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 $y-y_1=m_1(x-x_1)$

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

A large serving of soup from a take-out restaurant is 4/5 liter. The restaurant has 3 liters of soup. The diagram below models t

Airida [17]

Answer:

The quantity of total serving soup does restaurant has = T = 2 $\dfrac{2}{5}$ liters .

Step-by-step explanation:

Given as :

The quantity of large serving soup = $\dfrac{4}{5}$ liters

The total quantity of soup does restaurant has = 3 liters

Let the quantity of total serving soup does restaurant has = T liters

So, According to question

The quantity of total serving soup does restaurant has = The quantity of large serving soup × total quantity of soup does restaurant has

Or, T = $\dfrac{4}{5}$ × 3

Or, T = $\frac{4\times 3}{5}$

Or, T = $\dfrac{12}{5}$

∴ T = 2 $\dfrac{2}{5}$ liters

So, quantity of total serving soup does restaurant has = T = 2 $\dfrac{2}{5}$ liters

Hence,The quantity of total serving soup does restaurant has = T = 2 $\dfrac{2}{5}$ liters . Answer

Solve each system of eaquasions x+4y=4 -x+2y=8

bazaltina [42]

X + 4y = 4
-x + 2y = 8

x + 4y - x + 2y = 4 + 8

6y = 12

y = 2

x + 4(2) = 4
x + 8 = 4
x = -4

(x,y)
(-4,2)

Sergeu [11.5K]

Answer:

$13087.92

Step-by-step explanation:

formula: ab^x

a= starting amount

a= 5072

b= 1+r

r=rate

r=9%=0.09

b=1+0.09 =1.09

x= 11 (years)

account after 11 years:

= 5072(1.09)^11

=13087.9227277

= 13087.92
