find the ordered pair (x,y) that is a solution to the equation
x-4y=8
Answer:
(4,-1)
Step-by-step explanation:
x-4y=8
-4y=-x+8
y=1/4x-2
The solution to the equation x - 4y = 8 is an ordered pair (4,-1).
What is the solution to the equation?A solution to an equation is a number that can be substituted for the variable to provide a true number statement.
The equation is given in the question, as follows:
x - 4y = 8
To determine the ordered pair (x,y) of the solution, substitute the value of x = 4 in the equation, and solve for y:
4 - 4y = 8
- 4y = 8 - 4
- 4y = 4
y = - 4/4
Divided by -4 into both sides of the equation, we get
y = - 1
Thus, the solution to the equation is an ordered pair (4,-1).

Answer:
B. 77
Step-by-step explanation:
because (72 + 97 + 82 + 77) ÷ 4 = 82
Pls Brailniest! ;) It would mean a lot.
Answer:
77
Step-by-step explanation:
If you add all the numbers you would get 251 and if you divide that by 3 you get 83.67. So what I did to get a mean of 82 was add those 3 numbers then the individual answer choice. so 72+97+82+77=328. 328/4 is equal to 82

If a problem is y * 4 and equals 20, what is y equal too?
Answer:
5(I think)
Step-by-step explanation:
Yx4 =20
What (x) 4=20?
5x4=20
Answer:
y = 5
Step-by-step explanation:
set up an equation
y * 4 = 20
now solve using inverse operations
y * 4 = 20
/4 /4
y = 20 / 4
20 / 4 =5
because
4 * 5 = 20
y = 5

y = 1/2x + 3
y = 3x + 2
Answer:
the first one
Step-by-step explanation:
Answer:
y = 2x + 3
Step-by-step explanation:
because the y intercept is 3 based on the graph then i found two points (-4,1) and (-2,2) then i used solved. -4+2=-2 , 1-2 =-1 which means that you get -2/-1 which equals 2

5x - 29.4 + 1/2x when x is 11/5
Answer:
-17.3
Step-by-step explanation:
Evaluate 5 x + x/2 - 29.4 where x = 11/5:
5 x + x/2 - 29.4 = 5×11/5 - 29.4 + 1/2×11/5
Hint: | Express 5×11/5 as a single fraction.
5×11/5 = (5×11)/5:
(5×11)/5 - 29.4 + (11/5)/2
Hint: | Express (11/5)/2 as a single fraction.
(11/5)/2 = 11/(2×5):
(5×11)/5 - 29.4 + 11/(2×5)
Hint: | Cancel common terms in the numerator and denominator of (5×11)/5.
(5×11)/5 = 5/5×11 = 11:
11 - 29.4 + 11/(2×5)
Hint: | Multiply 2 and 5 together.
2×5 = 10:
11 - 29.4 + 11/10
Hint: | Approximate 11/10.
11/10≈1.1:
11 - 29.4 + 1.1
Hint: | Evaluate 11 + 1.1 using long addition.
| 1 | 1. | 0
+ | | 1. | 1
| 1 | 2. | 1:
12.1 - 29.4
Hint: | Factor out a negative sign in 12.1 - 29.4 in order to subtract.
12.1 - 29.4 = -(29.4 - 12.1):
-(29.4 - 12.1)
Hint: | Subtract 12.1` from 29.4`.

What is the area of the trapiziod
Answer:
950 feet
Step-by-step explanation:
the area of a triangle is a=(bh) 1/2
plug in the values for a triangle into that equation, then do it to the other triangle.
add the solutions to get 150 feet
then find the area of the rectangle: 20 x 40= 800
add 800 and 150 to get the total area: 950 feet

This is the third time I have asked this question. Someone please answer! Brainlist IF possible. Use the graph to write a linear function that relates y to x.
Since I have asked this same question three times, you can answer the copies for extra points. One is 8 points and the other 10.
Answer:
Use the graph to write a linear function that relates y to x. The points lie on a line. Find the slope and y-intercept of the line. Because the line crosses the y-axis at (0, −3), the y-intercept is −3.w
Step-by-step explanation:
There are three standard forms for linear functions y = f(x):
f(x) = mx + b (The "slope-intercept" form),
y - yo = m(x - x0) or, equivalently, f(x) = y0 + m(x - x0) (The "point-slope" or "Taylor" form), and.
Ax + By = C (The "general form") which defines y implicitly as a function of x as long as B 0.
