What is the slope of the line that passes through the points (-3, -3) and
(-5, -2)? Write your answer in simplest form.
Answer:
The slope in simplest form is
[tex] - \frac{1}{2} [/tex]
Step-by-step explanation:
Remember:
[tex]slope \: = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
We just plug in and solve.
[tex]slope = \frac{ - 2 - ( - 3)}{ - 5 - ( - 3)} = \frac{ \: \: 1}{ - 2} = - \frac{1}{2} [/tex]
frodo 2 4/5 miles 7/12 of an hour how many miles can a frodo run in 1 hour
Answer:
The answer is
[tex]4 \frac{4}{5} [/tex]
Explanation:
[tex] \frac{2 \frac{4}{5} \: miles}{ \frac{7}{12 \:} of \: an \: hour} = \frac{x}{1 \: hour} \\ \\ \frac{ \frac{7}{12}x }{ \frac{7}{12} } = \frac{2 \frac{4}{5} }{ \frac{7}{12} } \\ \\ x = 4 \frac{4}{5} [/tex]
Which is a solution to the equation (10–5y) = 20?
Answer:
y = -2
Step-by-step explanation:
10 -5y = 20 { subtract 10 from both sides}
-5y = 20 - 10
-5y = 10 {Divide both sides by (-5) }
y = 10/-5
y = -2
Answer: y = -2
Step-by-step explanation:
10 - 5y = 20
Add 5y to both sides
10 = 5y + 20
Subtract 20 from both sides
-10 = 5y
Divide both sides by 5
y = -2
Given: 5x + 3 > 4x + 7.
Choose the graph of the solution set.
Answer:
The first one
Step-by-step explanation:
We simplify this inequality to x>4. This means it is moving past the four to the right with an open dot
[tex]\boxed{\boxed{\pink{\bf \leadsto Option \ A \ is \ correct . }}}[/tex]
Step-by-step explanation:For the number line refer to the attachment :
A linear inequality is given to us . And we need to find the correct number line. So the given linear inequality is :-
[tex]\bf \implies 5x + 3 > 4x + 7 \\\\\bf\implies 5x - 4x > 7 - 3 \\\\\bf\implies \boxed{\red{\bf x > 4 }}[/tex]
This implies that the value of x is Greater than 4 . That is the inequality can have all the values more than 4. So when we see the given number lines we see that the first number line represents all values greater than 4 .
Hence the first graph of the solution set represents the given linear inequality.A set of middle school student heights are normally distributed with a mean of 150150150 centimeters and a standard deviation of 202020 centimeters. Let XXX represent the height of a randomly selected student from this set. Find P(X<115)P(X<115)P, left parenthesis, X, is less than, 115, right parenthesis.
Answer:
0.04
Step-by-step explanation:
Given that :
Mean(m) = 150
Standard deviation (s) = 20
Find P(X<115)
Obtain the Zscore :
(x - m) / s
(115 - 150) / 20
P(X<115) = - 1.75
Using the Z probability calculator :
P(Z < - 1.75) = 0.040059
P(Z < - 1.75) = 0.04

On the function machine shown below, the function rule is given as a variable expression. When the output is 99, what is the input? *
a 20
b 9
c 100
d 10
Answer: option d.
Step-by-step explanation:
We have the function:
y = f(x) = x^2 - 1
The output is 99 when y = 99, and the input is x.
Then we need to solve:
y = 99 = x^2 - 1
for x.
99 = x^2 - 1
99 + 1 =x^2
100 = x^2
√100 = x
10 = x
The correct option is d, input equals 10.

a.) Is the following mapping an example of a Function or Relation?
b.) Identify the domain of the mapping use a comma to separate your answers. No brackets are needed.
Answers:
a) Function
b) Domain = {3, -4, -3}
You won't type in the curly braces for the domain, but it's common to use them to indicate we're talking about a set.
========================================
Explanation:
We have a function because each item in the domain (blue oval) goes to exactly one item in the range (green oval). We don't have two arrows or more originating from one item in the domain. So each input leads to exactly one output.
The domain is the set of allowed inputs. So the domain is the set {3, -4, -3}. Those items are found in the blue oval. As your teacher instructs, you won't be typing in the curly braces, but it's common to see the domain listed as a set like this. Optionally you can sort the items from smallest to largest, but it's not necessary. This is because order doesn't matter in a set.
Answer:
a.) Function
b.) 3, -4, -3

PLS HELP !!! ace worked 22 out of his first 25 math activities correctly at the same rate, how many will he work correctly out of 100
Answer:
Ace will work 88 problems correctly out of 100.
Step-by-step explanation:
Given that:
Ace worked out 22 problems out of his 25 activities
Ratio = 22:25
If the number of problems are 100, then x be the number of problems correctly solved by Ace.
Ratio = x : 100
The relationship is proportional.
22:25 :: x:100
Product of mean = Product of extreme
25x = 22*100
25x = 2200
[tex]\frac{25x}{25}=\frac{2200}{25}\\x=88[/tex]
Hence,
Ace will work 88 problems correctly out of 100.

6 5/8 was the closing price of the bond. $6625 was the dollar amount. Therefore, the correct option is option B.
What is closing price?The final transaction price of a securities before the market formally shuts for regular trading is known as the closing price or cash value. Investors typically use closing prices as a benchmark for evaluating a stock's performance over the previous day, and they are widely used to create line graphs that show historical price fluctuations over time.
The stock price that after market closes may be impacted by dividends or stock splits; these are taken into account in the adjusted closing price. While in much lower quantities, the majority of stocks as well as other investment vehicles are traded after business hours. 6 5/8 was the closing price of the bond. $6625 was the dollar amount.
