What is the y-intercept of the line 3x2y=-18

Answer:

8, 18 and 36 respectively.

sum=54

1st number=x

2nd number=x+10

3rd number =2(x+10)=2x+20

x+x+10+2x+20=54

put the liketerms together

x+x+2x=54-10-20

4x=24

divide both sides by 4 to get

x=8

Input the other values

Answer:

The answer is C; y=x+2

Step-by-step explanation:

y=mx+b (3, 5)

5=1(3)+b

5=3+b

subtract 3 from both sides of the equation

2=b

equation; y=mx+b

                y=x+2

Answer:

C. y = x + 2

Step-by-step explanation:

→You can figure this out by using the point-slope form:

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

[tex]y-5=1(x-3)[/tex]

→Distribute the 1 to (x - 3):

y - 5 = x - 3

→Add 5 to both sides:

y = x + 2

Answer:

Step-by-step explanation:

(2, 3) and (5, 6) are the endpoints of a line segment that is not parallel to either axis and does not intersect either axis.

An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y coordinate.

A line segment is a piece or a part of line having two end points.

Since, a line segment is parallel to the either one axis if its one coordinate point is zero, whether it's y or x.

So for not parallel to either axis and does not intersect either axis  we will choose those points which are not zero.

Therefore,

The coordinates of the end points of a line segment that is not parallel to either axis and does not intersect either axis will be (2, 3) and (5, 6).

Similarly, you can use any point using this concept like (7,9) ad (2,3) and many.

Answer: 76 ft2

Step-by-step explanation:

Perimeter = 2 side length +base length

40 = 2s +12

Solving for s:

40-12 =2s

28 =2s

28/2=s

14ft =side

Since the line which bisects and isosceles triangles is at a right angle to the base we can use the Pythagorean Theorem to find the height (see attachment)  

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (in this case 14) and a and b are the other sides. (Base divided by 2 is one side, the other side is the height)

Replacing with the values given:  

14^2= 6^2 + x^2

196 = 36 + x^2

196-36 = x^2

160 = x^2

√160 = x

x = 12.64 (height)

Area of an isosceles triangle = 1/2 x base x height  

A = 1/2 x 12 x 12.64 = 76 ft2

Answer:

[tex]n^2+5n+2[/tex]

Step-by-step explanation:

Given the sequence

8, 16, 26, 38, 52, 68, 86,...

The nth term of a quadratic sequence will take the form:

[tex]an^2+bn+c[/tex]

Step 1: Find the difference between each term

The differences are: 8,10,12,14,...

Step 2: Find the differences between the differences

We notice an addition of 2, so the second difference is 2.

Step 3:

Take the half of the second difference to obtain a.

2/2=1

Therefore: a=1

The sequence for now is: [tex]n^2+bn+c[/tex]

Step 4: Find [tex]T_n-n^2[/tex]

[tex]T_1=8, T_1-1^2=8-1=7\\T_2=16, T_2-2^2=16-4=12\\T_3=26, T_3-3^2=26-9=17[/tex]

We notice that [tex]T_n-n^2[/tex] forms a linear sequence 7,12,17

We can write this as 2+5n

Therefore, Our nth rule for the quadratic sequence is therefore: [tex]n^2+5n+2[/tex]

Answer:

EF = 34, FG = 25

Step-by-step explanation:

EG is the total of the two smaller segments, EF and FG.

Therefore:

8x-14 + 4x+1 = EG

8x-14 + 4x+1 = 59

Now we can solve this equation.

8x-14 + 4x+1 = 59

12x-13 = 59

12x = 72

x = 6

Now, we can plug in the values of x into the expressions for the lengths of EF and FG:

EF

8x-14

8(6)-14

48-14

= 34

FG

4x+1

4(6)+1

Answer:

Since, company A charge of $423.5 is less than company B charge of $450

Hence,

Company A should be hired to get the better deal.

Step-by-step explanation:

Dimension of room: 11 * 14 foot

Area of rectangle is given by length * width

Thus,

area of room using above formula = 11*14 square foot = 154 square foot

For company A

charge  for 1 square foot = $2.75

Charge for room = charge  for 1 square foot * area of room

                           = 2.75 * 154 = 423.5

Thus, Total money charged by company  A as calculated above is $423.5

Given,

company B charges $450 per room

Since, company A charge of $423.5 is less than company B charge of $450

Hence,

Company A should be hired to get the better deal.

Step-by-step explanation

Here, we want to select what is true of the function.

The correct answer is that the variable x represents the independent variable

It represents the independent variable because the values of x does not depend on the values of g(x). In fact, the value of g(x) are dependent on the values gotten through the substitution of the different values of x into the equation.

Thus, we can confidently say that the function g(x) is the dependent variable as its values depend on the value for that x

Answer:

equation for the new circle is;

(x - 8)² + y² = 36

Step-by-step explanation:

There are two types of translations and they are translation horizontally and vertically. Combining both of them in the context of this question, to translate a circle 6 units to the right and 4 units up, we take our equation,

(x - 2)² + (y + 4)² = 36 and subtract 6 from the x - term and 4 from the y - term to get the equation of the new circle.

This gives us;

(x - 2 - 6)² + (y + 4 - 4)² = 36

This gives;

(x - 8)² + y² = 36

Given: bacteria to increase from 2000 to  50,000

To find: Number of days that a culture of bacteria will take to increase from 2000 to  50,000

Solution:

The growth of bacteria is represented by the equation: [tex]P(t)=P_0e^{kt}[/tex]

Here, t denotes time, k denotes growth rate and [tex]P_0[/tex] denotes initial population of bacteria.

Take [tex]P_0=2000[/tex], [tex]P(t)=50000[/tex] and [tex]k=0.657[/tex]

[tex]50000=2000e^{0.657t}\\\frac{50000}{2000}=e^{0.657t}\\25=e^{0.657t}\\0.657t=\ln 25\\t=\frac{\ln 25}{0.657}=4.9\approx 5\,\,days[/tex]

Answer:

y=x+1

Step-by-step explanation:

The slope intercept form of a line is y=mx+b, where m is the slope of the line and b is the y intercept. Since the line rises one unit for every one unit it moves to the right, it has a slope of 1. Since it intersects the y axis at the point (0,1), it has a y intercept of 1. Therefore, the equation is y=x+1. Hope this helps!

Answer:

B

Step-by-step explanation:

its B because the input for every pair has the same output, if the input had different outputs it would be considered not a function. Imagine it like a vending machine, if you were to press 3 on the vending machine you would get whatever 3 was, but if you pressed 3 and you get something else besides whatever 3 is it would be broken.

Answer:

He had 11 five dollar bills.

Step-by-step explanation:

Since Jonah realized that he had twice as many one dollar bills as he has five dollars bills, and 6 less ten dollar bills as he has one dollar bills, if we say that the number of one dollar bills he has is "x", then the number of five dollar bills and ten dollars bills will be:

five dollar bills = [tex]\frac{x}{2}[/tex]

ten dollar bills = [tex]x - 6[/tex]

Since the total money he had was [tex]237[/tex], then the sum of all the bills he had multiplied by it's respective values must be equal to that:

[tex]\text{(one dollar bills)} + 5*\text{(five dollar bills)} + 10*\text{(ten dollar bills)} = 237\\x + 5*\frac{x}{2} + 10*(x - 6) = 237\\x +\frac{5*x}{2} + 10*x - 60 = 237\\11*x + \frac{5*x}{2} = 237 + 60\\\frac{22*x + 5*x}{2} = 297\\27*x = 297*2\\x = \frac{594}{27} = 22[/tex]

Therefore he had 11 five dollar bills.

Answer:

D. y/-1 = f(x)
