For v = -3(r - 3) when r= -1, what does v equal

Answer:

3(x+15) is the answer

Step-by-step explanation:

The equation x+15 repeats 3 times so you would have to create an equation to multiply x+15 3 times.

3x+15 is wrong because its only multiplying x by 3 and ignoring 15

x+45 is wrong because it is only multiplying 15 by 3 and ignoring x

x+15 is wrong because it is not multiplied by 3

3(x+15) is correct because it is the only answer that multiples 3 with both terms

Hope this helps

Answer:

Lets say that x is the number 5,

Step-by-step explanation:

5 divided by 15 = 0.33333333333

5 divided by 0.33333333333 = 15

5 + 15 + 5 + 15 + 5 + 15=60

(I know im all over the place with this, but this is just what i do)

60 - 15 = 45

15 + 45 = 60  

I know this is random but maybe you may figure it out or get a random hint??, 3(x+15) is 3x + 45

PRETTY SURE ITS 3(x+15) Please give me brainliest i sat here for like 24 mins trying to figure this out :(

Answer:

6

Step-by-step explanation:

32 = 12 + 4 ( z - 1 )

32 - 12 = 4 ( z - 1 )

20 = 4 ( z - 1 )

20 / 4 = z - 1

5 = z - 1

z - 1 = 5

z = 5 + 1

z = 6

Explanation:

Anything is categorized by how it matches with the definition of the category.

A composite number is a product of primes. A prime number is divisible only by itself and 1.

If a number has more than one prime factor (even if that is just multiple instances of the same prime factor), it goes into the composite number category. If its only prime factor is itself, it goes into the prime number category.

"keep-change-flip" is a strategy used to dividing fractions.

always change the mix fraction to a improper fraction and you slove.

I'll do the first one and the rest is basically done the same way.

for the last fraction equation I cross multiply the 4 divided into 4 gives you 1 and the 3 divided into 21 gives you 7.

Answer:

solve each proportion

how do you do this?

Step-by-step explanation:

The equation of the tangent line to the curve is:

[tex]y - 4 = 0.0024(x - 2)[/tex]

Which has a slope of 0.0024.

The tangent line of a curve [tex]f(x)[/tex] at a point [tex](x_0,y_0)[/tex] is given by:

[tex]y - y_0 = f^{\prime}(x_0)(x - x_0)[/tex]

In this problem, the curve is:

[tex]f(x) = e^{-4x}\sin{6x}[/tex]

The derivative is:

[tex]f^{\prime}(x) = -4e^{-4x}\sin{6x} + 6e^{-4x}\cos{6x}[/tex]

Point P(2,4), thus [tex]x_0 = 2, y_0 = 4[/tex].

The slope is:

[tex]f^{\prime}(2) = -4e^{-4(2)}\sin{6(2)} + 6e^{-4(2)}\cos{6(2)} = 0.0024[/tex]

Then, the equation of the line is:

[tex]y - y_0 = f^{\prime}(x_0)(x - x_0)[/tex]

[tex]y - 4 = 0.0024(x - 2)[/tex]

Answer:

[tex]46[/tex]

Step-by-step explanation:

Hey there,

Before solving the sum you have to know about the BODMAS theorem.

That means you have to solve this sum according to the BODMAS theory.

BODMAS theory is,

B - Brackets

O - Of

D - Division

M - Multiplication

A - Addition

S - Subtraction

Let us solve the sum now.

[tex]3 \times {2}^{3} + {5}^{2} - 18 \div 6 \\ 3 \times 8 + 25 - 18 \div 6 \\ 24 + 25 - 3 \\ 49 - 3 \\ = 46[/tex]

Answer:

No,the price is not within their budget.

Step-by-step explanation:

Because if you take 144 times 76 you get 10,944 which goes past their budget of 10,000

Answer:

They are over budget by $1,232.

Step-by-step explanation:

They want to replace 144 computer monitors each for $76.

$76 * 144 = $11,232

Their budget is $10,000 so they would be over budget by:

$11,232 - $10,000 = $1,232

Marta has a better estimate

Step-by-step explanation:

cause let's round both one to the nearest ten. 260*30

then let's cancel both zeros to make it easier

26*3=78 and just add on two zeros at the end

clearly Marta estimate is better as it is closer to 7800
