find the measure of angle J .will mark brainiest
Answer:
<J=51°
Step-by-step explanation:
3x-2+4x-9+3x-9=180
10x-20=180
10x=200
x=20
<J=3x-9=3(20)-9=60-9=51°
Answer: Angle J = 51°
Step-by-step explanation: All angles add up to 180° in a triangle, so add every angle and set it equal to 180°.
(3x - 2) + (3x - 9) + (4x - 9) = 180
Add like terms:
10x - 20 = 180
Add 20 to both sides:
10x = 200
Divide both sides by 10:
x = 20
Now, plug x into angle J:
3(20) - 9
60 - 9
51
Angle J = 51°

Answer:
$3,221.02
Step-by-step explanation:
Month 1: $2000 x 1.10 = $2,200
Month 2 = $2,200 x 1.10 = $2,420
Month 3 = $2,420 x 1.10 = $2,662
Month 4 = $2,662 x 1.10 = $2,928.2
Month 5 = $2,928.2 x 1.10 = $3,221.02

b) cereal if 31 ounces cost $1.50 and 16 ounces cost $0.77.
c) soda if 3 cans cost $1.77 and 5 cans cost $1.79.
PLEASE HELPPP
Answer:
A. 12 oz. for $1.47
B. 16 oz for $0.77
C. 5 cans for 1.79
Step-by-step explanation:
A. Divide them both, cost by quantity.
0.99/8=0.123
1.47/12=0.1225
The second option is better since its 0.005 less than the first option.
B. Again, divide both options.
0.77/16=0.04125
1.50/31=0.04838
Second option because it is 0.00713 cents cheaper.
C. 1.77/3=0.59
1.79/5= 0.36
Second option is .23 cents cheaper than the first option.

What 2 numbers have a difference of 8
Step-by-step explanation:
10-2=8 has the difference of 8
The difference of two numbers is obtained using the subtraction operation ; Hence, two numbers whose difference gives a value of 8 are 16 and 8.
There are many possible values where, the value of the two numbers will give a value of 8.
They include;
10 - 2 = 816 - 8 = 812 - 4 = 813 - 5 = 89 - 1 = 8Therefore, two numbers whose difference gives a value of 8 are 16 and 8.

A phone company charges a base fee of $12 per month plus an additional charge per minute. The monthly phone cost LaTeX: CC can be represented by this equation: LaTeX: C=12+a\cdot mC = 12 + a ⋅ m , where LaTeX: aa is the additional charge per minute, and LaTeX: mm is the number of minutes used. Which equation can be used to find the number of minutes a customer used if we know LaTeX: CC and LaTeX: aa?
Answer: M=(c-12)-a

How do you write 1.65x10^8: 2x10^3 in scientific notation?
I'm guessing you're talking about the ratio,
(1.65 x 10⁸) / (2 x 10³)
You can cancel the lowest power of 10:
(1.65 x 10⁸) / (2 x 10³) = (1.65 x 10⁵) / 2
Divide 1.65 in half to get 0.825. So we have
(1.65 x 10⁸) / (2 x 10³) = 0.825 x 10⁵
Move the decimal point to the right, which involves multiplying by a factor of 10 which is taken from 10⁵, so we end up with
(1.65 x 10⁸) / (2 x 10³) = 8.25 x 10⁴
Linear combination of matrices .
Multiplying a matrix by a scalar is equivalent to multiplying each entry in the matrix by that scalar:

[tex]B=\begin{bmatrix}-2&-6\\2&5\end{bmatrix}\implies-6B=\begin{bmatrix}12&36\\-12&-30\end{bmatrix}[/tex]
Now combine them:

I have a math test please give me the right answer!!
Answer:
-207
Step-by-step explanation:
Using r= -3, we can substitute r in the whole equation as (-3) which gives you: ((-3)-3)^3 +(-3)^2. Now you can calculate these values in a step by step manner. (-6)^3 +9 then to -216 +9 which brings you to the answer of -207.
Answer:

(r - 3)³ + r² if r = -3 and s = -4
(-3 - 3)^3 + (-3)^2
(-6)^3 + (9)
(-6 x -6 x -6) + 9

Which statement correctly describes the relationship between the graph of f(x) and the graph of g(x)=f(x)−4?
The graph of g(x) is the graph of f(x) translated 4 units down.
The graph of g(x) is the graph of f(x) translated 4 units right.
The graph of g(x) is the graph of f(x) translated 4 units up.
The graph of g(x) is the graph of f(x) translated 4 units left.
Answer:
The graph of g(x) is the graph of f(x) translated 4 units down.
Explanation:
Given the function f(x) and g(x) = f(x)-4
This means that the function g(x) is 4 less than the function g(x) i.e the function g(x) is reduced by 4. Since the negative values on a graph are located from the origin down the negative y axis and towards the negative x axis, we can conclude that the graph g(x) translated 4 units down. of f(x). This is translated along the y axis because the function g(x) serves as the output for all values on input variable x.
The g(x) can be written as a function of y i.e we can rewrite it as y = f(x)-4.
Hence the correct option is The graph of g(x) is the graph of f(x) translated 4 units down.

Option (4)
Step-by-step explanation:
From the figure attached,
Lines 'c' and 'd' are the parallel lines a transversal line is intersecting these lines.
m∠2 = 124° [Corresponding angles]
m∠7 = 124° [Vertically opposite angles]
m∠2 = m∠3 = 124° [Vertically opposite angles]
Therefore, angles ∠2, ∠7 and ∠3 measure 124°.
