Point (1,5) is a solution of the equation g(x)=3x+2 and point (1,5) is not a solution of equation f(x)=|x-1|+1

Why point (1,5)<em> </em>is solution of the equation<em> </em>g(x)=3x+2 ?

If point (1,5) is solution of the equation then they must satisfy the equation.

So we need to check one by one

(x,y)=(1,5)

equation g(x)=3x+2

We can write as

y=3x+2\\5=3*1+2\\5=5

So  point (1,5) is solution of this equation.

Equation f(x)=|x-1|+1

We can write as

y=|x-1|+1\\5=|1-1|+1\\5=0+1\\5\neq 1

So point (1,5) is not solution of equation f(x)=|x-1|+1

An obtuse triangle has two angles 45 n 18 ,and a third unknown angle theta what's the value of the unknown angle​
zlopas [31]

<u>Answer:</u>

An obtuse triangle has two angles 45 and 18. The value of the unknown angle is 117^{\circ}

<u>Solution:</u>

Given that two angles of an obtuse triangle is 45 and 18.  

Third angle is θ  

We are asked to find the value of third unknown angle theta

According to <em>angle sum property of triangle</em>, sum of three angles of triangle is 180^{\circ}

This means in our case sum of 45, 18 and θ should be 180^{\circ}

\begin{array}{l}{=>45+18+\theta=180} \\ {=>\theta=180-63=117^{\circ}}\end{array}

Hence value of unknown third angle of an obtuse triangle is 117^{\circ}

Mrrafil [7]

Answer:

10.14 years

Step-by-step explanation:

The following equation describes the percentage of all eligible voters that are registered to vote as a function of time:

V=100-30e^{-0.04t}

The time 't' for which V(t) = 80 is the amount of years required for the percentage of registered voters to reach 80%:

80=100-30e^{-0.04t}\\\frac{20}{30}= e^{-0.04t}\\ln(\frac{2}{3})=-0.04t*ln(e)\\ t=10.14\ years

It will take 10.14 years until 80% of all eligible voters in your county are registered to vote

How many gallons are in 8 1/4?
wlad13 [49]

The total number of gallons in 8.25 quartz is 2.0625 gallons

<h3>Conversion of gallons to quartz</h3>

According to the given question, we are to convert 8 1/4 quartz to gallons

According to the standard conversion

1 gallons = 4 quarts

x = 8.25 quartz

Take the ratio

1/x = 4/8.25
4x = 8.25

x = 8.25/4

x = 2.0625 gallons

Hence the total number of gallons in 8.25 quartz is 2.0625 gallons

What is the value of x? Also show work pls
drek231 [11]

Answer:

x = 34

Step-by-step explanation:

The angles are corresponding angles and corresponding angles are equal if the lines parallel

2x+3 = 71

Subtract 3 from each side

2x+3-3 = 71-3

2x = 68

Divide by 2

2x/2 = 68/2

x = 34
