Solve the inequality and graph the solution on the line provided. 4 + 6 x < 4

Answers

Answer:

inequality: x<0

Step-by-step explanation:

Given that f(x) = x^2– 5x– 36 and g(x) = x + 4, find (f +9)(x) and express
the result in standard form.

Answers

Answer:

x^2 -4x-32

Step-by-step explanation:

f(x) = x^2– 5x– 36

g(x) = x + 4

(f +g)(x) = x^2– 5x– 36  +  x + 4

Combine like terms

            = x^2 -4x-32

Answer:

[tex] \longmapsto \: f(x) = {x}^{2} - 5x - 36 \\ \longmapsto \: g(x) = x + 4 \\ \longmapsto(f + g)(x) \\ = f(x) + g(x) \\ = ( {x}^{2} - 5x - 36) + (x + 4) \\ = {x}^{2} - 5x - 36 + x + 4 \\ = \boxed{ {x}^{2} - 4x - 32}[/tex]

(D)

Step-by-step explanation:

Becuase 81 is greater than 9 and 9 is less than 12 (I hope this helps) :)

Step-by-step explanation:

12 less ( subtracting 12 from something else)

the quotient-Dividing between two values

A number: let's use Y

so we want to substract 12 from the product of y/9

(Y/9) -12.

So 81 is greater than 9 but 9 is less than 12.

Answer:

m∠1 = 52, m∠2 = 60

Step-by-step explanation:

68 and ∠2 are interior angles. 128 is exterior angle.

Formula : -

Sum of two interior angles = Exterior angle

68 + ∠2 = 128

∠2 = 128 - 68

∠2 = 60

∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,

∠1 + 128 = 180

∠1 = 180 - 128

∠1 = 52

Produce a function f(x) that satisfies the following conditions: 1. Its domain is all real numbers. 11. It has no maximum and no minimum on the interval (1, 3). III. It satisfies f(1) = 1 and f(3) = -1, but there does not exist a c between 1 and 3 such that f(x) = 0. B. Construct a function f(x) that satisfies the following conditions: C. fis continuous for all x. ​

Answers

Answer:

C.  Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

Line segment XY has endpoints X(5,7) and Y(-3,3)

Answers

y=-2x+7

Step-by-step explanation:

line segment xy has endpoints x(5 7) and y(-3 3)

for the equation of the perpendicular bisector of line segment xy

slope of line segment xy = 7-3 / 5+3

= 4/8

=1/2

so slope of perpendicular bisector is -2

as m1m2= -1 or m1= -1/m2

As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy

midpoint(x,y) = (5-3 / 2 , 7+3 / 2)

=(2/2, 10/2)

=(1,5)

find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2

y-5 = -2(x-1)

y-5 =-2x+2

y=-2x+7
