Answer:

It is not linear because it does not have a constant rate of change

Step-by-step explanation:

See attachment for Jordana's graph

From the attachment, it'll be observed that the graph has a curved line.

This means that the graph is not a linear and does not represent a linear function.

In functions, a linear representation has a constant slope (in other words, constant rate of change) while non linear representations do not.

So, since we've been able to establish that the graph is non linear, then we can conclude that the graph do not have a constant slope.

Base on the analysis above and from the list of given options, option (d) is correct.

Answer:

x = -3, x = 7

Step-by-step explanation:

( 5x + 15 ) ( x - 7 ) = 0

5x + 15 = 0

5x = -15

x = -3

x - 7 = 0

x = 7

Answer:

x=−3 or x=7

Step-by-step explanation:

(5x+15)(x-7)=0

5x2−20x−105=0

5(x+3)(x−7)=0

x+3=0 or x−7=0

x=−3 or x=7

Answer:

cos(52.5°)sin(7.5°)

sin(52.5°)sin(7.5°)

cos(52.5°)cos(7.5°)

sin(52.5°)cos(7.5°)

In increasing order , the expressions are written as follows , cos(52.5°)sin(7.5°) , sin(52.5°)sin(7.5°) , cos(52.5°)cos(7.5°) , sin(52.5°)cos(7.5°).

Statements that have more than one term and a variable is connected to another variable by a mathematical operator are called Expressions.

The expression given are

cos(52.5°)cos(7.5°)

sin(52.5°)cos(7.5°)

sin(52.5°)sin(7.5°)

cos(52.5°)sin(7.5°)

To arrange them into increasing order , the value of it has to be determined.

cos(52.5°)cos(7.5°) = 0.6088 * 0.9914 = 0.6036

sin(52.5°)cos(7.5°)= 0.7933*0.9914 = 0.7865

sin(52.5°)sin(7.5°)= 0.7933*0.1305 = 0.1035

cos(52.5°)sin(7.5°)= 0.6088*0.1305= 0.07945

Therefore in Increasing order , the expressions are written as follows , cos(52.5°)sin(7.5°) , sin(52.5°)sin(7.5°) , cos(52.5°)cos(7.5°) , sin(52.5°)cos(7.5°).

Step-by-step explanation:

Easy, because the 'mean' is also called the 'average'.

To find the average of a list:

1). Add up all the items on the list.

then

2). Divide the sum by the number of items on the list.

For your list:

3) 5+12+4+8+7+10+12=58

4) There are 7 students so we divide, 58/7=8.28

Answer:

It would take 28 months for Gym Strong to be a better buy.

Step-by-step explanation:

There are two possible options for gyms to choose from:

Gym Strong charges $350 plus $15 a month

Gym Fit charges $100 plus $24 a month.

Since Gym Strong charges less per month but has a higher initial fee, there will be some time when it will be a cheaper option than Gym Fit.

Let's solve this by analyzing the differences in fixed fees and monthly fees.

The difference of fixed fees is $350 - $100 = $250

The difference on monthly fees is $24 - $15 = $9

Both gyms will charge the same total fees when have passed 250/9 = 27.7 months. Since the number of months is a whole number, we round up.

It would take 28 months for Gym Strong to be a better buy.

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

0.2(4x + 10) - 0.9x = 0.2(x - 6) + 12.2

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 5 does indeed equal 5.

∴ x = -30 is the solution to the equation.

Step-by-step explanation:

y = -3x² + 12x - 33

y = -3[x² - 4x + 11]

y = -3[(x - 2)² + 7]

Since the coefficient of x² is negative, the curve concaves downwards and has an absolute maximum value. This happens when x = 2, y = -21.

Therefore the correct option is A.

Answer:

n = 2

Step-by-step explanation:

0.5n - 2 - 3 = 3 - 2n -3

0.5n + 2n = 2 + 3 + 3 -3

2.5n = 5

n = 2

Answer:

Step-by-step explanation:

0.5n - 2 - 3 = 3 - 2n - 3

Solving like terms

0.5n - 5 = - 2n

-5 = - 2n - 0.5n

-5 = - 2.5n

-5/-2.5 = n

2 = n

Answer:

The minimum monthly income required by the lender is $5214.30

Step-by-step explanation:

Here, we want to calculate the minimum monthly income required by the lender

From the question, we have that the monthly payment must not exceed 28% of the buyer’s monthly income

So in this case, let the monthly income be x

So therefore;

28% of x = 1460

Thus;

28/100 * x = 1460

28x = 100 * 1460

x = (100 * 1460)/28

x = 5214.30
