Hope it make sense :-)

Answer:

Growth factor = 5

Step-by-step explanation:

Given

[tex]y = 1.5(0.5)^x[/tex]

Required

Determine the growth factor

An exponential function is represented as: [tex]y = ab^x[/tex]

Where b is the growth factor

By comparing: [tex]y = ab^x[/tex] to [tex]y = 1.5(0.5)^x[/tex]

[tex]b = 0.5[/tex]

Hence, the growth factor is 5

Answer:

$2.50X > $25

Step-by-step explanation:

the cost times the unknown will be less or equal to$25

The inequality function to  represent the relationship between the amount of money should be considered as the $2.50X > $25.

Since

Jinan has $25 dollars to spend on drinks for the class party.

And, A case of drinks cost $2.50.

So here the inequality function should be $2.50X > $25

Here the cost should be less or equivalent to 25.

Answer:

About 31 days

Step-by-step explanation:

Since he already has $125, you can subtract that amount from how much he needs to earn. $400 - $125 = $275 that he must earn.

Divide the remaining amount by how much he earns a day to find the number of days he must work to reach his goal.

$275 ÷ $9 ≈ 30.5 (I got 30.5 repeating). I rounded up to 31 days.

Answer:

The equation of the line is:

[tex]y -1= 5(x - 2)[/tex]

Step-by-step explanation:

Given

Pass through [tex](2,-1)[/tex]

Parallel to: [tex]y= 5x - 2[/tex]

Required

Determine the equation in point slope form

An equation has a general form:

[tex]y = mx + c[/tex]

Where:

[tex]m = slope[/tex]

Compare: [tex]y = mx + c[/tex] to [tex]y= 5x - 2[/tex]

we have:

[tex]m = 5[/tex]

Since the line is parallel to [tex]y= 5x - 2[/tex], then they have the same slope of 5

The line equation is then calculated using:

[tex]y -y_1= m(x - x_1)[/tex]

Where

[tex]m = 5[/tex]

[tex](x_1,y_1) =[/tex] [tex](2,-1)[/tex]

So, we have:

[tex]y -1= 5(x - 2)[/tex]

Answer:

16.66%

Step-by-step explanation:

175-150= 25/week increase

now to find what that represents as a percent:

175/150 = x/100  cross multiply

150x = 17500 divide both sides by 150

x = 116.66 *** but!!! we now have to remember we started with a "full" salary - this is an increase.

So, 166.66 - 100 = 16.66

16.66%  Are you asked to round your answer to a whole percent? Of so, you might round that to a 17% increase (though this is not as precise as the decimal).

Answer:

C. 21 pennants

Step-by-step explanation:

35-28=7

7 divided by 1/3= 21/1 or 21

The number of pennants that can be made is given by equation A = 49 pennants

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the number of pennants required be represented as A

The amount of fabric bought by students = 28 yards

The amount of fabric required by each pennant = 1/3 yards

The total number of pennants made by students = 35 pennants

So , the number of pennants that can be made is N

N ( 1 / 3 ) = 28 be equation (1)

Multiply by 3 on both sides , we get

N = 84 pennants

So , the remaining number of pennants A = N - number of pennants made by students

On simplifying the equation , we get

The remaining number of pennants A = 84 - 45

The remaining number of pennants A = 49 pennants

Hence , the number of pennants is 49
