The unknown number is x .

An equation to find the value of x :-

[tex]x + 5 = - 4[/tex]

Let us solve this equation :-

[tex]x + 5 = - 4[/tex]

[tex]x = - 4 - 5[/tex]

[tex]x = - 9[/tex]

The value of x is -9 . Let us place -9 in the place of x , to check whether or not we have found out the correct value of x .

So :-

[tex] - 9 + 5 = - 4[/tex]

[tex] - 4 = - 4[/tex]

[tex]LHS = RHS [/tex]

As the left hand side of the equation is equivalent to the right hand side of the equation, we can conclude that we have found out the correct value of x .

Therefore , -9 + 5 = -4 and ( x = -9 ) .

5+x=-4 is equation of sentence 5 more than a number x is -4 and -9 is the solution of equation.

Two or more expressions with an Equal sign is called as Equation.

The given sentence is 5 more than a number x is -4.

Whenever there is a more than in a sentence means added with some number.

Let us consider the number be x.

5 more than a number x is -4 means 5 is added to number x which gives -4.

5+x=-4

This is the equation for the sentence.

Now let us solve the equation.

5+x=-4

Subtract 5 from both sides

x=-4-5

x=-9

Hence, 5+x=-4 is equation of sentence 5 more than a number x is -4 and -9 is the solution of equation.

The inverse of any function is where you sway the 'y' and 'x' positions.

Thus if the equation is [tex]y = 4x[/tex]

The inverse is:

  [tex]x = 4y\\y = \frac{1}{4} x\\[/tex]

Therefore the inverse is  [tex]h(x) = \frac{1}{4} x[/tex]

idrk about the second question though sorry!

Answer:

The numbers are 20 and 10.

Step-by-step explanation:

Let's say these teo numbers are x and y.

The sum of two numbers is 30

x + y = 30
Isolate y
y = 30 - x

Their quotient is 2
plug the newfound y value in the second equation.

x / y = 2

[tex]\frac{x}{30-x} = 2[/tex]

multiply both sides by (30 - x) to get rid of the fraction.

x = 2(30 - x)

x = 60 - 2x

x + 2x = 60 + 2x

3x = 60

dividie both sides by 3

x = 20

find y

y = 30 - x

y = 30 - 20 = 10
y = 10

The numbers are 20 and 10.

Answer:

10 and 20.

Step-by-step explanation:

x + y = 30

x/y = 2

x = 2y so substituting in the first equation:

2y + y = 30

y = 10

and  x + y =30

so x + 10 = 30  giving x = 20.

Answer:

Curtis will get $38.40 back

Step-by-step explanation:

First, we need to find out how much "real" money he has. The equation I did was:

50 + 30 + 30 + 8 = 118

Next, we must convert this into dollars, by multiplying by 0.325675

118 x 0.325675 = 38.42965

We round 38.42965 to the nearest penny:

38.42965

    -->   2 rounds down to 0, so we keep just the $0.40

our answer is:

$38.40

The only answer possible is 11 if we are talking whole numbers but something with decimals might work as well, I mean 22 only has 2 dividends and that is 11X2 and 22X1

keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above

[tex]y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{2}{9}} x-7\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}[/tex]

so then we can say that

[tex]\stackrel{~\hspace{5em}\textit{perpendicular lines have \underline{negative reciprocal} slopes}~\hspace{5em}} {\stackrel{slope}{-\cfrac{2}{9}} ~\hfill \stackrel{reciprocal}{-\cfrac{9}{2}} ~\hfill \stackrel{negative~reciprocal}{-\left( -\cfrac{9}{2} \right)\implies \cfrac{9}{2}}}[/tex]

so we're really looking for the equation of a line whos slope is 9/2 and passes through (2 , 3)

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{3})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{9}{2} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{\cfrac{9}{2}}(x-\stackrel{x_1}{2}) \\\\\\ y-3=\cfrac{9}{2}x-9\implies \boxed{y=\cfrac{9}{2}x-6}[/tex]

now as far as the parallel line

keeping in mind that parallel lines have exactly the same slope, so we're really looking for the equation of a line whose slope is -2/9 and passes through (2 , 3)

[tex](\stackrel{x_1}{2}~,~\stackrel{y_1}{3})\qquad \qquad \stackrel{slope}{m}\implies -\cfrac{2}{9} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{-\cfrac{2}{9}}(x-\stackrel{x_1}{2}) \\\\\\ y-3=-\cfrac{2}{9}x+\cfrac{4}{9}\implies y=-\cfrac{2}{9}x+\cfrac{4}{9}+3\implies \boxed{y=-\cfrac{2}{9}x+\cfrac{31}{9}}[/tex]

Step-by-step explanation:

7 divided by 3.5 is 2

so when we add to the function outside of the parentheses of (x)^3, we are moving the graph in the up down direction so it would look like x^3 but shifted up 2 units. the way to easily know which one it is, plug in zero for x in the original and 0^3 is zero so we know the original fuction will go through the origin so the function who's center is is only shifted up (because it's positive 2) two units so graph 1

note: the reason i know that what looks like a center point is actually at the origin is because f(x)= x^3 is a very famous graph that you should know the shape of :)

Solution:

Step-by step calculations:

Combine like terms and simplify:

Subtract 126 both sides:

Divide 2 both sides:

This means that one angle is 27°. Let's find the other angle.

Finding the other angle:

Thus, the measure of the angles are 27° and 153°.

Answer:

27° and 153°

Step-by-step explanation:

Let "x" represent the angle.

We know that supplementary angles must add up to 180 degrees.

First, let's set up an expression for the supplement of the angle "x":

x+126

Now, let's use this information to set up an equation:

[tex]x+x+126=180[/tex]

Combine like terms:

[tex]2x+126=180[/tex]

Subtract 126 from both sides:

[tex]2x=54[/tex]

Divide both sides by 2

[tex]x=27[/tex]

The supplement would be:

[tex]x+126=27+126=153[/tex]

Therefore the measures of the two angles are:

27° and 153°

Answer: here

Step-by-step explanation:

The answer comes from the derivation of a straight line model for the cost vs students. Note that the change in cost of 145-135.50 = 9.50 for an increase of students from 25 to 30. The ratio of change of cost to change of students = 9.50/5 = 1.9 and becomes the slope coefficient "m" in the formula y= mx + b. y = the total cost, mx becomes the variable cost and b becomes the fixed cost. To find b, use the data point given where the total cost = $135.50 when the students = 25, or 135.50 = 1.9*25 +b. Solving for b yields $ 88. Note that the other data point is where the total cost is $145 for students = 30. Using the new total cost equation shows that 30*1.9+88= 145 thus verifying the math model works for the data points provided.

Answer:

7/25

Step-by-step explanation:

because its .28

The greatest between the 25% or [tex]\frac{7}{25}[/tex] should be considered as the [tex]\frac{7}{25}[/tex] because it is 28%.

Since one percentage i.e. 25% and one fraction i.e. [tex]\frac{7}{25}[/tex]

We need to determine greater between these two

So the fraction in percentage could be 28%

So we can say that the fraction should be bigger.

hence, The greatest between the 25% or [tex]\frac{7}{25}[/tex] should be considered as the [tex]\frac{7}{25}[/tex] because it is 28%.

Answer:

The angle is 112 degrees and the supplement is 68 degrees.

Step-by-step explanation:

Let the angle’s measure be represented by x and the supplement’s measure be represented by y. Since supplementary angles add to 180 degrees, x + y = 180.

Since the supplement is 44 degrees less than the angle,

y + 44 = x

We can substitute y + 44 = x for x in the first equation, since they are equivalent.

y + 44 + y = 180

2y + 44 = 180

2y = 136

y = 68

Substitute 68 for y in one of the original equations and solve.

68 + 44 = x

x = 112
