one number is 7 more than twice the other number. if the sum of the two numbers is 19, find the two numbers
topjm [15]

Answer:

4 and 15

Step-by-step explanation:

Let the two numbers be a and b.

The sum of the two is 19. Therefore:

a+b=19

One number (let's use a) is 7 <em>more</em> than twice the other. Thus:

a=7+2b

Solve for the system of equations. Substitute the second equation into the first:

a+b=19\\(7+2b)+b=19

Subtract 7 from both sides:

2b+b=12

Combine like terms:

3b=12

Divide by 3:

b=4

So, b is 4.

And since they add up to 19, this means that a is:

a+b=19\\a+4=19\\a=15

So our numbers are 4 and 15

And we are done :)

use the coordinates of the vertex and the point to write the quadratic equation in standard form (-2, -2) point (-1, 1)
kogti [31]

Answer:

Step-by-step explanation:

vertex form of quadratic: y = a ( x − h ) ^ 2 + k

h= -2 , k = -2

y=a(x+2)^2-2

Substitute (-1,1)

1=a(-1+2)^2-2

a=3

y=3(x+2)^2-2

Expanding and give

y=3x^2+12x+10
