Noelle is 4 feet tall and her brother Oliver us 42 in. How many inches taller is Noelle than Oliver?
Answers
Answer:
6 inches
Step-by-step explanation:
There are 12 inches in 1 foot so
12 inches X 4 feet = 48 inches
Then we subtract the 48 in minutes the 42 in to find the difference between Noelle and Oliver's height
48-42=6

Solve the equation.
y + 3 = -y + 9
O y = 1
O y = 3
O y = 6
O y = 9
Answers
Answer:
y = 3
Step-by-step explanation:
Subtract 3 from both sides of the equation
y + 3-3 = -y + 9-3
Simplify
y = -y + 6
Add y to both sides of the equation
y+y=-y+6+y
Simplify
2y = 6
Divide both sides of the equation by the same term
2y/2 = 6/2
Simplify
y = 3
[RevyBreeze]
The solution of the Equation is y= 3.
We have, the equation is
y + 3 = -y + 9
y + y = 9 - 3
2y = 6
Now, divide both side we get
2y = 6
2y/ 2 = 6/ 2
y = 3
Thus, the solution of y is 3.

How do I turn (7, -1) and (21, -5) into slope intercept form
Answers
I think the easiest way to do this is through point slope form, but first you’ll need to find your slope.
To make it easier first you want to label your points x1, y1, x2, y2
7 is x1
-1 is y1
21 is x2
-5 is y2
the formula to find the slope is
y2-y1
m= ———
x2-x1
then you’re going to plug in all the numbers
it should look like this
-5 + 1
m= ———
21-7
hint: two negative makes a positive that’s how it ended up being plus 1
then do you math.
you should end up with -4/14
which simplifies to -2/7
NOW you need to find the “b” by doing point slope
formula: y-y1 = m(x - x1)
you’re only plugging things in for y1, m, and x1.
so you’re equations should look like this
y + 1 = -2/7(x - 7)
REMEMBER( two negatives make a positive.. that’s why it’s + 1 and not -1)
Distribute -2/7
y+1 = -2/7x + 2
Subtract 1 from 2
y = -2/7x + 1
Andd done.

Part: 0/6
Part 1 of 6
Let P.be the statement: 3+5+7+ ... + (2n+1)=n(n+2).

Answers
When proving by induction, your first step is to show that a given claim is true for some minimal case (often called the base case). The given statement is a claim about the sum of numbers of the form 2n + 1 where n is a positive natural number. The least positive natural number is n = 1, so that seems like a reasonable place to start.
Now, we show the claim holds for n = 1:
3 + 5 + 7 + … + (2n + 1) = n (n + 2)
is a statement about an arbitrary positive integer n; the case of n = 1 reduces to
3 = 1 (1 + 2) = 1 • 3 = 3
which is obviously true.
Next, we assume that the statement is true for some arbitrary positive integer n = k, so that
3 + 5 + 7 + … + (2k + 1) = k (k + 2)
This is called the induction hypothesis.
We then use this assumption to show that the claim is also true for the next positive integer, n = k + 1. This is the claim that
3 + 5 + 7 + … + (2k + 1) + (2 (k + 1) + 1) = (k + 1) (k + 1 + 2)
or
3 + 5 + 7 + … + (2k + 1) + (2k + 3) = (k + 1) (k + 3)
By the induction hypothesis, we have
3 + 5 + 7 + … + (2k + 1) + (2k + 3)
= k (k + 2) + (2k + 3)
= k² + 2k + 2k + 3
= k² + 4k + 3
= (k + 1) (k + 3)
and this is exactly what we wanted to show, that if P(k) is true, then P(k + 1) is also true.
This means we have
P(1) = true ⇒ P(2) = true ⇒ P(3) = true ⇒ …
and so on, and the claim is true for all positive integers n.
Hi there I don't usually ask questions but I'm having a bit of trouble solving for X on this equation. 1+(3x-3)=1 You don't necessarily have to give me the answer, a break down would be just fine :)
Answers
Answer:
[tex]x=1[/tex]
Step-by-step explanation:
[tex]1+(3x-3)=1[/tex]
First, you have to take the one that is outside of the Parenthesis and take it to the other side. That would mean it would be this:
[tex]3x-3=1-1[/tex]
1 - 1 is 0
[tex]3x-3=0\\[/tex]
Move the -3 to the other side, which makes it positive;
[tex]3x=3[/tex]
Divide both sides by 3
[tex]x=1[/tex]
If you want to check it, you can replace 1 in the original equation:
[tex]1+(3X1-3)=1[/tex]
[tex]1+(0)=1[/tex]
[tex]1=1[/tex]
So x=1

Which of the following describes exponential decay?
A.) The amount at a given time can be calculated by subtracting an amount from the previous amount.
B.) The amount at a given time can be calculated by adding an amount to the previous amount.
C.) The amount at a given time can be calculated by multiplying the previous amount by a value less than 1.
D.) The amount at a given time can be calculated by multiplying the previous amount by a value greater than 1.
Answers
Answer:
C. The amount at a given time can be calculated by multiplying the previous amount by a value less than 1.
Step-by-step explanation:
Exponential decay is when an exponential function decreases per x-value. These functions go by a multiplier and are therefore, not linear, so you cannot add or subtract. Because the function is decaying, it is multiplying by an amount less than 1, since the multiplier is 1 - r, where r is the percent.
