8 0

Answer:

7 muffins

Step-by-step explanation:

First, you must figure out how many times 9 can go into 88. That gives you 9.8. This tells you that 9 boxes will be filled completely. You then multiply 9 by 9 to figure out how many muffins that will be (81). Lastly, you subtract those (81) from the total muffins to find out how many muffins are left that will be in the small box.

A quadratic function is a function of the form y=ax^2+bx+c where a, b, and c are constants. Given any 3 points in the plane, the

pochemuha

Answer:

The quadratic function whose graph contains these points is $y=-x^{2}-2x-2$

Step-by-step explanation:

We know that a quadratic function is a function of the form $y=ax^{2}+bx+c$ . The first step is use the 3 points given to write 3 equations to find the values of the constants <em>a</em>,<em>b</em>, and <em>c</em>.

Substitute the points (0,-2), (-5,-17), and (3,-17) into the general form of a quadratic function.

$-2=a*0^{2}+b*0+c\\c=-2$

$-17=a*-5^{2}+b*-5+c\\c=-25a+5b-17$

$-17=a*3^{2}+b*3+c\\ c=-9a-3b-17$

We can solve these system of equations by substitution

Substitute $c=-9a-3b-17$

$-9a-3b-17=25a+5b-17\\-9a-3b-17=-2$

Isolate a for the first equation

$-9a-3b-17=-25a+5b-17\\a=\frac{b}{2}$

Substitute $a=\frac{b}{2}$ into the second equation

$-9\left(-\frac{b}{2}\right)-3b-17=-2$

Find the value of b

$-9\left(-\frac{4b}{17}\right)-3b-17=-2\\ b=-2$

Find the value of a

$a=\frac{b}{2}\\ a=-1$

The solutions to the system of equations are:

b=-2,a=-1,c=-2

So the quadratic function whose graph contains these points is

$y=-x^{2}-2x-2$

As you can corroborate with the graph of this function.

Serena wants to solve the following system of equations in the most efficient way.

Marianna [84]

Answer:

Serina should have solved for x in the second equation because it has a coefficient of 1.

Step-by-step explanation:

we have

$2x+3y=18$ ----> equation A

$x+7y=31$ ---> equation B

we know that

To solve the system of equations in the most efficient way, solve for x equation B and then substitute the value of x in equation A

so

$x=31-7y$ ----> equation C

substitute equation C in equation A

$2(31-7y)+3y=18$

solve for y

$62-14y+3y=18\\11y=62-18\\11y=44\\y=4$

Find the value of x

substitute the value of y in the equation C

$x=31-7(4)=3$

The solution is (3,4)

therefore

Serina should have solved for x in the second equation because it has a coefficient of 1.
