
= 7/ 8
Step-by-step explanation:
We can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 10-3)/( -2 - -10)
= ( 10-3)/( -2 +10)
= 7/ 8
An airplane begins decreasing its altitude as it approaches the runway. At time t=1, the pilot notes that he has an altitude of 30,000 feet. One minute later, his altitude drops to 29,450 feet. One minute after that, his altitude drops to 28,900 feet. Assuming this pattern continues, write a recursive formula for the altitude of the plane A(t) after t minutes.(1 point)
A(t)=30000+550(t−1)
A(t)=A(t−1)−550 for t>1, where A(1)=30000
A(t)=A(t−1)+550 for t>1, where A(1)=30000
A(t)=30000−550(t−1)
Answer: i think A(t)=30000−550(t−1)

In this case, we need to substitute n with 10.
So, it is like this: f(10) = 3(10) + 4
f(10) = 3(10) + 4
f(10) = 30 + 4
f(10) = 34

Solve for the variable!! Please
Answer:
[tex]\huge\boxed{t=3}[/tex]
Step-by-step explanation:
[tex]-5(t+3)=-30[/tex]
METHOD 1:[tex]-5(t+3)=-30[/tex] divide both sides by (-5)
[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]
[tex]t+3=6[/tex] subtract 3 from both sides
[tex]t+3-3=6-3\\t=3[/tex]
METHOD 2:[tex]-5(t+3)=-30[/tex] use the distributive property a(b + c) = ab + ac
[tex](-5)(t)+(-5)(3)=-30[/tex]
[tex]-5t-15=-30[/tex] add 15 to both sides
[tex]-5t-15+15=-30+15[/tex]
[tex]-5t=-15[/tex] divide both sides by (-5)
[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

5/8 - 1/16= what’s the answer to this please help
Answer:
9/16
Step-by-step explanation:
(5/8 * 2/2) - (1/16 - 1/1)
10/16 - 1/16
10-1//16 = 9/16
5/8 - 1/16 = 9/16
(5*16) - (1*8) / 8 * 16
80-8/ 128
72/128
72/8
128/8= 9/16
5/8 - 1/16 = 9/16

Find the nth term of this quadratic sequence.
3, 11, 25, 45
Answer:
3 , 11, 25, 45
Diff 8 14 20
Diff 6 6
The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3
therefore 3n^2
3 11 25 45
3n^2 3 12 27 48
Remainder 0 -1 -2 -3
Difference -1 -1 -1
linear sequence with nth term -n+1
so nth term of quadratic sequence in 3n^2-n+1

Sinister Stan stole 3 3/4 oz of slime from Messy Molly, but his evil plans require 6 3/8 oz of slime. He stole another 2 3/5 oz of slime from Rude Ralph. How much more slime does Sinister Stan need for his evil plan?
Answer: 1/40
Step-by-step explanation:
Since we are told that Sinister Stan stole 3 3/4 oz of slime from Messy Molly and stole another 2 3/5 oz of slime from Rude Ralph. The total oz of slime stole would be:
= 3 3/4 + 2 3/5
= 3 15/20 + 2 12/20
= 5 27/20
= 6 7/20
We are told that his evil plans require 6 3/8 oz of slime, the amount needed for Sinister Stan for his evil plan would be:
= 6 3/8 - 6 7/20
= 6 30/80 - 6 28/80
= 2/80
= 1/40

The product of two numbers decreased by six is less than 30. Write an algebraic expression, but do not solve. *
Answer:
(x × y) - 6 < 30
xy - 6 < 30
xy < 30 + 6

Let us represent:
First number = x
Second number = y
The product of two numbers decreased by six is less than 30.
The algebraic expression is given as
(x × y) - 6 < 30
xy - 6 < 30
xy < 30 + 6
