Answer:

12w + 8d = 100

Step-by-step explanation:

Given:

Price of wall calendars = $12

Price of desk calendars = $8

Total amount pay = $100

Computation:

w = wall calendars

d = desk calendars

So,

Price of wall calendars(w) + Price of desk calendars(d) = Total amount

12w + 8d = 100

Answer:

2/3 =x

Step-by-step explanation:

f(x) = 3x - 2

Let f(x) =0

0 = 3x-2

Add 2 to each side

2 = 3x-2+2

2 =3x

Divide by 3

2/3 =3x/3

2/3 =x

Answer:

f(x)=3x-2

0=3x-2

2=3x

2/3=x

x=2/3

Positive because you have two negatives. (3)(-25) is a negative number, (7)(-24) is also a negative number. Negative * negative is positive.

First option is correct

Answer:

First one

Step-by-step explanation:

(3)(−25): product is negative (-75)

(7)(−24): product is negative (-168)

Multiply these values, which are negative, gives you a positive real number (12600) because two negatives gives you a positive

you can also flip the position the the fractions are in

[tex]\frac{4}{6}q + \frac{7}{12}[/tex]  or [tex]\frac{2}{3}q + \frac{7}{12}[/tex]  

Step-by-step explanation:

[tex]\frac{11}{12} - \frac{1}{6} q + \frac{5}{6} q - \frac{1}{3}[/tex]

first find the like terms

[tex]\frac{11}{12}- \frac{1}{3}[/tex]

       ↑

times it by [tex]\frac{4}{4}[/tex] to get [tex]\frac{4}{12}[/tex] to make the subtraction easier.

[tex]\frac{11}{12}- \frac{4}{12}[/tex]

and

[tex]\frac{5}{6} q} - \frac{1}{6} q[/tex]

now that they all have the same denominator,

subtract

[tex]\frac{11}{12}- \frac{4}{12}[/tex] = [tex]\frac{7}{12}[/tex]

and

[tex]\frac{5}{6} q} - \frac{1}{6} q[/tex] = [tex]\frac{4}{6} q[/tex]

add them together to get

[tex]\frac{7}{12} + \frac{4}{6}q[/tex]

you can simplify 4/6q to 2/3q

The solution of the expression [tex]\dfrac{11}{12} - \dfrac{1}{6}q + \dfrac{5}{6}q - \dfrac{1}{3}[/tex] by combining like terms is [tex]\dfrac{7}{12} + \dfrac{2}{2}q[/tex].

Used the concept of an equation that states,

A mathematical expression is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.

Given that the expression is,

[tex]\dfrac{11}{12} - \dfrac{1}{6}q + \dfrac{5}{6}q - \dfrac{1}{3}[/tex]

Now combine like terms in the equation and solve as

[tex]\dfrac{11}{12} - \dfrac{1}{6}q + \dfrac{5}{6}q - \dfrac{1}{3}[/tex]

[tex]\dfrac{11}{12} - \dfrac{1}{3}- \dfrac{1}{6}q + \dfrac{5}{6}q[/tex]

[tex]\dfrac{(11 - 4)}{12} + \dfrac{5}{6}q- \dfrac{1}{6}q[/tex]

[tex]\dfrac{(11 - 4)}{12} + \dfrac{(5 - 1)}{6}q[/tex]

[tex]\dfrac{(7)}{12} + \dfrac{(4)}{6}q[/tex]

[tex]\dfrac{7}{12} + \dfrac{2}{2}q[/tex]

Therefore, the solution is [tex]\dfrac{7}{12} + \dfrac{2}{2}q[/tex].

Step-by-step explanation:

Answer:

A) The graph represents the function h(x) = 1.5x + 3

D)The plant grows about 1.5 inches each week.

Step-by-step explanation:

The following statements are true -

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have Kay created a linear graph to track the height in inches [h] of a pepper plant over a number of weeks [x]. The plant's height was 3 inches when purchased.

Since the slope of the graph is 1.5 inches. We can write the equation of the graph as -

y = 1.5x + 3

This also shows, the plant grows about 1.5 inches each week.

Therefore, the following statements are true -

Answer: 4.2495 feets

Step-by-step explanation:

Given the following :

Rate of change (speed) when rock hits the lake surface = - 3in/s

Distance or depth after 5 seconds :

Distance = rate of change * time

Distance = (- 3 in/s × 5) = - 15 inches

1 inch = 0.0833 feet

15 inches = (-15 * 0.0833) = - 1.2495 feets

Distance between Lisa's hand and lake surface = 3 feets :

Distance between Lisa's hand and rock after 5 seconds :

(3 feets + 1.2495 feets) = 4.2495 feets

Answer:

You may be asked to "determine algebraically" whether a function is even or odd. To do this, you take the function and plug –x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (–x) = f (x), so all of the signs are the same), then the function is even.

The median is 120, The lower quartile is 112 and The upper quartile is 140

and  interquartile range is 28.

The difference between the third and first quartiles is referred to as the interquartile range. Quartiles are the parceled values that partition the entire series into 4 equivalent parts. There are then three quartiles. The lower quartile is represented by Q1, the second quartile is represented by Q2, and the third quartile is represented by Q3, which is the upper quartile. As a result, the difference between the upper and lower quartiles constitutes the interquartile range.

Given data

115, 120, 118, 104, 109, 148, 135, 141, 139

arrange series in ascending order,

104, 109, 115, 118, 120, 135, 139, 141, 148

the middle term of series is 120

median = 120

for lower Quartile Q₁ = (109 + 115)/2 = 112

for upper Quartile Q₃ = (139 + 141)/2 = 140

interquartile range = Q₃ - Q₁  = 140 - 112 = 28

Hence the median = 120,  lower quartile = 112,  upper quartile = 140 and

interquartile range = 28.

Answer:

The average rate of change of the function over the given interval is -6

Step-by-step explanation:

The function we want to find its average rate of change is;

F(x) = 17 - x^2

Mathematically, the average rate of change of a function F(x) over an interval (a,b) can be calculated as;

{F(b) - F(a)}/(b-a)

According to this question, a = 1 and b = 5

F(a) = F(1) = 17 -(1)^2 = 17 -1 = 16

F(b) = F(5) = 17 - 5^2 = 17-25 = -8

So making the substitution; we have

(-8)-16/(5-1) = -24/4 = -6

Answer:

[tex]BC=12\\x=6\\AC=24[/tex]

Step-by-step explanation:

Lines AB and BC have two smaller lines in them, meaning that they are of the same length. Thus, BC is 12.

AB + BC = AC

Substitute in values:

[tex]12+12=4x[/tex]

Add the numbers and swap sides:

[tex]4x=24[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{24}{4}[/tex]

AC is [tex]4x=4\times6=24[/tex]

Step-by-step explanation:

y=x-1 2x-3y=-1

y=6x-11 -2x-3y=7

y=-5x-17 -3x-3y=3

y=5x-7 -3x-2y=-12

To solve a system of  2  variables, only  2  equations are required. Choose the first two equations containing the variables in the system.

y = x − 1 2 x − 3 y = − 1

Subtract  x  from both sides of the equation.

y − x = − 1 2 x − 3 y = − 1

Reorder the polynomial.

− x + y = − 1 2 x − 3 y = − 1

Multiply each equation by the value that makes the coefficients of  x  opposite.

( 2 ) ⋅ ( − x + y ) = ( 2 ) ( − 1 ) 2 x − 3 y = − 1

Simplify.

− 2 x + 2 y = − 2 2 x − 3 y = − 1

Add the two equations together to eliminate  x  from the system.

− 2 x + 2 y = − 2 + 2 x − 3 y = − 1 − y = − 3

Multiply each term in  − y = − 3  by  − 1

y = 3

Substitute the value found for  y  into one of the original equations, then solve for  x .

x = 4

The solution to the independent system of equations can be represented as a point.

( 4 , 3 )

The result can be shown in multiple forms.

Answer:

Jenkins: 25 hours Alexanders: 20 hours

Step-by-step explanation:

To solve this problem we need to set up two equations. We know the rates of each sprinkler's output and how much total water was output. We know how many hours the sprinklers were on. We are looking for how long each sprinkler was used.

We can make a represent hours because we know the rate of sprinkler's output is per hour.

25a+40b=1425

a+b=45

Now to solve this system of equations we need to isolate a variable on one equation to plug into the other.

a+b=45

a=45-b

Now we can plug this in for a in the other equation.

25a+40b=1425

25(45-b)+40b=1425

Distribute 25 into the parenthesis.

1125-25b+40b=1425

1125+15b=1425

15b=300

b=20

Now we know that the Alexander family used their sprinklers for 20 hours. We can plug this back into the other equation to find b.

a+b=45

a+20=45

a=25

The Jenkins used the sprinklers for 25 hours, and the Alexanders used them for 20 hours.

The difference of the polynomials given is  -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵

Given are two polynomials are :

(-2x³y² + 4x²y3³ - 3xy⁴) and (6x⁴y - 5x²y³ - y⁵)

We need to subtract the polynomials and find the difference.

(-2x³y² + 4x²y3³ - 3xy⁴) - (6x⁴y - 5x²y³ - y⁵)

By multiplying the signs into the brackets

= -2x³y² + 4x²y3³ - 3xy⁴ - 6x⁴y + 5x²y³ + y⁵

Grouping the like terms, we get

= -2x³y² + (4x²y3³ + 5x²y³) - 3xy⁴ - 6x⁴y + y⁵

= -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵

Therefore, the difference between the polynomials is -2x³y² + 9x²y³ - 3xy⁴ - 6x⁴y + y⁵
