Write the equation for a line passing through (4, 13) and has a slope of 3
Answer:
Step-by-step explanation:
y - 13 = 3(x - 4)
y - 13 = 3x - 12
y = 3x + 1
f(x) = (x - 3)(x + 4)
Answer:
f(x)= x^2+x-12
Step-by-step explanation:
FOIL
First= (x)(x)=x^2
Outer=(x)(4)=4x
Inner=(-3)(x)=-3x
Last=(-3)(4)=-12
x^2+4x-3x-12
x^2+x-12
Juan tried 16 free throw attempts playing basketball. He succeeded 9 times what is the experiential probability of not succeeding on his next attempt? write as a fraction
Answer:
The probability of not succeeding next attempt is 7/16
Step-by-step explanation:
Here in this question, we are asked to write the probability of not succeeding in the next attempt given that he attempted 9 success out of 16 trials.
To calculate this probability of not succeeding, we need to get it from the number of unsuccessful throws.
Thus, if 9 throws are successful out of 16, then the number of unsuccessful throws will be 16-9 = 7
So the probability of not succeeding on next attempt will be 7/16

Answer:
11
Step-by-step explanation:
The number 11 is called the base, while the number 12 is called the exponent .
Answer:
11

An exponential has the base at the bottom, or the lower portion. Think of "basement" to help remember this. The exponent is the number up top, so 12 is the exponent.
(x−4) (x-4) is subtracted from 10x
Answer:
18x - x^2 - 16
Step-by-step explanation:
10x - ((x - 4) (x - 4))
10x - (x - 4)^2
10x - (x^2 - 2x · 4 + 4^2)
10x - x^2 + 2x · 4 - 4^2
10x - x^2 + 8x - 16
(10x + 8x) - x^2 - 16
18x - x^2 - 16

given the function f(x)=x^2+9 find f(x-2)
Answer:
x^2 -4x+13
Step-by-step explanation:
f(x)=x^2+9
Replace x with x-2
f(x-2)=(x-2)^2+9
FOIL
f(x-2)=x^2 -2x-2x +4+9
Combine like terms

y = 8500
It is said that the plane loses elevation at a rate of 150 feet per minute.
y = 8500 - 150
We don't know how many minutes the plane has been losing elevation so we use m
y = 8500 - 150m

The least common denominator of the fractions: 7/8 and 1/4.
Answer:
8
Step-by-step explanation:
Since you can divide 4 into 8 evenly, it's the larger of the two - the lowest common denominator is 8.
The least common denominator of the fractions will be 4.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Answer:
|h -1.7| ≤ 0.5
Step-by-step explanation:
Consider the absolute value inequality ...
|x -a| ≤ b
This is fully equivalent to ...
-b ≤ x -a ≤ b
because the value between the absolute value bars can be either positive or negative. If we add a to this, we get ...
-b +a ≤ x b +a
__
Comparing this to your given expression, we find ...
-b +a = 1.2
b + a = 2.2
If we add these equations together, we get ...
0 +2a = 3.4
a = 1.7 . . . . . . . the midpoint of the interval [1.2, 2.2]
b = 2.2 -a = 0.5 . . . . half the width of the interval [1.2, 2.2]
So, your absolute value inequality is ...
|h -1.7| ≤ 0.5
