6x+6y=30 and 4x+8y=30.60

1 answer:

6 0

<span>Simplifying 4x + 8y = 30.60 Solving 4x + 8y = 30.60 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8y' to each side of the equation. 4x + 8y + -8y = 30.60 + -8y Combine like terms: 8y + -8y = 0 4x + 0 = 30.60 + -8y 4x = 30.60 + -8y Divide each side by '4'. x = 7.65 + -2y Simplifying x = 7.65 + -2y</span>

1. Which of the following coordinates for p will make line mn perpendicular to line op in the diagram below?

TiliK225 [7]

1. (3,2)....because when finding the slope, we find the the slope of mn and the slope of op are negative reciprocals.

2. y = 5x - 7.....slope here is 5....perpendicular line has a negative reciprocal slope...so the slope has to be -1/5

y= mx + b
slope(m) = -1/5
(-10,3)...x = -10 and y = 3
now we sub and find b, the y int
3 = -1/5(-10) + b
3 = 2 + b
3 - 2= b
1 = b
so ur perpendicular equation is : y = -1/5x + 1

Determine whether the given differential equation is separable. StartFraction dy Over dx EndFraction plus 2 sine (x minus y )equ

Natalka [10]

Answer:

$dy/dx+2sin(x-y)=0$

so whether the given equation is separable or not

$dy/dx= -2sin(x-y)$

the given equation is not separable because the argument inside the function is dependent on both x and y

even though we use the formula to open the sin(A-B) we would still get the function dependent on both x and y and the equation would get complicated so instead use any other method.

Travis is cutting strips of paper for a project. He needs strips that are 114 inches wide. He cut his first strip too wide. His

Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches

<h3>What is the percentage?</h3>

It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.

We have:

The length Travis needs to cut = 114 inches

Percent of error = 10%

Let's assume he cuts x inches wide strip

So from the percent of error formula:

$\rm \dfrac{x-114}{114} = \dfrac{10}{100}$

$\rm x = \dfrac{114}{10}+114$

$\rm x = \dfrac{1254}{10}\Rightarrow \dfrac {627}{5}$ or

$\rm x = 125\dfrac{2}{5} \ inches$

Thus, Travis cuts 125 whole 2/5 inches wide strip if the percent of error was 10% the actual length of the strips he needs to cut was 114 inches
