What is the y-intercept of the line that passes through the points (2, -1) and
(-3, 9)?
Answer:
the y intercept is (0, 3)
Step-by-step explanation:
y = mx + c
where m is the slope and c is the y-intercept
[tex]m = \frac{y_2 - y_1}{x_2 - x_1 }[/tex]
[tex]m = \frac{9 - -1}{-3 - 2 }[/tex]
[tex]m = \frac{10}{-5}[/tex]
[tex]m = -2[/tex]
hence, y = -2x + c
input a pair of values, in this case i will use (2, -1)
-1 = -2(2) + c
-1 = -4 + c
-1 + 4 = c
3 = c

10.6n - 45.92 = 18.8 solve for n
Answer:
Step-by-step explanation:
10.6n - 45.92 = 18.8 Add 45.92 to both sides
10.6n = 18.8 + 45.92 Combine like terms on the right
10.6n = 64.72 Divide by 10.6
n = 64.72 / 10.6
n = 6.11
When air is pumped into an automobile
tire, the pressure is inversely proportional to
the volume. If the pressure is 35 pounds
when the volume is 120 cubic inches, what
is the pressure when the volume is 140
cubic inches?
Answer:
The pressure P₂ = 30 pounds when volume is 140 cubic inches
Step-by-step explanation:
We are given
Pressure P₁ = 35 pounds
Volume V₁ = 120 cubic inches
Volume V₂ = 140 cubic inches
We need to find Pressure P₂
The formula used will be: [tex]V_1P_1=V_2P_2[/tex]
Putting values and finding P₂
[tex]V_1P_1=V_2P_2\\120\times 35=140\times P_2\\4200=140\times P_2\\P_2=\frac{4200}{140} \\P_2=30 \ pounds[/tex]
So, the pressure P₂ = 30 pounds when volume is 140 cubic inches

A recipe calls for 1 1/2 cups of mayonnaise and 3/8 cups of pecans. How much mayonnaise should be used if 1 cup of pecans is used?
Answer:
4 cups of mayonnaise.
Step-by-step explanation:
The ratio of the amount of pecans comparing reality and the recipe is:
1 : 3/8
= 1/(3/8)
= 8/3
Hence, to find the amount of mayonnaise that should be added:
8/3 * 3/2
= 8/2
= 4 cups

Solve the equation 3/4x + 3 -2x = -1/4+1/2x+5
If necessary: Combine Terms
Apply Properties: Add, Subtract, Multiply, Divide
Answer:
x = -1
Step-by-step explanation:
3/4x + 3 -2x = -1/4 + 1/2x + 5
3/4x + 3 -2x = 19/4 + 1/2x
3x + 12 - 8x = 19 + 2x
-5x + 12 = 19 + 2x
-5x - 2x + 12 = 19
-7x = 19 - 12
-7x = 7
x = -1

=> 0.8x = 36+8
=> 0.8x = 44
=> x = 44÷0.8
=> x = 55
x= 55.
The solution of the expression will be;
⇒ x = 55
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ -0.8 (10 - x) = 36
Now,
We can solve the expression as;
The expression is,
⇒ -0.8 (10 - x) = 36
⇒ - 0.8 × 10 + 0.8x = 36
⇒ - 8 + 0.8x = 36
⇒ 0.8x = 36 + 8

Answer:In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

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 total amount be A = 10 kg
Now , the percentage decrease in value = 10 %
So , the equation will be
The amount after decrease =
Total amount - ( percentage decrease in value x total amount )
And , the equation is
The amount after decrease = 10 - ( 10/100 ) x 10
= 10 - 0.1 x 10
= 10 - 1
The amount after decrease = 9 kg
Therefore , the value is 9 kg after decrease in 10 %
Hence , The value after the decrease in 10% is 9 kg

The solution is, the function y=10+×. is plotted below.
What is a function?A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.
here, we have,
The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.
It is a straight line because the degree of the variable or its maximum power is one.
Put x = 0
y = 10 + 0 = 10, therefore one point (0,10)
Put y = 0
0 = 10 +x
Another point since x = -10. (-10,0)
As shown in the graph below, a straight line should be drawn through both locations.
Any point on the line that does not satisfy the equation is a nonexistent point.
Hence the function y=10+×. is plotted below.

Douglas has a box with 49 paper clips.
Of the paper clips, 15 are yellow, 9 are
red, 6 are blue, 11 are orange and 8
are green. Douglas randomly picks 2
paper clips from the box.
If the first paper clip is red, what is the probability that the second paper clip is blue?
Answer:
6/48 is the likely possibility that he will pull out a blue one.
Step-by-step explanation:
The first thing you will look at is how many blue there is and in this case there is 6. All you have to do (if it didn't already) is add up all of the paperclips and put the blue total number to get your answer. So if there was 49 but he drew out one to make it 48. So the answer is 6/48

The formula A = Pe^rt calculates the amount an investment earning a nominal rate of r compounded continuously is worth. Show that the amount of time it takes for the investment to double in value is given by the expression ln2/r.
Answer:
t = In2/ r
Step-by-step explanation:
Given the formula : A = Pe^rt
For investment to double ;
Final amount (A) = 2 * initial investment (p)
A = 2p
Hence,
2p = pe^rt
2 = e^rt
Take the In of both sides
In2 = rt
Divide both sides by r
In2 /r = rt /r
In2/ r = t
t = In2/ r ; Hence, the proof
The formula for obtaining the time taken when the amount is double the principal is ln2/r.
Given that;
A = Pe^rt
A = amount
P = principal
r = rate
t = time
Now we are told that;
A = 2P
Hence;
2P = Pe^rt
2 = e^rt
ln 2 = rt
t = ln2/r (QED)

Laura's ingredient was used the least. More of Paige's ingredient was used than Jacob's. Who brought the ginger?
1/4 cinnamon was left, so 3/4 was used.
1/3 nutmeg was left, so 2/3 was used
1/2 of ginger was left so 1/2 was left
5/8 of pumpkin was left so 3/8 was used.
Corey's was used the most, 3/4 is the largest used, so Corey had the cinnamon.
Laura's was used least, 3/8 is the smallest amount so Laura had the pumpkin.
2/3 is more then 1/2, so there was more ginger used than nutmeg.
More of Paige's was used, so Paige had the ginger.
