Answer:
y = 15
x = 43
Step-by-step explanation:
this is giving us a system of equations because we know two things:
x + y = 58
x - y = 28
take the second equation and format it where you have simplified it for one variable:
x = 28 + y
(we did this by adding y to both sides)
now substitute this new value of x into the <em>first </em>equation:
28 + y + y = 58
simplify this to get 2y = 30
divide both sides by 2: y = 15
now substitute your new value of y into the <em>second </em>equation:
x = 28 + 15
x = 43
Answer:
X=$5000 in sales
Step-by-step explanation:
You can write an equation in slope-intercept to find an answer.
<em>y=0.2x+1000</em>, 20% commission is the slope and the base pay is the y-intercept.
Now, just plug in 2000 for y.
<em>2000</em><em>=</em><em>0.2x</em><em>+</em><em>1000,</em><em> </em>subtract 1000.
<em>1000</em><em>=</em><em>0.2x,</em><em> </em>Multiply by 5 to get x by itself.
<em>5000</em><em>=</em><em>x</em><em>.</em>
Opciones:
A) (-8, -7)
B) (0, 1)
C) (0, 2)
D) (3, 4)
Responder:
(0, 2)
Explicación paso a paso:
Dado :
y = (x + 1)
Para probar qué puntos no pertenecen; aplicamos la ecuación a las opciones dadas para ver cuál de las opciones no se ajusta a la ecuación:
(x = -8, y = - 7)
y = (x + 1)
y = - 8 + 1
y = - 7
(x = 0, y = 1)
y = 0 + 1
y = 1
(x = 0, y = 2)
y = 0 + 1
y = 1
El punto (0, 2) no pertenece
(x = 3, y = 4)
y = 3 + 1
y = 4
It is 0.2 x 0.4
The green part is 20 squares and the yellow part is 40 squares. The intersection has 8 squares which means the answer is 0.08
Answer:
0.02 m/sec
Step-by-step explanation:
26/30=0.89 —> 0.89 min —> 53.4 sec
42/50=0.84 meters
speed=0.84 / 53.4 = 0.015 m/sec = 0.02 m/sec
