Given segment AX with point Q between A and X. AX = 25. AQ = 2y + 1. QX = 3y - 1.
We can set up an equation to solve for y using the fact that
y =
AQ =
QX =
Q
Answer:
y=5
AQ=11
QX=14
Q is not a midpoint
Step-by-step explanation:
A line segment can be divided into equal or unequal segments
The values of x, AQ and QX are 5, 11 and 14.
The given parameters are:
[tex]\mathbf{AX = 25}[/tex]
[tex]\mathbf{AQ = 2y + 1}[/tex]
[tex]\mathbf{QX = 3y - 1}[/tex]
[tex]\mathbf{AX = 25}[/tex] can be rewritten as:
[tex]\mathbf{AQ + QX =25}[/tex]
Substitute values for AQ and QX
[tex]\mathbf{2y + 1 + 3y - 1 =25}[/tex]
Execute like terms
[tex]\mathbf{5y =25}[/tex]
Divide both sides by 5
[tex]\mathbf{y =5}[/tex]
Substitute 5 for y in [tex]\mathbf{AQ = 2y + 1}[/tex] and [tex]\mathbf{QX = 3y - 1}[/tex]
[tex]\mathbf{AQ = 2 \times 5 + 1 = 11}[/tex]
[tex]\mathbf{QX = 3 \times 5 - 1 = 14}[/tex]
Hence, the values of x, AQ and QX are 5, 11 and 14.

How do you describe a graph?
For most graphs, give a brief description including the title and axis labels, and mention trends not already described in the text. For simple charts, state the actual data points. For more complex charts, an ideal description would include the data in a table or list.

I've been stuck on this for so long
y = 6/5x - 1
hope this helps :) !!
Answer:
[tex]y = \frac{6}{5}x - 1[/tex]
Step-by-step explanation:
use the formula
[tex]y = mx + b[/tex]
m is the slope and b is the y-intercept. Begin with b, where the line crosses the y-axis (vertical axis). It crosses at -1, so this is b.
Next move with m. Do rise/run. Start at the y-intercept and you are going to rise 6 and run 5 to the next point. So the slope is 6/5. Leave as an improper fraction. Plug-in for m. Since the line goes uphill from left to right it has a positive slope.
If I roll 2 dice, what is the
probability that their total is a

Answer:
The logic is there are six sides to each die, so for each number on one die you can pair with six different numbers on the other die. Therefore, the probability of rolling a prime number on two dice is 15/36, which reduces to 5/12

The total entrance fee for a group of 4 adults and 3 children to a water park is $220. The total fee for a group of 2 adults and 1
child is $98. Determine the entrance fee for an adult and the entrance fee for a child.
a. Select the system of equationslokat model the situation. Solve by using substitution.
Answer:
A.
Step-by-step explanation:
The entrance fee of an adult is equal to $37 and the entrance fee of a child is equal to $24.
What is a system of equations ?
A system of equations is a set or collection of equations that you deal with all together at once.
It is given that :
The total entrance fee for a group of 4 adults and 3 children = $220
and
The total entrance fee for a group of 2 adults and 1 child = $98
Let's assume that the entrance fee for an adult is x and entrance fee for a child is y.
So , the equations can be written as :
4x + 3y = $ 220 --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 1
2x + y = $ 98 --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 2
Now , multiply equation 2 by 2 :
4x + 2y = $ 196 --- --- --- --- --- ---- ---- ---- ------ ----- ----Equation 3
Subtracting equation 3 from equation 1 , we get :
(4x - 4x) + (3y - 2y) = $220 - $ 196
y = $24
or entrance fee of a child is $24.
Now , substituting the value of y in equation 1 , we get :
4x + 72 = $220
4x = 148
x = $37
or entrance fee of an adult is $37.
Therefore , the entrance fee of an adult is equal to $37 and the entrance fee of a child is equal to $24.

when writing the equation of a line in slope-intercept form, how can you determine the value of m in y=mx+b if you know the coordinates of two points on the line?
To determine the value of m in the equation, apply the slope formula, m [tex]= \frac{y_2 - y_1}{x_2 - x_1}[/tex].
How to Determine the Slope of a Line?The slope of a line (m) = change in y / change in x = (y2 - y1)/(x2 - x1).
In the slope-intercept form of an equation that represents a line, the slope is represented as "m" in y = mx + b.
The equation we can use to determine the slope (m) if we are given two points on a line is, m = (y2 - y1)/(x2 - x1).
For example, if two points, (-4,2) and (8,5) are points on the line, we can find the value of the slope (m) as:
m = (2 - 5)/(-4 - 8) = -3/-12
Slope (m) = 1/4
The value of m to use in the equation of the line would be 1/4.

A flat fee of $15.25 plus $3.45 per pound of supplies ordered is added to the bill to cover the shipping cost.The teacher budgets $49.75 for the shipping cost.Which list of values best represents the entire domain for shipping, f(x), as a function of the number of whole pounds of school supplies the teacher can order, x?
The domain of a function is the set of possible input value, the function can take.
The domain is [0,10]
The given parameters are:
[tex]Flat\ Fee = 15.25[/tex]
[tex]Rate = 3.45[/tex]
So, the function f(x) is:
[tex]f(x) = Flat\ Fee + Rate \times x[/tex]
[tex]f(x) = 15.25 + 3.45 \times x[/tex]
[tex]f(x) = 15.25 + 3.45x[/tex]
Because x represents the number of orders, the value of x cannot be negative.
The teacher budgets $49.75.
This means that: f(x) = 49.75
So, we have:
[tex]49.75 = 15.25 + 3.45x[/tex]
Collect like terms
[tex]49.75 - 15.25 = 3.45x[/tex]
[tex]34.5 = 3.45x[/tex]
Divide both sides by 3.45
[tex]10 = x[/tex]
Rewrite as
[tex]x = 10[/tex]
Hence, the domain is [0,10]

Answer:
t = 128°
Step-by-step explanation:
A triangle equals 180°. 2/3 of the angles in the triangle are given, so we would then do the following:
180 - (61 + 67) = x
180 - 128 = x
52 = x
Since a straight line also is 180°, this would mean x + t = 180.
x = 52
We would then convert the equation to the following:
180 - 52 = t
128 = t
The angle "t" is a 128° angle.

use the compound interest formula
I=P(1+r/100)<n
2786=2000(1+4.6/100)^n
divide 2000 by both side
1.393=(1+4.6/100)^n
1.393=1.046^n
introduce the log
log1.393=rlog1.046
divide both with log1.046 to get the value of n
n=7.4
