Jackson estimated 637 ÷ 78 as 640 ÷ 80. He reasoned that 64 tens divided by 8 tens should be 8 tens. Is Jackson’s reasoning corr

Sholpan [36]

Answer:

the correct solution has been explained

Step-by-step explanation:

Jackson,s reasoning is incorrect because it should be 8 ones and not 8 tens that would give 64

$\frac{640}{80} = \frac{64}{8} = 8$

Moreover, $\frac{637}{78} is\ not\ equal\ to \frac{640}{8}$

as $\frac{637}{78}= 8.16$

whereas $\frac{640}{80}$ = 8

clearly, both quantities are different

Write a quadratic equation with integer coefficients and the given numbers as solutions.

adoni [48]

Answer:

1.) f(x) = x*x - 7x + 10

2.) f(x) = x*x - 5x

3.) f(x) = 4*x*x - 5x - 6

4.) f(x) = 6*x*x -5x + 1

Step-by-step explanation:

1.) 2 and 5 (x -2)(x - 5) = f(x) = x*x - 7x + 10

2.) 0 and 5 f(x) = x*(x -5) = x*x - 5x

3.) -3/4 and 2 (x + 3/4)(x -2) = x*x - (5/4) x - 3/2,

need integers f(x) = 4xx - 5x - 6

4.) 1/2 and 1/3 (x - 1/2)(x - 1/3) = f(x)

x*x - 1/3 x - 1/2 x + 1/6

xx - 5/6 x + 1/6

6 xx - 5x + 1

If a(x)=2x-4 and b(x) =x+2, which of the following expressions produces a quadratic function?

ZanzabumX [31]

Answer:

$(ab)(x)$

Step-by-step explanation:

The complete question in the attached figure

we have

$a(x)=2x-4\\b(x)=x+2$

we know that

(ab)(x) is equal to the product of a(x) and b(x)

$(ab)(x)=(2x-4)(x+2)$

Applying distributive property

$(ab)(x)=2x(x)+2x(2)-4(x)-4(2)$

$(ab)(x)=2x^2+4x-4x-8$

$(ab)(x)=2x^2-8$

This is a quadratic equation

The other expressions not produce a quadratic equation
