5. What are the solutions to the equation (x - 1)(x + 2) = -2?

Answer:

y=2.5x - Proportional  

y= x - 4 - Not Proportional  

Step-by-step explanation:

A linear function that is proportional is in the form y =kx (k is the constant of variation) and passes the origin.

The first equation given is in this form (2.5 is the constant) and it passes through the origin. It is proportional.

However, the second one is not proportional is it does not pass the orgin and it's not in y=kx form.

Hope this helps.

Answer:

negative 0.75

Answer:

[tex] x_{1} = \frac{ - \sqrt{89 + 3} }{4} [/tex]

[tex] x_{2} = \frac{ \sqrt{89 + 3} }{4} [/tex]

Step-by-step explanation:

1) Move the variable to the left

2) Divide both sides

3) Add the same value to both sides

4) Add 9/16 to the expression

5) Add 9/16 to the right-hand side

6) Recalculate then solve

Answer:

x^2 - 4x - 12

Step-by-step explanation:

Using FOIL (first, outside, inside, last), multiply each term in the order:

you should get ---> x^2 + 2x - 6x - 12

now, add like terms

you should get ---> x^2 - 4x - 12

Answer:

32 degrees

Step-by-step explanation:

lets assume a point K on top of M and giving the the measure of <KMN  = 90 degree.

let LMP be x

KML = 90 - 79 = 11

x =  90-11-47 = 32

thus, <LMP is 32 degrees

Longitudinal study

Step-by-step explanation:

Information is collected over extended periods of time in a longitudinal study, but in cross-sectional, natural observation, and experimental studies, information is collected over short periods of time or in one time only. Based on the choices given, this type of study would be a longitudinal study.

Answer:

14%

Step-by-step explanation:

So if we have 4 Year 11 pupils out of a total of 29 pupils at a football club, the fraction for that would be 4/29, if we convert 4/29 into a decimal number we get 0.13793103448, so we round this number up to the nearest 1 decimal place, and that would be 0.14 which equals 14%. Hope this helps.

The graph must pass through the y-axis at y = -4 with a positive slope of 3

Given the expression

Write the given equation in standard form to have:

7x+y=10x-4.

y = 10x - 7x - 4

y = 3x - 4

From the equation, the slope is 3 and the y-intercept is -4

The graph must pass through the y-axis at y = -4 with a positive slope of 3.

Answer:

20.

Step-by-step explanation:

We need to setup a proportion. We want the result to be 40% out of 50, meaning that we are solving for x:

4/10=x/50.

Cross-multiplying, we have 200 = 10x, and x = 20.

Answer:

See below

Step-by-step explanation:

As x approaches negative infinity, h(x) approaches negative infinity

As x approaches positive infinity, h(x) approaches negative infinity

I've attached a graph to show why these two are true. Remember that in an absolute value function, the result is always positive. However, because there's a negative constant multiplying the absolute value function, this flips the graph over the x-axis and the result is now always negative. In other words, no matter how big or small x is, y will always get smaller.

Using a linear function, it is found that the estimated French score is of 38.1875.

A linear function has the following format:

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

In which:

Searching the problem on the internet, it is found that two points of the line of best-fit are: (10,65) and (90,26).

The slope is given by change in the output divided by the change in the input, hence:

[tex]m = \frac{26 - 65}{90 - 10} = -0.4875[/tex]

Then:

[tex]y = -0.4875x + b[/tex]

Point (10,65) means that when [tex]x = 10, y = 65[/tex], and this is used to find b.

[tex]y = -0.4875x + b[/tex]

[tex]65 = -0.4875(10) + b[/tex]

[tex]b = 69.875[/tex]

Hence:

[tex]y = -0.4875x + 69.875[/tex]

For a student who got 65 in math, x = 65, and hence:

[tex]y = -0.4875(65) + 69.875 = 38.1875[/tex]

The estimated French score is of 38.1875.
