I need a equation written for this pleeeeeaaaassse! The constant of proportionality is 2.
but I need an equation for this, I have an attachment for you to help. g= c is not correct sorry.

Answers

It sounds like your teacher wants g = 2c as the answer. The constant of proportionality simply tells us what to multiply the input variable by, to get the output variable.

It's similar to saying y = 2x, but we use c in place of x and use g in place of y.

The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour. If
the depth after 6 hours of draining is 8 feet then write an equation for the water depth, d, as a function of the
amount of time it's been draining, t, in hours.

Answers

The linear function for the depth of water after t hours is given by:

[tex]d(t) = 17 - 1.5t[/tex]

The format of a linear function is given as follows:

[tex]d(t) = d(0) - at[/tex]

In which:

d(0) is the y-intercept, which is the initial value.a is the slope, which is the rate of change.

The depth of water in a water tower that is draining is decreasing at a constant rate of 1.75 feet per hour, which means that [tex]a = -1.75[/tex], thus:

[tex]d(t) = d(0) - 1.5t[/tex]

The depth after 6 hours of draining is 8 feet, which means that when [tex]t = 6, d(t) = 8[/tex]. This is used to find d(0).

[tex]d(t) = d(0) - 1.5t[/tex]

[tex]8 = d(0) - 1.5(6)[/tex]

[tex]d(0) = 17[/tex]

Then

[tex]d(t) = 17 - 1.5t[/tex]

Apply PEMDAS order of operations:

→ Parentheses

→ Exponents

→ Multiplication

→ Division

→ Addition

→ Subtraction

________________

[tex]\frac{3}{5}+2^2-\frac{2}{5}\left(8-6\right)\div \:3=4\frac{1}{3}[/tex]

1) Parentheses:

[tex]\left(8-6\right)[/tex]

[tex]8-6[/tex]

[tex]=2[/tex]

[tex]\frac{3}{5}+2^2-\frac{2}{5}\times \:2\div \:3[/tex]

2) Exponents:

[tex]2^2[/tex]

[tex]=4[/tex]

[tex]\frac{3}{5}+4-\frac{2}{5}\cdot \:2\div \:3[/tex]

3) Multiplication/Division:

[tex]\frac{2}{5}\times \:2\div \:3[/tex]

[tex]\frac{2}{5}\times \:2[/tex]

Convert to fraction:

[tex]2=\frac{2}{1}[/tex]

[tex]\frac{2}{5}\times \frac{2}{1}[/tex]

Multiply 2 × 2, and 5 × 1:

[tex]=\frac{4}{5}[/tex]

[tex]\frac{4}{5}\div \:3[/tex]

Convert to fraction:

[tex]3=\frac{3}{1}[/tex]

[tex]\frac{4}{5}\div \frac{3}{1}[/tex]

Apply fraction rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]

[tex]\frac{4}{5}\times \frac{1}{3}[/tex]

Multiply 4 × 1 and 5 × 3:

[tex]\frac{3}{5}+4-\frac{4}{15}[/tex]

4) Addition/ Subtraction:

[tex]\frac{3}{5}+4[/tex]

[tex]=\frac{23}{5}[/tex]

[tex]\frac{23}{5}-\frac{4}{15}[/tex]

[tex]=\frac{13}{3}[/tex]

find the sum of all possible four digit numbers that can be formed using the digits 2,4,5,6,7 and 8 with no repeated digits

Answers

1+1
2+2
5+0
3+3
6+2-1
4+4

Answer:

2133120

Step-by-step explanation:

using 6 given digits, lets create a 4 digit number:

to choose the first number, you have 6 options. to choose the second number we have 5 options left. for the third number we have 4 options left. and for the fourth number, we have 3 options left.

6*5*4*3 = 360

with no repeats, 360 numbers can be formed.

this means that each number will occur 60 times each (360/6 digits)

so to find the sum:

60*(2+4+5+6+7+8) = 1920

but, we have one more thing:

In the thousands place, our sum of digits is multiplied by 1000; in the 100’s place, by 100; in the ten’s place, by 10; and in the one’s place, by 1. so:

1920(1000+100+10+1) = 1920*1111 = 2133120

F(x) =2x-1 what is the value of f(x) when x = -1

Answers

Answer:

f(x) = -3 when x = -1

Step-by-step explanation:

Let's go through this!

So our equation is f(x) = 2x - 1

we are asked for the value of f(x) when x = -1

Let's consider this, the f(x) value is the y value

and the x value in f(x) is the x value

So when x = -1

what is the y value?

we can use the equation to subsitute -1 into x and solve for f(x)

f(x) = 2(-1)-1

f(x) = -3

Our answer is -3
