HELP ME PLEASEEEEEEE

Mathematics
1 answer:
Finger [1]3 years ago
5 0

Answer:

x = 6

Step-by-step explanation:

Using the exterior angle theorem

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

79° is an exterior angle of the triangle , then

8x - 13 + 9x - 10 = 79

17x - 23 = 79 ( add 23 to both sides )

17x = 102 ( divide both sides by 17 )

x = 6

What are the vertical asymptotes of the function f(x) =5x+5/x2 + x-2
katen-ka-za [31]

let's recall that the vertical asymptotes for a rational expression occur when the denominator is at 0, so let's zero out this one and check.

\bf \cfrac{5x+5}{x^2+x-2}\qquad \stackrel{\textit{zeroing out the denominator}~\hfill }{x^2+x-2=0\implies (x+2)(x-1)=0}\implies \stackrel{\textit{vertical asymptotes}}{ \begin{cases} x=-2\\ x=1 \end{cases}}

What number Multiplied by 0.5, Multiplied by 3, Square the number, Add 1 equals 50?​
kkurt [141]

Answer:

Step-by-step explanation:

first step: 0.5 * x

second step: 3* (0.5x) = 1.5x

third step: (1.5x)^2

fourth step: (1.5x)^2 + 1 = 50

(1.5x)^2 + 1 = 50                    Subtract 1 from both sides

(1.5x)^2 = 49                          Take the square root of both sides

1.5x = sqrt(49)

1.5x = +/- 7

1.5x = +7

x = 7/1.5

x = 4.67

1.5x = - 7

x = - 7 / 1.5

x = - 4.67

What is 20% off of 35
vodomira [7]
An easy way to find the precentage to to tuen the precentage to a decimal, in this case 20%=0.2, now multiply 35 by 0.2

35x0.2=7!

So 20% of 35 is 7$!

Another way to solve is to take 10% of 35, which you can find by just movig over the decimal (35-$3.50) now just add it together! 3.5+3.5=7$!!


Hope I helped!
