What is the equation of the line perpendicular to y=2x+3.14 going through the points (2,4)?

inessss [21]

Answer:

$x+2y-10=0$

Step-by-step explanation:

Consider an equation: $y=mx+c$

Here, m is the slope of the line and c is the y-intercept.

Given equation is $y=2x+3.14$

Here, slope is $m=2$

As product of slopes of two perpendicular lines is equal to $-1$ , slope of the required line is $m_1=\frac{-1}{m}=\frac{-1}{2}$ .

Let $(x_1,y_1)=(2,4)$

Equation of the required line is $y-y_1=m_1(x-x_1)$

$y-4=\frac{-1}{2}(x-2)\\2(y-4)=-1(x-2)\\2y-8=-x+2\\x+2y-8-2=0\\x+2y-10=0$

The sum of two items will be the two items added, and in this case, it is 5 and y, or

5 + y.

"Greater than or equal to 7"

Here, use the symbol, ≥, and 7.

≥ 7

Combine those to get the final equation:

Deffense [45]

Your question does not make sense unless you can estimate but the answer would be 20.625

Work:
You have to multiply 5.50 to 3.75 because 45 is 75 percent of 60
