0.4, 0.9, 1.4, 1.9

How much do you add to get from 0.4 to 0.9? 0.5. How about from 0.9 to 1.4? 1.4 to 1.9? All 0.5.

This is a pattern, meaning we can use it to find the next terms.

What is 1.9 plus 0.5? 2.4.

Now, 2.4 plus 0.5? 2.9.

How about 2.9 plus 0.5? 3.4.

So, your next three terms are 2.4, 2.9, and 3.4.

Solve this system of equations using elimination with multiplication
romanna [79]

Answer:

Step-by-step explanation:

3x - 4y = -11

x - 2y = -5

Compare the coefficients of the variables.

The coefficients of the x terms, 3 and 1, are multiples of each other.

The coefficients of the y terms, -4 and -2, are also multiples of each other.

That makes it easy to eliminate either variable.

I'll eliminate the y variables. Multiply the second equation by -2, then add it to the first equation:

₋-2x + 4y = 10

 3x - 4y = -11

--------------------

 x + 0y = -1 ,  so x = -1.

Substitute -1 for x in either equation and solve for y:

3(-1) - 4y = -11

y = 2

(x,y) = (-1, 2)

Replace the # symbols in the row 1 function to match the graph below f(x)=(x+5)(x+#)(x-1)(x-#)​
matrenka [14]

Answer:

3, 5

Step-by-step explanation:

Looking at the graph, the x-intercepts are -5, -3, 1 and 5.

Hence the graph equation is (x+5)(x+3)(x-1)(x-5)

1 point) According to one mathematical model, the average life expenctancy for American men born in 1900 was 55 years. Life expe
xxMikexx [17]

  a)

Let t represents number of years after 1900

so that means for 1900, value of t is 0

We are given point as (0,55)

and it says that life expectancy increases by 0.2

so that means slope,m=0.2

equation of line is y=mt +b

or y=0.2t +b

now we use point (0,55)

55 =0.2(0) +b

55 =0+b

55= b

so b=55

plug it back into the equation,we get

y=0.2t +55

b)

We are given y=73

so we plug it into the equation we got in part a and solve for t

y=0.2t +55

73 =0.2t +55

73-55 =0.2t

18 =0.2t

18/0.2 =t

90 =t

so t=90

This means the birth year =1900+t =1900+90 =1990
