139c. Find the coordinates of the point of intersection of the lines. y=1-2x and y=x-5
PLS HELP ASAP
The coordinates of the point of intersection is equal to (3, 5).
What is a point of intersection?In Mathematics, a point of intersection can be defined as the location on a graph where two (2) lines intersect, meet, or cross each other, which is typically represented as an ordered pair containing the point, x-axis and y-axis.
Next, we would solve the given equations simultaneously to determine the coordinates of the point of intersection as follows:
y = 1 - 2x
y = x - 5
Re-arranging the equation, we have:
y + 2x = 1
y - x = -5
Subtracting, we have:
3x = 6
x = 6/2
x = 3.
For y-coordinate, we have:
y + 2x = 1
y + 2(3) = 1
y + 6 = 1
y = 1 - 6
y = -5.

Which diagram shows parallel lines cut by a transversal?
Which graph represents the function f(x)=√x+4-2?
Answer:
the top right graph
Step-by-step explanation:
I assume you mean the function is
f(x) = sqrt(x + 4) - 2
because for your function as you wrote it
f(x) = sqrt(x) + 4 - 2 = sqrt(x) + 2
none of the graphs apply.
to find the correct one we look at some specific points.
like x = 0, and when the square root will be 0 (x = -4).
normally we can see the right graph latest here already, but if not, then we have to pick a few more points.
so,
for x = 0 we get
sqrt(0 + 4) - 2 = 2 - 2 = 0
that means
f(0) = 0
now, when we look at the graphs, we see we are already finished. there is only one graph that goes through (0, 0).

Is r=10q+3 a linear function ?
Answer:
Well, if we consider [tex]r[/tex] as y and [tex]q[/tex] as x.
Step-by-step explanation:
So, typically, a linear function is either represented using function notation
[tex]f(x)=mx+b[/tex]
Or in slope-intercept form
[tex]y=mx+b[/tex]
This question is oddly using the variables r and q in place of y and x. If we replace them to be y and x, it will be a linear equation (because the slope is constantly changing).
But, if you aren't allowed to replace r and q to be y and x, then it isn't a linear function.

What is the equation for the line that passes through the coordinates (-4,-12)and(16,3)
The equation of the line that passes through these coordinates is 3x-4y= 36
How to calculate slope?
If you have the coordinates of two points on a line, you can use the slope formula to determine that line's slope. m=(y2-y1)/(x2-x1), or the ratio of the change in the y values to the change in the x values, is the slope formula.
To find the equation of the line we first have to find the slope which is represented by m.
The slope or m is given by : y₂ - y₁ / x₂ - x₁
thus, m= 3-(-12)/ 16-(-4)
m= 3+12/ 16+4 = 15/20
m= 3/4
The equation of a slope is y-y₁=m (x-x₁)
y- (-12) = 3/4 (x- (-4))
y+12 = 3/4 (x+4)
On solving it further we get:
4y+48= 3x+12
3x-4y= 36

$10,000 for 5 years at 4% interest
Simple interest earned on the principal amount $10,000 for 5 years at 4% interest per year will be $12,000.
As given in the question,
Simple Interest:
The simple interest is an amount that is paid for loan or borrowed money over a certain period at a fixed percentage of borrowed money.
Principal amount:
Principal amount is the money that is taken as loan or borrowed.
Formula of Simple Interest:
Simple interest = Principal amount × Rate × Time
Since,
Principal amount = $10,000
Rate = 4% per year
Time = 5 years
Then,
Simple interest = 10,000 × 4 × 5
Simple interest = $ 12000
Total value after 5 years = $ 12000
Principal amount = $ 10000
Interest Earned = (Total value) - (Principal amount)
Interest Earned = $ 12000 - $ 10000
Interest Earned = $ 2000
Therefore, simple interest earned on the principal amount $10,000 for 5 years at 4% interest per year will be $12,000.

1. how do we change a similar fraction?
2. how do we add the similar fraction?
Answer:
You add similar fraction by adding the numerators together but since the denominators are the same u keep them as they are
1. Similar fractions are those which have the same denominator. To change dissimilar fraction to similar fractions, you express them as a equivalent with a common denominator. For example 2/12, 3/12
2. To add similar fraction one should ensure that both the numerator are same and then add the numerator and put that on the denominator. If there is need to simply the fraction then you should first simplify the fraction.
For example:- 1/4+4/4= 5/4
Here as we see that bot number denominator are same so it's addition is done easily

The graph shows the velocity f(t) of a runner during a certain time interval:
Graph of line segment going through ordered pairs 0, 4 and 4, 8. Graph of another line segment going through ordered pairs 4, 8 and 8, 0. Label on the x axis is time in seconds, and label on the y axis is velocity in meters per second.
Which of the following describes the intercepts on the graph?
The initial velocity of the runner was 4 m/s, and the runner stopped after 8 seconds.
The initial velocity of the runner was 8 m/s, and the runner stopped after 4 seconds.
The initial acceleration of the runner was 4 m/s2, and the runner stopped after 8 seconds.
The initial acceleration of the runner was 8 m/s2, and the runner stopped after 4 second
The description of the intercepts of the Graph segments passing through the points (0, 4), (4, 8), (4, 8) and (8, 0) is given by the option;
The initial velocity of the runner was 4 m/s and the runner stopped after 8 secondsWhat is a velocity time graph?A velocity time graph is a graph that shows how the velocity of an object changes with time
The given information on the graph are;
The coordinates of the points on the Graph of the first line segment = (0, 4) and (4, 8)
On Graph of the second line segment, the coordinates of the points = (4, 8), (8, 0)
The label of the axis of the graph are;
X–axis label = Time in seconds (s)
Y–axis label = Velocity in m/s
Required; The option that gives the description of the intercepts of the graph
Solution; The x and y–intercept are given as follows;
At the x–intercept the y–value is 0, which gives the x–intercept of the graph as the point (8, 0)
Given that the y–value which is the value of the velocity, is 0, it means that the runner stops at the point (8, 0), or after 8 seconds
At the y–intercept, the x–value is 0. The y–intercept is therefore the point (0, 4)
The 0 in the y–intercept means that the time is 0 seconds, which is the starting or initial time, while the 4 means that the velocity is 4 m/s.
Therefore, the y–intercept (0, 4) can be described as the initial velocity of the runner is 4 m/s

Answer:
The initial velocity of the runner was 4 m/s, and the runner stopped after 4 seconds and then again after 8 seconds. Option A is the correct answer
Step-by-step explanation:
The intercepts on the graph can be described as follows:- The y-intercept is the point at which the line intersects the y-axis, and it represents the initial velocity of the runner. In this case, the y-intercept is at (0, 4), which means that the initial velocity of the runner was 4 m/s.- The x-intercept is the point at which the line intersects the x-axis, and it represents the time at which the runner stopped. In this case, there are two x-intercepts: one at (4, 8) and another at (8, 0).
This means that the runner stopped twice, once after 4 seconds and again after 8 seconds.
Therefore, the correct description of the intercepts on the graph is: The initial velocity of the runner was 4 m/s, and the runner stopped after 4 seconds and then again after 8 seconds. Option A is the correct answer.

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All the triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except when otherwise specified, this article discusses the triangles in Euclidean geometry, namely the Euclidean plane.
