M is the midpoint of AB, AM=3x+3 and AB=8x-6 What is the length of MB

Mathematics

Xelga [282]3 years ago
8 0
If it's the midpoint then MB=3x+3, but to find length set AM equal to one half AB
3x+3=(8x-6)(1/2) or 2(3x+3)=8x-6

2(3x+3)=8x-6
6x+6=8x-6
12=2x
X=6

Which function is not a translation of f(x)=x2+17? f(x)=−x2−17 f(x)=(x−4)2 f(x)=(x+12)2 f(x)=(x−4)2+17
ruslelena [56]
F(x) = -x²-17 is not a translation.

A translation of this graph would either have something added to/subtracted from the end of the function (the c value) or something added or subtracted to x before it is squared.  f(x) = -x²-17 is a reflection, as the coefficient of x² is negative.

Every other choice has something either added to or subtracted from either x before it is squared or from the end.

If m∠ACB = 36, find the area of the shaded sector.
velikii [3]
Answer: 7.85

Explanation: The formula you would use to find the area for the shaded sector is

degree / 360 • 3.14 • r^2

36 / 360 • 3.14 • 5^2

You would square it because we’re looking for area.

X + 2y = 5<br> y = 6x + 3
ki77a [65]

Answer:

x = −1/13 and y = 33/13 or 2 7/13

Step-by-step explanation:

x+2y=5

x+2(6x+3)=5

x+12x+6=5

13x+6=5

-6        -6

13x= -1

/13     /13

<u>x= -1/13</u>

y=6x+3

y=6(-1/13)+3

y= 33/13

y= 2 7/13

The product of two positive consecutive integers is 24 more than 6 times the first number.
STALIN [3.7K]

Answer:

The product of two integers is 72.

Step-by-step explanation:

Let,

x and x+1 be the two consecutive positive integers.

According to given statement;

The product of two positive consecutive integers is 24 more than 6 times the first number.

x(x+1) = 6x+24

x^2+x=6x+24\\x^2+x-6x-24=0\\x^2-5x-24=0\\x^2-8x+3x-24=0\\x(x-8)+3(x-8)=0\\(x-8)(x+3)=0\\

Either,

x-8 = 0

x=8

Or,

x+3 = 0

x=-3

As the integer is positive, therefore, the two integers are 8 and 9.

Product of two integers = 8*9 = 72

Hence,

The product of two integers is 72.
