Answer:

X=-7

Step-by-step explanation:

When "subtracting" negatives it's basically like adding them together, but the numbers get farther away from 0 going left... The equation could look like

-7 - 2 = -9 <em>or </em>-7 + (-2) = -9 :)

Which quadratic function has a vertex point of (3,5) and passes through the<br> point (-2,55)?
Alex17521 [72]

9514 1404 393

Answer:

  f(x) = 2(x -3)² +5

Step-by-step explanation:

For vertex (h, k) and scale factor 'a', the vertex form is ...

  f(x) = a(x -h)² +k

We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.

  55 = a(-2 -3)² +5

  50 = 25a . . . . . . . . subtract 5

  a = 2 . . . . . . . . . . . divide by 25

So, the function is ...

  f(x) = 2(x -3)² +5

__

In standard form, that will be ...

  f(x) = 2x² -12x +23

19. When the members of a high school club are
Korvikt [17]

9514 1404 393

Answer:

 B.  25 people

Step-by-step explanation:

The remainders tell you the number will be 1 more than some multiple of the least common multiple (LCM) of 2, 3, and 4. The LCM is 3·4 = 12, so we want some multiple (n) of that such that 12n+1 is a multiple of 5. We know this is the case for n=2.

The least number of people who could be in the club is 2·12+1 = 25.

2x - 5y = 4<br> 3x - 7y = 5
VMariaS [17]

Answer:

(-3,-2)

Step-by-step explanation:

2x-5y=4

3x-7y=5

solve the equation

x=2+5/2y

3x-7y=5

substitute the value of x into an equation

3(2+5/2y)-7y=5

multiply 3 to 2. and. 3 to 5/2y

6+15/2y-7y=5

minus 6 to 5 and. add 15/2y to -7y

-1/2y=1

divide both sides by -1/2

y= -2

substitute the value of -2 into an equation

x=2+5/2•(-2)

multiply 5/2 to -2

x=2+-5

add but since 5 is negative then subtract the numbers

x= -3

combine y= -2 and x= -3 as a point

So the answer is (-3,-2)
