I don’t know how to solve this it’s exponents.
Answers
Answer:
9^6
Step-by-step explanation:
When dividing exponents with the same base, we subtract the exponents
a^b/ a^c = a^(b-c)
9^11/9^5 = 9^(11-5)
= 9^6

Answer:
standard form is 45x -12y -100 = 0.
Step-by-step explanation:
Given the equation is -3/2x=-2/5y-10/3.
Finding common denominator, L.C.M.(2,5,3) = 30.
Multiplying both sides by 30.
30*(-3/2x) = 30*(-2/5y-10/3)
-45x = -12y -100
Moving all terms on left side, keeping right side equal to 0.
-45x +12y +100 = 0
Making x's coefficient positive by changing all signs.
45x -12y -100 = 0
Hence, standard form is 45x -12y -100 = 0.
Answer:
Step-by-step explanation:
You want to rewrite the equation
Ax +By=C A,B,C are integers
30(-3/2x) = 30(-2/5y-10/3)
-45x = -12y - 100
-45x + 12y = -100

B & D
Step-by-step explanation:
The quadratic formula can be used to solve for x for any quadratic. Recall a quadratic is any function whose highest exponent known as degree is 2. Looking at the answer selections, A has one term with exponent 3. This isn't possible in the formula. Looking at answer C, the term with exponent 2 has the same coefficient on each side of the equal sign. When it is rearranged these will cancel out no exponent of 2 will be in the equation anymore. Only B & D work after being rearranged and simplified
The two equations after simplifying will give quadratic equations are:-
x ²-6x-7=2x² and 5x²-3x+10=2x².
What is a quadratic equation?
The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.
Solving for the quadratic equation:-
Option B:-
x ² - 6x - 7 = 2x²
- 2x² + x ² - 6x - 7 = 0
x ² + 6x + 7 = 0
Option D:-
5x² - 3x + 10 = 2x².
5x² - 2x². - 3x + 10 = 0
3x² - 3x + 10 = 0
Therefore two equations after simplifying will give quadratic equations are- x ²-6x-7=2x² and 5x²-3x+10=2x².

Option B:
Equation of the line of best fit in slope-intercept form is .
Solution:
Take two points on the line (0, 1) and (4, 3).
So, .
Slope of the line:
y-intercept means the point which crosses at y-axis.
Here the point on the y-axis is (0, 1).
y-intercept (b) = 1
Slope-intercept form:
y = mx + b

The median is 37 and the range is 29.
First arrange the numbers in order from smallest to largest.
27, 29, 42, 48, 56
The median is 37 so the unknown number must fall between 29 and 42.
27, 29, ___ , 42, 48, 56
Because there are 6 numbers there is no middle number. The median will be the average of the 3rd and 4th number.
Let the unknown number be X
(X + 42) divided by 2 = 37
X + 42 = 74
X = 32
The range is from 27 to 56 which is 29
