Solve for X Please walk me through the steps, I understand most of it I just forgot how to do it

nadya68 [22]

Answer:

x=8

Step-by-step explanation:

first you need to find the unknown corner so you do 180-71= 109

then find the interior angle degree (n-2)*180 (n=number of sides) so (4-2)*180=2(180)=360

then set everything equal to 360:

10x+6+13x-2+8x-1+109=360

(combine like terms)

31x+112=360

(subtract 112 form both sides)

31x=248

(divide both sides by 31)

x=8

The table represents the function f(x).

Irina18 [472]

Step 1

Find the slope of the function f(x)

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

Let

$A(-6,0)\\B(0,4)$

substitute

$m=\frac{4-0}{0+6}$

$m=\frac{4}{6}$

$m=\frac{2}{3}$

Step 2

Find the y-intercept of the function f(x)

The y-intercept is the value of the function when the value of x is equal to zero

in this problem the y-intercept of the function is the point $B(0,4)$

the y-intercept is equal to $4$

Step 3

Verify each case

we know that

the equation of the line into slope-intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

case A) $f(t)=t+4$

In this case we have

$m=1\\y-intercept=4$

therefore

the function of case A) does not have the same slope as the function f(x)

case B) $f(t)=t-6$

In this case we have

$m=1\\y-intercept=-6$

therefore

the function of case B) does not have the same slope and y-intercept as the function f(x)

case C) $f(t)=\frac{2}{3}t+4$

In this case we have

$m=\frac{2}{3}\\y-intercept=4$

therefore

the function of case C) does have the same slope and y-intercept as the function f(x)

case D) $f(t)=\frac{2}{3}t+6$

In this case we have

$m=\frac{2}{3}\\y-intercept=6$

therefore

the function of case D) does not have the same y-intercept as the function f(x)

therefore

the answer is

$f(t)=\frac{2}{3}t+4$

The sum of three consecutive odd integers is 75. Find the integers.

makkiz [27]

Answer:

23, 25, and 27.

Step-by-step explanation:

Let the first odd integer be k.

Since the three numbers are consecutive odd integers, the second is given by (k + 2) and the third by (k + 4).

Their sum is 75. Hence:

$k + (k + 2) + (k + 4) = 75$

Solve for k. Combine like terms:

$3k + 6 = 75$

Subtract:

$3k = 69$

And divide:

$k = 23$

Therefore, the first number is 23.

In conclusion, the three consecutive, odd integers are 23, 25, and 27.
