Subtract 7.4−3.6 is the first step in evaluating the expression

In mathematics, an expression or mathematical expression exists as a finite combination of signs that stands well-formed according to laws that depend on the context.

The Bodmas rule is arranged according to the letters in the acronym BODMAS, which stand for brackets, order of powers or roots, division, and multiplication. A stands for addition and S for subtraction. According to the BODMAS rule, multi-operator mathematical equations must be resolved in the BODMAS order from left to right.

We know that

In mathematics, a graph is a diagram that is used to represent a relationship between the two variables one is a independent variable and the other is a dependent variable.

It is just the set of all the ordered pairs of the type: (x,y) where x is the domain of the function and y is the range of the function.

Answer:

B. [tex]m\angle CAD=\frac{m\widehat {CD}-m\widehat {GE}}{2}[/tex].

Step-by-step explanation:

We have been given an image of a circle. We are asked to find the measure of angle CAD.

We can see that angle CAD is formed by two intersecting secants outside the circle.

Intersecting secants theorem states that when two secants intersects outside a circle, then the measure of angle formed by secants is half the difference of intercepted arcs.

[tex]m\angle CAD=\frac{\text{Larger arc-Smaller arc}}{2}[/tex]

[tex]m\angle CAD=\frac{m\widehat {CD}-m\widehat {GE}}{2}[/tex]

Therefore, option B is the correct choice.

Answer:

the number of non-farm jobs  started going down in 2008

Step-by-step explanation:

The question presented requires the analysis and interpretation of graphical output of data.

From the graph it is true to say that the number of non-farm jobs did not remain consistent over time since the graph is moving down then up implying decrease followed by increase.

It is also true to say that the number of non-farm jobs started going up in 2010 as indicated by the upward trend of the graph.

From 2008 to around 2010 the graph is moving downwards suggesting that the number of non-farm jobs was declining.

C) 23 yd^2

Step-by-step explanation:

We can break  this figure into two rectangles.

One rectangle is a vertical triangle that is 3 yd across by 7 yds down

The area of this figure is

A = lw

   = 3 * 7 = 21

The other rectangle is 1 yd across and by 2 yds down  

The area of this figure is

A = lw

   = 1 * 2 = 2

The total area is the sum of the two figures

A = 21 +2 = 23

Answer:

(d)

Step-by-step explanation:

(d) is correct.  This being a 5th power of x, the graph starts in Quadrant III and continues growing into Quadrant I.  This is true of any positive odd power of x.

The best statement describes The graph of the function starts low and ends high.

The Option (d) is correct.

The end behavior of a polynomial function is determined by its leading term, which is the term with the highest degree. The coefficients of the leading term also play a significant role.

For the function [tex]\( F(x) = 3x^5 + 4x^3 - x + 11 \)[/tex], the leading term is[tex]\( 3x^5 \)[/tex]. Since the coefficient of[tex]\( x^5 \)[/tex] is positive, as[tex]\( x \)[/tex] approaches positive infinity[tex](\( x \to \infty \))[/tex], the function [tex]\( F(x) \)[/tex] will go to positive infinity [tex](\( F(x) \to \infty \))[/tex]. Similarly, as[tex]\( x \)[/tex]approaches negative infinity [tex](\( x \to -\infty \)),[/tex] the function [tex]\( F(x) \)[/tex] will go to negative infinity [tex](\( F(x) \to -\infty \))[/tex] because the leading term, being an odd power with a positive coefficient, will dominate and the sign will be negative due to the odd power.

So, the end behavior of the function is:

- Starts low (as[tex]\( x \)[/tex] goes to negative infinity,[tex]\( F(x) \)[/tex] goes to negative infinity).

- Ends high (as[tex]\( x \)[/tex] goes to positive infinity, [tex]\( F(x) \)[/tex] goes to positive infinity).

This corresponds to option D: "The graph of the function starts low and ends high."

61-61

90-61

x=29

Answer: 29

Step-by-step explanation:

Add the right angle which would equal 90 degrees with the 61 degrees. Now you get 151. Subtract 151 from 180, which is half of the circle. Now you have 29 degrees.

Simplify brackets

10x - 4 = 8x + 14

Add 4 to both sides

10x = 8x + 14 + 4

Simplify 8x + 14 + 4 to 8x + 18

10x = 8x + 18

Subtract 8x from both sides

10x - 8x = 18

Simplify 10x - 8x to 2x

2x = 18

Divide both sides by 2

x = 18/2

Simplify 18/2 to 9

x = 9

10x - 4 = 8x + 14

Step 1: Combine like terms

x's go with x's (10x and 8x). To do this subtract 8x to both sides

(10x - 8x) - 4 = (8x-8x) + 14

2x - 4 = 14

Normal numbers go with normal numbers (-4 and 14). To do this add 4 to both sides

2x + (-4 + 4) = 14 + 4

2x = 18

Step 2: Isolate x by dividing 2 to both sides

2x/2 = 18/2

x = 9

Answer:

c=3

Step-by-step explanation:

We have 2 points, we can find the slope using

m = (y2-y1)/(x2-x1)

Substituting into this equation

-1/4 = (4-5)/(7-c)

-1/4 = -1/(7-c)

Multiply both sides by -1

1/4 = 1/(7-c)

The denominators have to be the same

4 = 7-c

Subtract 7 from each side

4-7 = 7-7-c

-3 = -c

Multiply by -1

Answer:

A. Transformation

Step-by-step explanation:

Transformation is the responsible for the changing the size of the object without changing the shape. Then the correct option is A.

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The transformation is the process of making the shape of an object to be increased or decreased without changing the shape of the object that depends on the scale factor.

If the size of the object is increased then the scale factor is greater than one.

If the size of the object is decreased then the scale factor is less than one.

For this case we have two functions of the form y = f (x). We must find the quotient of the following functions:

[tex]f (x) = x + 2\\g (x) = 3x + 5[/tex]

So, we have by definition:

[tex]\frac {f (x)} {g (x)} = \frac {x + 2} {3x + 5}[/tex]

Answer:

[tex]\frac {f (x)} {g (x)} = \frac {x + 2} {3x + 5}[/tex]

with 3x + 5 different from zero, so that the function is defined

Step-by-step explanation:

The given functions are:

f(x) = x + 2 and g(x) = 3x + 5

[tex]\frac{f(x)}{g(x)}=\frac{x+2}{3x+5}[/tex]

Since this is a rational function, the function will not be defined where denominator equals zero.

Answer:

x = -4; y = 3

Step-by-step explanation:

-3x + 4y = 24

6x + 2y = -18

Rewrite the first equation as it is. Divide both sides of the second equation by 2 and write it below the first equation. Then add the equations.

         -3x + 4y = 24

+        3x  +  y = -9

----------------------------

                  5y = 15

Divide both sides by 5.

y = 3

Now plug in 3 into y in the first original equation and solve for x.

-3x + 4y = 24

-3x + 4(3) = 24

-3x + 12 = 24

-3x = 12

x = 12/(-3)

x = -4
