Find three consecutive even integers if three times the first integer is two times the third.​
drek231 [11]

Using a system of equations, it is found that the three consecutive even integers are -8, -6 and -4.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the three consecutive even integers are represented by:

n, n + 2, n + 4

The first integer is two times the third, hence:

n = 2(n + 4)

2n + 8 = n

n = -8

Thus:

n = -8

n + 2 = -8 + 2 = -6

n + 4 = -8 + 4 = -4

The integers are -8, -6 and -4.

How to find an indefinite integral on a ti 84 plus silver edition?
Arada [10]
If you put the indefinite integral into Y1 for a graph and then place as many numbers in L1(The more the better) and then go into "VARS", "Y-VARS", "FUNCTION" and select "Y1". Then use "Y1(L1)sto>L2" to find all Y values of the indefinite integral and use a regression command to give the equation for the Indefinite Integral.EX:Y1=∫0x(3x^2)dx
L1={−10,−9,−8,−7,−6,−5,−4,−3,−2,−1,0,1,2,3,4,5,6,7,8,9,10}
Y1(L1)→L2
CubicReg using L1 as Xlist and L2 as Ylist

y=ax^3+bx^2+cx+da=1b=0c=0d=0
y=x3

PLEASE HELP!!!!!!!!!
Irina-Kira [14]

Answer:

114

Step-by-step explanation:

The external angle measure is equal to the half of difference between the larger intercepted arc (5x-12) and the smaller intercepted arc (3x)

32 = (5x-12 -3x)/2

combine like terms in parenthesis and multiply both sides by 2

32·2 = 2x-12

multiply 32·2 = 64, and add 12 to both sides

64 + 12 = 2x

add 64+12 = 76, and divide both sides by 2 to isolate x

76/2 = x

38 = x

The measure of arc AB is 3x.

Substitute x for 38

Measure of arc AB = 3x = 3·38 = 114
