Step-by-step explanation:
(10)
let x represent blueberry pie and y blackberry pie, then
x + 2y = 53 → (1)
10x + 3y = 224 → (2)
Multiplying (1) by - 10 and adding to (2) will eliminate x
- 10x - 20y = - 530 → (3)
Add (2) and (3) term by term to eliminate x
0 - 17y = - 306
- 17y = - 306 ( divide both sides by - 17 )
y = 18
Substitute y = 18 into either of the 2 equations and solve for x
Substituting into (1)
x + 2(18) = 53
x + 36 = 53 ( subtract 36 from both sides )
x = 17
Then
the cost of 1 blueberry pie is $17 and 1 blackberry pie is $18

The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
(11)
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (4, 2) and (x₂, y₂ ) = (0, 3)
m = [tex]\frac{3-2}{0-4}[/tex] = - [tex]\frac{1}{4}[/tex]
The line crosses the y- axis at (0, 3 ) ⇒ b = 3
y = - [tex]\frac{1}{4}[/tex] x + 3 ← equation of line
(12)
(x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (4, 2)
m = [tex]\frac{2-1}{4+3}[/tex] = [tex]\frac{1}{7}[/tex] , then
y = [tex]\frac{1}{7}[/tex] x + b ← is the partial equation
To find b substitute either of the 2 points into the partial equation
Using (3, 1 ), then
1 = [tex]\frac{3}{7}[/tex] + b ⇒ b = 1 - [tex]\frac{3}{7}[/tex] = [tex]\frac{4}{7}[/tex]
y = [tex]\frac{1}{7}[/tex] x + [tex]\frac{4}{7}[/tex] ← equation of line

How do I graph y=2/3x-4
Answers
Step-by-step explanation:
In that equation it tells you that your slope is 2/3. It also tells you that your y intercept is -4. (Remember slope is written in y=mx+b) So first you plot your y value. (Remember that y intercept is up and down and slope is rise/fall over run) So your first point should be located at -4. Now you can began putting in your slope. Since your slope is positive, go up two and go to the right 3 times (rise/run). That's how you graph your equation.

y = 4x - 6
if x = - 1 Then
y = 4 * (- 4 ) - 6 = - 10
if x = 0
y = 4 * 0 - 6 = - 6
if x = 1
y = 4 * 1 - 6 = - 2
if x = 2
y = 4 * 2 - 6 = 2

x=10 and y=10 is it intercepting parallel or same line?
Answers
Answer:
Parallel lines have the same slope. Because the functions \displaystyle f\left(x\right)=2x+3f(x)=2x+3 and \displaystyle j\left(x\right)=2x - 6j(x)=2x−6 each have a slope of 2, they represent parallel lines. Perpendicular lines have negative reciprocal slopes. Because −2 and \displaystyle \frac{1}{2}

x−4 and \displaystyle h\left(x\right)=-2x+2h(x)=−2x+2 represent perpendicular lines.
Answer:
Intercepting.
Step-by-step explanation:
The line x=10 is a straight vertical line going through all the points where x=10, as the equation suggests.
The line y=10 is a horizontal line going through all the points where y=10.
When you graph them, they intersect in a perfect cross.

A mermaid has a terrarium that measures 42 inches × 10 inches × 9 inches. She also has a box that measures 3 inches × 3 inches × 3 inches. Every minute, the mermaid fills the box with sand from her backyard and then pours the sand into the terrarium. How many minutes does it take the mermaid to fill three-quarters of the terrarium with sand?
Answers
9514 1404 393
Answer:
105 minutes
Step-by-step explanation:
The volume of the terrarium is ...
V = LWH
V = (42 in)(10 in)(9 in) = 3780 in³
The volume of a box is ...
V = (3 in)(3 in)(3 in) = 27 in³
Then the number of boxes it takes to fill the terrarium is ...
(3780 in³)/(27 in³/box) = 140 boxes
The mermaid wants to fill it 3/4 full, so only needs 3/4 this number of boxes. That is 105 boxes. At the rate of 1 per minute, ...
it will take 105 minutes to fill 3/4 of the terrarium

A system of linear equations is shown below. 3x+5y=9 2x+3y=5 which ordered pair shows the solution to the system
Answers
Answer:
(-2,3)
Step-by-step explanation:
Given data
the system of linear equation is presented as
3x+5y=9-----1
2x+3y=5-----2
solve simultaneously
3x+5y=9-----1 X 2
2x+3y=5-----2 X3
subtracting 2 from 1
6x+10y=18
-6x+9y=15
0x+y=3
y= 3
put y= 3 in 1
3x+5(3)=9-----1
3x+15=9
3x= 9-15
3x= -6
x= -6/3
x= -2
Hence the ordered pair is (-2,3)

The price of all rail tickets increased by 5 %.
The price of a rail ticket from London to Ipswich increased by £2.30
Work out the price of the ticket before the increase.
Answers
Answer:
Step-by-step explanation:
New price = (1 + 5%) x old price
New price = 1.05 x old price
old price = 2.3 / 1.05
Old price = £2.19
9514 1404 393
Answer:
£46
Step-by-step explanation:
The increase is ...
0.05 · price = £2.30
Multiplying by 20 gives ...
price = 20(£2.30) = £46.00
The price of the ticket before the increase was £46.00.

Una empresa fabrica dos modelos de DVD: el modelo A y el modelo B. Se dispone de 50 kilogramos de caucho y de 80 horas de mano de obra. Para fabricar un DVD del modelo A se utiliza 1 kilogramo de caucho y 1 horas de trabajo, y para fabricar un DVD del modelo B se utiliza 1 kilogramo de caucho y 2 hora de trabajo. Si la venta le genera una utilidad 30 soles por cada modelo A y 40 soles por cada modelo B. ¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?
Answers
Answer:
¿Cuántos DVD de cada tipo debe fabricar y vender para que la utilidad sea máxima?
Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800
Step-by-step explanation:
x : Número de DVD del modelo A
y : Número de DVD del modelo B.
MODELO A MODELO B TOTAL
Cantidad de caucho 1x 1x 50 kg.
Horas de mano de obra 1x 2x 80 horas
U : Utilidad mensual.
La función objetivo, que se debe maximizar, es:
U=30 + 40y
x+ y [tex]\leq 50\\[/tex]
x + 2y [tex]\leq 80[/tex]
x[tex]\geq 0[/tex]
y[tex]\geq 0[/tex]
Las coordenadas de los vértices de la región factibles son:
A (0, 0) B (50, 0) C (20, 30) D(0, 40)
Entonces, se evalúa la función objetivo en cada punto:
U (0, 0) = 30 (0) + 40 (0) = 0
U (50, 0) = 30 (50) + 40(0) = 1500
U (90, 0) = 30 (20) + 40 (30) = 1800
U (0, 40) = 30 (0) + 40 (40) =1600
Por consiguiente U tiene un valor máximo en C , en donde: x =20 , y = 30 .
Se debe fabricar y vender 20 DVD del modelo A y 30 DVD del modelo B. La utilidad máxima es de de S/. 1 800.
