How do I simplify 3(x-4)-5(z+2x) ?
I have it down to 3x-(-12)-5z+2x because I multiplied the first set of parenthesis by 3 and the second set by -5. The answer is -7x-5z-12 but how do I get there?

Answers

Answer 1
You first step was wrong. This is the correct procedure…

3(x - 4) - 5(z + 2x)

3x - 12 - 5z - 10x

From here, combine like terms.

-7x - 5z -12

A newborn baby has about 26,000,000,000 cells. An adult has about 4.94 x 10^*13 cells. How many times as
many cells does an adult have than a newborn? Enter your answer in scientific notation.
An adult has about =
times more cells than a newbom baby.

Answers

Answer:  1.9 × 10³

Step-by-step explanation:

New born = 2.6 × 10¹⁰ cells.

Adult         = 4.94 × 10¹³ cells.

How many times more = adult cells ÷ newborn cells

                                      = 4.94 × 10¹³ cells ÷ 2.6 × 10¹⁰ cells

                                      =  1.9 × 10³ cells

∴ adults have about 1.9 × 10³ more cells than newborn babies.

Function 2
y = 4x + 1

How much more is the rate of change of function 2 than the rate of change of function 1?

A)1
B)2
C)3
D)4

Answers

Answer:

The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

Step-by-step explanation:

The rate of change is also known as slope. The slope of a linear function or a line is

It is given that the function 1 is passing through the points (0,3) and (4,3). Slope of function 1 is

Therefore the slope of first function is 0.

The slope intercept form of a line is

Where, m is the slope and b is y-intercept.

The second function is

Therefore the slope of second function is 2 and the y-intercept is 1.

The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

please help me, i don’t get this

Answers

Step-by-step explanation:

you do know that f(x) is the same as y ?

because the y value is the result of a function (in 2-dimensional space).

for such questions we only need to look at the term with the highest exponent of x.

with large values of x this term then "drowns" out all other terms regarding the dimension of the "limit" the range (= functional results) of the function can reach.

so, the term with the highest exponent of x is here

-4x⁶

all the other terms with x⁵, x⁴, x³, ... are much, much smaller in absolute value than |-4x⁶| for really large values of x (x going to infinity, but also to -infinity).

as explained, the term -4x⁶ is therefore driving the limit or end behavior of the function.

so, what happens here, when x goes to +infinity ?

then x⁶ goes to +infinity.

and that means 4x⁶ goes to +infinity.

but that means -4x⁶ goes to -infinity !

and when x goes to -infinity ?

then x⁶ still goes to +infinity (remember, multiplying 2 negative values gives a positive result, so any form of squaring incl. any even exponents will already have positive results).

and that means 4x⁶ goes to +infinity.

but again, -4x⁶ goes then to -infinity.

so the right answer choice is the second one, where y goes to -infinity in both cases.

Given the function g ( x ) = x 2 + 10 x + 20 g(x)=x 2 +10x+20, determine the average rate of change of the function over the interval − 9 ≤ x ≤ − 3 −9≤x≤−3.

Answers

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(g(-3) - g(-9)) / (-3 - -9)

g(-3) = (-3)² + 10×-3 + 20 = 9 - 30 + 20 = -1

g(-9) = (-9)² + 10×-9 + 20 = 81 - 90 + 20 = 11

-3 - -9 = -3 + 9 = 6

(-1 - 11) / 6

-12/6 = -2

the average change rate in this interval is -2 (or fully -2/1).

A college student has $240 to use for laundry money. Each time he does laundry, he spends $7.50. Which equation represents the amount of money, M, he has after he has done laundry “x” times?
A) M= 7.50x - 240
B) M= 240 - 7.50x
C) M= 7.50 - 240x
D) M= 240x - 7.50

Answers

Answer:

B

Step-by-step explanation:

x = the number of times he does laundry.

Let's say he does the laundry 5 times then x = 5.

Each time costs $7,50.

If you want to know how much money he has spent after 5 times, you have to calculate 5 times $7,50. 7,5 times 5 = 37.5.

M stands for how much money he still has left from the 240 dollars.

If you apply the formula it would be 'M = 240 - 7.50x (7.50 times 5) = 240 - 37.5 = 202.5'

Therefore, the correct answer is B (M = 240 - 7.50x).
