hope u understand
Step-by-step explanation:
Unit rates can conveniently be multiplied by any desired number in order to answer questions about differently scaled questions. E.g. If three marbles cost 30 cents, how much will eleven marbles cost?
A unit rate is a ratio such as 30 cents : 3 marbles = 10 cents per (1) marble, after doing the division.
Answer:
ratios, rates, and unit rates can be used to solve how much of something there is compared to another thing. Ex: There are 3 times the amount of apples compared to oranges. How many apples are there if you have 2 oranges? For a ratio, you would make it 3:1. Then substitute the 1 for 2. For a rate, you would make it 3 apples per oranges. Then do the same thing you would do for the ratio. Unit rates work the same way.

What is the vertex for the graph shown below?
a. (0,0)
b. v=1
c. v=5
d. (5,1)
Answer:
D. (5,1)
Step-by-step explanation:
The vertex of the graph is V ( 5 , 1 ).
Given data:
The vertex of a function is a point on the graph where the function reaches its highest or lowest point, depending on whether the function is concave up or concave down.
The vertex represents the minimum or maximum point of the function and provides information about the axis of symmetry of the graph. If the function opens upward (concave up), the vertex is the lowest point (minimum).
So, the highest point in the graph where the function reaches the minimum value is when x = 5
So, the value of y = 1
Hence , the vertex is V ( 5 , 1 ).

If f(x)=|x+7|, find f(−12).
−19
−5
5
19
Answer:
5
Step-by-step explanation:
insert f(-12) for f(x) and solve
f(-12)=|-12+7|
add -12 and 7
f(-12)=|-5|
absolute value makes it positive
f(-12)=5
If f(x)=|x+7|, the value of f(-12)=5
Given :
the function f(x)=|x+7|. Lets find out f(-12)
f(x) is an absolute function . Absolute function always gives us positive value .
for example |-6|=6
In f(-12) the value of x is -12
To find f(-12) we replace x with -12 in f(x).
[tex]f(x)=|x+7|\\f(-12)=|-12+7|\\f(-12)=|-5|\\f(-12)=5[/tex]
so, we got f(-12)=5
The answer is 5

Find the next three terms:
5, 8, 11, 14...
Answer:
next 3 terms are 17,20,23
Step-by-step explanation:
to get from 5 to 8 you add 3
14+3=17
17+3=20
20+3=23
Answer:
17, 20, 23
Step-by-step explanation:
The pattern is that 3 is added every time.
5 + 3 = 8, 8 + 3 = 11, 11 + 3 = 14.
That means that the next terms will be
14 + 3 = 17
17 + 3 = 20
20 + 3 = 23
Please help I really need it!! A student found out that 8% of the students in his school are left-handed.If there are 114 lefties, how many students are in his school?
Answer:
x = 1425
Step-by-step explanation:
Given that,
A student found out that 8% of the students in his school are left-handed.
Total no of lefties = 114
We need to find the total number of students in the school. Let they are be x.
ATQ,
8% of x = 114
[tex]\dfrac{8x}{100}=114\\\\x=\dfrac{114\times 100}{8}\\\\=1425[/tex]

There is 1/2 of a greater chance in drawing a spade over drawing a 7
How to determine the probability?From the complete question added as an attachment, we have the following parameters:
n(Spade) = 4n(7) = 1Total = 6The probability of getting a spade is:
P(Spade) = 4/6
The probability of getting a 7 is:
P(7) = 1/6
The difference between both probabilities is:
Difference = 4/6 - 1/6
Evaluate
Difference = 3/6
Simplify
Difference = 1/2
Hence, there is 1/2 of a greater chance in drawing a spade over drawing a 7

Determine whether or not the equation shows a proportional relationship. If it does, identify the unit rate (constant of proportionality).
y =25x, a = 5x + 5, m = 105.25n
Answer:
y = 25·x shows a proportional relationship
a = 5·x + 5 does not show a proportional relationship
m = 105.25·n shows a proportional relationship
Step-by-step explanation:
An equation that shows a proportional relationship is of the form, y = kx
Where;
k = The constant of proportionality = y/x
Therefore, the equation, y = 25·x shows a proportional relationship
The constant of proportionality = k = y/x = 25
Similarly, the equation m = 105.25·n shows a proportional relationship
The constant of proportionality = k = m/n = 105.25
When the equation shows a proportional relationship, the graph of the equation passes through the origin, therefore, the equation of the form, y = m·x + c, where c = the y-intercept > 0, the equation does not show a proportional relationship
The equation a = 5·x + 5, which is of the form, y = m·x + c, with c = 5 > 0, therefore, does not show a proportional relationship.
Therefore;
y = 25·x shows a proportional relationship
m = 105.25·n shows a proportional relationship
a = 5·x + 5 does not show a proportional relationship.
