8.4 divide by 4 and you get 2.1.

Answer 2

Answer: a) Scale factor is = Second Value / First Value
= 8.4 / 4 = 2.1

b) 0.25 = Second Value / First value

0.25 = Second Value / 9

Second value = 0.25 * 9 = 2.25.

What is the domain for the piece of the function represented by f(x)=x+1

Answers

Answer:

(-∞, ∞)

Step-by-step explanation:

As you can see for each value of x , f(x) is defined

example , for x = -8000 , f(x) is defined to be -7999.

for x = 0 , f(x) is defined to be 1.

for x = 8000 , f(x) is defined to be 8001.

Also,

By its graph , Which is a straight line , So, it is defined everywhere

Thus,

its domain is(-∞, ∞)

Which is greater 1/2 or 1/6

Answers

1/2 since it is closer to 1 whole

1/2 cuz 1/6 has shorter pieces u would want 1/2 big pieces then little pieces

615.44 to the nearest hundredth

Answers

When rounding, look to the next place to the right of what you are rounding to... for example if you are rounding to the nearest hundredth, look to the thousandths place to see if the hundredths place rounds up or down. Since your number, 615.44 stops on the hundredths place, the thousandths place is automatically zero, so your number stays the same.

615.44

PLEASE HELP!!!!!!!!!Let x^2+bx+c = 0 be a quadratic whose roots are each two more than the roots of 3x^2-5x-7. What is c?

Answers

Let $x_1 , x_2$ be the roots of the equation $3x^2-5x-7$ . By the Viet theorem you have that $\left \{ {{x_1+x_2=- (5)/(3) } \atop {x_1x_2= (-7)/(3) }} \right.$ .

For the equation $x^2+bx+c = 0$ you'll have that $c=(x_1+2)(x_2+2)=x_1x_2+2(x_1+x_2)+4=(-7)/(3)+2\cdot(- (5)/(3) )+4$
That is $(-7)/(3)- (10)/(3) +4=- (5)/(3)$ .

Answer: $- (5)/(3)$
