Answer:

Sue has 8 marbles

Molly has 8 marbles

Step-by-step explanation:

m = number of marbles Molly has

s = number of marbles that sue has

m+s =32

m = 3s

Substitute the second equation into the first equation

3s+s =32

4s = 32

Divide by 4

4s/4 =32/4

s = 8

Sue has 8 marbles

m = 32 = 3*8 = 24

Molly has 8 marbles

-x^2+4x-8 <br>axis of symmerty

V125BC [204]

Answer:

$\boxed {\boxed {\sf x=2}}$

Step-by-step explanation:

The axis of symmetry can be calculated using the formula:

$x=\frac{-b}{2a}$

First we must determine a and b from the quadratic: $-x^2+4x-8$ . This is in standard form, with the highest power first in descending order.

Standard form is also: $ax^2+bx+c$

If we compare this to the quadratic given, we can conclude that:

$a= -1 \\b= 4 \\c= -8$

Substitute the values for a and b into the formula.

$x= \frac{-(4)}{2(-1)}$

Multiply in the denominator.

$x=\frac {-4}{-2}$

Divide.

$x=2$

This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.

frutty [35]

Answer:

B. 6 1/4

Step-by-step explanation:

The computation of the more flour Nicholas needed for making the cake and cookies is shown below:

$11 \frac{3}{4} - 5\frac{1}{2}$

= 11.75 - 5.50

= 6.25 more cups of flour

Therefore to make the cookies and cakes, 6.25 more cups of flour is required or needed and the same is to be considered

hence, the correct option is B. 6 1/4
