The perimeter of a triangle is 42 meters. Side (a) is two less than side (b) and side (c) is triple side (b). What are the lengths of the three sides?
The length of three sides of triangle is,
[tex]a=6.8m\\\\b=8.8m\\\\c=26.4m[/tex]
Perimeter of triangle :Perimeter is the sum of all three sides of triangle.
Let us consider that side b of triangle is x.
Given that, Side (a) is two less than side (b) and side (c) is triple side (b).
So that, sides of triangle are,
[tex]a=x-2\\\\b=x\\\\c=3x[/tex]
Perimeter of triangle are,
[tex]x-2+x+3x=42\\\\5x=44\\\\x=44/5=8.8[/tex]
Side [tex]a=8.8-2=6.8m,b=x=8.8m,c=3x=3*8.8=26.4m[/tex]

Which is the endpoint of a ray?
Opoint R
O points
Opoint T
O point U
Answer:
B-
point s
Step-by-step explanation:
I just did the quiz, this is the correct answer
Point S is the endpoint of the rays.
Option B is the correct answer.
What is a ray?In geometry, a ray is a straight line that starts from a specific point (called the endpoint) and extends infinitely in one direction.
A ray can be thought of as a part of a line that has one endpoint and continues indefinitely in one direction.
We have,
A ray is a line that starts from a specific point and extends infinitely in one direction.
The starting point of the ray is called the endpoint, and the other end of the ray extends indefinitely.
Therefore, a ray does not have an endpoint in the direction it extends, but only at its starting point.
From the figure,
The ray SR, SU, and ST have one common starting point.
i.e Point S.
Thus,
Point S is the endpoint of the rays.

Choose the graph that matches the inequality y <-2x+4.
The graph for the Inequality y <-2x+4 is attached below.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
For example, Olivia is selected in the 12U Softball. How old is Olivia? You don't know the age of Olivia, because it doesn't say "equals". But you do know her age should be less than or equal to 12, so it can be written as Olivia's Age ≤ 12. This is a practical scenario related to inequalities.
Given:
y <-2x+4.
The Inequality shows the shaded region in the Graph.
So, the intercept for the inequality is 4 and slope is of 2 units.
Hence, the graph for the Inequality y <-2x+4. is attached below.

A line passes through the points (-6, 4) and (-2, 2). Which is the equation of the line?
O y--3x+1
O y-5x+7
O y = -2x - 8
O y = 2x + 16
Answer:
[tex]\displaystyle y=-\frac{1}{2}x+1[/tex]
Step-by-step explanation:
The equation of any line in slope-intercept form is:
y=mx+b
Being m the slope and b the y-intercept.
Assume we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Two points are given: (-6,4) and (-2,2). Calculating the slope:
[tex]\displaystyle m=\frac{2-4}{-2+6}=\frac{-2}{4}=-\frac{1}{2}[/tex]
The equation of the line is, so far:
[tex]\displaystyle y=-\frac{1}{2}x+b[/tex]
To calculate the value of b, we use any of the given points, for example (-6,4):
[tex]\displaystyle 4=-\frac{1}{2}(-6)+b[/tex]
[tex]\displaystyle 4=3+b[/tex]
Solving:
b = 1
The equation of the line is:
[tex]\boxed{\displaystyle y=-\frac{1}{2}x+1}[/tex]
We can see none of the choices is correct.

10x − 6 = 24
Answer:
3
Step-by-step explanation:
10x-6=24
10x = 24+6 (You switch sides because you can add 24 and 6. You cannot add 10x to 24 or 6)
10x= 30
x= 30/10
x= 3
The answer is 3.
Answer:
x=3
Step-by-step explanation:
10x-6=24
Subtract 6 from 6 and then add 6 to 24
10x=30
30÷10=3
Divide 30 by 10

A group of hikers is progressing steadily along an uphill trail. The graph shows their elevation (or height above sea level), in feet, at each distance from the start of the trail, in miles.
Answer:
-2
Step-by-step explanation:
Y=500+250x
The graph shows the linear relationship between Elevation in feet and distance along trail in miles.
Intercept = 500 feets Slope = 250 (positive) y = 500 + 250xThe intercept is the point where the regression line intersects the y - axis. From the graph, the intersect is 500 feets From the graph, the slope is positive, as elevation increases with distance. The slope = Rise ÷ Run Slope = (2500 - 500) ÷ (8 - 0)Slope = 2000 ÷ 8Slope = 250The regression equation written in the form :

9. Let p be "an animal is a dog" and let q be "an animal is a golden retriever." Write the conditional statement.
Then decide whether it is true or false.
a. If an animal is a golden retriever, then it is a dog; true
b. If an animal is not a golden retriever, then it is not a dog; false
C. If an animal is a dog, then it is a golden retriever; false
If an animal is not a dog, then it is not a golden retriever; true
Answer:
C. If an animal is a dog, then it is a golden retriever; false
Step-by-step explanation:
Logical reasoning is an important aspect of mathematics.
The conditional statements in the question are represented by the letters p and q. The if-then statement in which the statement p will lead to a conclusion in q is a glaring characteristic of conditional statements. A conditional will be held to be true unless a statement that is true has a false conclusion derived from it.
In the question above, the conditional statement is; If an animal is a dog, then it is a golden retriever. We can clearly see that this conclusion is false.
