Answer:

4x + y = 43

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Given

y = 43 - 4x ( add 4x to both sides )

4x + y = 43 ← in standard form

Answer:

60.4 degrees

Step-by-step explanation:

Complementary angles are 2 angles that add up to the sum of 90 degrees.

90-29.6=60.4 degrees

The perimeter of a triangular sail is 44 feet. One side of the sail measures 18 feet and the second side measures 11 feet. What

Fantom [35]

Answer: The length of third side is 15.

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The perimeter of given triangle is 44.

One side, suppose a is 18.

Second side, suppose b is 11.

Suppose, third side is c.

So the perimeter will be :

$18+11+c=44$

$29+c=44$

Subtracting 29 in both sides

$29+c-29=44-29$

$c=15$

Hence the length of third side is 15. Answer

Hope it will help :)

At 2:00 PM a car's speedometer reads 30 mi/h. At 2:20 PM it reads 50 mi/h. Show that at some time between 2:00 and 2:20 the acce

storchak [24]

Answer:

The correct answer will be "60 min/hour".

Step-by-step explanation:

At time 2:00 PM

A car reads = 30 mi/h

At time 2:20 PM

A car reads = 50 mi/h

Now,

At time 2:00 PM

t = 0

At time 2:20 PM

t = $\frac{1}{3}$

$v(0)=30$

$v(\frac{1}{3})=50$

For MVT,

$v'(c)=\frac{v(\frac{1}{3} -v(0))}{(\frac{1}{3} )}$

$=\frac{20}{\frac{1}{3} }$

$=60 \ min/hour$

HELPPPPPPOPPOPPPPP???

z = 106

y = 74

Since angle 74 and angle y are the same sizes, you can know for a fact they are the same measurments. Next, you would do 74(2) and that would get you 148. 360 - 148 is 212. 212/2 is 106. TADAAAAA. That's the answer.

is the same as picking from a points set hmmm, notice the table is an x,y table, so we can just pick any two points to get the slope and thereby the equation.

let's use (100, 36.5) and (300, 106.5)

$\bf (\stackrel{x_1}{100}~,~\stackrel{y_1}{36.5})\qquad (\stackrel{x_2}{300}~,~\stackrel{y_2}{106.5}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{106.5-36.5}{300-100}\implies \cfrac{70}{200}\implies \cfrac{7}{20} \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-36.5=\cfrac{7}{20}(x-100) \\\\\\ y-36.5=\cfrac{7}{20}x-35\implies y=\cfrac{7}{20}x+1.5$

and for this one let's pick say (35, 88) and (45, 82)

$\bf (\stackrel{x_1}{35}~,~\stackrel{y_1}{88})\qquad (\stackrel{x_2}{45}~,~\stackrel{y_2}{82}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{82-88}{45-35}\implies \cfrac{-6}{10}\implies -\cfrac{3}{5} \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-88=-\cfrac{3}{5}(x-35) \\\\\\ y-88=-\cfrac{3}{5}x+21\implies y=-\cfrac{3}{8}x+109$
