Find the equation of the line. Use exact numbers.
Answer:
[see below]
Step-by-step explanation:
Using two points on the line:
(0,3) (2,0)
Find the slope of the line:
[tex]m=\frac{rise}{run}=\frac{0-3}{2-0}=\frac{-3}{2}=-\frac{3}{2}[/tex]
The slope of the line is [tex]-\frac{3}{2}[/tex].
The y-intercept is (0,3).
The line equation should be: [tex]y=-\frac{3}{2}x+3[/tex].
Hope this helps.
Answer:
[tex]y=-\frac{3}{2}x+3[/tex]
Step-by-step explanation:
We can find an equation for the line by using the slope of the line and the y-intercept.
We can see that the y-intercept of of the line is 3.
To find the slope of the line, we can use the slope formula. The slope formula is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where (x₁, y₁) and (x₂, y₂) are points on the line. To find the slope of the line, I will use the x-intercept, which is (2, 0), for (x₂, y₂) and y-intercept, which is (0, 3), for (x₁, y₁).
[tex]m=\frac{0-3}{2-0}=\frac{-3}{2}=-\frac{3}{2}[/tex]
So now we know the y-intercept and the slope, so lets plug it into the slope-intercept form equation. This gives us:
[tex]y=-\frac{3}{2}x+3[/tex]
So the equation of the line would be [tex]y=-\frac{3}{2}x+3[/tex].
I hope you find my answer helpful.

Alexis bakes 90 identical pizzas. Each pizza is cut either into 8 small slices or 6 large slices. There are 5 small slices for for every 3 large slices. How many of the 90 pizzas are cut into small slices?
Answer:
50
Step-by-step explanation:
Let x represent the number of pizzas cut into small slices. Then the ratio of small to large slices is ...
[tex]\dfrac{8x}{6(90-x)}=\dfrac{5}{3}\\\\8x=10(90-x)\quad\text{multiply by $6(90-x)$}\\\\18x=900\quad\text{add $10x$}\\\\x=50\quad\text{divide by 18}[/tex]
50 of the 90 pizzas were cut into small slices.
_____
Check
The 50 pizzas cut into 8 small slices each results in 400 small slices. The 40 pizzas cut into 6 large slices each results in 240 large slices. The ratio of small slices to large slices is 400 : 240 = 5 : 3.

Answer:
C) 6
Step-by-step explanation:
I converted the equation into slope-intercept form and then identified the y-intercept.
[tex]4x+2y=12\\\\4x-4x+2y=12-4x\\\\2y=12-4x\\\\\frac{2y=12-4x}{2}\\\\ y=6-2x\\\\y=-2x+6\\\\y=-2x+\boxed{6}[/tex]
C should be the correct answer.
Hope this helps.
Answer: 6
Step-by-step explanation: The y-intercept is a point where a line
crosses the y-axis and all y-intercepts have an x-coordinate of zero.
So to find the y-intercept of this line, we can plug a 0 in for x.
So we have 4(0) + 2y = 12.
So 2y = 12 which means that y = 6.
So the y-intercept of this line is 6.

Given the function f(x) = 3 (x - 9) + 6 which of the following represents f-1 (x)?
Answer:
[tex]f^{-1}[/tex](x) = [tex]\frac{1}{3}[/tex] x + 7
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 3(x - 9) + 6 ← distribute and simplify right side
y = 3x - 27 + 6 = 3x - 21 ( add 21 to both sides )
y + 21 = 3x ( divide all terms by 3 )
[tex]\frac{1}{3}[/tex] y + 7 = x
Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus
[tex]f^{-1}[/tex](x) = [tex]\frac{1}{3}[/tex] x + 7
If a leaf fell 140 meters in 4 minutes how many meters did it travel per minute?
Answer:
The leaf travels 35 meters per minute
Step-by-step explanation:
Given:
Distance = 140 meters
Time = 4 minutes
Speed = distance / time
Speed in meter per minute
Distance in meter
Time in minutes
Speed = distance / time
= 140 meters / 4 minutes
= 35 meters per minutes
Therefore,
The leaf travels 35 meters per minute

Explain how you get the answer to 7|8-3h|=21h-49
Awnser-H=5/2
Explantion- Absolute value equalitiy entered
7|-3h+8| = 21h-49 Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is 7|-3h+8|
For the Negative case we'll use -7(-3h+8)
For the Positive case we'll use 7(-3h+8)
-7(-3h+8) = 21h-49
Multiply
21h-56 = 21h-49
Rearrange and Add up
0h = 7
False, No solution for the Negative Case 7(-3h+8) = 21h-49
Multiply
-21h+56 = 21h-49
Rearrange and Add up
-42h = -105
Divide both sides by 42
-h = -(5/2)
Multiply both sides by (-1)
h = (5/2)
Which is the solution for the Positive Case When an absolute value equation has just one solution, that solution has to be checked:
The equality is 7|-3h+8| = 21h-49
The solution is h = 5/2
We check the solution by plugging it for h
7|-3(5/2)+8| = 21(5/2)-49
The left hand side is equal to (7/2)
The right hand side is equal to (7/2)
The two sides are equal!
Solution checks!

How to put 634 in scientific form
Answer:
6.34 × 10²
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 634
New Number: 6.34
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 6 . 3 4
Decimal Count: 1 2
There are 2 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 6.34
b = 2
Now the whole thing:
6.34 x 10²
Step 4
Check your work:
10² = 100 x 6.34 = 634
Answer:
6.34 x 10^2

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be A
11x - 7y = -4 be equation (1)
Let the second equation be B
-14x - 2y = -4 be equation (2)
On simplifying , we get
Multiply equation (2) by 7 , we get
-98x - 14y = -28 be equation (3)
Multiply equation (1) by 2 , we get
22x - 14y = -8 be equation (4)
Subtract equation (4) from equation (3) , we get
-120x = -20
Divide by 120 on both sides , we get
x = 1/6
Now , substituting the value of x in equation (1) , we get
11x - 7y = -4
11 ( 1/6 ) - 7y = -4
Adding 7y on both sides , we get
7y - 4 = 11/6
Adding 4 on both sides , we get
7y = 11/6 + 4
7y = 35/6
Multiply by 7 on both sides , we get
y = 5/6
Hence , the value of x is 1/6 and value of y is 5/6

x=___
y=___
Answer:
X = 9 and Y = 8
Step-by-step explanation:
We are to find the midpoint of the coordinates (13,15) and (5,1).
Using the midpoint formula;
M(X, Y) = [(x1+x2)/2, (y1+y2)/2]
X = (x1+x2)/2
Y = (y1+y2)/2
From the coordinates, x1 = 13, y1 = 15, x2 = 5 and y2 = 1
X = 13+5/2
X = 18/2
X = 9
Similarly;
Y = 15+1/2
Y = 16/2
Y = 8
Hence The Tourist Information Center is located at point X = 9 and Y = 8
Ori needed at least $1.47 in postage to mail an envelope to his cousin overseas. If x represents the number of $0.44 cent stamps he has and y represents the number of $0.10 cent stamps he has, the inequality representing the number of stamps he can use to mail the envelope is 0.44x+0.10y≥1.47. If Ori uses all 3 of the $0.44 cent stamps he has, what is the minimum number of $0.10 stamps he needs to use?
The minimum number of $0.10 stamps he needs to use is 1 stamp.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
let x represents the number of $0.44 cent stamps
and, y represents the number of $0.10 cent stamps
Ori uses all 3 of the $0.44 cent
=0.44x3
= 1.32
Then, 1.47-1.32= 0.15
We have at least 2 dimes for the equation
=0.44(3)+0.10(2)≥1.47
= 1.32+0.20≥1.47
= 1.52≥1.47
Then, number of $0.10 stamps he needs to use
= 0.15/ 0.10
= 1.5
= 2 or 1 stamps
