Given:
A line passes through the points (1,-7) and (5,-25).
To find:
The y-intercept of the line.
Solution:
The line passes through the points (1-7) and (5-25). So, the equation of the line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-7)=\dfrac{-25-(-7)}{5-1}(x-1)[/tex]
[tex]y+7=\dfrac{-25+7}{4}(x-1)[/tex]
[tex]y+7=\dfrac{-18}{4}(x-1)[/tex]
[tex]y+7=-4.5(x-1)[/tex]
Subtracting 7 from both sides, we get
[tex]y=-4.5x+4.5-7[/tex]
[tex]y=-4.5x-2.5[/tex]
Putting x=0, we get
[tex]y=-4.5(0)-2.5[/tex]
[tex]y=0-2.5[/tex]
[tex]y=-2.5[/tex]
Therefore, the y-intercept of the given line is -2.5 and the vertex form of (0,-2.5).

Step-by-step explanation:
Ciara has a bag of 60 colored marbles. There are purple, green, and red marbles,. She empties the bag, sorts the marbles, and counts 11 purple marbles and 20 green marbles. She wants to write a ratio of the number of purple marbles to the number of red marbles. How can she find the number of red marbles without counting them?
Answer:
[tex]Red = 29[/tex]
Step-by-step explanation:
Given
[tex]Total = 60[/tex]
[tex]Purple = 11[/tex]
[tex]Green = 20[/tex]
Required
Number of red marbles, without counting
To do this, we simply subtract the sum of the purple and red marbled from the total marbles.
So, we have:
[tex]Red = Total - (Purple + Green)[/tex]
[tex]Red = 60 - (11 + 20)[/tex]
[tex]Red = 60 - 31[/tex]
[tex]Red = 29[/tex]

Molly and George earned 352 points together. Molly has half the number of points as
George. Which equation could represent this situation? Let g represent the number of
points George earned.
Answer:
Assume G = George
I can use the problem to find that:
G + 1/2G = 352

Answer:
<B = 56.25°
Step-by-step explanation:
Reference angle = B
Hypotenuse = AB = 9
Adjacent = BC = 5
Applying trigonometric ratio:
[tex] cos (B) = \frac{adj}{hyp} [/tex]
[tex] cos (B) = \frac{5}{9} [/tex]
[tex] B = cos^{-1}(\frac{5}{9}) [/tex]
B = 56.25° (nearest hundredth)

In rhombus QRST diagonals RT and QS are drawn. If m
then which of the following is the measure of
a 76
b 90
C 38
d 48
HELP ME PLEASE !!! thank you
Answer:
<STR = 38degrees
Step-by-step explanation:
Find the diagram attached
Complete Question:
In Rhombus QRST, diagonals RT and QS are drawn. If m<TSR = 104°, then which of the following is the measure of <SRT?
Sicne triangle STR is isosceles, hence the base angles are equal. Let the base angles be y
y+y+104 = 180
2y = 180-104
2y = 76
y = 38degrees
Since <STR = y, hence the measure of <STR = 38degrees
which alphabet is missing Y E W G U I
Answer:

The missing alphabet between Y and W= X
The missing alphabet between W and U= V
The missing alphabet between E and G=F
The missing alphabet between G and I=H
What is alphabet?
An alphabet is a standardized set of basic written symbols or graphemes that represent the phonemes of certain spoken languages.
According to question, we have to find which alphabet is missing Y E W G U I.
If we find missing alphabet between bold alphabet Y E W G U I,
we get the following
The missing alphabet between Y and W= X
The missing alphabet between W and U= V
If we find missing alphabet between bold alphabet Y E W G U I,
we get the following
The missing alphabet between E and G=F
The missing alphabet between G and I=H
Hence , we can conclude that
The missing alphabet between Y and W= X
The missing alphabet between W and U= V
The missing alphabet between E and G=F
The missing alphabet between G and I=H

Rearrange the equation so q is the independent variable 9q - 4 = 3r - 6
3r = 9q - 4 + 6
r = (9q + 2)/3
Answer: r = (9q + 2)/3
Answer:
q = [tex]\frac{3}{9}[/tex]r -[tex]\frac{2}{9}[/tex]
Step-by-step explanation:
9q - 4 = 3r - 6
+4 on both sides
9q = 3r - 2
Divide both sides by 9
q = [tex]\frac{3}{9}[/tex]r -[tex]\frac{2}{9}[/tex]

The salaries of 4 players on a professional basketball
team average $200,000 per year. If a fifth player is hired
for $400,000 per year, what will be the average salary
for the 5 players?
If salary average of 4 players is making $200,000/yr, what's the total payroll? It should be $200K x 4 or $800,000.
Now if you add in that 5th player at $400,000 what is the total payroll of all 5 players? It should be $800,000 + $400,000 = 1,200,000. From there you can find the average of the 5 players by dividing!

(2+___i) + (___+3i) = 6 + 8i
Answer:
(2+ 5i) + (4 + 3i) = 6 + 8i
Step-by-step explanation:
2 + xi + y + 3i = 6 + 8i
(2 + y) + xi + 3i = 6 +8i
(2 + y) + (x + 3)i = 6 + 8i
Compare real numbers
2 + y = 6
y = 6 - 2
y = 4
Compare imaginary numbers
x + 3 = 8
x = 8 - 3
x = 5
