(1.5, 8)Step-by-step explanation:
We can see the coefficients of y are same in number but have opposite signs.
We need to add equations, this will eliminate y:
2x + 6x = 7 + 58x = 12x = 12/8x = 1.5Now find the value of y:
2(1.5) + 0.5y = 73 + 0.5y = 70.5y = 4y = 4/0.5y = 8Please help bro im stuck on this for hours, ill give u so much points

Step-by-step explanation:
Find the distance from point A to the given line.
1. A(−1, 7), y = 3x
and
2. A ( − 1 — 4 , 5 ), −x + 2y = 14
Answer:
The shortest distance from a point to a line is the perpendicular from the line to the point
The equation of the given line is -x + 2·y = 14, which can be written in slope and intercept form as follows;
-x + 2·y = 14
2·y = 14 + x
y = 14/2 + x/2 = x/2 + 7
y = x/2 + 7
The slope, m₁ = 1/2 and the y-intercept = 7
Therefore, the slope, m₂, of the perpendicular line to the line -x + 2·y = 14 which was rewritten as y = x/2 + 7 is m₂ = -1/m₁ = -1/(1/2) = -2
Therefore, we have that the slope of the line from A(-1/4, 5) to the line -x + 2·y = 14, is -2
The equation of the line is therefore;
y - 5 = -2(x - (-1/4))
y - 5 = -2·x - 1/2
y = -2·x - 1/2 + 5 = -2·x + 9/2
y = -2·x + 9/2
The coordinates of the point on the line -x + 2·y = 14 (y = x/2 + 7) that coincides with the perpendicular from the point A(-1/4, 5) is therefore given as follows;
-2·x + 9/2 = x/2 + 7
9/2 - 7= x/2 + 2·x
-2.5 = 2.5·x
x = -2.5/2.5 = -1
x = -1
y = x/2 + 7 = -1/2 + 7 = 6.5
y = 6.5
The coordinates of the point on the line -x + 2·y = 14 (y = x/2 + 7) that coincides with the perpendicular from the point A(-1/4, 5) is (-1, 6.5)
The distance from A(-1/4, 5) to B(-1, 6.5), is given as follows;
Where;
(x₁, y₁) = (-1/4, 5), and (x₂, y₂) = B(-1, 6.5)
Plugging in the values, we have;
Therefore, the distance from A(-1/4, 5) to the line -x + 2·y = 14 ≈ 1.7 units, rounding to the nearest tenth.
milagros observa la maqueta del proyecto inmobiliario para un centro de capacitacion destinado a estudiantes universitarios que deseen hacer sus practicas preprofesionales en comunidades del interior de nuestro pais y necesiten conocer mas sobre ellas . en la maqueta el largo del terreno sobre el que se realizara la construccion mide 90cm , lo que en la realidad mide 45m ¿ que escala se ha utilizado en la elaboracion de la maqueta?
Queremos encontrar la escala que se ha utilizado para la elaboración de la maqueta.
Veremos que la escala utilizada es 1cm = 0.5m
Para encontrar la escala, tenemos que ver la relación entre la medida de la maqueta y la medida real.
Sabemos que:
largo en la maqueta = 90cmlargo real = 45mLo que tenemos que ver es cuanto representa cada centimetro en la maqueta.
Asi, tenemos la relación:
90cm = 45m
90cm/90 = 45m/90
1cm = 0.5m
Es decir, cada centimetro en la maqueta representa 0.5 metros en la realidad, es decir, la escala utilizada es:
1cm = 0.5m

Answer:
Linear function, zero slope
Step-by-step explanation:
Definition of a horizontal lineA horizontal line neither rises nor falls and has a zero slope. Hence, the equation y = mx + b becomes y = b, where b is the y-intercept. The selected option for the equation of the given graph is correct, that y = 5.
Definition of a functionA function is a relation where any x-coordinate cannot be paired with more than one y-coordiante. Consequently, if a graph contains two or more different points with the same first coordinate, the graph cannot represent a function.
Vertical line testA great way to test whether a given graph represents a function is by performing the vertical line test. The vertical line test states that if each vertical line drawn intersects the graph at exactly one point, then the relation is a function.
Attached is an edited screenshot of the given graph, showing the results of the vertical line test. The given graph is a function since each vertical line crosses the graph at most once. This implies that each x-coordinate corresponds to exactly one y-coordinate.
Therefore, the given graph represents a linear function with a zero slope.

when the product (3x-2) (2x^2 + 7x-1) is found,
what is the coefficient of the linear term?
The linear term is the term with a degree of 1, hence the coefficient of the linear term is -11
Given the functions (3x-2) (2x^2 + 7x-1)
Taking the product of the functions will give:
(3x-2) (2x^2 + 7x-1) = 3x(2x^2) + 3x(7x) + 3x - 4x^2 - 14x + 2
(3x-2) (2x^2 + 7x-1) = 6x^3+21x^2 -11x - 4x^2 + 2
(3x-2) (2x^2 + 7x-1) =6x^3+17x^2 - 11x + 2
The linear term is the term with a degree of 1, hence the coefficient of the linear term is -11

f(x)=4x+11 If f(x) = -1 what is the value of x
Answer:
Since both equations equal to f(x), you can set 4x+11 equal to -1 and solve for x.
4x+11=-1
Subtract 11 from both sides.
4x=-12
Divide both sides by 4.
x=-3

Answer:
x=125º
2x=250º
Step-by-step explanation:
720 is the sum of the interior angles of a Hexagon
720=60+65+120+100+3x
720=345 +3x
-3x=345-720
-3x=-375
-x=-125
x=125
Answer:
x= 125
2x= 250
Step-by-step explanation:
720-120-100-65-60=375
x is slightly bigger than 120 so I made it 125
and 2x is huge so it was obviously the remainder which is 250

Given a set of data with mean of 12 and variance of 84. When each of the data is added with p and multiply with q, the new mean is 51 and the new variance is 756. Find the value of p and of q.
Applying statistical concepts, it is found that the values are:
p = -11.37q = 81When a constant is added to each data in a variable:
The mean is incremented by this constant.The variance remains constant.When a constant is multiplied to each data in a variable:
The mean is multiplied by this constant.The variance is multiplied by the square of this constantHence, mean of 12, added with p and multiplied with q, for a mean of 51:
[tex](12 + p)q = 51[/tex]
Variance of 84, after the operations, 756:
[tex]84\sqrt{q} =756[/tex]
[tex]\sqrt{q} = \frac{756}{84}[/tex]
[tex]\sqrt{q} = 9[/tex]
[tex](\sqrt{q})^2 = 9^2[/tex]
[tex]q = 81[/tex]
For p:
[tex](12 + p)q = 51[/tex]
[tex](12 + p)81 = 51[/tex]
[tex]12 + p = \frac{51}{81}[/tex]
[tex]12 + p = 0.63[/tex]
