help plz. I have no idea what i'm doing!

Answer:

y = 2/5x + 7

Step-by-step explanation:

substitute 2/5 in for m and (-5,5) in for (x,y) respectively to find the y intercept

y=mx+b

5 = 2/5(-5) + b

5 = -2 + b

add 2 to both sides to solve for b (y intercept)

b = 7

therefore the equation for the line will be...

y = 2/5x + 7

5+5

Step-by-step explanation:

Answer:

Step-by-step explanation:

They all end in 0 or 5 except 627, so all but 627 are divisible by 5.

The following are divisible by 3

285

627 is divisible by 3 (but not 5)

5490 is divisible by 3

7290 is divisible by 3

15780

43695

===============

So your answer is

7295

I think that's the only one divisible by 5 but not 3.

===============

There's a quick way to divide by 3. Just add the digits. If the sum is divisible by 3 then the whole number is divisible by 3

For example 285

2 + 8 + 5 = 15.

15 is divisible by 3 so 285 is divisible by 3.

==================

7295 = 7 + 2 + 9 +5.  Anything adding up to 9 you can cast out.

7 + 2 = 9 Cast it out

9 = 9       Cast it out

5  is not divisible by 3, so 7295 is not divisible by 3

Answer:

They have the same amount of tokens after t = 7.6 hours

Step-by-step explanation:

Since Gavin initially has 50 token and rides the roller coaster three times per hour, he uses 3 token per hour. So, the number of token he losses after t hours is 3 token per hour × t hours = 3t. Thus, the number of tokens left after t hours is T = 50 - 3t

Since Gibson initially has 12 tokens and finds two tokens on the ground per hour, he gains 2 tokens per hour. So, the number of token he gains after t hours is 2 token per hour × t hours = 2t. Thus, the number of tokens he has after t hours is T' = 12 + 2t

To calculate the time t when they will have the same tokens, T must be equal to T', that is T = T'.

So, 50 - 3t = 12 + 2t

collecting like terms, we have

50 - 12 = 3t + 2t

38 = 5t

dividing both sides by 5, we have

t = 38/5

t = 7.6 hours

So, they have the same amount of tokens after t = 7.6 hours

Exponent Rules

We need to recall this fundamental rule for exponents:

[tex]\displaystyle \sqrt[n]{a^m}=a^{m/n}[/tex]

We are given the expression:

[tex]f(n)=\left ({\sqrt[{12}]{2}}\,\right)^{n-49}\times 440\,{\text{Hz}}[/tex]

We'll use algebra and the above rule to manipulate the expression.

First, get rid of the unit Hz and move the coefficient 440 to the left:

[tex]f(n)=440\left ({\sqrt[{12}]{2}}\,\right)^{n-49}[/tex]

Now we convert the radical into an exponent form:

[tex]\displaystyle \left ({\sqrt[{12}]{2}}\,\right)^{n-49}=(2)^{\frac{n-49}{12}}[/tex]

Substitute:

[tex]f(n)=440\left ({\sqrt[{12}]{2}}\,\right)^{n-49}=440~(2)^{\frac{n-49}{12}}[/tex]

This is the very same expression in formula 2, as required.

Answer:

x<120

Step-by-step explanation:

-30<x/-4

In order to simplify this, we must isolate the x value by multiplying both sides by -4

Since we are dealing with inequalities and we are multiplying by a negative number, we have to switch the sign (<,>)

-30(-4)>x

x<120

Answer:

this copy and paste is to hard to read making it impossible to solve sorry.

Step-by-step explanation:

The value of the expression is 256.

Simplification of an expression is the process of writing an expression in the most efficient and compact form without affecting the value of the original expression. It involves, multiply out the brackets and then simplify the resulting expression by collecting the like terms.

For the given situation,

The expression is  $x^{6} + (y^{2} \div z^3)\cdot w^3$

⇒ [tex]x^{6}(\frac{y^{2} }{z^{3} } )(w^{3} )[/tex]

Substitute $x=2$, $y=3^2$ = 9$, $z=3$, and $w=4$,

⇒ [tex]2^{6}(\frac{9^{2} }{3^{3} } )(4^{3} )[/tex]

⇒ [tex]64+(\frac{81}{27} )(64)[/tex]

⇒ [tex]64+(3)(64)[/tex]

⇒ [tex]64+192[/tex]

⇒ [tex]256[/tex]

Hence we can conclude that the value of the expression is 256.

Answer: 17.4 cm

Step-by-step explanation: All you have to do is add all of the sides together.

So 8.5+8.5+0.2+0.2

=17+0.4

=17.4 cm

Answer:

17.4 cm

Step-by-step explanation:

A rectangle has two sets of parallel, equal sides. So that means two of the sides are equal to 8.5cm and the other two sides are equal to 0.2cm. When you put that in an equation:

8.5 + 8.5 + 0.2 + 0.2 = 17.4

Answer:

y = 1/2x + 3.

Step-by-step explanation:

y = -2x + 8

Gradient = -2

Gradient of the line passing through point (-4,1)

is given as 1/2. i.e it is perpendicular to y = -2x + 8

Its equation is given as:

y - y1 = m(x - x1)

y - 1 = 1/2(x -(-4))

y - 1 = 1/2(x + 4)

y - 1 = 1/2x + 2

y = 1/2x + 3.

When finding the Y-Intercept from a Graph, you should find where the line from the equation crosses the y-axis. The point where the equation crosses the y-axis is the Y-Intercept.

Step-by-step explanation:

Answer: C

Step-by-step explanation:

The function is always increasing

The function is increasing when x>0 for the graph of [tex]y= \sqrt[3]{x}[/tex] as parent function.

" The graph is defined as the representation of relation between two variables on the coordinate plane."

According to the question,

Given graph of the  cube root parent function

For function [tex]y= \sqrt[3]{x}[/tex]

x = 0 ⇒ y = 0

x = 1 ⇒ y = 1

x = 8  ⇒ y = 2

x = 27 ⇒ y = 3

Therefore, for x>0, function [tex]y= \sqrt[3]{x}[/tex] is increasing.

Hence, Option(D) is the correct answer.
