2x-3 = -2x + 5
4x = 8
x = 2
y = 2*2 - 3 = 1
(2 ; 1)
you have to draw the 2 lines
the solution will be the intersection point of the 2 lines
Answer:
[D] (2,1)
Step-by-step explanation:
Given;
y=2x-3
y=-2x + 5
Solve;
y = 2x - 3 . . . [Equation 1]
y = -2x + 5 . . . [Equation 2]
[Equating 1 and 2]
2x - 3 = -2x + 5
2x + 2x = 5 + 3
4x = 8
x = 8/4 = 2
x = 2
y = 2(2) - 3 = 4 - 3 = 1
y = 1
Solution = (2, 1)
Hence, Answer = [D] (2,1)

Porfavor para hoy dice el papa de Rafael va a construir una picina afuera de su casa en forma de cuadrado en el area de 121 pies cuadradas. Alrededor de la picina quiere construir una plataforma de cuatro pies de ancho, Explicale a Rafael paso apaso como calcular el perimetro de la plataforma, Despues me dice que explique paso a paso en mis propias palabras como calcular el perimetro de la plataforma
Answer:
Deducir ecuación de área del cuadrado/Despejar y calcular longitud de lado/Deducir ecuación de perímetro/Calcular perímetro del cuadrado.
Perímetro: 44 pies cuadrados.
Step-by-step explanation:
Podemos explicarle al papa de Rafael lo siguiente:
Estimado señor.
Una piscina de forma cuadrada tiene la forma de un cuadrilátero con cuatro lados iguales y cuatro ángulos rectos en sus vértices. El área del cuadrado es igual a la longitud de cualquiera de sus lados multiplicada por si misma. Es decir:
[tex]A = l\cdot l = l^{2}[/tex] (Eq. 1)
Entonces, la longitud de cualquiera de sus lados es la raíz cuadrada del área de su piscina. Es decir:
[tex]l =\sqrt{A}[/tex] (Eq. 1b)
Donde [tex]l[/tex] y [tex]A[/tex] son la longitud de lado y el área de la piscina, medidos en pies y pies cuadrados, respectivamente.
Si sabemos que su piscina tiene un área de 121 pies cuadrados ([tex]A = 121\,ft^{2}[/tex]), entonces la longitud del lado de piscina es:
[tex]l = \sqrt{121\,ft^{2}}[/tex]
[tex]l = 11\,ft[/tex]
Tenemos que la longitud del lado es 11 pies.
Ahora, el perímetro es la suma de las longitudes de los lados del cuadrado. Si el cuadrado tiene 4 lados de igual medida, entonces el perímetro del cuadrado es igual a cuatro veces esa longitud. Esto es:
[tex]p = 4\cdot l[/tex] (Eq. 2)
Donde [tex]p[/tex] es el perímetro, medido en pies.
Si conocemos que la longitud del lado es 11 pies ([tex]l = 11\,ft[/tex]). En consecuencia, encontramos que el perímetro de su piscina es:
[tex]p = 4\cdot (11\,ft)[/tex]
[tex]p = 44\,ft[/tex]
El perímetro de su piscina es de 44 pies.

Answer:
81%
Step-by-step explanation:
First, let's set up 3 equations:
w*0.6 = x
x*1.5=y
y*0.9=z
Now, we can substitute x in the second equation for w*0.6:
w*0.6*1.5 = y
Lastly, we can substitute y in the last equation for w*0.6*1.5:
w*0.6*1.5*0.9=z
w*0.81=z
Therefore, z is 81 percent of w.

If you add 10 grams of sugar into 30 grams of 20 % sugar syrup, you will make ____ grams of ____% sugar syrup.
Answer:
40 grams of 40% sugar syrup
Step-by-step explanation:
20% of 30 grams = 6grams of sugar
6 grams + 10 grams = 16 grams of 40% instead of 30 now
Therefore, 40g----------100%
16g-----------40%
Answer:
40 grams of 40% sugar syrup
Step-by-step explanation:
40 grams of 40% sugar syrup
30+10== 40 g
20% sugar in 30 = 1/5 of the syrup is sugar. = 6 g of sugar
6+10 = 16g of sugar in 40 grams of syrup.
16/40=x/100

A warehouse contains 55 boxes. Then a truck delivers a number of boxes at 12:00 p.m. and the team begins to unload them immediately . by 3:30 pm, the warehouse contains 90 boxes. supposes the boxes are unloaded at a constant rate. write a formula that shows that total number of boxes in the warehouse as a function of time where Q(t) is the total number of boxes, and t is the time since noon.
I WILL GIVE BRAINLIEST!!!!!!!!!!!!!
The function that shows this situation is given by Q(t) = 3.5t + 55
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y, x are variables, m is the rate of change and b is the y intercept.
Let Q(t) represent the total number of boxes, and t is the time since noon in hours.
A warehouse contains 55 boxes, hence b = 55. At 3:30 pm (3.5 hours), the warehouse contains 90 boxes.
90 = 3.5m + 55
m = 10
The function that shows this situation is given by Q(t) = 3.5t + 55

What is the equation of the translated function? f(x) = (x – 1)2 – 5 f(x) = (x 1)2 5 f(x) = (x – 5)2 – 1 f(x) = (x 5)2 1
The equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5
What will be the equation?The vertex of the original function is (0, 0 )
The vertex of the translated function is (- 1, 5 )
Given f(x) then f(x + a) represents a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
The translated graph has been shifted 1 unit left, thus
f(x) = (x + 1)²
Given f(x) then f(x) + c represents a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
The translated graph has been shifted 5 units up,
Thus the equation of the translated function will be given by f(x) = ( x + 1 ) 2 + 5

Which represents the distance between A(2, 3) and B(-1,-1)?
Answer:
5 units
Step-by-step explanation:
(x1, y1) =A(2,3)
(x2,y2) =B(-1,-1)
Using distance formula,
AB^2 = (x2-x1) ^2 +(y2-y1) ^2
=(-1-2)^2 +(-1-3)^2
=9+16
=25
Therefore, AB=5 units

Points X and Z are on a number line, and point Y partitions line XZ into two parts so that the ratio of the length of line segment XY to the length of line segment YZ is 1:4. The coordinate of X is 1.3, and the coordinate of Y is 3.8. What is the coordinate of Z?
Answer:
13.8Step-by-step explanation:
if Points X and Z are on a number line and point Y partition line XZ into two parts where XY: YZ = 1:4, this can be expressed as;
XY/YZ = 1/4
cross multiply;
YZ = 4XY
Also, if The coordinate of X is 1.3, and the coordinate of Y is 3.8, then the distance XY will be expressed as XY = 3.8 - 1.3
XY = 2.5
YZ = 4(2.5)
YZ = 10
Since Y is at 3.8 and YZ is 10, then coordinate Z will be YZ + Y
coordinate of Z = 10+3.8
coordinate of Z = 13.8

1.
[tex]2x + y = 1[/tex]
Slope intercept form :
[tex]y = - 2x + 1[/tex]
Equation :
[tex]x - 2y = 8[/tex]

Slope intercept form :
[tex]2y = - 3x + 4 \\ [/tex]
Divide through by 2
[tex]y = - \frac{3}{2} x + 2[/tex]
Equation :
[tex]x + 2y = - 4[/tex]

Determine the equation of the Logarithmic Regression that models the data. Then use your equation to determine the amount of sunlight (%) that penetrates to a depth of
150m. Express you answer to the nearest hundredth of a percent
Answer:
Percentage of light that penetrates at 150 m will be 0.94%.
Step-by-step explanation:
By using logarithmic regression calculator,
Equation of the regression line will be,
y = 104.5173 - 20.6711(lnx)
Where x represents the depth of the ocean
And y will represent the penetration of light
Therefore, at the depth of 150 m, penetration of the light will be,
y = 104.5173 - 20.6711[ln(150)]
= 104.5173 - 103.5753
= 0.9420
≈ 0.94 %
Therefore, percentage of light that penetrates at 150 m will be 0.94%.
