Answer:
AC = 23
Step-by-step explanation:
Assuming A, B, and C are on a line with B in the middle...
We know that AB + BC = AC. Travelling from A to C is the same as travelling from A to B, then B to C, as B is on the way between A and C.
Knowing this, we can set up this equation and add the 2 numbers we know:
AC = AB + BC
AC = 11 + 12
AC = 23
Let f(x) = 3x² - x, find f(-3) *
Answer:
30
Step-by-step explanation:
if f(x)=3x^2 - x then,
f(-3)=3*-3^2 -(-3)
=3*9 +3
=27+3
=30
So, The value of f(-3) is 30

The perimeter of a playing field for a certain sport is 334ft. The field is a rectangle, and the length is 47 ft longer than the width. Find the dimensions.
Answer:
The dimensions of the rectangle = 60ft by 107ft
Where 60 ft = Width of the playing field
107ft = Length of the playing field
Step-by-step explanation:
A playing field is Rectangular is shape, hence,
The formula for Perimeter of a rectangle = 2(L + W)
P = 334 ft
L = 47 + W
W = W
Hence we input these values in the formula and we have:
334 = 2(47 + W + W)
334 = 2(47 + 2W)
334 = 94 + 4W
334 - 94 = 4W
240 = 4W
W = 240/4
W = 60
There fore, the width of this playing field = 60 ft
The length of this rectangle is calculated as:
47 + W
47 + 60
= 107 ft
The length of this playing field = 107ft
Therefore the dimensions of the rectangle = 60ft by 107ft

Step-by-step explanation:
Two angles are supplementary. One angle is 184° less than three times the other. Find the measures of the angles.
91°, 89°
96°, 84°
86°, 94°
90°, 86°
Answer:
91°, 89°Step-by-step explanation:
The sum of suplementary angles is allways 180°
so:
x - the other angle
3x - three times the other angle
180°- x - one angle
180° - x + 184° = 3x
364° = 4x
x = 91°
180°- x = 180° - 91° = 89°
what are LOGARITHMS...???
Step-by-step explanation:
A logarithm is a mathematical operation that determines how many times a certain number, called the base, is multiplied by itself to reach another number. ... Logarithms even describe how humans instinctively think about numbers.
Answer:
A logarithm tells what exponent (or power) is needed to make a certain number, so logarithms are the inverse (opposite) of exponentiation. Just as an exponential function has three parts, a logarithm has three parts. The three parts of a logarithm are a base, an argument (also called power) and an answer.

Last year, Kenia got a 350 on her 6th Grade Math EOG. This year Kenia earned a 399, which was a high enough score to make a Level 4. What was the percent of increase in Kenia's score?
Answer:
14%
Step-by-step explanation:
Last year's score = 350
This year's score = 399
What was the percent of increase in Kenia's score
Percentage increase= (new score - old score) / old score × 100
= (399-350) / 350 × 100
= 49 / 350 × 100
= 0.14 × 100
= 14%
The percent of increase in Kenia's score is 14%

5) Alex's house (point F) lies on the same street as her school (point H). Alex's bus stop (point G) lies between her
house and her school. Given FG equals (2x) meters, GH = 1,000 meters, and FH equals 1.200 meters, what is z?
Answer:
Answer:
100 meters
Step-by-step explanation:
Given the following :
Alex house = F
Alex school = H
Alex bus stop = G
FG = 2x meters
GH = 1000meters
FH = 1200 meters
Hence,
FH = FG + GH
1200 = (2x + 1000) meters
1200 = 2x + 1000
1200 - 1000 = 2x
200 = 2x
x = 100meters
Hence, x = 100 meters

Marcus is skiing. He is 869 1/10 get up the mountain. He descends to 450 7/10 feet. What is his change in elevation
Answer:
418 4/10
Step-by-step explanation:
To answer this we subtract 450 7/10 from 869 1/10.
We must borrow a '1' from 869 1/10: 868 11/10
Now subtract 450 7/10 from 868 11/10:
418 4/10 (CHANGE IN ELEVATION)
This reduces to 418 2/5.
POSSIBLE POIN The value of the expression is (Do without a calculator. Leave your answer as a reduced improper fraction and use "" as your fraction bar.)

What is the value of x in the equation −x = 3 − 4x + 15?
Answer:
x = 6
Step-by-step explanation:
First of all you should collect like terms
-x = 18 - 4x
Then you should move the variable to the left
-x + 4x = 18
After that you should collect like terms
3x = 18
Finally divide both sides by 3
x = 6

Given: {(−2, 3), (−1, 2), (0, 2), (−2, 9)}. Is this relation a function? Explain.
Answer:
No
Step-by-step explanation:
(-1,2) and (0,2) have the same y value. Functions cannot share the same y value
The relationships represents by {(−2, 3), (−1, 2), (0, 2), (−2, 9)} is not function.
Given that, {(−2, 3), (−1, 2), (0, 2), (−2, 9)}. Is this relation a function is to be specified.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
In the relation {(−2, 3), (−1, 2), (0, 2), (−2, 9)}
(−2, 3), (−2, 9) are two pairs that show two images of one pre-image that why it is not a function.
Thus, the relationships represents by {(−2, 3), (−1, 2), (0, 2), (−2, 9)} is not function.
