What is x? (Triangle Theorems)
1. x = 54
2. x = 9
3. x = 24
4. x = 144
Answer:
2. x = 9
Step-by-step explanation:
The sum of the measures of the angles of a triangle is 180°.
6x + 16 + 90 + 20 = 180
6x + 126 = 180
6x = 54
x = 9
Answer: 2. x = 9

Step-by-step explanation:
Which points are separated by a distance of 6 units? O A. (3, 2) (3,9) O B. (1,5) (1,3) O C. (2,7) (2, 1) O D. (4,1) (4,6)
Explanation:
The x coordinates are the same, so we subtract the y coordinates
7-1 = 6
This shows the points have a distance of 6 units. You can plot the two points and count the numbers of spaces between them to confirm this.

2x-3y=4
2x+8=11
Answer:
x=1.5 y=-1/3
Step-by-step explanation:
2x-3y=4
2x+8=11
Let's subtract 8 from both sides of the second equation:
2x=3
x=1.5
Substituting this into the first equation, we get:
2(1.5)-3y=4
3-3y=4
-3y=1
y=-1/3
Write the next three terms of the arithmetic sequence.
First term:15
Common difference: -4
Answer:
11, 7,3
Step-by-step explanation:
common difference means what you do to the number to get the next term. So 15-4 is 11. Then 11-4=7 and 7-4 is 3
x -10 -3 4 11
y 1 6 30 120
Is the relationship linear, exponential, or neither?
Answer: Option C, neither.
Step-by-step explanation:
Here we have the table:
x: -10 -3 4 11
y: 1 6 30 120
This means that if our function is f(x), then:
f(-10) = 1
f(-3) = 6
f(4) = 30
f(11) = 120
We want to know if this represents a linear equation or an exponential equation or neither.
First, let's try with a linear equation.
We know that a linear equation can be written as:
f(x) = a*x + b
Then let's input the known values and let's see if this equation works.
We can use two of the known points to get:
f(-10) = 1 = a*-10 + b
f(4) = 30 = a*4 + b
With these equations, we can find the value of a and b, once we find these values, we can see if the equation also works for the other two points.
1 = a*-10 + b
30 = a*4 + b
First, we need to isolate one of the variables in one of the equations.
I will isolate b in the first one:
b = 1 + a*10
Now we can replace this in the other one to get:
30 = a*4 + 1 + a*10
30 = 1 + a*14
30 - 1 = a*14
29 = a*14
29/14 = a = 2.07
and using the equation b = 1 + a*10 we can find the value of b:
b = 1 + 2.07*10 = 1 + 20.7 = 21.7
Then the equation we get is:
f(x) = 2.07*x + 21.7
Now we need to see if this works for the other two points:
for x = -3, we need to get: f(-3) = 6
f(-3) = 2.07*-3 + 21.7 = 15.49
We did not get the value we expected, then we already know that the relationship is not linear.
Now let's see if the relationship can be exponential.
An exponential function is written as:
f(x) = A*(r)^x
Let's do the same as above, let's use two of the known points to find the values of A and r
f(-3) = 6 = A*(r)^(-3)
f(4) = 30 = A*(r)^4
Now we have the system of equations:
30 = A*(r)^4
6 = A*(r)^(-3)
If we take the quotient of these two equations, we get:
(30/6) = (A*(r)^4)/( A*(r)^(-3))
5 = (r^4)*r^3 = r^(4 + 3) = r^7
(5)^(1/7) = r = 1.258
And the value of A is given by:
30 = A*(1.258)^4
30/( (1.258)^4 ) = 11.98
Then the exponential equation is something like:
f(x) = 11.98*(1.258)^x
Now let's see if this equation also works for the other two points:
for x = -10, we should get f(-10) = 1
Let's see that:
f(-10) = 11.98*(1.258)^(-10) = 1.2
And for x = 11 we should get f(11) = 120
f(11) = 11.98*(1.258)^(11) = 149.6
So we get values closer to the ones we should get, but not the exact ones, so this is not an exponential relation.
Then the correct option is C, neither.
8th-grade math need help asap
Answer:
C
Step-by-step explanation:
-5(x - 19) ≤ -6 + 2x Remove the brackets on the left
-5x +95 ≤ -6 +2x Add 5x to both sides.
95 ≤ -6 + 2x +5x combine
95 ≤ -6 + 7x Add 6 to both sides
101 ≤ 7x Divide by 7
101 /7 ≤ x
What you do next is both tricky and time consuming. You have to get x on the left and the fraction on the right. So subtract x from both sides. And subtract 101/7 from both sides. They both become minus.
101/7 - 101/7 ≤ -101/7 + x
0 ≤ -101/7+ x Now subtract x from both sides
-x ≤ -101/7 + x -x
-x ≤ -101/7
Now comes the really nasty part. You have to get x > 0 and -101/7>0 That's easy enough. You just multiply both sides by -1
x ≤ 101/7
But when you do that (and this where you have to pay attention) the ≤ becomes ≥
x≥ 101/7

Answer:
do you remeber the slope formula
y2 - y1 / x2 - x1
so pick two points from those 4 points ill pick -2,15 and 0,3
so 3 - 15 / 0 - 2 gives us -12/-2 or a slope of 6/1 or just 6

_______ can be a factor in changing body composition for women between the ages of 20 and 40, with an estimated 40 percent of women gaining excessive weight.
Pregnancy can be a factor in changing body composition for women between the ages of 20 and 40, with an estimated 40 percent of women gaining excessive weight.
Body composition is affected by all the changes a body undergoes. Some may result in positive, while other in negative as side effects.
For a women between age group 20 to 40 face weight gaining problem. Generally this is becuse mostly women are pregnant during this age group and due to the biological changes occured during pregnancy may result in weight gain as a side effect to most of them.

In the diagram below, R is located at (24,0), N is located at (12,18), T is located at (12,6), and E is located at (18,15). Assume that N,K,T,E,I, and B are midpoints. Complete the following table. Vertices S K I B A Coordinates
The midpoint of a segment divides the segment into equal halves
The coordinates of K are: [tex]\mathbf{K = (12,12)}[/tex]The coordinates of I are: [tex]\mathbf{I = (24,24)}[/tex]The coordinates of B are: [tex]\mathbf{B = ( 30,33 )}[/tex]The given parameters are:
[tex]\mathbf{R =(24,0)}[/tex]
[tex]\mathbf{N =(12,18)}[/tex]
[tex]\mathbf{T =(12,6)}[/tex]
[tex]\mathbf{E =(18,15)}[/tex]
K is the midpoint of N and T.
So, we have:
[tex]\mathbf{K = (\frac{N_x + T_x}{2},\frac{N_y + T_y}{2})}[/tex]
This gives
[tex]\mathbf{K = (\frac{12 + 12}{2},\frac{18+ 6}{2})}[/tex]
[tex]\mathbf{K = (12,12)}[/tex]
E is the midpoint of T and I.
So, we have:
[tex]\mathbf{E = (\frac{I_x + T_x}{2},\frac{I_y + T_y}{2})}[/tex]
This gives
[tex]\mathbf{(18,15) = (\frac{I_x + 12}{2},\frac{I_y+ 6}{2})}[/tex]
Multiply through by 2
[tex]\mathbf{(36,30) = (I_x + 12,I_y+ 6)}[/tex]
By comparison
[tex]\mathbf{I_x + 12 = 36.\ I_y + 6 =30}[/tex]
So, we have:
[tex]\mathbf{I_x= 24.\ I_y =24}[/tex]
Hence, the coordinates of I are:
[tex]\mathbf{I = (24,24)}[/tex]
I is the midpoint of E and B.
So, we have:
[tex]\mathbf{I = (\frac{E_x + B_x}{2},\frac{E_y + B_y}{2})}[/tex]
This gives
[tex]\mathbf{(24,24) = (\frac{18 + B_x}{2},\frac{15 + B_y}{2})}[/tex]
Multiply through by 2
[tex]\mathbf{(48,48) = (18 + B_x,15 + B_y)}[/tex]
By comparison
[tex]\mathbf{18 + B_x = 48,\ 15 + B_y = 48 }[/tex]
So, we have:
[tex]\mathbf{B_x = 30,\ B_y = 33 }[/tex]
Hence, the coordinates of B are:
