Answer::.x=6,y=2
3x - 5y = 8......(1)
X - 5y = - 4......(2)
subtracting equation 2 from 1 we get
Step-by-step explanation:
3x - 5y = 8
X - 5y = - 4
-
------------------
2x=12
x=12/2=6
multiplying equation 2 by3 weget
3x-15y=-12........(3)
subtracting equation 1from 3
3x-15y=-12
3x-5y=8
-
------------------
-10y=-12-8
y=-20/-10=2
Total number of computers in sample = 72 + 112 + 711 = 895.
P(LQ) = 72/895 = 0.08
P(MQ) = 112/895 = 0.125
P(HQ) = 711/895 = 0.794
Answer:
The fourth graph (last graph)
Step-by-step explanation:
Remember that the zeros of a function are the x-intercepts of the graph. To find the zeros we just need to set the function equal to zero and solve for x:




Now we know that the graph or our function intersects the x-axis at x = 1 and x = -4.
Since both x values inside the parenthesis are positive, our parabola is opening upwards.
The only graph opening upwards whose x-intercepts are x = 1 and x = -4 is the fourth one.
We can conclude that the graph of
is the fourth one.
The Correct Answer is C)3 Just divide 6/2 Then you end up with 3
