my question is -9x-5=-95
Answer:
x=10
Step-by-step explanation:
Pull out like factors :
-9x + 90 = -9 • (x - 10)
Equations which are never true:
2.1 Solve : -9 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
2.2 Solve : x-10 = 0
Add 10 to both sides of the equation :
x = 10
A regular m-gon has 3 times as many sides as a regular k-gon.
The measure of an interior angle of the regular m-gon is 14/3 times
the measure of an exterior angle of the regular k-gon.
Algebraically find the values of k and m.
9514 1404 393
Answer:
k = 10m = 30Step-by-step explanation:
The interior angle of the m-gon is ...
m-interior = 180 -360/m
The exterior angle of the k-gon is ...
k-exterior = 360/k
The required relationships are ...
m = 3k
m-interior = 14/3(k-exterior)
Substituting for m, we can write the latter relation as ...
(180 -360/(3k)) = 14/3(360/k)
Multiplying by 3k/180, we have ...
3k -2 = 28
k = (28 +2)/3 = 10
The values of k and m are 10 and 30, respectively.
_____
Check
The interior angle of the m-gon is 180 -360/30 = 168 degrees.
The exterior angle of the k-gon is 360/10 = 36 degrees.
The angle ratio is 168/36 = 14/3 as required.
Could someone help me solve this problem?
Answer: 18 students would like to learn Spanish
Step-by-step explanation:
Can someone help me? After I figure out the sequence i have to write the formula. please help.
5/6, 2/3, 1/2, 1/3,...
Rewrite the fractions to have a common denominator to find the difference:
2/3 = 4/6
Difference = 4/6-5/6 = -1/6
Sequence formula = an = a1 + d(n-1)
A1 is the first term 5/6
And d = -1/6
Sequence = 5/6 -1/6(n-1)
Simplify to get an =(-n +6)/6
Given p(x), find p(-1) by using synthetic substitution.
p(x)=7x^3-6x^2+39x-104
p(-1)= _______
Answer:
p (-1) = -156
Step-by-step explanation:
Explanation:-
Given polynomial
p(x)=7x³ -6x²+39x-104
Put x=-1
p (-1) = 7 ( -1 )³ - 6 ( -1 )² + 39 (-1 ) - 104
= - 7 - 6 - 39 - 104
p (-1) = -156

A theater is filled with 84 females and 132 males. What percent of the people in the theater are female?
Answer:
look at how I rounded them and put in the answer it says to round to
Step-by-step explanation:
84 + 132 = 216
84 / 216 = 38.88%
rounded to the nearest hundredth = 38.89%
rounded to the nearest tenth = 38.9%
rounded to the nearest whole number = 39%
The percent of the people in the theater are female will be 38.89%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
A theater is filled with 84 females and 132 males.
Now,
Since, A theater is filled with 84 females and 132 males.
Hence, Total number of peoples = 84 + 132
= 216
Thus, The percent of the people in the theater are female will be;
Percent = 84 x 100 / 216
= 38.89%
Therefore, The percent of the people in the theater are female will be 38.89%.

Identify the real and imaginary part of the complex number. 2 + 6i Real:? Imaginary:?
real = 2 imaginary = 6i
there's only two terms in the expression.
i is an imaginary number - it's not on the number line and it never will be; which means any TERM with i in it, is imaginary. 6i is one term so the entire term is imaginary since 6i will never be on the number line.
2 is on the number line which means it's a real number.

Answer:
RS = 11
Step-by-step explanation:
well from the mid-point theorem we have that
[tex]\triangle PRS \sim \triangle PNQ[/tex]
by a ratio of
[tex]1:2[/tex]
so
[tex]\frac{RS}{NQ}=\frac{1}{2}\\\\2[\frac{RS}{NQ}]=2[\frac{1}{2}]\\\\\frac{2RS}{NQ}=1\\\\NQ[\frac{2RS}{NQ}]=NQ[1]\\\\2RS=NQ[/tex]
and now we plug in
[tex]RS = 5x-39\\\\NQ = 4x-18[/tex]
[tex]2[5x-39]=4x-18\\\\10x-78=4x-18\\\\10x-4x=-18+78\\\\6x=60\\\\x=10[/tex]
so the length of RS is
[tex]RS = 5x-39\\\\RS = 5(10)-39\\\\RS=50-39\\\\RS=11[/tex]
A jacket is on sale for $68.00. There is 5% sales tax on the purchase. What is the total cost, including tax?
Answer:
$71.40
Step-by-step explanation:
Before Tax Price: $68.00
Sale Tax: 5.00% or $3.40
After Tax Price: $71.40
Answer:
71.40
Step-by-step explanation:
Sales tax = 5% of 68
[tex]=\frac{5}{100}*68\\\\=\frac{340}{100}\\\\= 3.40[/tex]
Sales tax = $ 3.40
Total cost = 68 + 3.40 = $ 71.40

Sketch a graph of the relationship between cost and pounds of blueberries.
Answer:
Step-by-step explanation:
Which of the following statement(s) describes the rate of change of f over the interval 1.5 ≤ x ≤ 3? Select all that apply.
The graph with the X-coordinate marks 0, 2, and 4. The Y-coordinate mark 0, 2, and 4. There is graph of absolute value function “f” which opens downwards. The function has a vertex at (1, 0). It passes through the points (1.5, 1) and (3, 4).
A. The rate of change is 12.
B. The rate of change is 2.
C. The rate of change is constant.
D. The rate of change is increasing.
Answer:
B. The rate of change is 2.
C. The rate of change is constant.
D. The rate of change is increasing.
Step-by-step explanation:
Rate of change over 1.5 ≤ x ≤ 3:
[tex] rate of change = \frac{f(b) - f(a)}{b - a} [/tex]
Where,
a = 1.5, f(a) = 1,
b = 3, f(b) = 4
Plug in the values:
[tex] rate of change = \frac{4 - 1}{3 - 1.5} = \frac{3}{1.5} = 2 [/tex]
✔️The rate of change = 2
✔️The rate of change is increasing because the value is a positive value.
✔️The rate of change is also constant over 1.5 ≤ x ≤ 3 since the line is straight.
The points on the interval of the absolute value function in the graph are on the same straight line.
The statements that describe the rate of change over the interval; 1.5 ≤ x ≤ 3 are;
B. The rate of change is 2C. The rate of change is constantReasons:
The given parameter of the graph of the f are;
The vertex of the function = (1, 0)
The straight line of the function f passes through the points (1.5, 1) and (3, 4)
Therefore;
[tex]\displaystyle The \ slope \ of \ the \ graph \ between \ (1.5, \, 1) \ and \ (3, \, 4) = \mathbf{\frac{4 - 1}{3 - 1.5} }= \frac{3}{1.5} =2[/tex]
The slope of the graph = The rate of change of the graph
Therefore;
The rate of change of the graph over the interval 1.5 ≤ x ≤ 3 is 2
The rate of change is 2Given that the graph is a straight line graph, we have;
The slope of the graph is constant, therefore;
The rate of change is constantLearn more about the graph of linear functions here:
