Enter the correct answer in the box. the function f(x) = 2x − 1 is transformed to function g through a horizontal shift of 7 units left. what is the equation of function g? replace the values of h and k in the equation.
Answers
The equation of function g(x) is g(x) = 2(x -7)² - 1, and the values of h and k are 7 and -1, respectively
How to transform the function?The function is given as:
f(x) = 2x² - 1
When the function is translated 7 units left, the transformation rule is:
(x,y) -> (x + 7, y)
So, we have:
g(x) = 2(x -7)² - 1
A quadratic function is represented as:
g(x) = a(x -h)² + k
By comparison, the values of h and k are 7 and -1, respectively

Akira ordered a set of beads. She received 100 beads in all. 8 of the beads were green. What percentage of the beads were green?
Answers
Answer:
8%
Step-by-step explanation:
8 out of 100 are green
8/100 * 100% = 8 %
Answer:
8% of the beads are green
Step-by-step explanation:
Step 1: Determine what percentage of the beads are green
This problem is known as a probability problem which basically tries to determine the proportionality between certain numbers. In this example we are trying to figure out the proportionality between the green beads and the total sample.
(8 green beads) / (100 total beads)
0.08
0.08 is the probability but if we want to determine what the percentage is of the number we just multiply it by 100.
0.08 * 100 = 8%
Answer: 8% of the beads are green

Decide whether y is a function of x.
2x + y = 7
Answers
2x + y = 7, y is a function of x
Explanation:
2x + y = 7 is a function
===================
Rewrite into slope intercept form
y = 7 - 2x
y = -2x + 7
It is a linear equation (straight line)The vertical line touches the graph only one time. Thus y is a function of x.
Answer:
Given equation: [tex]2x+y=7[/tex]
Definition of a function
A relation is a function if each y-value corresponds to one or more x-values.A relation is not a function if each x-value corresponds to more than one y-value.The given function is in the standard form of a linear equation: [tex]ax+by=c[/tex]
If the given equation is rearranged to make y the subject:
[tex]y=-2x+7[/tex]
it is now in the general form of a linear equation, [tex]y=mx+b[/tex] (where m is the slope and b is the y-intercept).
A linear equation is one of a straight line, and so, by definition, each value of y corresponds to one value of x. Therefore, this is a one-to-one function.

A storage container consists of a box of length 90cm, width 42 cm and height 34 cm, and a lid
in the shape of a half-cylinder, as shown in the diagram. The lid fits the top of the box exactly.
The total exterior surface of the storage container is to be painted.
Find the area to be painted.
Answers
Answer:
20079.05 cm^2,
Step-by-step explanation:
Surface area of the box without the lid
= 90*42 + 2(90*34) + 2(42*34) = 12756.
Now find Surface area of the half cylinder:
The diameter of the 2 half circles = 42 so the radius = 21.
The area of the lid
= 2 + 1/2 π (21)^2 + π r * 90
= 7323,052
Total = 20079.052

how many nickels will you need to buy a candy bar that's 20 c
Answers
Answer:
4 Nickles
Step-by-step explanation:
to find this out we can devide the total cost (20 ¢) by the worth of the coin we are using (1 Nickel = 5 ¢) as shown below
20 ÷ 5 = 4
what this equation shows is that 4 nickels are needed to add up to a total of 20 ¢

side note, i dont usually say this but at the moment i am 2 crowns away from my next level, so if the answer seems fit to you a crown would be, depending on the other answer, thank you
EDIT:
Additional Example
this method can be applied to most situations, even if you need multiple coin types
say Ron wants to buy a 57 ¢ apple pie slice in exact change, lets assume he has a surplus in the four common coins in his wallet book or pocket
first he uses a quarter and divides as follows
57 ÷ 25 = 2 with a remainder of 7
then he can take a coin of less value then the remainder (in this case a nickel since 5 < 7, and not a dime since 10 > 7)
7 ÷ 5 = 1 with a remainder of 2
and finally with the pennies
2 ÷ 1 = 2
with this info we know that Ron will need 2 quarters, 1 nickel and 2 pennies to have exact change in the least amount of coins
