2x-4y=8 and 7x-3y=61 solve by substitution
Answers
Answer:
(10, 3)
Step-by-step explanation:
Solve by Substitution
2x − 4y = 8 and 7x − 3y = 61
Solve for x in the first equation.
x = 4 + 2y 7x − 3y = 61
Replace all occurrences of x with 4 + 2y in each e quation.
Replace all occurrences of x in 7x − 3y = 61 with 4 + 2y. 7 (4 + 2y) − 3y = 61
x = 4 + 2y
Simplify 7 (4 + 2y) − 3y.
28 + 11y = 61
x = 4 + 2y
Solve for y in the first equation.
Move all terms not containing y to the right side of the equation.
11y = 33
x = 4 + 2y
Divide each term by 11 and simplify.
y = 3
x = 4 + 2y
Replace all occurrences of y with 3 in each equation.
Replace all occurrences of y in x = 4 + 2y with 3. x = 4 + 2 (3)
y = 3
Simplify 4 + 2 (3).
x = 10
y = 3
The solution to the system is the complete set of ordered pairs that are valid solutions.
(10, 3)
The result can be shown in multiple forms.
Point Form:
(10, 3)
Equation Form:
x = 10, y = 3
X=8+4y/2 so X= 4+2y. (Divide both sides by 2)
Sub in 4+2y for x so 7(4+2y)-3y=61
Distribute: 28+ 14y -3y=61
Subtract 28 and add the y’s. 11y=33
Y=3

Please help me with this question!!!!!!!
Answers
Answer: x=12
Step-by-step explanation:
The Pythagorean theorem is a²+b²=c². A and b are the legs, and c is the hypotenuse. Since we are only given the length of a leg and hypotenuse, we fill in what we have and solve for a.
a²+16²=20² [exponent]
a²+256=400 [subtract both sides by 256]
a²=144 [square root both sides]
a=12
Now, we know the missing leg, x=12.

Blas y Raul se han colocado en línea recta en lados opuestos de un generador eólico para medir su altura el terreno es llano y los dos amigos están separados por 41 m cada uno desde su posición mide el ángulo con el que se ve el generador desde el suelo qué altura tiene el generador
Answers
Answer:
La pregunta esta incompletea porque no incluye el angulo de Raul y el angulo de Blas. Busque un ejemplo similar y encontre que el angulo de Blas es 60° y el de Raul es 45°. Suponiendo que ambos midieron el angulo desde el suelo:
tangente 60° = altura / (41 - d)
tangente 45° = altura / d
altura = (41 - d) · tangente 60° = (41 - d) · 1.73205
altura = d · tangente 45° = d · 1
d = 71.01408 - 1.73205d
2.73205d = 71.01408
d = 71.01408 / 2.73205 = 25.993 ≈ 26 metros
sustituimos:
altura = d · tangente 45° = 26 · 1 = 26 metros
La altura del generador es de 26 metros

Answer:
-101 feet
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you that the relevant relation is ...
Tan = Opposite/Adjacent
Opposite = Adjacent × Tan
height = (0.5 × 5280 ft) × tan(47°) ≈ 2831 ft
__
The usual relation between estimates and errors is ...
error = estimate - actual
Then ...
actual = estimate - error
For the given angle and error, the actual angle is ...
actual angle = 47° -(-1°) = 48°
actual height = (2640 ft)·tan(48°) ≈ 2932 ft
Then the change in the height of the mountain due to the error is ...
2831 ft -2932 ft = -101 ft
The error of -1° in angle estimate creates an error of -101 ft in the height estimate.

Write in slope intercept form of the equation of the line parallel to y= -2x + 5 and that passes through the point (3,1)
Answers
Answer:
y = -2x + 7
Step-by-step explanation:
In a equation thats parallel to y = -2x + 5, we have the same slope but different y intercepts (b).
SO we plug in point (3, 1) into y = mx + b
y = -2x + b
1 = -2(3) + b
1 + 6 = b
b = 7
So just plug in b back into the equation
y = mx + b
y = -2x + 7
Answer:
Step-by-step explanation:
y= -2x + 7
using point-slope formula:
y - y1 = m(x - x1)
Substitute:
y - 1 = m(x - 3)
Now, what is m and how do we find it?
m represents the slope. To find the slope in this circumstance, we have to look at the equation that we were given in the problem.
y= -2x + 5
Since we are trying to find a line parallel to this equation, we will be using the same slope that this uses.
The slope in the equation is -2.
Let’s substitute -2 for m.
y - 1 = -2(x - 3)
Now distribute:
y - 1 = -2x +6
Add 1 to both sides:
y = -2x + 7
Now we have an equation in slope-intercept form that is parallel to y= -2x + 5 and runs through the point (3, 1).
