Answer:

Down below

Step-by-step explanation:

1. 3/4x-7-16, combine -7 and -16, 3/4x-23

2. -8+2y+4, combine -8 and 4, 2y+4

3. -4x+11x+3y, combine -4x and 11x, 7x+3y

4. 41+b-25b, combine b and -25b, 41-24b

5. -1/2(8x-2), distribute: -1/2*8x and -1/2*-2, -4x+1

6. $40, 15% off: 40(1.00-0.15)= $34

So simplifying expressions means to just combine like terms (e.g. 2 and 4, 5x and -18x, 7y and y, etc.)

Distribution means to apply the multiplication to the terms inside the parentheses (e.g. a(x+y) -> ax+ay)

Sales is just: original price * (1 - percent off by)

I hope this helps!

jonny [76]

Answer: 512 times

Step-by-step explanation:

$$$Volume of Solid $A=5632 \mathrm{~cm}^{3}$ \\Volume of Solid $B=11 \mathrm{~cm}^{3}$.\\Divide volume of Solid $A$ by volume of Solid $B$.\\Volume of Solid A\\Volume of Solid $B$\\$

$\frac{5632 \mathrm{~cm}^{3}}{11 \mathrm{~cm}^{3}}=512\\\\$$\text{Therefore, Solid $A$ is 512 times larger thm Solid B}$

Please help me please will give brainliest to anyone only do number 11

AnnZ [28]

9514 1404 393

Answer:

9. ±1, ±2, ±3, ±6

11. ±1, ±2, ±3, ±4, ±6, ±12

Step-by-step explanation:

The possible rational roots are (plus or minus) the divisors of the constant term, divided by the divisors of the leading coefficient.

Here, the leading coefficient is 1 in each case, so the possible rational roots are plus or minus a divisor of the constant term.

9. The constant is -6. Divisors of 6 are 1, 2, 3, 6. The possible rational roots are ...

±{1, 2, 3, 6}

11. The constant is 12. Divisors of 12 are 1, 2, 3, 4, 6, 12. The possible rational roots are ...

±{1, 2, 3, 4, 6, 12}

Which function has the greatest rate of exponential growth?

Veronika [31]

Answer:

Step-by-step explanation:

Here, we want to find which of the expressions have the greatest rate of exponential growth.

The easiest way to go about this is have a substitution for the term t;

Let’s say t = 6

Thus;

h(t) = 1.18^1 = 1.18

K(t) = 0.375^6 = 0.002780914307

f(t) = 1.36^6 = 6.327518887936

g(t) = 0.86^6 = 0.404567235136

Another way to find this is to express each as a sum of 1

f(t) = (1+ 0.36)^t

g(t) = (1-0.14)^t

k(t) = (1-0.625)^t

We can see clearly that out of all the terms in the brackets asides 1, 0.36 is the biggest in value

The population of Portland Oregon has recently grown to more than 500,000. What is the order of magnitude for the number of peop

miss Akunina [59]

Answer:

Order is 6

Step-by-step explanation:

The population of Portland Oregon has recently grown to more than 500,000.

The order of magnitude for the number of people in Portland means the power of 10. It means that we need to write 500,000 in form of 10 to the power. So,

$P=500,000$

It contains 6 zeroes. It means,

$P=5\times 10^6$

So, the order of magnitude for the number of people in Portland is 6.
