11. A line that passes through (3, 1) and (0, -3)
Answers
Answer:
y=(4/3)x - 3
Step-by-step explanation:
Use equation (y-y1) =m (x-x1)
slope is m= (y1-y2)/(x1-x2)=1+3/3-0=4/3
use one of the points and this slope to complete the equation
(y-1)=(4/3)(x-3) distribute and add1 to both sides
y=(4/3)x-(3*4/3)+1
y=(4/3)x - 3
Answer:
y = [tex]\frac{4}{3}[/tex] x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 1) and (x₂, y₂ ) = (0, - 3)
m = [tex]\frac{-3-1}{0-3}[/tex] = [tex]\frac{-4}{-3}[/tex] = [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = [tex]\frac{4}{3}[/tex] x - 3 ← equation of line

what's y intercept on a graph of y = -5x + 6
Answers
The y-intercept on a graph of y = -5x + 6 is 6.
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
We have a linear equation,
y = -5x + 6.
The general slope-intercept form,
y = mx + b.
Where m is the slope and b is the y-intercept.
Comparing,
b = 6.
Therefore, 6 is the y-intercept.

For the function below, (a) find the vertex; (b) find the axis of symmetry; (c) determine whether there is a maximum or a
minimum value and find that value; and (d) graph the function.
f(x) = -x2 - 6x-4
Answers
Answer:
Step-by-step explanation:
f(x) = ax² + bx + c
"x" coordinate of vertex is ( - [tex]\frac{b}{2a}[/tex] )
axis of symmetry is x = - [tex]\frac{b}{2a}[/tex]
If a > 0 the function opens upward and has minimum value.
If a < 0 the function opens downward and has maximum value.
f(x) = - x² - 6x - 4
(a). x = - [tex]\frac{-6}{-2}[/tex] = - 3 ; y = - (- 3)² - 6( - 3) - 4 = 5

Step-by-step explanation:
Given two points, we can find the equation of the line between them with the following:
[tex]y = mx + b\\m = \frac{y_2-y_1}{x_2-x_1}[/tex]
First, we can calculate m, or slope
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-0}{1-(-4)} = \frac{5}{5} = 1[/tex]
Next we can use the top equation and solve for b, the y-intercept

Answers
Complete question :
You have 20 quarters. You find 40% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters.
A. Write an expression that represents the total number of quarters you take with you when you go shopping.
B. How much money do you have left?
Answer:
[20 + (0.4*20)] = 28 quarters
$3.5
Step-by-step explanation:
Given that:
Initial number of quarters = 20
Quarters in room = 40%
Hence, Numbe of quarters in room = 0.4 * 20 = 8
Total number of quarters taken for shopping :
(Initial amount + Numbe of quarters in room)
(20 + 8) = 28 quarters
50% of quarters was spent on shopping :
0.5 * 28 = 14 quarters
Total left :
28 - 14 = 14
Quarters left in dollars :
1 quarter = 25 cent = 0.25 dollars
14 * $0.25 = $3.5

Answers
Answer:
A, A and A
Step-by-step explanation:
Given
y = ax² + bx + c
• If a > 0 then minimum vertex
• If a < 0 then maximum vertex
Here the vertex is a maximum, thus a < 0 , that is negative → A
The value of c is the y- intercept
The graph crosses the y- axis below the y- axis, thus c is negative → A
The solutions to ax² + bx + c = 0 are the values of x on the x- axis where the graph crosses the x- axis.
The graph crosses the x- axis to the left of the y- axis , thus
Both solutions are negative → A

The front and back covers of a textbook are each 0.3 cm thick. Between the covers are 200 sheets of paper, each 0.008 cm thick. How high is a stack of 10 books
Answers
Answer:
22 cm
Step-by-step explanation:
Start off by multiplying the number of pages by the thickness.
200*0.008=1.6
Add the thickness of the front and back cover.
1.6+0.6=2.2
Multiply by 10.
2.2*10=22 cm
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The height of the 10 stacks of books is 22cm.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the front and back covers of a textbook are each 0.3 cm thick. Also, there are 200 sheets of paper between the cover and the thickness of each sheet is 200 sheets. Therefore, the thickness of the book is,
The thickness of a single book
= (Number of covers × Thickness of cover) + (Number of sheets × Thickness of sheets)
= (2 × 0.3cm) + (200 × 0.008cm)
= 2.2 cm
Now, the thickness of 10 books will be,
The thickness of 10 books = 10 × the Thickness of a single book
= 10 × 2.2 cm
= 22 cm
Hence, the height of the 10 stacks of books is 22cm.

make y the subject of the following :
Answers
Step-by-step explanation:
we first square both sides to eliminate the square root brackets..
(√(m(y+n)/y)²= p²
m(y+n)/y = p²
(my +mn)/y =p²
so we multiply both sides by y to eliminate the denominator,
(my+mn)/y*y =p²*y
my+mn = p²y
collecting like terms,we have:
mn= p²y-my
so we seperate the y on the right hand side from the rest to have
mn = y(p²-m)
so divided both sides by the value in the bracket on the right hand side we have..
mn/(p²-m)=y(p²-m)/(p²-m)
so we have,
y= mn/(p²-m)
Answer:
y = [tex]\frac{-mn}{m-p^2}[/tex]
Step-by-step explanation:
Given
[tex]\sqrt{\frac{m(y+n)}{y} }[/tex] = p ( square both sides )
[tex]\frac{m(y+n)}{y}[/tex] = p² ( multiply both sides by y )
m(y + n) = p²y ← distribute parenthesis on left side
my + mn = p²y ( subtract p²y from both sides )
my - p²y + mn = 0 ( subtract mn from both sides )
my - p²y = - mn ← factor out y from each term on the left side
y(m - p²) = - mn ← divide both sides by (m - p²)
y = [tex]\frac{-mn}{m-p^2}[/tex]
