Answer:
89 degrees
Step-by-step explanation:
Since these angles make up a triangle, we know that the total of these angles will make 180 degrees. So, we need to set the equations up appropriately, and solve for x:
[tex]180=(4x+1)+(2x-6)+(6x-7)\\180=12x-12\\192=12x\\x=16\\[/tex]
Then, you plug 16 back into the equation for angle J, and simplify:
[tex](6(16)-7)\\(96-7)\\(89)[/tex]
Therefore, the answer is 89 degrees.

In the diagram, point C represents the center of the sphere. Diego says that the part of the sphere labeled D is the radius. Gregoire says that the part of the sphere labeled D is the diameter of the sphere.
A sphere. C is the center and D is the diameter.
Who is correct and why?
Gregoire is correct; the diameter is a chord that passes through the center of the sphere.
Gregoire is correct; the diameter is a chord that is from the center to the surface of the sphere.
Diego is correct; the radius is a chord that passes through the center of the sphere.
Diego is correct; the radius is a chord that is from the center to the surface of the sphere.
Answer:A
Step-by-step explanation: edg 2021
Gregoire is correct; the part of the sphere labeled D is the diameter of the sphere.
What is a sphere?It is a three-dimensional figure where the volume is given as 4/3 πr³
We have,
The diameter of a sphere is a chord that passes through the center of the sphere and has endpoints on the surface of the sphere.
Therefore, the part of the sphere labeled D in the diagram is the diameter, not the radius.
The radius of a sphere is a chord that is from the center to the surface of the sphere, and it is half the length of the diameter.
Thus,
Gregoire is correct; the part of the sphere labeled D is the diameter of the sphere.

What are the resulting coordinates of triangle X′Y′Z′ after rotating triangle XYZ counterclockwise 90° about the origin? Question options:
A) X′ (1, 1), Y′ (1, 4), Z′ (–4, 4)
B) X′ (1, 1), Y′ (4, 1), Z′ (4, 4)
C) X′ (1, 1), Y′ (1, 4), Z′ (4, 4)
D) X′ (–1, 1), Y′ (1, 4), Z′ (4, –4)
Answer:
C
Step-by-step explanation:
Rotation 90 degrees counter clockwise rule (x,y) -----> ( -y , x )
In order to find the answer we must first find the coordinates of the pre image
The coordinates are...
x (1,-1)
y (4,-1)
z (4,-4)
Now we apply the rule stated previously
( The rule explanation: the x and y values swap and the y values sign changes. So if the y value was previously positive, after a 90° counter clockwise rotation, the y value will then be negative)
x (1,-1) -----> swap x and y values ( -1,1) ------> flip sign of new x value ( 1 , 1 )
y (4,-1) ------> swap x and y values ( -1,4) -----> flip sign of new x value ( 1 , 4 )
z (4,-4) -----> swap x and y values ( -4,4) ------> flip sign of new x value ( 4,4)
the new coordinates are X' (1,1) , Y' (1,4) , Z (4,4)
Hence the answer is C

Answer:
Table 1(red)
Step-by-step explanation:
A proportional relationship will have a constant of proportionality between y and x all through the data given.
Constant of proportionality, k = y/x
Table 1 (red):
y/x = 5/1 = 10/2 = 20/4 = 5
k = 5 all through, therefore, this table show a proportional relationship between x and y
Table 2 (blue):
y/x = 1/6 ≠2/9 ≠ 4/15
This doesn't have a constant of proportionality, k, that is the same all through in the given table of values. Therefore, it doesn't show any proportional relationship between x and y

Twelve more than x is greater than
two
A. 12x>2
B. 12/x < 2
C. x + 12>2
D. 12-x>2
Answer:
C. x + 12 > 2
Step-by-step explanation:
Given:
Twelve more than x is greater than two
Required:
Translate to symbols
Solution:
Twelve more than x can be represented as "x + 12"
Greater than is represented by the symbol ">"
Two represented as "2"
Therefore, the translation to symbols would be:
x + 12 > 2
On the same day, Parker’s friend, Peggy, was charged $5 for 1 1/2 lb. of gummy candy. Explain in terms of the graph why this must be a mistake.
Answer:
After a quick online search, I've found that the complete question is:
a) Parker paid $4.50 for three pounds of gummy candy. Assuming each pound of gummy candy costs the same amount, complete the table of values representing the cost of gummy candy in pounds.
Then we want to graph the points, and then comes our question:
c) On the same day, Parker’s friend, Peggy, was charged $5 for 1 1/2 lb. of gummy candy. Explain in terms of the graph why this must be a mistake.
So first, we know that this is a proportional relationship (each pound of candy costs the same)
And 0 pounds of candy should cost $0.
Then the relation between y (price) and x (number of lb) is:
y = k*lb
where k is the cost per lb.
Knowing that Parker paid $4.50 for three pounds of gummy candy, the relation is:
$4.50 = k*3lb
($4.50/3lb) = k = $1.50/lb
Then the linear relation is:
y = ($1.50/lb)*x
Now, in this question we can see that Parker's friend was charged $5 for ( 1 and 1/2) lb of candy.
If we replace those values in the equation, we get:
$5 = ($1.50/lb)*(1 + 1/2)lb = $2.25
This equation is false, then, in terms of the graph, the point ( (1 and 1/2)lb, $5) does not belong on the graph that you found in the previous points.

To graph the function g(x) = (x - 5)² - 9, shift the graph of f(x) = x²
5 units right and 9 units down
Step-by-step explanation:
Let us revise the translation
1. If the function f(x) translated horizontally to the right by h units, then
its image is g(x) = f(x - h)
2. If the function f(x) translated horizontally to the left by h units, then
its image is g(x) = f(x + h)
3. If the function f(x) translated vertically up by k units, then its image
is g(x) = f(x) + k
4. If the function f(x) translated vertically down by k units, then its image
is g(x) = f(x) - k
∵ f(x) = x²
∵ g(x) = (x - 5)² - 9
∴ g(x) = f(x - 5)² - 9
∴ h = 5 ⇒ 5 units right
∴ k = -9 ⇒ 9 units down
∴ f(x) translated 5 units to the right
∴ f(x) translated 9 units down
To graph the function g(x) = (x - 5)² - 9, shift the graph of f(x) = x²
5 units right and 9 units down
The graph of g(x) = -1/5(x + 5)² - 2 is plotted making use of the points it passes.
What is a function?A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.
The given function is g(x) = -1/5(x + 5)² - 2.
In order to plot its graph, consider following values of x and y as follows,
For x = 0,
g(x) = -1/5(0 + 5)² - 2
= -7
For x = -5,
g(x) = -1/5(-5 + 5)² - 2
= -2
Now as the given function has its degree as 2, it is parabolic.
Thus, its graph can be drawn as follows,
Hence, the graph of the given function is drawn clearly.
