A student analyzed the table below and stated the following, “the y-intercept is 4 because (4,0) has a y value of 0”. Is the student correct? Why or why not?
Answers
Answer:
No
Why he is not correct is because the y-intercept is the coordinate of the point where the graph meets or crosses the y-axis, which is equivalent to a point on the graph where the x-coordinate value reduces to zero, or to put it in a mathematical form x = 0
Step-by-step explanation:
From the given data, we have;
x [tex]{}[/tex] y
2 [tex]{}[/tex] -2
4 [tex]{}[/tex] 0
6 [tex]{}[/tex] 2
8 [tex]{}[/tex] 6
The given data is linear because it has a constant first (common) difference of 2
The general form of the straight line equation is y = m·x + c
Where;
m = The slope
c = The y-intercept
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The slope of the graph of the data from any two points, (x₁, y₁) = (4, 0) and (x₂, y₂) = (4, 0)) is m = (2 - 0)/(6 - 4) = 1
The equation representing the data in point and slope form is therefore;
y - 4 = 1 × (x - 0)
Which gives;
y = x + 4
Therefore, the y-intercept = 4.

========================================
Explanation:
The ratio QR : RS : ST is equal to 1 : 4 : 5
This means we have the following three equations
QR = x RS = 4x ST = 5xFor some positive number x.
Note the ratio QR : RS : ST turns into x : 4x : 5x, which reduces to 1 : 4 : 5 when we divide all three parts by x .
Along with those three equations, we'll also use QT = 40 as well.
Now turn to the segment addition postulate. Plug in the equations mentioned earlier, and solve for x .
QT = QR + RS + ST
40 = x+4x+5x
40 = 10x
10x = 40
x = 40/10
x = 4
So we know that
QR = x = 4
RS = 4x = 4*4 = 16
ST = 5x = 5*4 = 20
-----------
As a check,
QR + RS + ST = 4 + 16 + 20 = 40
which is the same as QT = 40
Therefore, we've confirmed that QR + RS + ST = QT is correct and we've confirmed our answers.

ato. If angle AOC + angle BOE = 70 and angle DOB
=40°, find angle BOE and reflex angle EOC.
Answers
Answer:
reflex angle EOC = 250°
Step-by-step explanation:
reflex angle EOC
= angle COA + angle DOA + angle DOB + angle BOE
angle DOB = 40° (given)
angle DOB + angle DOA = 180° (linear pair)
angle DOA = 180° - 40°
angle DOA = 140°
angle COA + angle DOA = 180° (linear pair)
angle COA = 180° - 140°
angle COA = 40°
angle COA + angle BOE = 70° (given)
angle BOE = 70° - 40°
angle BOE = 30°
Now,
we have,
reflex angle EOC = 40° + 140° + 40° + 30°
= 250°

There were 12 girls on the basketball team. 3 of them scored over 10 points in the game. What fraction represents the number of the girls on the team that scored over 10 points in the game? Explain how you got your answer.
Answers
Answer:
1/4
Step-by-step explanation:
The total number of girls on the team is 12
3 scored over 10 points
The fraction scoring over 10 points will be 3/12 = 1/4
The answer was obtained by dividing the number of girls who scored over 10 points by the total number of girls on the team
We then proceeded to write our answer in a fraction form
Answer:
1/4.
Step-by-step explanation
Since 3 of them scored over 10 points in the game, and there were 12 girls. You have to divide 12 by 3, which equals 1/4.

Step-by-step explanation:
Step 1. Calculate the rate.
rate = distance/time
r = d/t = 6 mi/4 h
===============
Step 2. Calculate the time.
r = d/t Multiply both sides by t
d = tr
t = 6 h Calculate the distance
d = 6 × 6/4
d = 36/4
d = 9 mi

The fastest pizza box folder can assemble 7 pizzas in 25 seconds. At this rate, how long would it take to assemble 21 pizza boxes
Answers
Answer:
50 seconds in order to assemble 20 pizza boxes
Step-by-step explanation:
there are two ways to solve this the first way is divide 20 by 2 which is 10 and then multiply 10 by 5 the reason to this is because we know that for every 2 it takes 5 seconds.
the second way takes longer but you write:
2, 2, 2, 2, 2, 2, 2, 2, 2, 2,
5, 5, 5, 5, 5, 5, 5, 5, 5, 5,
so here were basically writing the number 2 10 times because when u count that u can see that it equals 20 and then since for every 2 boxes it takes 5 seconds u put the 5 under each 2 so then you would count the 5s, like 5, 10 15, 20... and so on and u will see that its 50 which means 50 seconds.

Monique sells nut mixes . She uses * 1/4 of her supply of almonds to make a nut mix and of her 5/8 supply to make a fruit and nut mix. If Monique uses 28 pounds of almonds , how many pounds of almonds did she have in her supply ?
Answers
Answer:
32 pounds of almonds
Step-by-step explanation:
Monique sells nut mixes . She uses * 1/4 of her supply of almonds to make a nut mix and of her 5/8 supply to make a fruit and nut mix.
The total fraction of almonds that Monique used both for her but mix and fruit and nut mix =
1/4 + 5/8
Lowest common denominator is 8
1 × 2 + 5 × 1/8
2 + 5/8
= 7/8
If Monique uses 28 pounds of almonds
Let the total number of almonds = x
7/8 × x = 28
7x /8 = 28
Cross Multiply
7x = 8 × 28
x = 8 × 28/7
x = 32 pounds
Therefore, Monique initially had 32 pounds of almonds in her supply.

PLEASE HELP. WORTH 25 POINTS. PICTURE BELOW
Answers
Answer:
y = 5
x = 14
Step-by-step explanation:
AOC=25
AOL=90
Therefore COL = 65
COM is a 90 degree angle since MOD is 90 degrees
COM - COL = 90 - 65 = 25
5y = 25
y=5
LOB = 90
5y + 3x + 23 = 90
5(5) + 3x +23 = 90
25 + 3x + 23 = 90
48 + 3x = 90
3x= 90 - 48
3x = 42
x= 14
Answer:
x = 14, y = 5
Step-by-step explanation:
MOB = LOC
(3x + 23) + 25 = 90
3x + 23 = 65
3x = 42
x = 14
3(14)+23 + 5y = 90°
5y = 25
y = 5
