Find the equation of the line that passes through (1,-1) and is parallel to 2x+y−3=0.
Leave your answer in the form y=mx+c
Answer: y= -2x + 1
Step-by-step explanation:
We can formulate the slope equation of that line by
S= Y-Y1/X-X1
By the given statement "parallel", the slope of the function "y=3-2x" shall then equals the first line -->1
to conclude, we will use the first point at x=1 ( Like the given point of the line) and additional point at x=0...
y(1)=3-2(1)=1, Hence, (1,1)
y(0)=3-2(0)=3, Hence, (0,3)
By the fact 1
then we shall conclude with simple linear equation as follow
m=y2-y1/x2-x1 = 1-3/1-0=-2
The general formula of the Required function is y=mx+c
In fact the line passes through the point (1,-1)
Hence y in x=1 equals -1
-1= -2(1)+C
C= -1+2=1
Then FINALLY the line formula isy= -2x + 1Expert Answer Please !Decide If SSS,ASA,AAS,SAS,HL, or None

Step-by-step explanation:
Write an equation of a line that has a slope of -2 and passes through the point (1,4)
Answer:
y = -2x + 6
Step-by-step explanation:
Since we already have the slope we just need to find the y-intercept.
To do that just plug in the point you were given. (1,4)
4 = -2(1) + b (b represents the y-intercept)
4 = -2 + b (add 2 on both sides)
6 = b
y = -2x + 6 is the equation
Hope this helps!!
Answer:
The equation (in y=mx+b form) would be y= -2x+6
Step-by-step explanation:
The slope is given from the start, which is -2, so you would plug that in for m to make the equation y=-2x but this IS NOT YOUR ANSWER
I was able to graph it, although there are multiple ways to do this.
Next you have to find the y-intercept. You use your coordinate (1,4) and go up twice (positive) (1,6) and go to the left (negative) to get the point (0,6) giving you your intercept.
Plugging it into the equation for b, your equation would now be y= -2x + 6 giving you your final answer
Parallel lines e and f are cut by transversal b. What is the value of y?
16
50
130
164
Answer:
y = 130
Step-by-step explanation:
Those two exterior angles are equal (property of parallel lines)
y is thsupplement of 4x - 14
2x + 18 = 4x - 14 Add 14 to both sides
2x + 18 + 14 = 4x - 14 + 14 Combine like terms
2x + 32 = 4x Subtract 2x from both sides
2x-2x+32=42-2x Combine
32 = 2x Divide by 2
32/2 = x
16 = x
============
4x - 14 =64 - 14 = 50
y = 180 - 50
y = 130

The figure below is made up of a square with height, h, units and a right triangle with height, h units, and a base length, b units.
The area of this figure is 80 square units.
Write an equation for the area of the shape below.
Answer:
Step-by-step explanation:
A = 12 × 16 + (1/2)(12 + 8)(10) = 292 units²
The Equation for Area of figure is area of Figure, h² + 1/2(h)(b) = 80
What is Area?The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given:
We have the figure consist of one rectangle and one right triangle.
Now, Area of Figure,
=Area of rectangle + area of Triangle
= length x width + / x base x height
= 16 x 12 + 1/2 x 10 x 20
= 192+ 100
=292 unit²
and, if the square with height, h, units and a right triangle with height, h units, and a base length, b units.
Then, area of Figure= h² + 1/2(h)(b) = 80 square units.

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
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
Coordinates of vertex are (- 3, 5)
(b). The axis of symmetry is x = - 3
(c). The given function opens downward
y = 5 is a maximum of a given function.
the diagram shows a circle inside a square ABCDB AB = 20 cm. the radius of the circle is 9 cm. work out the area of the shaded region
Step-by-step explanation:
Area of the square = a²
= 20²
= 400cm²
Area of the circle = πr²
= 22/7 × 9²
= 22/7 × 81
= 254.57cm²
Area of the shaded region = Area of the square - Area of the circle
= 400cm² - 254.57cm²

A: both negative
B: both positive
C: one negative and one positive
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

OkThe 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
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.

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
