PLS HELP I HAVE TRIED THREE TIMES. GEOMETRY SOLVE WITH A VENN DIAGRAM

Step-by-step explanation:

Here is Slope-Intercept Form for a line: y=mx+b

m is the slope

b is the y intercept

The y intercept is basically the point on the y axis where the line touches.

I will do #3 for you.

Let's first look for the y intercept. We can see that the line touches the y axis at -4, so that's it.

Let's put it into our equation, plugging in -4 for b. This is what we have so far: y=mx-4

To complete this equation, we still need to find the slope, m.

To find it, look at the point where the y intercept is, and count how many units you need to go up or down the y axis, and then right or left the x axis to get to another point on the line. The slope is equal to the change in y ÷ the change in x.

So we see that there's another point on (-3, -2), so let's try to get there from the y intercept.

We need to move two units up and 3 to the left.

In terms of y, we went up +2, and in terms of x, we went down -3

So our slope is 2/-3 or -2/3.

Now that we have our slope (m) and y intercept (b), we can plug it into out Slope-Intercept Equation, plugging in -2/3 for m:

y=-2/3x-4.

We don't need to find x or y. This is our answer for 3. Using the same method, you should be able to find the equations for the rest of the graphs. Good luck.

Answer:

a^n = -6n + 32

Step-by-step explanation:

32 - 6 = 26

26 - 6 = 32 - 6.2 = 20

20 - 6 = 32 - 6.3 = 14

-> a^n = -6n + 32

Answer:

Trinomial: (2x² – 5x) + (4x – 10)

GCF: x (2x – 5) + 2 (2x – 5)

Step-by-step explanation:

2x² – x – 10

The equation above can be factorised as follow:

2x² – x – 10

Multiply the first term (i.e 2x²) and the last term (i.e –10) together.

2x² × (–10) = –20x²

Find two factors of –20x² such that when we add them together, it will result to the 2nd term in the equation (i.e –x).

The factors are 4x and –5x.

Next, replace –x in the equation above with 4x and –5x. This is illustrated below:

2x² – x – 10

2x² – 5x + 4x – 10

Next, factorise

2x² – 5x + 4x – 10

Trinomial: (2x² – 5x) + (4x – 10)

GCF: x (2x – 5) + 2 (2x – 5)

[tex] \frac{11}{25} \times 100 = \frac{11}{25} \times 25 \times 4 \\ [/tex]

[tex] = 11 \times 4 = 44 \: \: percent[/tex]

So %44 of your class students chose pizza.

The percentage of the class chose pizza = 44%

"It is a number or ratio that can be expressed as a fraction of 100."

For given example,

Total number of students = 25

the number of students who chose pizza as their favorite food = 11

So, the percentage of the class chose pizza would be,

⇒ (11/25) × 100 = 44%

Answer:

20:1

Step-by-step explanation:

It is given that,

Input voltage = 260 volt

Output voltage = 13 volt

We need to find the ratio of the number of input wire coils to output wire coils on the transformer.​

For a step-down transformer,

[tex]\dfrac{V_i}{V_o}=\dfrac{N_P}{N_S}\\\\\dfrac{N_P}{N_S}=\dfrac{260}{13}\\\\=\dfrac{20}{1}[/tex]

Hence, the required ratio is 20:1.

Step-by-step explanation:

Answer: f (-2) 5

Your welcome

A function is a relation between two variables where one variable is the set of inputs that gives the other variables as output.

The value of the function at x = -2 is 5.

The domain of the function = 5.

The range of the function = -2.

A function is a relation between a set of inputs called domains and it has one output called the range.

Example:

f(x) = x + 2

At x = 2,

f(2) = 2 + 2 = 4

Domain = 2

Range = 4

We have,

f(x) = x² + 4x + 9

We need to find the value of the function at x = -2.

Substitute x = -2 in f(x).

f (-2) = (-2)² + 4x(-2) + 9

f (-2) = 4 - 8 + 9

f (-2) = 5

Thus the value of the function at x = -2 is 5.

Answer:The answer is 1/x^12y

Step-by-step explanation:

Answer:

This expression is not factorable with rational numbers.

Step-by-step explanation:

The way factoring works, you just want to get it to its smallest form possible. To do that you would divide the entire problem by the Least Common Multiple.

This problem does not have a least common multiple. The LCM of 16 and 64 is 16 but x^2 does not have a number in front. 16k and 64 can be factored but in order to factor the entire problem, x^2 would need to have a number in front that made it divisible by a common multiple of 16 and 64.

Say if the problem was 2x^2+16k+64, you could divide the entire problem by 2. Your answer would be:

It is important to note that when you are factoring, never divide any exponents.

The way to check your work when factoring is to distribute the number outside of the parentheses. So in the example I just gave, you'd multiply everything in the parentheses, except the exponent, by 2. Which will give you the original 2x^2+16k+64.

Whatever number you factor out and end up putting outside your parentheses, should multiply back into the parentheses to give you the original problem. If it doesn't, then the factoring was done incorrectly.

Your answer should include parentheses.

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

For this situation we will use this equation:

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

This lets us find the slope from a set of points (m being the slope of course), with each one representing a coordinate from our set. (e.g. 7 could be [tex]y_{2}[/tex])

First let's define which coordinates will represent each:

(-1,3): [tex]x_{1} ,y_{1}[/tex]

(5,7): [tex]x_{2} ,y_{2}[/tex]

Now that we have this, we can fill in our coordinates: [tex]m = \frac{7-3}{5-(-1)}[/tex]

Next we simplify: [tex]m = \frac{4}{5+1}[/tex] (double negative = positive)

And simplify some more: [tex]m = \frac{4}{6}[/tex]

Finally, we find the GCF (greatest common factor) of 4 and 6, which is 2, and divide by that to further simplify the fraction: [tex]m = \frac{2}{3}[/tex]

Therefore, the slope of the line that passes through the points (-1,3) and (5,7) is [tex]\frac{2}{3}[/tex].
