1+4 =5 2+5=12 3+6=21 8+11=

Answers

Answer 1
Answer: 1 + 4 = 5
2 + 5 + 5 = 12
3 + 6 + 12 = 21
8 + 11 + 21 = 40
So the missing number is 40 and that we can see from the above deduction. Actually the number that we get from the previous addition is added with the next addition to get the result. This is the link between the equations.
Answer 2
Answer: It would be 40 because it adds the sum of the equation before it

The diameter of a circle has endpoints whose coordinates are R(-2, 2) and S(4, 2). what is the length of the radius?

Answers

Answer: 3 units

Step-by-step explanation:

Using distance formula :

√((x_2-x_1)^2+(y_2-y_1)^2)

The diameter of the circle with endpoints  R(-2, 2) and S(4, 2) will be

d=√((4+2)^2+(2-2)^2)=√(36)=6\ units

Since, the radius of a circle is half of the diameter.

Then the radius of the circle will be

r=(d)/(2)=(6)/(2)=3\ units

Hence, the radius of the circle = 3 units.

Use substitution to solve the sytem: 5x-3y=-20 and x=3y-16

Answers

5x - 3y = -20
x = 3y - 16

Plug in 'x' into the first equation:

5 (3y - 16) - 3y = 20
15y - 80 - 3y = -20
12y = 60
y = 5 

Plug in 'y' into the second equation to get 'x':

x = 3y - 16
x = 3(5) - 16
To get x = -1

y = 5
x = -1
5(3y-16)-3y = -20
15y-80-3y = -20
12y = 60
y = 5

Which of the following functions is not written in explicit form? y=x
x^2-6xy-9y^2=0
y=0
y=-squrt (1-x2)

Answers

Answer:

Option 2 and 3 are not written in explicit form.

Step-by-step explanation:

We have four functions we have to find which one of them are not written in explicit form:

Explicit form is the form in which we can finc the value of n.

Option 1 is correct

y=x because

we can calculate y and x by substituting different values.

Option 2 is incorrect because we can not calculate y from the given equation

x^2-6xy-9y^2=0

Option 3 is incorrect because y=0 we can not find anything.

Option 4 is correct because we can find values of y   by substituting different values of x in the given equation that is y=-\sqrt{(1-x^2).

There are 130 red, blue and green marbles in a bag. The ratio of red to blue to green is 5:3:2 respectively. How much marbles in the bag are blue?

Answers

5 parts are red
3 parts are blue
2 parts are green

There are 10 parts in the bag altogether, and they add up to 130 marbles.
So each 'part' is 13 marbles.

Red = 5 parts = 65 marbles
Blue = 3 parts = 39 marbles
Green = 2 parts = 26 marbles

65 + 39 + 26 = 130 so we ended up on the track.
One would take the ratios, and add them. 
5+3+2 = 10
The divide the total number of marbles by the sum of the ratios.
130/10 = 13
And finally multiply the quotient by each of the three numbers in the ratio (5:4:3) to get the number of marbles that are each colour. 
Red: 13 * 5 = 65
Blue: 13 * 4 = 52
Green:  13 * 3 = 39 
Therefore, there are 52 blue marbles in the bag. 

Give the degree and classify the polynomial by the number of terms. 2x + 1 A. degree: 0; monomial B. degree: 1; binomial C. degree: 0; binomial D. degree: 1; monomial

Answers

If there are no exponents within then the highest power is one. Since there are two terms within (2x and 1) then it is a binomial. 
The Correct answer is B. Degree: 1;Binomial Hoep you get it correct
