Erika write the following word expression on the board: The quotient of 24 and k. Write an algebraic expression for the word expressions. THEN evaluate (solve) the expression for k = 3
Answer:
a) x=24/k
b) x=24/3
x=8
Step-by-step explanation:
Quotient meant division and you are trying to find the quotient (x) so you divide 24 by 3 to get 8
If f(x) = 3x - 15, what is f(4)?
A. 3
B. -3
c. 12
D. -8
Answer:
B. -3
Step-by-step explanation:
f(x) = 3x - 15
f(4) means x=4, so you want to plug 4 into the equation.
f(4) = 3(4) - 15
f(4) = 12 - 15
f(4) = -3
Answer:
B
Step-by-step explanation:
f(4) has the same meaning (for this question ) as x = 4
Let x = 4
f(4) = 3*4 - 15
f(4) = 12 - 15
f(4) = - 3

ANSWER CORRECTLY WITH SHOWN WORK, PLEASE AND HURRY!!
Answer:
[tex]y=\frac{5+8x}{10} , x=x[/tex]
Step-by-step explanation:
y-0.8x=0.5
y*10-0.8x*10=0.5*10
10y-8x=5
10y-8x+8x=5+8x
10y/10=5/10+8x/10
y=5+8x/10
5*5+8x/10-2.5
8x+5/2-2.5=4x
y=5+8x/10, x=x

There are 15 people on a bus. Some are adults. Some are children. There are more adults than children. Write down three different ratios of adults to children on the bus.
Answer:
Step-by-step explanation:
A ratio would mean that for every x number of adults there are a y number of children and the total in this scenario would need to total the 15 individuals in the bus. Therefore, since there has to be more adults than children then any of the following three ratios would be valid.
10 adults :: 5 children
14 adults :: 1 children
5 adults :: 3 children
All three of these ratios add up to be the 15 total individuals in the bus and also fit the requirement that there are more adults tan children.
2. Which of the following is the correct interpretation of confidence interval? (circle one)
a. If the same experimental process is done on many samples, with a given percentage certainty,
the population parameter will fall within a calculated range.
b. When many different processes are done on the same sample, with a given percentage certainty,
the population parameter will fall within a calculated range.
c. If the same experimental process is done on many samples, with a given percentage certainty,
each sample will determine its own calculated range with a given percentage certainty
3. In a certain study, a population parameter is predicted to be in the interval (42, 60) at a 95% confidence
level. What is a reasonable confidence interval if the confidence level is adjusted to 98%

Find the composition of transformations that map ABCD to EHGF. 3 Reflect over the [? ]-axis , then translate (x+[ ],y+[ 1) . 2
Answer:
x3 y1
Step-by-step explanation:
ABCD reflects over [tex]X-[/tex] axis.
Then translated to [tex](x+[6],y+[-1])[/tex].
What is Transformation?A single or multiple changes in a geometrical shape or figure is called Geometrical Transformation.
What is Reflection?A geometrical transformation in which a geometrical figure changes his position to his mirror image about some point or line or axis is called Reflection.
We can see in the given figure that ABCD becomes EHGF after reflecting over [tex]X-[/tex] axis.
So now A became the point E.
We can see in the figure that the coordinates of A were [tex](-5,2)[/tex]
And now the coordinates of E are [tex](1,1)[/tex]
So, [tex](-5+[6],2+[-1])=(1,1)[/tex]
Hence the transformation is [tex](x+[6],y+[-1])[/tex].

Find the product for 1.29 x 5.4
show work please <3.
Answer:
6.966
Step-by-step explanation:
•Mark how many you have in the d.p
•If there is two or more add them up
•Multiply like normal given numbers
•Write where the decimal point is to be
Hope that helps
The answer you are looking for is 6.966. You multiply the numbers as normal, the place the decimal based off of how many numbers are behind the 2 decimal points given. 1.29 has 2 numbers behind the decimal, and 5.4 has 1. 1 + 2 = 3, so from the right of the last number on the right side, you move the decimal 3 places.
Here's an image to show you how I solved the problem.

Linda has to buy stickers, erasers, and a pencil. She can only spend $3. A sticker costs $0.35, an eraser costs $0.99, and a pencil costs $0.59. Can Linda buy 3 stickers and 2 erasers?
[Use the inequality 0.35x + 0.99y + 0.59 ≤ 3]
Answer:
No
Step-by-step explanation:
Step 1: Understand the inequality
The inequality 0.35x + 0.99y + 0.59 ≤ 3 contains 2 variables 'x' and 'y'. We can see the 'x' is multiplied by 0.35 which is the price of a sticker which means 'x' represents how many stickers Linda is buying. The 'y' is multiplied by 0.99 which is the price of a eraser which means 'y' is how many erasers Linda is buying. We ignore the 0.59 as that's the price for a pencil but Linda doesn't buy a pencil
Step 2: Sub in the values
[tex]0.35(3)+0.99(2)<3\\1.05+1.98<3\\3.03<3[/tex]
Step 3: Interpret the answer
Because the equality isn't true we can conlude Linda doesn't have the money to buy 3 stickers and 2 erasers
Answer:
no
Step-by-step explanation:
0.35x3=$1.05
0.99x2=$1.98
add $0.59+$1.98+$1.05
=$3.62
If f(x)=2x, where is the y−intercept of g(x)=f(x)+4?
Given:
[tex]f(x)=2x[/tex]
[tex]g(x)=f(x)+4[/tex]
To find:
The y-intercept of g(x).
Solution:
We have,
[tex]g(x)=f(x)+4[/tex]
Putting [tex]f(x)=2x[/tex], we get
[tex]g(x)=2x+4[/tex]
Substitute x=0 to find the y-intercept of g(x).
[tex]g(0)=2(0)+4[/tex]
[tex]g(0)=0+4[/tex]
[tex]g(0)=4[/tex]
Therefore, the y-intercept of g(x) is at point (0,4). So, the y-intercept of g(x) is 4.

Write an equation using slope intercept form when m=4 and b=12
Answer:
y = 4x + 12
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
since you're given the values for m and b, all you need to do is plug those into the equation for slope-intercept form.
plug in 4 for m.
y = mx + b ⇒ y = 4x + b
plug in 12 for b.
y = 4x + b ⇒ y = 4x + 12
it doesn't matter which one you plug in first as long as you plug the value in for the correct variable.
the equation of your line in slope-intercept form is y = 4x + 12. i hope this helps! have a great day <3
