Answer:
B
Step-by-step explanation:
-3 < 2x + 3 <= 5
-6 < 2x <= 2
-3 < x <= 1
such a condition is an "and" condition. both parts need to be fulfilled.
-3 < x and x <= 1
if you are still not seeing it :
-3 < x is the same as x > -3
now you see that B is the right answer.
x > -3 and x <= 1
Answer:
9y-3y=6y is equivalent to 9y – 3y.
80 is correct each of the triangles are 2x2/2 therefore 1 triangle is 2 multiples by 4 so all triangles equal to 8 units. The rectangles are 6 by 2 so 6 multipled by 2 multiplied by 2 again because there are 2 rectangles is 24. 8+24=32. Middle section is 8x6 and that equals to 48. 48+32 is 80 therefore the area of this figure is 80 units
52=x because x+128=180 and that is a 189 angle
Given that the debt has been represented by the function:
f(x)=-6x^2+8x+50
To get the number of years, x that it would take for the company to be debt free we proceed as follows:
we solve the equation for f(x)=0
hence:
0=-6x^2+8x+50
solving for x using the quadratic formula we get:
x=[-b+/-sqrt(b^2-4ac)]/2a
x=[-8+/-sqrt(8^2-4*(-6)*50)]/(-6*2)
x=[-8+/-√1264]/(-12)
x=27.552
x~28
