x-3y=0
3y-6=2x
(-2,-6)
(-6,-1/2)
(-6,-2)
Answer:
C, (-6,-2)
Step-by-step explanation:
x - 3y = 0 --(1)
3y - 6 = 2x --(2)
We can rearrange equations 1 and 2:
3y - x = 0 --(3)
3y - 2x = 6 --(4)
Subtract 4 from 3:
(3y-3y) + (-2x+x) = (6-0)
-x = 6
x = -6
Substitute x=-2 into any equation. In this case, I substituted it into equation 1 but the value of y would be the same if you substituted it into a different equations:
x - 3y = 0
-6 = 3y
y = -2
Let's check to see if we are right but substituting the values of x and y into both equations
x - 3y = 0
-6 + (-3*-2) = 0
-6 + 6 = 0
0 = 0 Correct
3y - 6 = 2x
3(-2) - 6 = 2(-6)
-6 - 6 = -12
-12 = -12 Correct
Our answer is correct!

During bowling practice, Marley rolled 14 strikes out of 70 attempts.
What percent of Marley’s attempts were strikes? Enter your answer in the box.
Answer:
20%
Step-by-step explanation:
to find out we make it a fraction:
14/70
then divide
14÷70=0.2
then times it by 100
= 20%
Answer:
20%
Step-by-step explanation:
[tex]\frac{14}{70}[/tex] = [tex]\frac{x}{100}[/tex]
14 x 100 = 1400
1400/ 70 = 20%

Enter an equation in point-slope form for the line. (6,8) and (7,1) is on the line. The equation of the line in point slope form is:
Answer:
[tex] y - 8 = -7(x - 6) [/tex] or [tex] y - 1 = -7(x - 7) [/tex]
Step-by-step explanation:
The point-slope form equation is [tex] y - b = m(x - a) [/tex], where,
(a, b) = a point on the line.
[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Given the two points, (6, 8) and (7, 1), find the slope of the line:
[tex] m = \frac{1 - 8}{7 - 6} [/tex]
[tex] m = \frac{-7}{1} [/tex]
[tex] m = -7 [/tex]
There are two possible point-slope equation we can come up with using each points on the line given.
Using the point (6, 8) and m = -7,
Substitute m = -7, a = 6, and b = 8 into [tex] y - b = m(x - a) [/tex]
[tex] y - 8 = -7(x - 6) [/tex]
Using the point (7, 1) and m = -7,
Substitute m = -7, a = 7, and b = 1 into [tex] y - b = m(x - a) [/tex]
[tex] y - 1 = -7(x - 7) [/tex]

Diana y Juan están considerando abrir una cafetería. Semanalmente ellos gastarian
$1.348 en costos fijos de utilidades y mantenimiento. Cada almuerzo tiene un costo
de producción de $3.50. por lo que piensan vender cada almuerzo en $8.
a. ¿Cuántos almuerzos deben elaborar semanalmente si desean obtener una
ganancia de $775 para cada uno?
Answer:
Unidades a vender= 644 unidades
Step-by-step explanation:
Dada la siguiente información:
Costos fijos= $1.348
Costo unitario= $3,5
Precio de venta= $8
Ganancia deseada= 775*2= $1.550
Para calcular el número de unidades a vender, debemos usar la siguiente formula:
Unidades a vender= (costo fijo + ganancia deseada) / contribución marginal unitara
Unidades a vender= (1348 + 1550) / 4,5
Unidades a vender= 644 unidades
what is the least common deno minator 2/5 and 3/2
Answer: 10
Step-by-step explanation: The common denominator for these two
fractions is simply the least common multiple for the two denominators.
Since our denominators of 5 and 2 have no factors in common,
our least common denominator is 5 · 2 or 10.
use the diagram to solve x and y
Answer:
x = 54°
y = 144°
Step-by-step explanation:
x° + 36° = 90° (complementary angles)
Subtract 36° from each side of the equation
x° = 90 - 36°
x = 54°
y° + 36° = 180° (angles on a straight line/supplementary angles)
Subtract 36° from each side
y° = 180° - 36°
y = 144°
Sarah mailed her computer to Store B for repairs. Her bill was:
Initial Repair Cost = $1,350
Sales Tax of 7 percent = $94.50
Total Cost of Computer Repair = $1,444.50
Shipping = 2 percent of Total Cost
Which expression would you use to find the shipping cost?
0.2($1,350)
0.2($1,444.50)
0.02($1,350)
0.02($1,444.50)
Answer:
0.02 (1444.50)
Step-by-step explanation:
Answer:0.02(1444.50)
Step-by-step:
to figure out the shipping cost we would just multiply the shipping percent by the total cost of the computer. however we cant leave the '2 percent' as it is we would have to multiply it by 100. giving us .02 which we can then use to multiply
