2x+y=7 for y neeedd help
Answers
Answer:
- y = -2x + 7
Step-by-step explanation:
Solve for y:
- 2x + y = 7
Add - 2x to both sides
- 2x + y - 2x = 7 - 2x
- y = 7 - 2x
or
- y = -2x + 7

Answer:
(7, 3)
Step-by-step explanation:
Given segment AB, where:
- A = (-1, -1)
Mid point
- M = (3, 1)
- Point B = (x, y)
As per mid point formula:
- (-1+x)/2 = 3 ⇒ -1 + x = 6 ⇒ x = 6+ 1 = 7
- (-1 + y)/2 = 1 ⇒ -1 + y = 2 ⇒ y = 2 + 1 = 3
So, the point B is:
- B = (7, 3)

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
First, subtract the numbers in the parentheses, then multiply by 11.
(12 - 9) = (3)
3 x 11 = 33
19 + 11 - 12^2 ÷ 3(33) - 7
Now, just multiply 33 by 3, and then square 12 (12 x 12).
19 + 11 - 144 ÷ 99 - 7
Now, you can divide 144 by 99, this is an infinite number, so..
144 ÷ 99 = 1.455
19 + 11 - 1.455 - 7
Finally add, then subtract.
30 - 1.455 - 7
28.545 - 7
The final answer is 21.545.

Answer:
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n
Step-by-step explanation:
8 cos^2 x + 4 cos x-4 = 0
Divide by 4
2 cos^2 x + cos x-1 = 0
Let u = cos x
2 u^2 +u -1 =0
Factor
(2u -1) ( u+1) = 0
Using the zero product property
2u-1 =0 u+1 =0
u = 1/2 u = -1
Substitute cosx for u
cos x = 1/2 cos x = -1
Take the inverse cos on each side
cos ^-1(cos x) = cos ^-1(1/2) cos ^-1( cos x) =cos ^-1( -1)
x = pi/2 + 2 pi n x = pi + 2 pi n where n is an integer
x = 5pi /3 + 2 pi n

Answer:
Step-by-step explanation:
a/(5h+q) = t
multiply both sides by 5h + q
a / (5h + q) * (5h+q) = t * (5h + q)
a = t * (5h + q)
I would say this is your answer.
You could distribute the t
a = 5ht + tq
which could also be an answer.

Length of the wall on blueprint will be 16 inches.
Use of scale to calculate the distances or length,
Scale used by an architect on a blueprint,
Scale represents the ratio of the length of the wall on blueprint and actual length,
If actual length of the east wall of the building = 24 feet
Substitute the value in the expression representing the ratio,
Length of the blueprint =
= inches
Therefore, length of the wall on blueprint will be 16 inches.

Answer:
16 in.
Step-by-step explanation:
We have the ratio
How about let's make this easier. Easier is better, right? Let's get rid of the fraction 2/3. We will do that by multiplying 2/3 by 3 and 1 by 3 to get the equivalent ratio of
Now we need to know how many inches there would be if the number of feet is 24:
Cross multiply to get
3x = 48 so
x = 16 in.
