h(x), g(x), f(x)

Step-by-step explanation:

The y-intercept of h(x) = -1        (0, -1)

The y-intercept of g(x) = 1          (0,1)

The y-intercept of f(x) = 2          (0, 2)

Answer:

$17.5 differnce

Step-by-step explanation:

20% tip on is $57.49

20% tip off is $39.99

tip on vs off when a tip is on means its

First difference,

[tex]\Delta_{1} = a_{2} - a_{1} = 3 - 1 = 2 = 1 + 1[/tex]

Second difference,

[tex]\Delta_{2} = a_{3} - a_{2} = 6 - 3 = 3 = 2 + 1[/tex]

Third difference,

[tex]\Delta_{3} = a_{4} - a_{3} = 10 - 6 = 4 = 3 + 1[/tex]

And so on.

Assuming the pattern holds on, we see that

i-th difference,

[tex]\Delta_{i} = a_{i + 1} - a_{i} = i + 1[/tex]

[tex]\implies a_{i + 1} = a_{i} + i + 1[/tex]

Then, nth term is,

[tex]\implies a_{n} = a_{n - 1} + n[/tex]

[tex]= a_{n - 2}+ (n + (n - 1))[/tex]

[tex]= a_{n - 3} + (n + (n - 1) +(n - 2))[/tex]

[tex]= a_{n - (n - 1)} + \sum \limits^{n - 2}_{k = 0}(n - k)[/tex]

[tex]= a_1 + \sum \limits^{n - 2}_{k = 0}n- \sum \limits^{n - 2}_{k = 0}k[/tex]

[tex]= a_1 +n(n -2 + 1 )- \frac{1}{2} (n - 2)(n - 1)[/tex]

[tex]= a_1 +n(n -1 )- \frac{1}{2} (n - 2)(n - 1)[/tex]

[tex]= a_1 +(n -1 )(n- \frac{1}{2} (n - 2))[/tex]

[tex]= a_1 + \frac{1}{2} (n -1 )(2n- n + 2)[/tex]

[tex]= a_1 + \frac{1}{2} (n -1 )(n + 2)[/tex]

[tex]\implies a_{n} = 1 + \frac{1}{2} (n -1 )(n + 2)[/tex]

Now, the 21st term in the sequence is,

[tex]\implies a_{21} = 1 + \frac{1}{2} (21 -1 )(21 + 2)[/tex]

[tex]= 1 + \frac{1}{2} \times 20 \times 23[/tex]

[tex]= 231[/tex]

Answer:

38 degrees, see below :)

Step-by-step explanation:

Hello! :)

So, we can use the Base Angles theorem to say the angle with 62 degrees is equal to angle 1.

Now we know angle 1 = 62 degrees.

Next, we can use the exterior angles theorem to say that angle 3 is the sum of the remote interior angles of the triangle so:

angle 3 = 62 + angle 1

= 62 + 62

= 124

Now we know angle 3 = 124 degrees

We can find angle 4 by subtracting 18 degrees and angle 3 from 180 degrees because we know that they all have to add up to 180 so:

angle 4 = 180 - (18 + 124)

= 180 - 142

= 38 degrees.

Step-by-step explanation:

Alternate interior angles measure same as per their property:

Answer:

x³ + x²y - 2xy² - xy + y²

Step-by-step explanation:

Given

(x - y)(x² + 2xy - y)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x² + 2xy - y) - y(x² + 2xy - y) ← distribute both parenthesis

= x³ + 2x²y - xy - x²y - 2xy² + y² ← collect like terms

= x³ + x²y - 2xy² - xy + y²

Answer:

as below

Step-by-step explanation:

(x-y)([tex]x^{2}[/tex]+2xy-y)

Answer:

[tex]9x + 4 - 3y^2[/tex]

Step-by-step explanation:

Given

[tex]5x+4x - 1+3 - 7y^2 +2+4y^2[/tex]

Required

Simplify

[tex]5x+4x - 1+3 - 7y^2 +2+4y^2[/tex]

Collect Like Terms

[tex]5x+4x - 1+3 +2+4y^2- 7y^2[/tex]

Simplify like terms

[tex]9x + 4 - 3y^2[/tex]

Hence,

[tex]5x+4x - 1+3 - 7y^2 +2+4y^2[/tex] [tex]= 9x + 4 - 3y^2[/tex]

Answer:

[tex]7.96 *10^8kg[/tex]

Step-by-step explanation:

Given

[tex]Eiffel = 9.16 * 10^6\ kg[/tex]

[tex]Golden\ Gate =8.05 * 10^8kg[/tex]

Required

Determine the difference in mass

This is calculated by subtracting the mass of Eiffel tower from the mass of Golden gate bridge

[tex]Difference = Golden\ Gate - Eiffel[/tex]

[tex]Difference = 8.05 * 10^8 - 9.16 * 10^6[/tex]

Express [tex]10^8[/tex] as [tex]10^6 * 10^2[/tex]

[tex]Difference = 8.05 * 10^2*10^6 - 9.16 * 10^6[/tex]

Express [tex]10^2[/tex] as [tex]100[/tex]

[tex]Difference = 8.05 * 100*10^6 - 9.16 * 10^6[/tex]

[tex]Difference = 805 *10^6 - 9.16 * 10^6[/tex]

Factorize:

[tex]Difference = (805- 9.16) * 10^6[/tex]

[tex]Difference = 795.84 * 10^6[/tex]

Factorize the decimal number

[tex]Difference = 7.9584 *10^2 * 10^6[/tex]

[tex]Difference = 7.9584 *10^8[/tex]

Approximate:

[tex]Difference = 7.96 *10^8[/tex]

Step-by-step explanation:

The graph for the given equations is plotted in graph below.

The given equation is y=3/2 x+1.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

Graph the line using the slope and y-intercept, or two points.

Slope: 3/2

y-intercept: (0,1)

Plot (0, 1) and (2, 4)

Therefore, the graph for the given equations is plotted in graph below.

Answer:

A. Genevieve

B. Sierra

Step-by-step explanation:

Genevieve uses 5 balloons per animal, but Sierra uses 6. We can find this by subtracting 360 from 440 (which gets us 80). To find the unit rate, we divide 20 into 80 (the amount of balloons used when she made 20 animals), and we get 4. So, Sierra uses 4 balloons per animal.

Since Genevieve uses more balloons per animal and started with less balloons than Sierra (she started with 425, versus Sierra, who started with 440), Sierra will have made more animals by the end of the day.

I hope this helps!

Step-by-step explanation:

Answer:

11

Step-by-step explanation:

first solve 5-2x=21

subtract 5 on both sides to get

-2x=16, then divide -2 on both sides to get

x= -8 then

3-(-8) which is 3+8=11

Answer:

y = -3

Step-by-step explanation:

Given the expression 7-(3.1-0.1у)=3-0.2у

We are to find the value of y as shown

7-(3.1-0.1у)=3-0.2у

Open the parenthesis

7-3.1+0.1y= 3-0.2y

3.9+0.1y = 3-0.2y

Collect like terms

0.1y+0.2y= 3-3.9

0.3y = -0.9

y = -0.9/0.3

y = -3

Hence the value of y is -3
