New eq: 11x + 1. The line will become steeper.
Step-by-step explanation:
Slope is rise over run. In the original equation, y increased 4 times everytime x increased by one. In the new equation, y increased 11 times everytime x increased by one making it steeper.
How many permutations of the 26 letters of the English alphabet do not contain any of the strings fish, rat, or bird
The number of permutations of the 26 letters of the English alphabet that do not contain any of the strings fish, rat, or bird is 402619359782336797900800000
Let
[tex]\mathcal{E}=\{\text{All lowercase letters of the English Alphabet}\}\\\\B=\overline{\{b,i,r,d\}} \cup \{bird\}\\\\F=\overline{\{f,i,s,h\}} \cup \{fish\}\\\\R=\overline{\{r,a,t\}} \cup \{rat\}\\\\FR=\overline{\{f,i,s,h,r,a,t\}} \cup \{fish,rat\}[/tex]

Note that since
[tex]F \cap R=\varnothing[/tex], [tex]Perm(F)\cap Perm(R)\ne \varnothing[/tex]
But since
[tex]B \cap R \ne \varnothing[/tex], [tex]Perm(B)\cap Perm(R)= \varnothing[/tex]
and
[tex]B \cap F \ne \varnothing[/tex] , [tex]Perm(B)\cap Perm(F)= \varnothing[/tex]
Since

Maggie needs $180 to pay for a cheer camp. She has $30 already and saves $30 a week that she earns by helping her neighbors.
Use the Segment tool to plot a graph representing the amount of money Maggie has saved from the time she begins saving until she has saved enough for cheer camp.
We want to graph the linear function that models how much Maggie saves, the graph can be seen below.
So we know that maggie starts with $30, and she saves another $30 per week, then after x weeks, the total amount that she has saved is:
S(x) = $30 + $30*x
Now we have the function, to graph it, we just need to get two points of the function and then connect them with a line, to get these points, we just evaluate the function in two different values of x:
S(0) = $30 + $30*0 = $30
S(1) = $30 + $30*1 = $60
So we have the points (0, $30), (1, $60).
Now we just need to graph these points and connect them with a line, the graph can be seen below.

Suppose y varies jointly as x and z. What is y when x = 2 and z = 3, if y = 20 when x = 4 and z = 3?
Answer:
y = 10
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 20 when x = 4 and z = 3 , then
20 = k × 4 × 3 = 12k ( divide both sides by 12 )
[tex]\frac{20}{12}[/tex] = k , that is
k = [tex]\frac{5}{3}[/tex]
y = [tex]\frac{5}{3}[/tex] xz ← equation of variation
When x = 2 and z = 3 , then
y = [tex]\frac{5}{3}[/tex] × 2 × 3 = 5 × 2 = 10

The answer is 10 but Brian said the expression is equal to 83. He is incorrect because 8 times 1 is 8 and then plus 2 is 10.

Gemma is solving a division problem. After writing the problem down, she moves the decimal point directly up to the quotient. Which of these is true of Gemma’s divisor?
A
It is 0.
B
It is negative.
C
It is a decimal.
D
It is a whole number.
C? im pretty sure its c
hope this helps!
C. It is a decimal, it is true of Gemma’s divisor.
The correct answer is: C. It is a decimal.
When Gemma moves the decimal point directly up to the quotient, she is essentially performing long division by powers of 10.
This is because when you divide a number by a power of 10, you are essentially shifting its decimal point to the left by the number of positions determined by the power of 10.
For example, if she is dividing by 100 [tex](10^2)[/tex], she is moving the decimal point two places to the left.
If she is dividing by 1000 [tex](10^3)[/tex], she is moving the decimal point three places to the left, and so on.
Moving the decimal point up to the quotient means that the divisor is a decimal number, and its value determines how many decimal places Gemma needs to move the decimal point in the dividend to get the quotient.
So, the correct answer is C. It is a decimal.

Answer:
9.2
Step-by-step explanation:
We can use the Pythagorean Theorem, a^2 + b^2 = c^2 to solve this. Since a and b are the lengths of the two sides and c is the length of the hypotenuse, we modify the original formula to c = [tex]\sqrt{a^{2} +b^{2} }[/tex] to find the length of the diagonal. We would get c = [tex]\sqrt{7^{2} +6^{2} }[/tex] = 9.2.

Answer choices:
−y ≥ x + 4
−3x + 3y ≤ −9
−y ≤ 3x + 4
−3x + 3y ≤ −9
y ≤ −x − 4
−x − y ≤ − 4
y ≤ −x + 4
−4x + 4y ≤ 16
Step-by-step explanation:
the second option.
you see that the steeper line has a slope of -3 (when x increases by 1 grid point, y decreases by 3 grid points, that makes the slope ratio of y/x = -3/1 = -3).
the slope is always the factor of x in an equation of
y = ax + b
the only equation provided in the answer options with slope -3 is
-y <= 3x + 4
because when we transform this into the general firm above, we need to multiply both sides by -1 (which flips the inequality symbol, by the way) :
y >= -3x - 4
there you have it. no other equation here can be transformed into this.
as a control we also look at the second equation :
-3x + 3y <= -9
3y <= 3x - 9
y <= x - 3
this has a slope of 1 (so, x and y both increase by the same amount), and the y-inteecept is -3 (the y value when x = 0). that also fits the graph.
so, it is all correct.

Jordan’s family exchanged 250 dollars for 5000 pesos.
Jordan bought a sweater for 550 pesos.
How much dollars is it for the cost of one peso
The number of dollars for one peso is 20 dollars.
Exchange rate is the rate at which one currency is exchanged for another currency.
In order to determine how many pesos can be exchanged for a dollar, the value of pesos would be divided by the amount of dollars exchanged.
Exchange rate = 5000 / 250 = 20 dollars
This means that 1 peso would be exchanged for 20 dollars.
