Answers
Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20

What is the slope of the line that passes through the points (5,4) (6, 0)?
Answers
Answer:
y=-4x+24
Slope is -4
Step-by-step explanation:
1. Use the slope formula to find the slope of the line.
y2-y1/x2-x1
0-4/6-5 = -4/1
Slope = -4
2. Use point-slope to find the equation for the line.
y-y1=m(x-x1)
y-0=-4(x-6)
y-0=-4x+24
3. Simplify to put it in y=mx+b form.
y=-4x+24
What is the solution to the equation 3(2x+5) = 3x+4x

Ox=15
Answers
Answer:
ox=15........ .......
The solution to the equation 3(2x+5) = 3x+4x is x = -5, the correct option is C.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
The equation 3(2x+5) = 3x+4x
Now,
This is because we can simplify the equation by using the distributive property and combining like terms. For example: 3(2x+5) = 3x+4x Expanding, we get: 6x + 15 = 3x + 4x Combining like terms, we get: 6x + 15 = 7x Subtracting 6x from both sides, we get: 15 = x Subtracting 15 from both sides, we get: x = -5
Therefore, by the given equation the answer will be x=-5.

Answers
Answer:
t+f=12
7t+3f=72
Step-by-step explanation:
7pts for t + 3pts for f =72 pts
7t+3f+72
This question is based on the system of equations. Therefore, the t + f = 12 and 7t + 3f =72 are system of equations can be used to determine the number of touchdowns and field goals made in the football game.
Given:
A football team scored 12 times in a game for a total of 72 points. Each touchdown with the extra point is worth 7 points. Each field goal is worth 3 points.
We need to choose the system of equations from the given options can be used to determine the number of touchdowns and field goals made in the football game.
According to the question,
Let t is the number of touchdowns and f is the number of field goals.
It is given that, a football team scored 12 times in a game.
In mathematically expressed as,
⇒ t + f = 12
Each touchdown with the extra point is worth 7 points and field goal is worth 3 points.
In mathematically expressed as,
⇒ 7t + 3f =72
Therefore, the t + f = 12 and 7t + 3f =72 are system of equations can be used to determine the number of touchdowns and field goals made in the football game.

What are the coordinates of the centroid of a triangle with vertices P(−4, −1), Q(2, 2), and R(2, −3)?
Enter your answers in the boxes.
( , )
Answers
Answer:
[tex]G(0, -\dfrac{2}{3})[/tex]
Step-by-step explanation:
Given that:
The coordinates of the vertices of a triangle [tex]\triangle PQR[/tex] are given as:
[tex]P(-4, -1)[/tex], [tex]Q(2, 2)[/tex], and [tex]R(2, - 3)[/tex].
To find:
The coordinates of the centroid of the triangle.
Solution:
The coordinates of the centroid of a triangle is given as:
[tex]G(\dfrac{x_1+x_2+x_3}{3}, \dfrac{y_1+y_2+y_3}{3})[/tex]
Where [tex](x_1,y_1), (x_2,y_2)\ and\ (x_3,y_3)[/tex] are the coordinates of the vertices of the triangle.
As per the given values, we have:
[tex]x_1 = -4\\y_1 = -1\\x_2 = 2\\y_2 = 2\\x_3 = 2\\y_3 = -3[/tex]
Putting the values,we can find the coordinates of centroid as:
[tex]G(\dfrac{-4+2+2}{3}, \dfrac{-1+2-3}{3})\\\Rightarrow G(0, -\dfrac{2}{3})[/tex]
Therefore, the coordinates of the centroid is:
[tex]G(0, -\dfrac{2}{3})[/tex]

A term in a geometric sequence
Step-by-step explanation:
Geometric Sequences
There are two basic types of sequences: arithmetic and geometric. The arithmetic sequences can be recognized because each term is found as the previous term plus a fixed number called the common difference.
In the geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.
We are given the sequence of areas of the copies of a chart as a function of the number of times it was copied.
50%, 25%, 12.5%, 6.25%, ...
It's known the next term will follow the previous sequence. Note the second term is equal to the first term divided by 2. The third term is equal to the second divided by 2 and so on.
a2 = a1/2
a3=a2/2
a4=a3/2
This corresponds to a geometric sequence with common ratio 1/2, thus the answer is:
