Answer:
D infitently Many
Step-by-step explanation:
A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
When Josh babysits, he charges a flat fee of $14 plus an
hourly rate of $9. How long would Josh need to babysit if he
wants to earn $86 in one night?
Answer:
8
Step-by-step explanation
86-14=72 this is the hourly rate before the flat fee is added on. Now you have to divide $72 by $9 to see how many hours josh needs to work. Josh gets paid $9 an hour so he needs to work for 8 hours in order to get $72. Then add the flat fee of 14 and you get $86

Answer/Step-by-step explanation:
First, find the slope (m) of Line L using the points (0, 5) and (2, 1):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 5}{2 - 0} = \frac{-4}{2} = -2 [/tex]
Slope (m) = -2
✔️Since the line is parallel bro Line L, it would also have the same slope value of -2.
We can use the slope (m) and a point (a, b) of the line to find its equation using the point-slope formula, y - b = m(x - a).
Substitute (a, b) = (3, 0), and m = -2 into y - b = m(x + a):
Thus,
✅y - 0 = -2(x + 3)
Rewrite equation in slope-intercept form
y = -2(x + 3)
✅y = -2x - 6
Which which equation is standard form has a graph that passes through the point -4 2 and has a slope of 9/2
Answer:
Equation of straight line that passes through (-4, 2) and has slope 9/2 is
[tex]y-2=\frac{9}{2} (x+4)[/tex]
Step-by-step explanation:
Equation of straight line in point slope form is given as
[tex]y-y_1=m(x-x_1)[/tex] ---------(2)
Here
[tex]m = \frac {9}{2}[/tex] and [tex](x_1, y_1) = (-4, 2)[/tex]
Substituting values in equation (1)
[tex]y-2=\frac{9}{2} (x+4)[/tex]
A national census is mandated by the Constitution of Pakistan to be held every ten years. After the independence of Pakistan in 1947, the first census took place in 1951. Figure 1 reflects the increase in population of Pakistan during last four national census. The increase between 1972 and 2017 could be approximated by a linear function. If in 1972 the population was 65.309 million and as per the census data of 2017 the population was 207.774 million;
a) Determine the estimation function P = f (t), where P equals the population of Pakistan and t equals time measured in years since 1972.
b) Interpret the slope and P intercept
c) According to this function, what will be the estimated population of Pakistan in 2027 census?
Answer:
a) [tex]P(t) = 3166t + 65309[/tex]
b) The slope of 3166 means that each year, the population increases, on average, by 3166 million people.
The P-intercept of 65309 means that the population of Pakistan in 1972 was of 65309 million people.
c) The estimated population of Pakistan in 2027 will be of 239 439 million people.
Step-by-step explanation:
Linear function:
In this question, the linear function for the Population in Pakistan in t years after 1972 is given by the following equation:
[tex]P(t) = mt + P(0)[/tex]
In which P(t) is given in millions of people.
In which m is the slope, that is, the average number by which the population changes each year, and P(0) is the population in 1972.
a) Determine the estimation function P = f (t), where P equals the population of Pakistan and t equals time measured in years since 1972.
In 1972, the population was of 65.309 million. This means that [tex]P(0) = 65.309[/tex].
So
[tex]P(t) = mt + 65.309[/tex]
In 2017, the population was 207.774 million.
2017 - 1972 = 45
This means that [tex]P(45) = 207.774[/tex]. So
[tex]207774 = 45m + 65309[/tex]
[tex]45m = 207774 - 65309[/tex]
[tex]m = \frac{(207774 - 65309)}{45}[/tex]
[tex]m = 3166[/tex]
So
[tex]P(t) = 3166t + 65309[/tex]
b) Interpret the slope and P intercept
Following the explanation before item a:
The slope of 3166 means that each year, the population increases, on average, by 3166 million people.
The P-intercept of 65309 means that the population of Pakistan in 1972 was of 65309 million people.
c) According to this function, what will be the estimated population of Pakistan in 2027 census?
2027 - 1972 = 55
So this is
[tex]P(55) = 3166*55 + 65309 = 239 439[/tex]
The estimated population of Pakistan in 2027 will be of 239 439 million people.

WORTH 65 PTS PLEASE ANWSER AS SOON AS POSIBLE The ratio between the number of girls and the number of boys in a school is 3 : 4 if the number of boys is 140, find the number of girls
Answer:
105 girls
Step-by-step explanation:
The ratio between girls and boys is 3:4, which means for every 3 girls, there are 4 boys. We are trying to solve for the number of girls, so the ratio will be x:140. First let's divide 140 by 4 to find out the value of each part.
We will get 35 for each part.
Multiply 35 by 3 to get 105. There we find that there are 105 girls for 140 boys. Hope this helped :)
Image P is shown in the coordinate grid Image P is translated 2.5 units to the right and 3.5 units up to create image P'.
6
Image P
1
2 3
4
Which rule describes this transformation?
Answer:
Here we do not have the image P, but let's solve this in a general way.
Suppose that we have a point A (x,y)
If we translate the point A n units horizontally (where n can be positive, translation to the right, or negative translation to the left.)
The new point will be (x + n, y)
if we translate the point m units vertically (if m is positive the translation is upwards, if m is negative the translation is downwards), the new point will be (x + n, y + m)
Then if our figure was p (x, y)
The new figure is p(x + 2.5, y + 3.5)
So for every point in the figure, we need to add 2.5 to the x component, and 3.5 to the y-component.

Why is a sample used more often more than a population
Answer:
A number which describes a characteristic of a population. ... Uses a sample to find conclusions, analyzations, and probability about a population. Why is a sample used more often than a population? Because it is more difficult to get an accurate population where as a sample is smaller and easier to assess.

graph -3x+y=10 using slope-intercept form
I graphed it using slope-intercept form.
Answer:
Slope-intercept form: (y=mx+b) y=3x+10
To graph, place points at (-2, 4), (-3, 1), and (-4, -2), then draw a line connecting them
Step-by-step explanation:
The 10 in the equation represents where the line will intercept the y-axis. The 3x means that for every 1 unit you move to the right, you move 3 units up (or 1 to the left, 3 units down).
